If the Earth warmed as much as models say, the increase in Canada’s arable land would be an area two times the size of Quebec

“WHY CAN’T AL GORE be right?” asked my friend as we suffered another bitter Canadian winter.

Intolerable Januaries aside, global warming alarmists suggest we should be happy if global warming doesn’t occur. But that may not be the case, especially for Canadians.

Lee Harding.

A recent scientific analysis says that if climate models are correct, Canada could claim enormous amounts of new cropland before the end of the century. The implications are transformational, not only for the millions of square kilometres that could grow crops for the first time, but also for the direction of scientific research and government policy.

In May 2018, published a study entitled Northward shift of the agricultural climate zone under 21st– century global climate changeIt represented the collaborative work of six academics, including some from Newfoundland’s Memorial University.

The idea was to use models to anticipate what new lands could support crops due to climate change increasing the number of growing degree days (GDD). This represents the degrees Celsius above a base temperature (+5C for most crops) for each day within the frost-free growing season.

The GDD required by small cereals such as oats and barley was the threshold to map out the future frontiers of agricultural land. Averages were taken for seven climate models to mark out a map of what areas, on average, passed, met or surpassed the base GDD by 2099.

The results are, well, Earth-changing. Worldwide, just one-quarter of boreal areas now grow crops but, by the end of the century, it could look more like three-quarters. In this scenario, the reach of arable land could extend north another 400 to 600 kilometres in Russia, Finland and western Asia; 900 kilometres in Alberta; and 1,200 kilometres in eastern Siberia. This means an additional 10 million square kilometres could turn to farmland, with 5.1 million of them in Russia and 3.1 million in Canada.

The authors also predict “transformational” effects on local land use in Finland, Sweden and Kyrgyzstan. Cropland north of the 70thparallel could become a reality.

But the idea of farming far above the Arctic Circle might be far-fetched. Two peer-reviewed studies released in 2017 suggest the models have it wrong when it comes to the effects of greenhouse gases on temperatures.

John Christy and Richard McNider’s Satellite Bulk Tropospheric Temperatures as a Metric for Climate Sensitivity, published in the Asia-Pacific Journal of Atmospheric Sciences, demonstrated that global warming since 1979 was only half of what models suggested it should be.

Similarly, Nature Geoscience published Causes of differences in model and satellite tropospheric warming ratesto show that the post-2000 global warming predicted by climate models just wasn’t there.

Together, these studies challenge Canada’s prevailing perception of climate change and our approach to tackling it.

The science is neither as settled in its assessment nor as cataclysmic in its implications as many Canadians have been led to believe. Policy-makers and researchers have been too narrow in their focus on predicting climate change’s effects and its emphasis on prevention of those effects by limiting fossil fuels.

Billions of dollars spent on solar and wind energy, carbon taxation, and regulatory burdens on the production, transportation, and consumption of fossil fuels slow economic growth far more than world temperatures.

If Canada stopped all industry, had zero agriculture, produced no oil and no fires ever burned, 98.4 per cent of annual global greenhouse gas emissions would still be there. Yet if the globe warmed as much as the climate models suggest, the increase in Canadian arable land would be an area two times the size of Quebec.

So why does Canada look at climate change with fear and trepidation instead of hope and preparation?

The study on the northward shift says if northern regions like Canada want to be ready, there’s work to be done. Seasonal precipitation could be less than ideal in many areas, so winter water storage, summer irrigation and further development of drought-adapted plants will be necessary to seize the opportunities in many areas.

By contrast, on both Atlantic and Pacific coasts, Canada’s boreal regions will get more rain during the growing season than they currently do. This is generally helpful, but it will require more measures to control erosion and drainage.

If climate change does wipe out agricultural lands in some places, it will make land conversions and food security more important than ever. In this regard, Newfoundland and Labrador provided the study’s sole example of a government “pursuing a food security policy that includes expansion of agriculture on its territory, currently mainly covered by boreal forests.” In 2017, the province announced a five-year plan to double its farmland and increase its food security by at least 20 per cent.

Commentator Rex Murphy once quipped, “Vegetables require two things: soil and sunshine and Newfoundland has neither!” Yet Newfoundland expects a brighter future and is ready to pursue practical changes to get there.

Hopefully, the rest of Canada will soon follow.

  1. I tend to agree with David. There are models out there that just show wild swings as the prevailing winds cycle into big loops. One day 30, next -3…and that is already happening. We may get some warmth up there, but it’s kinda hard living with killing frosts 6 months of the year.

    Wow, this is wonderful news! We may be able to grow oats and barley in Inuvik sometime in the future, if things keep warming up. Let’s just go out and burn a few tonnes of coal and accelerate the damn process. Amazing that this study has been ignored up to this point, while the thousands of other scientific articles, vetted by credited journals and research institutions, documenting the ill-effects of human-caused climate change, have dictated our govts climate change policy. Something is definitely wrong here. Yup, we need to change course.

    For those of you who think climate change could be beneficial, I suggest that you take a stroll through the half-burned-down Sequoia national forest in CA, like I did the other day.

    Way to go David.!!!
    This article reeks of right wing /money men thinking.Any fool who thinks that world wide arrable land would increase needs a breath of fresh air.As ocean levels rise we (you know ! the world ) lose twice as much arable land as we gain. Say goodbye to Bangladesh and most of the worlds great cities and cultures.All of the great lowlands will be flooded and thousands of wild SPECIES will be lost. Thats OK is it Lee ?.The poentials for ocean rise are startleing .Up to 60 meters (plus or minus ).That would be most of the coast of Turtle island .Much of Quebec ,All of Florida .Of course we (the World )will still have 8 billion people and where will they go ????HERE.Say goodbye to CANADA EH ????
    To think that global warming could be a good thing is just plain stupid.Try joining another think tank.This one seems to be addling your thought process.

    I have 2 major problems with this assessment of the consequences of global warming.

    First, it is generated by a “think tank” headquartered in, and, presumably speaking for, the fossil fuel producing provinces of western Canada. The “give away” was the reference to “global warming alarmists”.

    Second, to conclude that anyone “wins” in a future characterized by the unpredictability and chaos wrought by global warming is intellectually dishonest. Having just witnessed first hand one of the principal consequences of a warming boreal region in the wildfire that captured our attention during the last few days, we should treat this assessment as the piece of propagandandist drivel that it is.
