intro

What i know about global warming is that global warming has been the subject of much debates since 1990. Gl0bal warming refers to the rise of globally average surface temperature. It is caused from human activity also the degree to which variations in global climite can be attributed to human made causes will undoubtly be studied and argued about for years to come. Many scientists express concern that the measured increases in global temperature are not natural cyclic fluctuations, but rather reflect human alteration of the climite.In effect, human burning of fossil fuels such as coal, gas, and oil well has added a vast amount of carbon dioxoide to the atmospere, causeing an intensification of the green house effect. The green house gases trap up heat near the earths surface. As concentrations of green house gases in the atmoshere increase, more and ,more heat is traped near the surface, warming the global climite.
-How is the world changing?
-Can we do something about global warming?
-What will happen if we dont act now bout the global warming?
The reason why i choose this suject was because its happening right now.We are getting alot of climite changes in our world. The reasons why we get hurricans is cause global warming.Also it interest me because the warming can cause sea levels raise.
