Global warming is the increase in the average temperature of the Earth's near-surface air and oceans since the mid-20th century and its projected continuation.
It happens when greenhouse gases, such as carbon dioxide, water vapor, nitrous oxide and methane, traps heat and light from the sun into the earth's atmosphere, which makes the temperature go up but the greenhouse
gases are not really the main cause of global warming. The main cause of global warming is orbital eccentricities of Earth and variations in the Sun's output.

Global warming is harms the earth. It doesn't only harm the earth but it also harms us, the animals, and the environment.
If global warming worsens, it will make a chain reaction. A chain reaction is a break in the food chain and one of the examples is when the glaciers melt, it will flood and too much water might make the plants die and without
plants some animals can't survive and when there's no animals, people won't have anything on their plates.

Sounds worst doesn't it? But we can reduce it by going green!. Doing little steps like these can also make a big difference!.
