Saskatchewan’s new Climate Change Strategy: reckless endangerment

Graph of Saskatchewan greenhouse gas emissions relative to selected nations
Saskatchewan greenhouse gas emissions relative to selected nations

Saskatchewan’s greenhouse gas emissions are extremely high: 66 tonnes per person per year.  What if Saskatchewan was a country, instead of a province?  If that were the case, we’d find that no country on Earth had per-capita emissions higher than ours.

This week’s graph compares per-capita greenhouse gas (GHG) emissions in Saskatchewan to emissions in a variety of countries.  The units are tonnes of carbon dioxide equivalent (CO2-eq).  The data is for the years 2014 and 2015, the most recent years for which data is available.  The graph shows that Saskatchewan’s emissions are higher than those of petro-states such as Saudi Arabia and Qatar and manufacturing nations such as China and Germany.

Our world-topping per-person emissions form part of the context for this week’s release of the Government of Saskatchewan’s climate strategy: Prairie Resilience: A Made-in-Saskatchewan Climate Change Strategy.  The report isn’t really a plan of action—more an attempt at public relations and a collection of re-announcements.   Most critically, it lacks a specific set of measures that can, taken together, enable citizens and businesses in this province to reduce our GHG emissions by 30 percent by 2030.  I’ll review some of the key points of the document, but first just a bit more context.

In Paris in 2015, the world’s governments reaffirmed a target of limiting global temperature increases to 2 degrees Celsius (relative to pre-industrial levels).  However, more and more scientists are warning that 2 degrees is not a “safe level,” and that temperature increases of this magnitude will create floods, droughts, storms, and deaths in many parts of the world.  But a 2 degree rise is better than 4 or 5 degrees.

So that’s the first point: our 2 degree target is weak.  To this we’ve added inadequate emission-reduction commitments.  In the lead-up to the Paris climate talks the world’s governments each submitted specific emission-reduction commitments.  Canada committed to cut this country’s emissions by 30 percent (below 2005 levels) by 2030.  Other nations made similar pledges.  But here’s the troubling part: When you add up all those emissions-reduction commitments you find that they put the world on track, not for 2 degrees of warming, but for 3.2 degrees (UN Emissions Gap Report 2017).  So this is the context for recent climate change strategies from Saskatchewan and other provinces: These plans amount to inadequate provincial contributions to an inadequate national commitment to a weak international target.

One final bit of context: not only are per-capita emissions in Saskatchewan among the highest in the world, they continue to increase: up 65 percent in a generation (1990 to 2015).  Some will want to excuse our province: it’s cold here.  But our per-capita emissions are almost twice as high as those in the Northwest Territories, nine times as high as in the Yukon, and four times as high as those in neighbouring Manitoba.  Others will want to talk about the fact that Saskatchewan is a resource-producing and agricultural province; our prosperity depends upon our ability to keep farming and mining and producing oil and gas.  There’s a grain of truth to some parts of that idea, but it simply cannot be the case that “prosperity” requires the emission of 66 tonnes of GHGs per person.  Citizens in every nation want prosperity.  But if everyone in the world felt entitled to emit GHGs at the same rate as us, there would soon be no Saskatchewan as we know it.  There would be a parched desert here, and submerged cities worldwide.  In a climate- and carbon-constrained world, prosperity simply cannot require Saskatchewan-sized emissions.

So, with this for context, what does the Saskatchewan Climate Change Strategy propose?  The government has re-committed to increasing the production of low-emission electricity—to the “expansion of renewable energy sources up to 50 per cent of generating capacity” by 2030.  This is good news and we must ensure that this happens, well before 2030, if possible.  But careful readers might note three things in the preceding commitment:  1. the words “up to.”  2. generating capacity is not the same as output; because of the intermittent nature of wind power, for example, 50 percent of capacity will not equate to 50 percent of production.  3. electricity provides less than 30 percent of Saskatchewan’s total energy demand.  Thus, moving to 50 percent renewable/low-emission sources for electricity leaves 80+ percent of Saskatchewan’s energy needs filled by high-emission fossil fuels.

The Climate Change Strategy includes the creation of a technology fund.  But this is not new.  The government passed legislation in 2010 requiring large emitters to pay into a green technology fund.  That law was never put into force.

Predictably, the Strategy rejects a carbon tax, arguing that such a tax “would make it more difficult for our province to respond effectively to climate change because a simple tax will not result in the innovations required to actually reduce emissions.”

The Strategy also includes a vague mix of commitments to reporting, potential future measures to reduce methane emissions, emission-intensity targets, and offset trading.  Think of this as a cap-and-trade system without a cap.

