Cars and factories produce more carbon dioxide (CO2) every year.
The sun’s rays warm the Earth, keeping everything from freezing. But carbon dioxide (CO2) from cars and factories and homes slows down or stops the heat from the rays escaping back into space. So the Earth warms up. Too much heat causes temperatures to rise. Global warming is the name for this increase in the temperature of the Earth’s atmosphere and its oceans over time. Some people believe the change to the Earth’s climate is permanent.
Between 1880 and 2012, the average temperature of the Earth increased by almost 1° Celsius. That small change it has caused our oceans to heat up, snow and ice to melt, and sea levels to rise. It has also affected the weather.
