Maybe farmers are "in on it" too.

How Alberta’s farmers are adapting to the uncertainty around climate change
Climate change doesn’t just mean warmer weather – it means unpredictability

Lynn Jacobson grows oilseeds, wheat, pulses (chickpeas, lentils and beans) and alfalfa on his 1,500 acres at Enchant, about 80 kilometres northeast of Lethbridge. A fourth generation farmer, a director with the newly created Alberta Wheat Commission and the president of Wild Rose Agricultural Producers, Jacobson is also exploring alfalfa seed and seed canola production. And like most farmers in the province, to do this he has to adapt to the effects of climate change.
Jacobson has little doubt it will change the way he works his fields. Already, because an increasing number of frost-free days are creating an extended growing season, he’s seen colleagues decide to grow different varieties of barley, wheat or canola. As Jacobson says, “It’s jokingly been said by some people that we’ll eventually become the grape producers of America.” But is climate change good or bad for Alberta’s farmers? And can they adapt to what appears to be a new normal?
On one hand, climate change might be good in some ways. After all, a warmer climate means longer and more growing days, which means more and better crop yields. The data bears that out to a certain degree, too. “Scientists at the University of Alberta have documented how the climate has changed over the past 100 years,” says Tom Goddard, senior policy advisor with the Environment and Stewardship division at Alberta Agriculture. “There has been a warming trend and we’ve seen more growing days in the province and slightly different moisture patterns.”
One of the ways this is measured is through the boundary for corn heat units, which measures where corn can be grown in the province. The northern boundary for these units has moved up a couple hundred kilometres since the 1910s, and it’s advanced about 50 kilometres since the 1940s. And that changing climate is allowing Alberta farmers to grow crops they couldn’t before.