The Strategy includes some positive steps but fails to deliver what we need: a comprehensive, detailed plan that will result in a 30 percent reduction in emissions by 2030.  This failing is especially evident when one takes into account probable emissions increases that may result from economic growth, planned increases in energy production, and increased use of agricultural inputs such as nitrogen fertilizer.  (Applied tonnage of N fertilizer has doubled since 2002.)

Overall, the Strategy steers away from discussions of emissions reduction and focuses instead on the idea of “resilience.”  That word appears 44 times in 12 pages.  The report defines resilience as “the ability to cope with, adapt to, and recover from stress and change.”  But resilience—coping, adapting, and recovering—may simply prove impossible in the face of the magnitude of climate change that will scorch our province under a business-as-usual scenario.  The high-emission, fossil-fuel-dependent future assumed in the Climate Change Strategy would raise the average temperature of this province by 6 to 8 degrees Celsius (sources available on request).  Climate disruption of that magnitude vetoes adaptation and mocks resilience.

And even if we in Saskatchewan could find ways to adapt and make ourselves resilient in the face of the blows that may be inflicted by a hotter, stormier, more damaging climate, we must ask: Will poor and vulnerable populations around the world be able to make themselves “resilient” to the climate change that our emissions trigger?   The global proliferation of Saskatchewan-level emissions would cause cities to disappear under the waves, food-growing regions to bake and wither, and tropical storms to become more numerous and damaging.  What is our ethical position if we are among the greatest contributors to these calamities, yet all we offer affected populations is the advice to make themselves more resilient?

A real plan is possible.  Emission reductions of 30 percent by 2030 are attainable at costs that Saskatchewan can afford.  Holding global temperature increases to 2 degrees also remains possible.  All this can be accomplished if governments act with courage and integrity, rapidly and effectively, and in the interests of citizens and the future.

Geoengineering: 12 things you need to know

Graphic showing various geoengineering methods

The following draws upon extensive research by ETC Group.  I have been privileged to serve on ETC’s Board of Directors for several years. 

1.  What is “geoengineering”?  It is the intentional, largescale, technological manipulation of Earth’s systems.  Geoengineering is usually discussed as a solution to climate change, but it could also be used to attempt to de-acidify oceans or fix ozone holes.  Here, I’ll concentrate on climate geoengineering.

2.  There are two main types of climate geoengineering:
i. Technologies to partially shade the sun in order to reduce warming (called “solar radiation management” or SRM).  For example, high-altitude aircraft could be used to dump thousands of tonnes of sulphur compounds into the stratosphere to form a reflective parasol over the Earth.
ii. Attempts to pull carbon dioxide (CO2) out of the air.  One proposal is ocean fertilization.  In theory, we could dump nutrients into the ocean to spur plankton/algae growth.  As the plankton multiply, they would take up atmospheric CO2 that has dissolved in the water.  When they die, they would sift down through the water column, taking the carbon to the ocean floor.

3.  The effects of geoengineering will be uneven and damaging.  For example, sun-blocking SRM technologies might lower the global average temperature, but regional temperature changes would probably be uneven.  Other geoengineering techniques—cloud whitening and weather modification—could similarly alter temperatures in some parts of the planet relative to others.  And if we change relative regional temperatures we would also shift wind and rainfall patterns.  Geoengineering will almost certainly cause droughts, storms, and floods.  Going further, however, all droughts, storms, and floods (even those that might have occurred in the absence of geoengineering) could come to be seen as caused by geoengineering and the governments controlling those climate interventions.  If we go down this path, there will no longer be any “acts of God”; weather will become a product of government.

4.  These technologies are dangerous in other ways.  Seeding the stratosphere with sulphur particles could catalyze ozone depletion.  Shifts in rain and temperature patterns may cause shifts in ecosystems and wildlife habitats.  Multiplying plankton biomass may affect fish species distribution and biodiversity.  Moreover, as with any enormously powerful technology, it is simply impossible to foresee the full range of unintended consequences.

5.  Geoengineering is unilateral, undemocratic, inequitable, and unjust.  In a geoengineered world, who will control the global thermostat?  Solar radiation management and similar schemes will inevitably be controlled by the dominant governments and corporations—a rich-nation “coalition of the dimming.”  But benefits and costs will be distributed unequally, creating winners and losers.  Where will less powerful nations appeal if they find themselves on the losing end?  Our climate interventions will be calibrated to maximize benefits to rich nations: the same countries that have benefited most from fossil fuel combustion and that have caused the climate crisis.  We appear to be contemplating a triple injustice: poor nations will be denied their fair share of the benefits of fossil fuel use; hit hardest by climate change; and left as collateral damage from geoengineering.  Finally, geoengineering is undemocratic in another way.  It is a choice to pursue technical interventions rather than social or political reforms.  It reveals that many governments and elites would risk damaging the stratosphere, hydrosphere, and biosphere rather than risk difficult conversations with voters, CEOs, or shareholders.

