For former Vice President Al Gore, a new report that the Earth is hotter than ever — and that humans are to blame — has only confirmed what he has long said about global warming and the need to protect the environment.

“The Earth has a fever and just like when your child has a fever, maybe that’s a warning of something seriously wrong,” Gore said on “Good Morning America” today.

On Thursday, the National Academy of Sciences reported that the Earth’s temperature is at a 2000-year high and that “human activities are responsible for much of the recent warming.” The panel’s 155-page report said average global surface temperatures in the Northern Hemisphere rose about 1 degree during the 20th century.
