Title : save the earth.

Hello there! Just want to let you people know that this is the time you have to save the earth. Everything is going to change in the coming years in a sense that the climate will be changing in the coming future. Global warming is serious now. Let us save the earth by saving the electricity in your home and recycle paper, plastic or tin if you can. By watching the live earth concert,i am now aware that we really need to do something about it. So let us do a part so that we can save the earth. We have a choice.

I have done a little bit of research of the future climate change that is Greenhouse gas concentrations in the atmosphere will increase during the next century unless greenhouse gas emissions decrease substantially from present levels. Increased greenhouse gas concentrations are likely to raise the Earth's average temperature, influence precipitation and some storm patterns as well as raise sea levels. The magnitude of these changes, however, is uncertain.

The average surface temperature of the Earth is likely to increase by 2.5 to 10.4°F (1.4-5.8°C) by the end of the 21st century, relative to 1990. This projected rate of warming is about two to ten times greater than the warming observed during the 20th century and may represent a warming rate unprecedented for at least the last 10,000 years.
Warming will not be evenly distributed around the globe:

Land areas will warm more than oceans in part due to water's ability to store heat.
High latitudes will warm more than low latitudes in part due to positive feedback effects from melting ice (as discussed above).
The northernmost regions of North America, and northern and central Asia, could warm substantially more than the global average. In contrast, projections suggest that the warming will be less than the global average in south Asia and southern South America.
The warming will differ by season with winters warming more than summers.
