 What is global warming?
Global warming is the term used to describe the rising of the average temperature on Earth. It has to do with the overall climate of the Earth rather than the weather on any given day.
Why is global warming important?
Here are few of the things that scientists think may happen as the temperature rises. Some of them are still taking place:
- Glaciers melting - Many glaciers are already melting and getting smaller throughout the world. If the temperature increases they will continue to melt .
- Ocean levels - As the glaciers melt, ocean levels will rise. This could cause flooding in cities located near the coast.
- Migration of animals - Animals will migrate to cooler spots as their old habitats get too warm. This could upset the food chain and put some species in danger of extinction.
- Extreme weather - Some scientists think that warming will fuel more powerful hurricanes as well as more droughts and flooding in different areas of the world.
- Change in ecosystems – The characteristic plants of cold weather such as the tundra will get smaller, while deserts will continue to get larger.
