Spring 2014 Was the Hottest on Record Globally

Think Progress: “The Japan Meteorological Agency (JMA) reported Monday that March-May was the hottest in more than 120 years of record-keeping. It was also the hottest May on record. This is especially noteworthy because we’re still waiting for the start of El Niño.”

“It seems all but certain more records will be broken in the coming months, as global warming combines with an emerging El Niño.”

    Yeah but it was cold in the eastern U.S. this winter, so…liberal hoax!

    GLOBAL WARMING IS A FACT!
    We MUST:
    -ban oil, gas, coal and nuclear
    -safe wind and solar only
    -end private use of cars: public transportation for all
    -end un-needed air travel. Vacation at home!
    This warming is a planetary RED ALERT.
    We must take action NOW. If Republicans have their heads stuck in the ground (or somewhere else!) the President MUST institute these changes by EXECUTIVE ORDER!
    THE VERY LIFE OF MOTHER EARTH DEPENDS ON DRASTIC ACTION RIGHT NOW!

      hyperbolic bait
      oil, coal and,gas, need to be transitioned away from, but a ban is neither practical nor being advocated by anyone. Closest thing to that even being contemplated would be bans on new power plants from these sources. Nuclear is under debate from people of all political stripes.

      Wind and Solar are increasing rapidly, and the most energy dense out of the new renewable options. but we have room for plenty of other renewabes in the picture

      no one is talking about banning cars, but a transition to ones that don’t burn the juice of dead things is goes for everyone’s health as well as the climate, and if we can build some more mass transit to help with our clogged roadways, and help the climate at the same time why not?

      no-one is talking about ending air travel either, but targeted biomass to run ariplanes would be a very good idea.

      and no none of things you mention are going to be done by executive order.
      and no the life of ” mother earth” is not in doubt, It is the lives, of humans, the damage to our infrastructure, and the complex ecosystems we depend on that is at risk.

        The computer models haven’t done so well with “complex ecosystems” have they?

        • moderatesunite

          direct measurement like the ones above show unquestionable warming that cannot be explained by any natural cause but are explained perfectly by human GHG emissions.
          The models have predicted the changes pretty well actually. But direct measurements over the last several decades confirm what is happening without resorting to any models

    Cue the hate and bile from conservatives whenever someone brings up the topic of global warming. Remember the Conservative Creed: Science is a matter of opinion, and the views of non-scientists and the uninformed are just as valid as those of experts in the field.

      NCDC USHCN in 1999 showed a nice sine wave in temperatures from 1895 to 1999 but no warming trend if you looked at peak to peak. The data was regarded as the best in the world with relatively stable stations (though as Anthony Watts showed increasingly poorly sited) and with adjustments for urbanization developed by NCDC chief Tom Karl, which offset some of this local contamination. Hansen in 1999 said after the super El Nino of 1997/98 (which was 1.1F cooler than 1934 that there was a lot of year to year variability but little long term trend with the 1930s clearly the warmest decade and 1934 the warmest year. Hansen posted a note on GISS that the US was only 1.6% of the world and local variances are always possible (even though it was known as GLOBAL warming).

      This produced a dilemma for the modelers and policy makers as the global data set which unlike the US had no UHI adjustment because NCDC did not have the metadata (precise local siting info) to use the same adjustment. NCDC was pressured to make the US data consistent – and so in 2008 they removed the urbanization adjustment and substituted a new algorithm to ‘detect previously undisclosed inhomegeneities’ (station moves for example). Although this new algorithm might catch a few stations where moves had not been documented, the removal of the UHI adjustment and a final new step called homogenization resulted in a significant change so that 1998 suddenly went from 1.1F colder than 1934 to almost 0.0 to 0.1F warmer than 1934.

      The change was about 1.3F with early cooling and late warming.

      There have been a few more iterations for the US and global data – each increasing the computed warming. This March after a very cold winter had NCDC sweating, a new version of the US state data displayed at Climate at a glance took place.

      See an example of what they did for one state – Maine. In 2012, I downloaded the annual data and it showed little change over time. In fact as of 2013, the NCDC Maine data showed a 0.03F/decade cooling since 1895.

      After March, the new state data showed a 0.23./decade warming with a cooling of the early 1900s by up to 5F.