6.  Geoengineering embodies and proliferates a certain worldview: masculine, nature-dominating, imperialistic, managerial and technocratic, hostile to limits, and hubristic.

7.  Geoengineering will create conflicts.  Because technologies such as SRM are transboundary and have the potential to shift weather patterns they can lead to charges that other nations are stealing rain and, ultimately, food.  To get a sense of the potential for conflict, imagine the US reaction to unilateral deployment of weather- and climate-altering technologies by Russia or China.

8.  It is untestable.  Small-scale experiments with SRM or similar technologies will not reveal potential side-effects.  These will only become evident after planet-scale deployment, and perhaps years after the fact, as weather systems move toward new equilibria.

9.  Deployment may be irreversible.  Once we start we might not be able to stop.  Geoengineering would probably proceed alongside continued greenhouse gas (GHG) emissions.  But if we deploy sun-blocking technologies and simultaneously push atmospheric CO2 levels past 500 or 600 parts per million, we wouldn’t be able to terminate our dimming programs, no matter how damaging the effects of long-term geoengineering are revealed to be.  If we did stop, high GHG levels would trigger sudden and dramatic warming.  We risk locking ourselves into untestable, unpredictable, uncontrollable, and planet-altering technologies.

10. Can geoengineering “buy us time”?  Proponents argue that these technologies can buy us some time: time humanity needs in order to ramp up emissions reductions.  But geoengineering is more likely to buy time for the status quo, to prolong unsustainable fossil fuel production and energy inefficiency, and to blunt and delay urgent and effective action.  The effect of geoengineering is not so much to buy time as to waste time.

11. There will be attempts to pressure us into accepting geoengineering.  Geoengineering proponents may soon raise the alarm and claim that we must accept these risky technologies or face even worse damage from climate change.  “Desperate times call for desperate measures,”  they will say.  From these same sources may come arguments that geoengineering is necessary to hold global average temperature increases below 1.5 or 2 degrees and thus spare the world’s poorest and most vulnerable peoples.  Such arguments would be both ironic and duplicitous.  The same government and corporate leaders who today deny or downplay climate change, or deny the need for rapid action to cut emissions, may tomorrow be the one’s raising the alarm, and claiming that there is no solution other than geoengineering.  They may pivot from claiming that there is no problem to claiming that there is no alternative.

12. Geoengineering will be pushed by the rich and powerful.  A growing number of corporations, elites, and politicians see the solution to climate change, not in emissions reduction, but in massive techno-interventions into the atmosphere or oceans to block the sun or suck up carbon.  When he was CEO of Exxon, US Secretary of State Rex Tillerson said of climate change: “It’s an engineering problem, and it has engineering solutions.”  Exxon employs many geoengineering proponents and theorists.  Former executive at oil company BP and former Under-Secretary for Science in the Obama administration Steven Koonin is lead author of a report entitled Climate Engineering Responses to Climate Emergencies.   Virgin Airlines CEO Richard Branson offered a $25 million prize to anyone who could solve climate change by geoengineering.   Bill Gates and other Microsoft billionaires are funding geoengineering research.  Newt Gingrich is the former speaker of the US Congress and a Vice Chairman of Donald Trump’s transition team.  His views on geoengineering are worth quoting because they may be representative of a growing sentiment among political and corporate leaders.  Gingrich wrote in a 2008 fundraising letter:

“[T]he idea behind geoengineering is to release fine particles in or above the stratosphere that would then block a small fraction of the sunlight and thus reduce atmospheric temperature.

… Instead of imposing an estimated $1 trillion cost on the economy …, geoengineering holds forth the promise of addressing global warming concerns for just a few billion dollars a year.  Instead of penalizing ordinary Americans, we would have an option to address global warming by rewarding scientific innovation.

My colleagues at the American Enterprise Institute are taking a closer look at geoengineering, and we should too.  …

Our message should be: Bring on the American Ingenuity.  Stop the green pig.”


For reasons outlined above and many others, we must not go down the path of geoengineering.  These technologies—massive government and corporate interventions into the core flows and structures of the atmosphere, hydrosphere, and biosphere—are among the most dangerous initiatives ever devised.  Geoengineering must be banned; it is untestable, uncontrollable, unjust, probably irreversible, and potentially devastating.  There exist better, safer options: rapid and dramatic emissions reductions; and a government-led mobilization toward a transformation of global energy, transport, industrial, and food systems.







Carbon tax will not cause fossil fuel use to fall: Canada’s NEB

Graph of Canadian fossil fuel use and NEB projections to 2040
Canadian fossil fuel use, historic and projections to 2040

The graph above is based on data from a recent report by Canada’s National Energy Board (NEB)—a federal government agency.  The October 26 report, Canada’s Energy Future 2017, predicts that Canadians will be consuming fossil fuels at the same rate in 2040 as we are today.  The NEB is projecting that fossil fuel use will not fall, nor will attendant greenhouse gas (GHG) emissions.

