The term “ global warming hiatus” is a bit of a misnomer. It refers to a period of slower surface warming in the wake of the 1997-98 super El Niño compared to the previous decades. However, make no mistake, the globe’s average temperature has still risen over that period (including record heat in 2014 .. http://www.climatecentral.org/news/record-2014-hottest-year-18502 ) and temperatures now are the hottest they’ve been since recordkeeping began in the 1880s. So let’s call it what it really is: a slowdown, not a disappearance of global warming.
The new findings show that even the concept of the slowdown could be overstated.
“There is no slowdown in global warming,” Russell Vose, the head of the climate science division at the National Centers for Environmental Information .. https://www.ncei.noaa.gov/ (NCEI), said. “Or stated differently, the trend over the past decade and half is in line with the trend since 1950.”
Vose helped author the new study, which uses new information about how data is collected at sea to reanalyze surface temperature records. The new analysis essentially doubles the rate of temperature rise since 1998. That puts it more in line with warming trends since the 1950s, though some researchers said there were still some periods of faster warming on record since the 1950s.
Of course this discussion is all centered around changes in hundredths of degrees.
“The fact that such small changes to the analysis make the difference between a hiatus or not merely underlines how fragile a concept it was in the first place,” Gavin Schmidt .. https://twitter.com/ClimateofGavin , the head of the NASA Goddard Institute for Space Studies, said.
The study was inspired by some new metadata, the data behind the data, that provided clues that scientists weren’t properly accounting for certain types of measurements. Specifically, there have been a proliferation of buoys over the past 40 years and the survival of an antiquated measurement technique used by ships.
Buoys have increased global coverage of the oceans by up to 15 percent since the 1970s, but they have a known cold bias compared to measurements taken from ships.
Another more quirky feature of how global temperature is determined comes from ships. Prior to World War II, the most common way to measure ocean temperatures was dropping a bucket over the side of a ship and scooping up some seawater and dunking a thermometer in.

The process was thought to have pretty much stopped as ships moved to more modern measurements by taking temperatures directly in the water right by their engine intake valves. But the new metadata show that the bucket method is still alive and well and the new findings account for that, something previous analyses haven’t done.
The final piece of the puzzle was the Arctic, which is historically hard to measure given the harsh conditions but is incredibly important to the world’s climate. It also happens to be warming twice as fast .. http://www.climatecentral.org/news/arctic-sea-hits-record-low-winter-peak-18795 .. as the rest of the globe.
Vose said their new analysis includes updates based on all three of these areas and the result shows warming hasn’t really slowed.
“It is clear that Karl et al., have put a lot of careful work into updating these global products,” Lisa Goddard .. http://iri.columbia.edu/contact/staff-directory/lisa-goddard/ , director of the International Research Institute for Climate and Society, said. “The impact on our estimates of the trends, especially over the oceans, does seem noteworthy.”
However, Goddard said the results don’t fully show the slowdown has disappeared when comparing the past 15 years to the decades preceding that period and that understanding the natural fluctuations in climate on a year-to-year .. http://iri.columbia.edu/contact/staff-directory/lisa-goddard/ .. (or even decade-to-decade) basis provides important context to the warming trends driven by carbon dioxide.
Peter Stott .. http://www.metoffice.gov.uk/research/people/peter-stott , the head of climate monitoring at the U.K. Met Office, agreed, noting in an email that, “The slowdown hasn’t gone away, however, the results of this study still show the warming trend over the past 15 years has been slower than previous 15 year periods.
“My view on this is that the research needs to broaden out to have more of a focus on variability more generally so that a) we can predict the next few years better b) we can refine our estimates of the sensitivity of the climate system to increases in greenhouse gas concentrations.”
“The fact that Intergovernmental Panel on Climate Change said that there’s this hiatus inspired a whole lot of studies,” Vose said. “Here’s why that’s good: a lot of those studies are correct. There probably would’ve been additional warming if those factors hadn’t taken place.”
NCEI is a member of the Fab Four global temperature analysts — the other three being NASA, the U.K. Met Office and the Japan Meteorological Agency — and each uses slightly different techniques to analyze the data but they’re all in general agreement that the planet is warming.
Stott said the Met Office is also refining its estimate of the global temperature and that the new analysis is within the range of uncertainty the Met Office agency includes in its analysis.

We're way past the point of pretending the world isn't warming, so the question really should be why the major parties are so silent on their climate policies during an election campaign, writes Greg Jericho.
One aspect of having an election during winter is that even though temperature records are being broken, climate change is largely out of voters' minds.
[ .. couple of interactives and more ..]
Since 1880 the record average temperatures for January-April has been set 17 times (including 1880). The average increase in the record has been .07C, and there has never been an increase in the record of more than 0.2C. And yet in the first four months of this year the average temperature was 0.38C above the previous best - an increase 5.3 times greater than the average increase: Embed: January-April record temperature averages
It would be like someone coming along and breaking the individual test cricket innings record by 124 runs rather than the average improvement of 24 runs.
The temperature in April also meant that the previous 12 months was the warmest 12 month period on record - beating the previous best which was set in March, which beat the previous best which was set in February, which beat the previous best which was set in January, which beat the...
It's all getting a bit monotonous, and makes one almost pine for the days when you could say "the world hasn't warmed since...".
So clear is the evidence now on temperatures rising, that to say that the world isn't warming requires a level of ignorance so brutally departed from reality that the polite thing would be to at least include mentions of dragons, white walkers and the kingdom of Westeros in your fantasy tale to give it some interest.
Climate change deniers still futilely hold to the view that the world hasn't warmed since 1998 and yet had we in 1998 thought to forecast ahead to 2016 based on what had occurred over the previous 30 years, we still would have undersold just how much the world would warm.
