What is climate change?




In class, we've been studying weather and climate change.  
When scientists talk about global climate change, they're talking about the global climate and a pattern of change that's happening over many years. One of the most important trends that scientists look at is the average temperature of the Earth, which has been increasing for many years. This is called global warming.




Rising global temperatures lead to other changes around the world, such as stronger hurricanes, melting glaciers, and the loss of wildlife habitats. That's because the Earth's air, water, and land are all related to one another and to the climate. This means a change in one place can lead to other changes somewhere else. For example, when air temperatures rise, the oceans absorb more heat from the atmosphere and become warmer. Warmer oceans, in turn, can cause stronger storms.

This diagram shows how global warming can lead to a lot of changes.

This diagram shows how the Earth's atmosphere, climate, oceans, snow and ice, and ecosystems are all connected, which means extra greenhouse gases in the atmosphere lead to many other changes.
Scientists around the world agree that today's global climate change is mainly caused by people's activities.