The graph’s blue bars show Canadian fossil fuel use over the past 11 years.  The brown line shows the NEB’s projections for the future.  The units, exajoules, are not important.  What is important is that the NEB predicts no drop in fuel consumption.

Most important, is that the NEB’s projections take into account the federal government’s carbon tax.  Ottawa has announced that the provinces must impose a carbon tax of $10 per tonne in 2018, escalating to $50 per tonne by 2022.  All provinces must impose a tax, or some equivalent carbon-pricing scheme.

At the Paris climate talks in 2015, Canada joined other nations in committing to limit the global average temperature increase to 2.0 degrees C (relative to pre-industrial levels).  To help achieve that goal, Canada has made an international commitment to reduce its GHG emissions by 30 percent (relative to 2005 levels) by 2030.  The NEB is, in effect, saying that Canada will fail to meet its commitment of a 30 percent reduction; the carbon tax, along with all other measures announced so far, will not cause a decline in fossil fuel use or emissions.

The preceding should surprise no one.  The federal government’s carbon tax starts out at $10 per tonne of carbon—equivalent to about 2¢ per litre of gasoline.  Over the next half-decade, it rises to $50 per tonne—about 11¢ per litre.  Many Canadians do not know the price of gasoline to the nearest dime.  And gasoline prices over the past year were down as much as 40¢ compared to three years ago.  An 11¢ per litre carbon tax is not going to cause gasoline consumption to fall.  Similarly modest taxes on other fuels will likewise prove ineffective.

Canadians need to understand that they are being deceived.  Politicians—eager for re-election and afraid of hard conversations with voters—are understating the magnitude of the climate crisis and overestimating the effectiveness of our actions to counter the threat.

How do we actually reduce fossil fuel use, cut emissions, and stabilize the climate?  A carbon tax is needed, but it must be much higher: $200 to $300 per tonne—equivalent to 50¢ to 75¢ per litre of gasoline.  But such a tax is unbearable for citizens (and politicians) unless 100 percent of the total tax collected is rebated back to citizens on a per-capita basis.  We need a carbon-tax-and-refund system.  Under such a system, we would all pay taxes on gasoline, home heating fuel, etc. and pay indirectly on the energy embedded in our products.  Goods that required a lot of energy to produce or transport would cost more.  But offsetting these new costs, we would receive back all the carbon tax money collected, on a per-capita basis.  Thus, if a person’s energy consumption is below average, he or she would finish the year money ahead—his or her per-capita refund would exceed the carbon taxes paid.  On the other hand, someone who wants to drive a Hummer and heat and cool a huge home will come out money behind.  Another way of thinking about this tax-and-refund system is that it transfers money to those doing the right things from those doing the wrong things.  And the former group can take their carbon tax refunds and invest them in home energy retrofits, solar panels, and other emission-reduction measures, setting the stage for even larger carbon tax savings next year.

The NEB is telling us we’re not on track.  But we can change course.  Bold and rapid policy action now can reduce emissions by 30 percent and help limit temperature increases to 2 degrees.  But we must act.

A critically important solution to our climate crisis (and other crises)

Reconstructed wreckage of TWA Flight 800
US National Transportation Safety Board (NTSB) reconstruction of wreckage from TWA Flight 800

Ronald Wright’s A Short History of Progress is available as a book and as a five-part audio series—the 2004 CBC Massey Lectures.  (Listen here.)  In both its written and oral forms, A Short History of Progress is an accessible, eye-opening tour of humanity’s long historic journey—a look at the big picture and the long term.  It is aphoristic and packed with insights.  But one idea stands out.  Wright gets at this important idea by using the analogy of plane crashes.

Air travel today is very safe.  Mile for mile, your chances of being killed or injured while traveling on a commercial jetliner are about one one-hundredth your chances of suffering the same fate in your own car.  In 2016, zero people died in crashes of a US-based airlines operating anywhere in the world—the seventh year in a row that this was true (source here).

There’s a reason that airliners have become so safe: after every crash, well-resourced teams of highly-trained aviation experts are tasked with determining why a crash occurred, and once the cause is known the entire global aviation system implements changes to ensure that no plane in the future crashes for the same reasons.

Government agencies and airlines often expend enormous efforts to determine the cause of a crash.  The photograph above is of the reconstructed wreckage of TWA Flight 800, a Boeing 747 that crashed in 1996 after its fuel tank exploded, splitting the plane apart just ahead of the wings.  The plane crashed into the ocean off the coast of New York.  All 230 people aboard died.

