Is Global Warming Caused by man?

Scientists have evidence such as pollution and man-made green house gases have started tearing away the atmosphere. Natural green house gases have less water vapor and harmful effects on the environment.

One natural cause of global warming is the emission of methane from the artic tundra and wetlands.
