Most Common Explanations Against Global Warming

Global Warming Consequences: by US State, by Country, by College

This is just a natural variation of Earth. Humans are not the cause.
We are just coming off a mini-Ice Age and the Earth is just naturally going back to a normal more hot point.
There is no evidence that CO2 levels cause global warming.
CO2 pollutants by humans are only a very small percentage of the makeup of the atmosphere. 94% is water vapor by weight. Therefore humans are only interfering in a really small percentage of reality.
The Earth has had more hotter periods than the one we are currently experiencing now. For example, the medieval time period was much harder.
CO2 does not drive temperatures as is claimed. Trees actually breathe better with CO2.
Scientists have to create a problem to get money for research. Thousands of jobs depend on global warming, therefore a lot of scientists feel intimidated to feel global warming is a problem.