The debris field covered several square miles.  In a massive effort, approximately 95 percent of the plane’s wreckage was salvaged from the sea.  The plane was painstakingly reconstructed.  And using the reconstructed plane as well as the flight data and cockpit voice recorders, the cause of the failure was traced back to a short circuit in wiring connected to the “fuel quantity indication system” in the centre fuel tank.  As a result of this investigation, changes were made to planes around the world to ensure that no similar crashes would occur.  As a result of crash investigations around the world, airlines and aircraft makers have made thousands of changes to airplane construction, crew training, air traffic control, airport security, airline maintenance, and operating procedures.  The results, as noted above, have been so successful that some years now pass without, for instance, a single fatality on a US airline.

Ronald Wright argues that the ruins and records of fallen civilizations can be investigated like airplane crash sites, and we can use the lessons we learn to make changes that can safeguard our current global civilization against similar crashes.  He writes that these ruined cities and civilizations are like “fallen airliners whose black boxes can tell us what went wrong” so that we can “avoid repeating past mistakes of flight plan, crew selection, and design.”  When Wright talks metaphorically about “flight plan,” consider our own plan to increase the size of the global economy tenfold, or more, this century.  And when he talks about crew selection, think about who’s in the cockpit in the United States.

Wright continues: “While the facts of each case [of civilizational collapse] differ, the patterns are alarmingly … similar.  We should be alarmed by the predictability of our mistakes but encouraged that this very fact makes them useful for understanding what we face today.”

Wright urges us to deploy our archaeologists, historians, anthropologists, ecologists, and other experts as crash-scene investigators—to read “the flight recorders in the wreckage of crashed civilizations,” and to take what we learn there and make changes to our own.  It is good advice.  It is, perhaps, the best advice our global mega-civilization will ever receive. 

While the crash of a jetliner may kill hundreds, the crash of our mega-civilization could kill billions.  And as more passengers pile in, as our global craft accelerates, and as the reading on the fuel-gauge drops and our temperature gauge rises, we should become more and more concerned about how we will keep our civilizational jetliner aloft through the storms to come.

Setting our future aflame: Projected energy use to 2035

Global primary energy use, by source or fuel, 1965 to 2015, with projections to 2035 (billions of tonnes of oil equivalent)

In a recent post (link here) I said that holding global temperature increases below dangerous levels would require “a mobilization of near-wartime scale and speed to transform the global economy and its energy and transportation systems.”  Most climate scientists looking at carbon budgets agree that global greenhouse gas emissions need to fall to near zero in the 2040s (to hold temperature increases below 1.5 degrees Celsius) or 2050s (to hold increases to 2 degrees).

So, how are we doing?  BP (formerly British Petroleum) is one of the world’s leading sources for energy statistics and projections.  This week’s graph is taken from the 2017 edition of its Energy Outlook.  The graph shows BP’s projections of energy use to 2035, based on current trends.  The picture is bleak.

BP’s projections show oil use/combustion rising over the next 18 years.  Natural gas combustion rises even faster.  Even coal combustion increases.  Not surprising, BP projects rising GHG emissions for the period from 2017 to 2035.  But this is exactly the time frame in which we are supposed to be rapidly reducing emissions.

If BP is correct, if we act in the ways they are predicting, there is zero chance of meeting the Paris commitments of reducing GHG emissions by 30 percent by 2030.  And there is zero chance of holding temperature increases below 2 degrees.  The picture BP paints, if we allow it to come to pass, would push global temperature increases past 3 degrees, or even higher.  That would be a cataclysmic amount of warming.

I’m told that fear and bad news are not good motivators.  But neither are delusion or denial.  We must stop telling ourselves fanciful stories about salvation by solar shingles.  The citizens of the world need to know the facts about our situation and our trajectory.  There is a vague feeling that we’re doing the right thing, that solar and wind power are growing so fast that we can meet our targets, that a modest carbon tax levied sometime in the future will be enough to put us onto the right track.  No.  Projections by BP and others tell a wholly different story.  The facts indicate that we are on track to climate calamity.  That may not be welcome news, but it is the truth.  Whether it motivates people remains to be seen.

Cattle Rustling? The growing gap between cattle and beef prices

Graph of Canadian cattle prices and retail beef prices, 1995 to 2017
Retail prices of ground beef and steak compared to farmers’ prices for cattle, 1995–2017

This week’s graph highlights the growing gap between what Canadians pay for beef and what farmers receive for their cattle.  The rising blue lines show grocery-store prices for steak and ground beef.  The comparatively flat green lines represent the prices farmers and feedlot operators receive for the cattle they sell to beef packers.  Steers (castrated male cattle) are more likely to be the source of steaks, while cows are primarily turned into ground beef.

