What is global warming?
![Page 4: Global warming explained](https://reader035.fdocuments.in/reader035/viewer/2022062510/5454c23faf79590c338b52bb/html5/thumbnails/4.jpg)
GLOBAL WARMING is the increase of the
Earth’s average surface temperature due to a build-up of greenhouse gases in the atmosphere.
CLIMATE CHANGE is a broader term that
refers to long-term changes in climate, including average temperature and precipitation.

The Sun’s energy passes through the car’s windshield.
This energy (heat) is trapped inside the car and cannot pass back through the windshield, causing the inside of the car to warm up.
