Crop damages are non-linear
Crops can tolerate heat up to a particular point, past that point the plant gets damaged then dies.
Climate change is affecting what we can grow and where, with implications we can't really predict.
If you live in N. America, food you eat is probably grown in the orange “major heat risk” strip in California's Central Valley. The heat threatens crops, farmworkers & our entire food system. This is our planet at 1.2 degrees of warming yet California is STILL approving new oil wells. #ClimateSky 🔌💡
Here in Canada, we source much of our food from the United States. Our imported produce is the bedrock of our diet.
What we grow ourselves is also heavily under threat due to climate change and a lack of workers willing to brave the heat and go out to harvest. It's deadly for livestock, too.