The blue lines show what consumers pay; the green lines show what farmers get.  The widening gap between the blue lines and the green lines reveals the amount that packers and retailers take for themselves.

Let’s look first at the dotted lines.  The green dotted line shows the per-pound price farmers in Alberta receive for their cows.  (prices across Canada are similar.)  In the decade-and-a-half before 2010, that price averaged about 50¢.  In recent years it has averaged about $1.00.  One could say that farmers are receiving an extra 50¢ per pound for their cows.  These figures do not take into account rising costs (they are not adjusted for inflation) but we’ll leave that issue aside for now.  Note what happens to the blue dotted line: the grocery-store price of ground beef.  It more than triples, from about $1.70 per pound to about $5.50.  Farmers’ prices increased by 100%, but packers and retailers increased their take by 320%.  Farmers’ prices increased by 50¢, but packers and retailers increased their prices by nearly $4.00.

The solid green line shows the price that farmers (or feedlot operators) receive for slaughter-ready steers.  The solid blue line is a representative price for grocery-store steaks.  If we compare recent years to those before 2013, we see that steer prices have risen by perhaps 50¢ or 60¢ per pound.  Over the same period, steak prices have risen by $5.00 or $6.00.

There is little discernible connection between the prices consumers pay and the prices farmers receive.  This is true of cattle and beef, but also true of nearly every other farm-retail product pair.  For a graph comparing the prices of wheat and bread, click here.  Similar “wedge” graphs can be created for corn and cornflakes, hogs and pork chops, and many other farm-retail product pairs.

Food processors, packers, and retailers are choking off the flow of dollars to Canadian farms, with devastating effects.  The number of Canadian farms raising cattle has been cut nearly in half in a generation—from 142,000 in 1995 to less than 75,000 today.  Moreover, many of these farms reporting cattle are dairy farms (which do sell cattle for slaughter, but support themselves primarily from milk sales).  The number of farms classified as “beef cattle ranching and farming, including feedlots” stood at just 36,000 in 2016.  Farm debt is a record $100 billion.  And the number of young farmers (<35 years of age) today is just one-third the number a generation ago.

Canadians are paying many times over.  We’re paying a high price at the store.  We’re paying again through our taxes to fund farm support programs—money paid to farmers to backfill for the dollars extracted by powerful transnational packers, processors, and retailers.  And we’re paying yet again as our rural economies are hollowed out, our communities decimated, our family farms destroyed, and our nation’s capacity to sustainably produce food is eroded.

Everything must double: Economic growth to mid-century

Graph of GDP of the world's largest economies, 2016 vs 2050
Size of the world’s 17 largest economies, 2016, and projections for 2050

In February 2017, global accounting firm PricewaterhouseCoopers (PwC) released a report on economic growth entitled The Long View: How will the Global Economic Order Change by 2050?  The graph above is based on data from that report.  (link here)  It shows the gross domestic product (GDP) of the largest economies in the world in 2016, and projections for 2050.  The values in the graph are stated in constant (i.e., inflation adjusted) 2016 dollars.

PwC projects that China’s economy in 2050 will be larger than the combined size of the five largest economies today—a list that includes China itself, but also the US, India, Japan, and Germany.

Moreover, the expanded 2050 economies of China and India together ($102.5 trillion in GDP) will be almost as large as today’s global economy ($107 trillion).

We must not, however, simply focus on economic growth “over there.”  The US economy will nearly double in size by 2050, and Americans will continue to enjoy per-capita GDP and consumption levels that are among the highest in the world.  The size of the Canadian economy is similarly projected to nearly double.   The same is true for several EU countries, Australia, and many other “rich” nations.

Everything must double

PwC’s report tells us that between now and 2050, the size of the global economy will more than double.  Other reports concur (See the OECD data here).  And this doubling of the size of the global economy is just one metric—just one aspect of the exponential growth around us.  Indeed, between now and the middle decades of this century, nearly everything is projected to double.  This table lists just a few examples.

Table of projected year of doubling for various energy, consumption, transport, and other metrics
Projected year of doubling for selected energy, consumption, and transport metrics

At least one thing, however, is supposed to fall to half

While we seem committed to doubling everything, the nations of the world have also made a commitment to cut greenhouse gas (GHG) emissions by half by the middle decades of this century.  In the lead-up to the 2015 Paris climate talks, Canada, the US, and many other nations committed to cut GHG emissions by 30 percent by 2030.  Nearly every climate scientist who has looked at carbon budgets agrees that we must cut emissions even faster.  To hold temperature increases below 2 degrees Celsius relative to pre-industrial levels, emissions must fall by half by about the 2040s, and to near-zero shortly after.

Is it rational to believe that we can double the number of cars, airline flights, air conditioners, and steak dinners and cut global GHG emissions by half?

