Food prices higher due to warmer climate

But wait, climate change doesn't really exist so there must be a mistake.

Global warming has already harmed the world's food production and has driven up food prices by as much as 20% over recent decades, new research has revealed.

The drop in the productivity of crop plants around the world was not caused by changes in rainfall but was because higher temperatures can cause dehydration, prevent pollination and lead to slowed photosynthesis.

Lester Brown, president of the Earth Policy Institute, Washington DC, said the findings indicate a turning point: "Agriculture as it exists today evolved over 11,000 years of reasonably stable climate, but that climate system is no more." Adaptation is difficult because our knowledge of the future is not strong enough to drive new investments, he said, "so we just keep going, hoping for the best."
