Study: Climate change didn’t create trophospheric hotpots but erroneous study did

University of New South Wales researchers confirmed strong warming in the Earth’s troposphere.

It was confirmed by a published research paper in Environmental Research Letters, that there is a strong warming in the upper troposphere layer, known as tropospheric hotspot.

The troposphere is part of the global warming theory and in the global climate models.

ARC Centre of Excellence for Climate System Science Chief Investigator Prof. Steve Sherwood and the lead author of the research paper said, “Using more recent data and better analysis methods we have been able to re-examine the global weather balloon network, known as radiosondes, and have found clear indications of warming in the upper troposphere”.

They were able to accomplish this by producing a temperature and wind data set of the upper troposphere that began in 1958 to 2012.

The researchers extended a standing data record and removed the errors that were caused by the station movements and instrument changes. This resulted in a new datasheet that exposed the real temperature change in contrast to the artificial changes produced by alterations.

Sherwood said that they inferred what natural weather and climate variations appeared like from the available data. They discovered anomalies that looked like sudden one-off shifts from these natural disparities and removed them.

This was done by the using an established technique created in 1977 by statisticians.

The results revealed that there is a slowdown in the warming of the average global temperature on the Earth’s surface.  But, the warming has persisted strongly in the troposphere except for a thin layer around 14-15 km above the Earth’s surface where it has warmed less slightly.
