Global wamring effects on animals

Global Warming affects cold seas and polar communitiesl: Polar bears are losing weight and getting less fit because the ice caps are breaking up and polar bears are finding it hard to catch food.

As average temperature increases, optimum habitat for many species will move higher up mountains or further towards the Poles.

Global Warming Effects!

Global warming has a big effect on sea levels. As the earths atmosphere heats up it cause ice caps to melt which will cause sea levels to begin to rise around the world. Global warming also has a huge effect on humans, animals and plants because if the tempeture keeps rising in the earths atmosphere it will cause significant worlwide climatic changes eg. Hurricanes have changed in frequency and strength, Heat waves more frequent and Warmer temperatures affect human health.

How to decrease global warming

Everybody can help to decrease global warming by 1.recycling - if people recycle they can stop the amount of tree's being cut down around the world. 2. walking instead of driving short distances.- if people stop driving short distances and walk instead they would stop the amount of methane gases being released into the atmosphere. 3. turning off all lights and other electrical equipment which you are not using.- this would decrease the amount of fossil fuels being burnt to supply elecricty.


If everyone does their part, there would be a significant change in global warming.

Global warming weather

Globalwarng has a huge effect on weather. eg. warming winds, hurricanes, increase of rain etc. Extreme weather will increase if we continue buring the amount of fossil fuels and not doing anything about global warming. Extreme weather will decrese population eg. tsunami will destroy buildings and kill many people, hurricanes will sweep through towns destroying buildings and homes of peoples and also lowering population.

Global warming causes

Man made causes- Global warming is mainly caused by man. The main problem caused by man is pollution, eg. burning fossil fuels which release methane gas into the earths atmosphere which then traps heat in the atmoshere.
Population is another problem assoiated with global warming because a rise in population in any country means that more food and more ways of transport. More transport means more methane gases are produced into the envirement because more fossil fuels are burnt.

Global warming 101

This video shows what global warming is doing to our planet. I got this video from youtube.

An Inconvenient Truth

This is a short clip from the movie The Inconvenient Truth which shows what we can do to help stop global warming. I got this image from Google Video