To save the planet from climate chaos and to spare our civilization from ruin, we must—at least in the already-rich neighborhoods—end the doubling and redoubling of economic activity and consumption.  Economic growth of the magnitude projected by PwC, the OECD, and nearly every national government will make it impossible to cut emissions, curb temperature increases, and preserve advanced economies and stable societies.  As citizens of democracies, it is our responsibility to make informed, responsible choices.  We must choose policies that curb growth.

Some good news on climate change

Graph adapted from Millar et al.
A graph produced by Millar et al. illustrating their re-assessment of carbon budgets.

A September 18th article in the journal Nature Geoscience provides some good news in the struggle to save human civilization (and perhaps half the planet’s species) from the ravages of climate change.  The article by Richard Millar and nine colleagues calculates that there is still time to hold global temperature rise to 1.5 degrees Celsius above pre-industrial temperatures.  (Article link is here.)

A 1.5 degree target was set in Paris in 2015.  While many people assert that holding temperature increases to 1.5 degrees is impossible, Millar et al. reassess carbon budgets to show that the target is attainable.  By their calculations, humans can emit an additional 700 to 900 billion tonnes of CO2 and still have a 66% chance of holding temperature increases below 1.5 degrees.  That amount of CO2 is approximately equal to 20 years of emissions at current rates.  (Previous assessments indicated that the carbon budget for 1.5 degrees would be used up in 5 to 7 years at current emission rates.)

The findings in the Millar paper are good news.  Here’s why: they take away the argument that “it’s too late.”  We still have it within our power to hold temperature increases below dangerous levels, spare low-lying island nations, prevent the inundation of rich river-delta agricultural lands in Bangladesh and elsewhere, retain the Greenland ice sheet, and prevent the worst ravages of climate change.  Here’s the message everyone should hear: It’s not too late.

But while it’s not too late, it is late.  The other message people should take from this article is that we have no time to spare.  Aggressive action is necessary now.  If we are to save ourselves from ourselves we must embark on a mobilization of near-wartime scale and speed to transform the global economy and its energy and transportation systems.  We need government-led mobilization for transformation.

The article’s lead author, Richard Millar, wrote a commentary stating that “the window for achieving 1.5C is still narrowly open.  If very aggressive mitigation scenarios can be implemented from today onwards, they may be sufficient to achieve the goals of the Paris Agreement.”  (Find that commentary here.)  At a press event he stated that holding increases to 1.5 degrees requires “starting reductions immediately and then reducing emissions to zero over 40 years.”  Like nearly everyone else who has looked at this issue, Millar and his team have concluded that emissions reductions must begin immediately and emissions from the global economy must be reduced to zero by the 2050s or 2060s.

So here’s where we are: Millar et al. calculate that we have the time (if only just).  We have the technologies: solar panels, wind turbines, electric trains, net-zero and passive solar homes.  We have historical examples of action on a similar scale: the WWII repurposing of the major industrial economies.  And we have the productive capacity: a global manufacturing sector of unprecedented scale and output.  Civilian and military aircraft makers must be compelled to immediately begin building trains.  Auto makers must build electric cars.  The home renovation industry must be redirected away from fantasy kitchens and home spas and toward energy-efficiency retrofits.  And electrical utilities must rapidly replace GHG-emitting generation plants with near-zero-emission alternatives.  And we must do all these things at rates that reflect that our future depends upon our success.

The calculations by Millar et al. are sure to be controversial and closely examined.  They may be revised.  But the paper has weight because the team that wrote it includes many of the leading experts on carbon budgets.  As climate scientist Glen Peter notes here: “the authors of this paper developed the idea of carbon budgets, are the world leading experts on carbon budgets, and derived the carbon budgets for the IPCC process.”  We should all hope that Millar and his colleagues are correct in their reassessment.

$20 TRILLION: US national debt, and stealing from the future

Debt clock showing that the US national debt has topped $20 trillion

Bang!  Last week, US national debt broke through the $20 trillion mark.  As I noted in a previous post (link here), debt of this magnitude works out to about $250,000 per hypothetical family of four.

Moreover, US national debt is rising faster than at any time in history.  Adjusted for inflation, the debt is seven times higher than in 1982 ($20 trillion vs. $2.9 trillion).  Indeed, it was in 1982—not 2001 or 2008—that US government debt began its unprecedented (and probably disastrous) rise.

The graph below shows US debt over the past 227 years.  The figures are adjusted for inflation (i.e., they are stated in 2017 US dollars).

It’s important to understand what is happening here: the US is transferring wealth from the future into the present.  The United States government is not merely engaging in some Keynesian fiscal stimulus, it is not simply borrowing for a rainy day (or 35 years of rainy days), it is not just taking advantage of low interest rates to do a bit of infrastructural fix-up or job creation, and it is not just responding to the financial crisis of 2008.  No.  The US government, the nation’s elites, its corporations, and its citizens are engaging in a form of temporal imperialism—colonizing the future and plundering its wealth.  They are today spending wealth that, if this debt is ever to be repaid, will have to be created by workers toiling in decades to come.

