Food shortages by 2040 caused by climate change? Another of those unverifiable predictions?We have a report of Food Shocks Due To Climate Change Likely By 2040 to be caused by climate change. Instead of being something that happens every 100 years, climate change supposedly will cause it to happen every 30 years. No gradually decreasing frequency of food shocks just a jump from 100 to 30 in 25 years. As usual, these claims assume no ability to adapt to whatever disaster is predicted and, in this one, it seems that we have to believe technology in the 21st century is identical to the early 20th, 18th or 17th. It also seems to ignore increasing food production rates. Future food scares seem to be climista constants. Just ignore the data and project far enough into the future that no one will remember you made it.
