I meant the opposite. I don't believe that "1°C warming" is mild.

Just FYI, but that "about 1.0o F" that Google pulls is from an archived website from the Clinton white house. No Clinton has been President for over 20 years.

The 1°C increase that your link says has happened would indicate an approximately 0.8°F increase since those Clinton years. Nearly a doubling in 20-30 years from the baseline increase over the previous 100 years.
