claim: But observations, such as those on our CO2 Coalition website, show that increased CO2 levels over the next century will cause modest and beneficial warming—perhaps as much as one degree Celsius ( 1.8 degrees Fahrenheit )
evidence: The Kyoto Protocol is an international treaty which extends the 1992 United Nations Framework Convention on Climate Change ( UNFCCC ) that commits state parties to reduce greenhouse gas emissions, based on the scientific consensus that ( part one ) global warming is occurring and ( part two ) it is extremely likely that human-made CO2 emissions have predominantly caused it.
