Effects of Global Warming

In the 1980’s scientists began to get worried that the earth was getting ever hotter. After conducting research, these scientists concluded that:
The average temperature of the earth had increased by 1° F (O.6°C). The level had risen by 10-25cm around the world. There is a strong relationship between the increase in world temperatures and the amount of greenhouse gases present in the atmosphere. Human activities increase the amount of these greenhouse gases. As we can see, even small changes in world temperature could set in motion large changes; these changes, due to global warming, will not be felt equally around the world, their affects will differ, from region to region. So the effects of global warming will be on: a change in the world’s climate; sea levels rising; a reduction in water supplies; a change in the world’s agricultural systems; changes of the world’s natural areas (for example cold areas will decrease) and an increase in disease.
