Global warming since 1999

Climate change deniers like to claim there has been “no warming since 1998″ which was an especially warm year due to an intense El Nino.  Well that ain’t true.  Global warming has indeed continued, especially in the deep sea due to the prevalence of several La Nina events recently.

Here is how much the land ocean surface has warmed since 1998 (1999-2012, from NASA):

Most the warming is obviously in the Arctic, which is why Arctic sea ice is being lost so rapidly.
