Global Warming in a Nutshell

 

Climate Scientists are agreed that global warming is a serious problem that must be addressed urgently. Polls show that only about 60% of ordinary people are convinced that global warming is man made.

1. The Earth's Temperature
The temperature of Planet Earth is maintained by two sources, heat from the sun, and a tiny amount of heat from the Earth's core.

2. The Greenhouse Effect
Without the atmosphere, Earth would be 33°C colder than it is because the sun's heat is retained by the gases in the atmosphere, which act as a kind of duvet.

3. Life on Earth
Life is adapted to a narrow global temperature range, which we alter at our peril.

4. System
The atmosphere is a system that is so complex that it can only be studied by computer models which can make the various factors interact. All these models show that we face serious problems.