You cannot understand our modern world unless you understand this: Fossil-fueled consumer-industrial economies such as those in the US, Canada, and the EU draw heavily from the future and the past.

We reach back in time hundreds-of-millions of years to source the fossil fuels to power our cars and cities.  We are increasingly reliant on hundred-million-year-old sunlight to feed ourselves—accessing that ancient sunshine in the form of natural gas we turn into nitrogen fertilizer and enlarged harvests.  At the same time, we irrigate many fields from fossil aquifers, created at the end of the last ice age and now pumped hundreds of times faster than they refill.  We extract metal ores concentrated in the distant past.  And the cement in the concrete that forms our cities is the calcium-rich remnants of tiny sea creatures that lived millions of years ago.  We have thrust the resource-intake pipes for our food, industrial, and transport systems hundreds-of-millions of years into the past.

We also reach forward in time, consuming the wealth of future generations as we borrow and spend trillions of dollars they must repay; live well in the present at the expense of their future climate stability; deplete resources, clear-cut ecosystems, extinguish species, and degrade soils and water supplies.  We consume today and push the bills into the future.  This is the real meaning of the news that US national debt has now topped $20 trillion.

Falling per-capita farmland raises critical questions

Graph of per capita farmland arable land, global, 1950 to 2050
Per-capita arable land (cropland), world average, 1950 to 2050.

As populations continue rising, per-capita farmland area is falling.  In 1950, for each person in the world (about 2.5 billion back then) there was, on average, 0.46 hectares of cropland (“arable” land).  That is an area roughly equal to the in-bounds playing area of a US football field.  Today, per-capita cropland area is just 0.19 hectares.  By 2050, it will be lower still: 0.15 hectares—one-third the area in 1950.  We’ll soon be down to just a third of a football field each.

The graph above shows the average per-capita cropland area from 1950 to 2050.  The units are fractions of a hectare.

Humanity’s in a bind.  We’re becoming more numerous.  The UN predicts a global population of 9.8 billion by mid-century.  Moreover, we’re becoming richer.  Projected rates of economic growth—3 percent compounded annually, according to the World Bank—will cause the size of the global economy to nearly triple by 2050.  That enlarged, enriched population will want to consume more food.  It will want to consume more of its food in the form of meat rather than vegetables or grains.  It will be more prone to overeating and more demanding of processed foods and junk food.  And it will waste more of its food, because comfortable, well-fed people do that.  In addition, more food will be diverted to energy and fuel uses, including biofuels for air travel and ocean shipping.  Based on these factors, the UN projects that food production in 2050 will have to be 70 percent higher than in 2005 (see here or here).

Here’s the bind.  In order to deal with climate change, the world’s governments have committed to reducing GHG emissions by 30 percent by 2030—just over 12 years from now.  And reductions of 50 to 80 percent are needed by 2050.  How do we expand food supplies and reduce emissions?  Bringing new land into production (Amazon rainforest, for example) emits huge plumes of GHGs as soil carbon is released by tillage.  If we want to reduce emissions we cannot afford to continue releasing carbon stored in forests or grasslands.  So the alternative is to intensify production—produce more on the land we already have.  This usually requires more fertilizer.  But the most used and most critical fertilizer, nitrogen, is made from natural gas and is a major source of GHG emissions.  Globally, nitrogen (N) fertilizer use has doubled since the 1970s (see blog post here); Canadian farmers have doubled their N use since the 1990s.  Our commitments to downward-trending GHG emissions is already in conflict with upward trending nitrogen fertilizer usage.

In the face of monumental problems such as these it is best to just spend some time mulling our predicament.  We must resist the “rush to solutions.”  For now, let’s just consider some questions:
– Can we continue to waste 20 to 40 percent of our food?
– Can we burn food in cars and airliners and cruise ships?
– Should we increase livestock production by two-thirds in the next three decades (as the UN predicts), knowing that many livestock production systems inefficiently turn 5 to 10 Calories worth of grain into one Calorie of meat?
– Should we continue to make bad food out of good—producing millions of tonnes of nutritionally disfigured foods such as soft drinks, cocoa puffs, and potato chips?  (One quarter of US Calories now come from junk food.  See here.)
– Should we continue to foster a food industry that promotes over-eating and resulting health problems?

As our per-capita land base contracts, and as our atmospheric emission-space fills, can we afford these extravagances?  …these follies?  An adequate response to these problem will require re-imagining and restructuring of our food system–fundamental changes to food production and consumption.
