The Graphic Truth: Has climate change hurt or helped farmers?

Over the past half century, climate change has had an immense impact on the farmers who produce the food we eat. A new study by Cornell University shows that global warming has knocked 21 percent off of global agriculture productivity growth since 1965, equivalent to seven years of normal growth if humans had not polluted the planet. But not all countries have been affected in the same way. Farmers in warmer parts of the world have been hit hard as conditions grow more arid, but sub-polar regions in Canada or Siberia are now actually better for agriculture because they are not as cold as they used to be. Here we take a look at how climate has affected farming productivity growth around the world.
