Global warming ‘hiatus’ erroneous, downturn in the global surface temperature not true after all

There is no missing heat.

New findings reveal the data may have been at fault; their miscalculation of the data.

The Intergovernmental Panel on Climate Change’s (IPCC’s) report that there has been a downturn in the global surface temperature, most especially in the most recent decades, has now been found to be untrue as a new US government research claims.

Even in the initial findings, it had been too good to be true. Particularly, when an unlikely year to denote the start of the global warming pause was 1998, the year in which a rather notable El Niño bad spell had occurred.

A reassessment has been done to the National Oceanic and Atmospheric Administration’s (NOAA) temperature record. For one, considering that vast improvements into the approach of measuring the global surfaces’ temperature from the past century to the new millennium are major leaps indeed.

Overall, the changes found had been slight, but certainly, have been removing the initial plateau that has now been debunked.

For many years now, climate scientists have been laboring to correct the bias in the data and Dr. Karl also says that, “It’s an ongoing activity.”

“There is no slowdown in warming, there is no hiatus,” said Dr. Thomas Karl, the lead author of the new paper that has unraveled the truth and the director of the National Oceanic and Atmospheric Administration’s National Climatic Data Center in Asheville, North Carolina.

As it had just been published in Science, in the week, it shows that within the last 15 years (0.116 degrees per decade) is; in fact, just a hairs breath in difference from the past five decades (0.113 degrees per decade).

“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,” says Dr. Gavin Schmidt, climatologist and director of NASA’s Goddard Institute for Space Studies.

“There’s been a lot of work done trying to understand the so-called hiatus and understand where this missing heat is,” Dr. Karl additionally says. From various studies done, a number of causes can be pointed to as the reason for the belief of this missing heat.

Heat transfer could have happened by a number of ways. Large and deep bodies of water, like the Pacific and Atlantic oceans, could have swallowed some of the heat. Large volcanic eruptions release sulphur dioxide into the atmosphere and this cools the planet for a couple of years by raising the planet’s albedo, which reflects solar radiation. Pollutants have also been shading the planet, albeit short term.
