Recently, there was the usual wailing and gnashing of teeth in the media over the threat of “climate change” as outlined in Ramankutty et al. published on January 6th, in Nature and touted by press release. An excerpt from that press release reads:
At a time when global warming is projected to produce more extreme weather, the study provides the most comprehensive look yet at the influence of such events on crop area, yields and production around the world.
“We have always known that extreme weather causes crop production losses,” said senior author Navin Ramankutty of UBC’s Liu Institute for Global Issues and the Institute for Resources, Environment and Sustainability. “But until now we did not know exactly how much global production was lost to such extreme weather events, and how they varied by different regions of the world.”
The researchers analyzed national production data from the UN’s Food and Agriculture Organization for 16 cereals in 177 countries. They also examined 2,800 international weather disasters from 1964 to 2007.
Findings indicated that cereal harvests decreased by nine per cent to 10 per cent on average due to droughts and extreme heat. The impact from droughts also grew larger in more recent years.
However, the reality of global agricultural production just isn’t cooperating with Ramankutty’s views. Via the GWPF:
