Farmers can put up with some bad weather, but climate change will make unusual events more likely.
20-30% of plant and animal species will be more likely to become extinct if the temperature rises by more than 1.5-2.5C.
There will be big effects on farming from droughts and floods.
The biggest effects will be seen first near the equator.
Just being near the equator makes it more difficult for countries to make economic progress.
Hotter conditions affect how crops grow.
Our agriculture is heavily reliant on grasses from the temperate regions.
Corn, wheat, rice and so on are all types of grass.
The tropics is a hard place to grow an industrial society.
The tropics will expand as the world warms, so the world will find it harder to grow those important crops.
