In what ways has global warming changed our world? Rising sea levels, melting glaciers(冰川) are just a few examples. But did you know that global warming can also bring other changes?
Ending racial(种族的) differences
Global warming causes droughts and poor harvests. This can make people leave their homelands and move to other places. In just 125 years, there may be fewer people with dark skin or pale skin. More people will have brown-colored skin.
Making insects hungrier
When it is warmer, insects’ body temperatures go up along with the outside temperature. This is very different from humans, who can keep their body temperature at a certain level. Higher body temperatures can step up the insects metabolism(新陈代谢). This makes them hungrier, so they need to eat more. And this also makes insects bred(繁殖) more quickly．
Helping scientists find historic sites
Britain had a very dry and hot summer this year because of global warming. After the dry weather turned the country’s green landscape yellow, people noticed some unusual patterns in the middle of a field. That s because grass that grows above them has a different color and height from other grass. This helped people see the patterns. After studying these patterns, scientists found something old and a Roman farm.
