Presentation about Global Warming

TRANSCRIPT

Global warming is when the earth heats up (the temperature rises). It happens when greenhouse gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earth’s atmosphere, which increases the temperature.

Global warming is affecting many parts of the world.

Global warming makes the sea rise, and when the sea rises, the water covers many low land islands.

This is a big problem for many plants, animals, and people on islands.
