Extreme weather, species becoming extinct and islands disappearing - climate change is serious for both humans and the nature around us. What exactly is global warming, and why is this happening now?
What is global warming?
Global warming means that the air in the atmosphere, which is a gas layer around the earth, is becoming warmer. This affects the whole planet, and every living being on the planet. In 4.5 million years, our planet has changed a lot. There have been both ice ages and warmer periods. The difference now is that this change is happening very quickly. Since 1880 the atmosphere has become about 0.8°C warmer. Before the end of the 2000s, temperatures may have risen by as much as 2-4 °C.
⬅ Many of the world’s largest rivers are about to dry up due to climate change, such as in Australia.
