What really is global warming?

Answer 1

When we speak of global warming, we usually mean the rise in average global temperatures that began with the Industrial Revolution and has gathered pace since about the 1970s. Climate scientists say it is caused by rising greenhouse gas levels, substantially as a result of human activities.

A:

The theory that the planet is warming at an alarming rate.

Answer 2

• The earth is warming up because we are burning too much fossil fuel and cutting down forests all over the world.
• We burn fossil fuel in transport and factories, and to generate electricity.
• This means more carbon dioxide goes into the atmosphere.
• The normal carbon cycle can't cope with all the extra carbon.
• The atmosphere warms up, all over the world, globally.
• This global warming is causing climate change.

Answer 3

Global warming refers to the long-term increase in Earth's average surface temperature due to human activities, particularly the release of greenhouse gases such as carbon dioxide into the atmosphere. This leads to changes in the climate, causing rising sea levels, extreme weather events, and other environmental impacts.
