Global Warming

Global Warming

The planet is getting hotter because we are burning fossil fuels and adding other green house gases to the atmosphere.

Outgoing radiation is decreasing owing to increasing greenhouse gases in the atmosphere known as the Earth's energy imbalance. This means that more of the sun's radiated heat is being trapped rather than radiated away so the planet gets warmer and warmer.

Warmer air holds more water hence heavier rainfall, more storms and more flooding.  

Warmer air makes the oceans warmer and glaciers melt at the poles and high mountains so sea level rise.

Warmer air dries out the land so forest fire are more likely and more damaging and more land is turned into deserts.

Warmer air changes agriculture dries out the land so forest fire are more likely and more damaging.

The climate is changing and people, wildlife and plants suffer and die.
