Draft:Why climate change is a problem

TODO: mention

• increased rates of heat stroke in countries that are already hot - estimated numbers of deaths
• lower food production as hot places become too hot to grow crops; then again, how does that compare to the cold regions that would then become warm enough to grow crops?
• climate refugees
• Global warming refers to the increased average temperature around the world. 1 or 2 degrees increase doesn't seem like much, but it also comes with more fluctuations of temperature - more extreme hot days, more extreme cold days, and more storms. The whole shebang is referred to as climate change.
