What exactly is the kind of response you want?
Shannon posted a link to the Intergovernmental Panel on Climate Change:
http://www.ipcc.ch/pub/pub.htm
It was set up by the World Meteorological Org and the United Nations Environment PRogramme.
I can copy and paste some of the results of those leading scientists from over 130 countries and 2500+ scientific expert reviewers. But if you're really curious, and not just out to stir a flame war or trolling, then you'd go out there, read it, and educate yourself.
If you want a more condensed version read wikipedia:

Climate change and conservationism is a dear and important issue to a lot of people. And I don't think you should make up your mind just based on an improv forum or how people who believe it treat you. That's just childish.
Anyway, what the heck. Here, I'll copy and paste part of the wikipedia article for you. The results of the IPCC Feb 2007 study:
# Warming of the climate system is unequivocal
# Most of the observed increase in globally averaged temperatures since the mid-20th century is very likely (greater than 90% likely) due to the observed increase in anthropogenic (human) greenhouse gas concentrations
# Hotter temperatures and rises in sea level "would continue for centuries" no matter how much humans control their pollution.[9], although the likely amount of temperature and sea level rise varies greatly depending on the fossil intensity of human activity during the next century (pages 13 and 18)[10]
# The probability that this is caused by natural climatic processes alone is less than 5%
# World temperatures could rise by anything between 1.1 and 6.4°C (1.98 and 11.52°F) during the 21st century (table 3) and that:
* Sea levels will probably rise by 18 to 59 cm (7.08 to 23.22 in) [table 3]
* It is more than 90% certain that there will be frequent warm spells, heat waves and heavy rainfall
* It is more than 66% certain that there will be an increase in droughts, tropical cyclones and extreme high tides.
# Both past and future anthropogenic carbon dioxide emissions will continue to contribute to warming and sea level rise for more than a millennium.
# Global atmospheric concentrations of carbon dioxide, methane and nitrous oxide have increased markedly as a result of human activities since 1750 and now far exceed pre-industrial values over the last 650,000 years
