What is global warming

What is global warming?

Global warming is the process when the earth heats up, and the temperature rises. This happens when there is an increase in the production of gases like carbon dioxide, water vapour, nitrous oxide, and methane, which are known as green house gases. These green house gases trap heat and light from the sun in the earth’s atmosphere, and this in turn, increases the temperature, and causes global warming .did you know? That since the beginning of the 20^th century, the average temperature of the earth has risen by 0.8 degree Celsius? Global warming hurts people, animals and plants. In fact many cannot take the change, so they die out.

Average Temperature

Despite the enormous variation in climates and regional temperature around the world, scientists use an average temperature from the entire surface of the earth to measure atmospheric changes as a whole. The overall average temperature of the earth has been risen over the past century. The average temperature of the earth today is about 15 degrees, while during the ice Ages of the past, it has gone as low as 11 degree Celsius.
