Global Warming

this topic is really popular, but i wonder how many people take this problem seriously...? every year, the tempeture is getting higher and higher than before, so it is clear that global warming has become worse. Actually, i often fell guilty when i turn the air conditioner on lol but i finally turn it on because i can not bear the hotness. I think many people is like me, I mean even people recognize global warming but many people do not take action. Although it is diffecult to change every convinient system in this society, but I think we have to do something. I want to know what do other people think about this problem. What do you think??
