A long report in the LA Times reminds readers that climate change is not all about droughts and floods. It’s also about winter chill. Many fruit trees absolutely must have a certain number of cold days in the winter to prepare them for spring blossom and summer fruit. Those chill days are declining fast in California’s Central Valley.
“Climate change is not just about sea-level rise and polar bears,” said UC Davis researcher Eike Luedeling, lead author of the study. “It is about our food security. Climate change may make conditions less favorable to grow the crops we need to feed ourselves.”
Can’t argue with that. But are California’s fruit farmers likely to experiment, as the farmers of Kazakhstan have done, with planting different varieties, maybe even seedlings, to see whether any of these are better able to produce under different conditions? Somehow, I doubt it.
