The Science and Politics of Climate Change -- Truman State University

The video summarizes the evidence for man made and naturally occurring climate change. Some of the data discussed include the facts that:

C02 levels have increased by around 50% since the 1950s.
Carbon Dioxide is 0.04% of Earth’s atmosphere.
Natural disasters have not increased in recent years.
Lack of C02 is a limiting factor in plant growth.
Global average surface temperatures may have increased by around 0.6 C (1.2 F) since 1880. Many measurements are uncertain.
Computer models predict further temperature increases in the future, but the models have been unreliable to date.
