In June 2015, NOAA researchers led by Thomas Karl published a paper in the journal Science comparing the new and previous NOAA sea surface temperature datasets, finding that the rate of global warming since 2000 had been underestimated and there was no so - called «hiatus» in warming in the first fifteen years of the 21st century.

The deceleration in rising temperatures during this 15 - year period is sometimes referred to as a «pause» or «hiatus» in global warming, and has raised questions about why the rate of surface warming on Earth has been markedly slower than in previous decades.

And it's the year in which any credible sign of a pause or «hiatus» in the warming of Earth's surface through present day was thoroughly refuted.

«It has been claimed that the early - 2000s global warming slowdown or hiatus, characterized by a reduced rate of global surface warming, has been overstated, lacks sound scientific basis, or is unsupported by observations.

Roemmich said the study illustrates that the hiatus in warming of the sea surface and the lower atmosphere is not representative of the steady, continuing heat gain by the climate system.

a significant number of climate scientists acknowledge the hiatus in surface warming, though they feel confident it can be explained; 2.

The net effect of these anomalous winds is a cooling in the 2012 global average surface air temperature of 0.1 — 0.2 °C, which can account for much of the hiatus in surface warming observed since 2001.

http://climate.nasa.gov/news/1141/: «Norman Loeb, an atmospheric scientist at NASA's Langley Research Center, recently gave a talk on the «global warming hiatus,» a slowdown in the rise of the global mean surface air temperature.

They relate the current hiatus period at the surface and a deeper penetration of the warming into the ocean with changes in the trade winds on the subtropical Pacific (intensification).

The warm sea surface temperatures in the gyres, during hiatus decades, indicate convergence of near - surface currents and strong downwelling of heat.

The natural variability «flip - side» to these hiatus decades, are periods where there is greater - than - average surface warming (see inset in Figure 2).

The press release from NOAA included this statement from Karl: «Adding in the last two years of global surface temperature data and other improvements in the quality of the observed record provide evidence that contradict the notion of a hiatus in recent global warming trends.»

The crux of Bates» claim is that NOAA, the federal government's top agency in charge of climate science, published a poorly - researched but widely praised study with the political goal of disproving the controversial global warming hiatus theory, which suggests that global warming slowed down from 1998 until 2012 with little change in globally - averaged surface temperatures — a direct contrast to global warming advocates» claim that the earth's temperature has been constantly increasing.

Now if someone were to day, as Judith clearly did not although she had many opportunities to do so, that «concurrent with warming of our oceans there has been a hiatus in the significantly increasing trend of global surface temperatures,» then I would have not problem with the logic.

Now if someone were to dsay, as Judith clearly did not although she had many opportunities to do so, that «concurrent with warming of our oceans there has been a relatively short - term hiatus in the trend of significant increase in global surface temperatures,» then I would not have a problem with the logic.

I can see how it might be reconciled with a relatively short - term «hiatus» (if you must) in the trend of significant increase in surface temperatures, but not with a «hiatus in warming.»
