Climate Change Has Cut Global Food Productivity By 20%

A new study has found that climate change has caused agricultural productivity to fall by 20% over the last 60 years. Farmers are now growing significantly less food than they would be if the weather was the same as it was in 1961. The researchers say that the drop in productivity is due to changing weather patterns, flooding and droughts. Unexpected shifts in weather make it harder for farmers to plan productive strategies and maximize their harvest. In regions such as Latin America, the Caribbean and Africa, productivity has dropped by almost a third. Our study finds that [man-made] climate change is already having a disproportionate impact on poorer countries that depend primarily on agriculture, Ariel Ortiz-Bobea, economist at Cornell University
