Krugman looks for an explanation of rising food prices which are leading to political unrest in poor countries and links declining food production to weather factors. 2010 was one of the warmest years in history. Rising sea temperatures has caused flooding in some parts of the world and Russian wheat production declined as result of high temperatures and draught. Temperatures in Moscow reached 100 degrees for the first time in history.
Krugman doesn't expect the usual suspects to buy into his argument but he believes that we are just seeing the beginning of the impact of global warming on weather patterns.
