    •The combined global land and ocean average surface temperature for May 2012 was 0.66°C (1.19°F) above the 20th century average of 14.8°C (58.6°F). This is the second warmest May since records began in 1880, behind only 2010.

    •The Northern Hemisphere land and ocean average surface temperature for May 2012 was the all-time warmest May on record, at 0.85°C (1.53°F) above average.

    •The globally-averaged land surface temperature for May 2012 was the all-time warmest May on record, at 1.21°C (2.18°F) above average.

    I don't know about its accuracy, but here it is! I question it as it is way outside of the satellite data.

    Since it was warmer in 2010, is that evidence of global cooling?

    In geological terms 125 years ain't even a drop in the bucket. What did the US do to cause global warming back in 1880?

    The term is climate change; it is unusually cool in NE Florida. The forecast of 30-40% chance of rain has been followed by heavy thunderstorms the last four days.

    It was a good amount cooler in 1880 of course...This is just the warmest of the years since that time. :)

    Second warmest if you "believe" the NOAA data since the medieval warm period of 1300. Really, I'm seriously not sure of that.:eusa_whistle: As there may of been a warmer May within a super nino somewhere in there, but well, to broad brush it. :eusa_liar:

    It has only been since the late 1800's that we have had enough weather stations worldwide to give a reasonable comparison of monthly records. Earlier than that, yearly, at best, is all that we can do.

    Here you can see why they chose 1880 to start world temperature comparisons. This is from the BEST study, and shows how the recording of temperature grew from a few small areas in 1800, to worldwide by 1880.

    RISS shown the 7th warmest May
    UAH shown the 4th

    It just doesn't match with the satellite data.

    It stinks!

    Look at the last 30 years of data, plot and slope the data, is the trend positive or negative?

    US? or humanity in general? If it was showing up in 1880, it was due to events further back. It takes time for effects to equilibrate throughout a system as complex and massive as our planetary environment. Humanity's impact on our environment is not new, it stretches back 8-10k years, when we first began large scale agricultural development. Our impact simply magnified tremendously when we began using massive amounts of long sequestered carbon substances as fuels.
