Remember how despite all of our vehicle exhaust and carbon emissions, we thought that global warming mightr just be a natural, cyclical shift in world temperature?

Well, the U.N. thinks that's bullsh**.

According to a report from the U.N. International Panel on Climate Change, climate scientists are 95 percent positive that humans are responsible for at least "half the observed increase in global average surface temperature since the 1950s."

This is an increase from 90 percent confidence in 2007 and just 66 percent in 2001, CNN reports.

The report also described an "unprecedented" increase in atmospheric carbon dioxide and predicted an increase of 3.7 degrees Celsius in global average surface temperature by 2100.

Whoops.
