“Nine of the 10 warmest years since 1880 have occurred since the year 2000,” reports NASA’s Goddard Institute for Space Studies. The first years of the new millennium experienced “sustained higher temperatures than in any decade during the 20th century.”
Goddard, which monitors global surface temperatures, compiled the findings into an animation showing global temperature trends since 1885.
The animated map charts differences from the average temperature recorded during a baseline period of 1951-1980. Dark Red zones are two degrees Celsius warmer than the baseline; dark blue are two degrees colder. You can download a copy of the animation here.
The average incremental change is not great — less than a Celsius degree in total — but the upward trend is, shall we say, hard to deny:
