Global temperatures are rising, but why is it so hot?

The Earth’s average temperature has risen by 1.1 degrees Celsius since the late 19th century, and is expected to rise by another 1.5 degrees by the end of the century. This increase in temperature has led to a number of negative consequences for both humans and animals, including heat waves, wildfires and droughts.

There are a number of reasons for this increase in global temperatures. The first reason is that there is more carbon dioxide in the atmosphere than ever before due to human activity. The second reason is that there are fewer trees than ever before, which means less carbon dioxide is being absorbed from the atmosphere.
