Grain yields have increased thanks for pesticides, herbicides, selective breeding and mass agriculture improvements. And the misuse of said herbicides as dessicants (eg. Roundup). I don't know how hardy grain is specifically, but I was remembering the issue with apples in Ontario: https://www.ontario.ca/page/why-we-need-address-climate-change https://www.ontario.ca/page/why-we-need-address-climate-chan... March 2012 was so warm, apple trees bloomed early, but then lost 80% of their fruit because of a severe frost two months later 2012 wasn't the only year.
