Climate change deniers and sceptics have long pointed to satellite data showing lower temperatures than those recorded on the ground.
However, new research has found an explanation for this apparent discrepancy.
The orbit of satellites around the Earth gradually decays over time due to friction in the Earth’s atmosphere and this gradually changes the time they pass over any one spot and this obviously has a significant effect on the temperature.
Using information from the satellites, the scientists, Dr Carl Mears and Frank Wentz, of Remote Sensing Systems, a California-based research company, developed a new method of correcting for the changes.
And what they found was startling.
The rate of warming was about a third higher at 0.174 degrees Celsius per decade between 1976 and 2016, compared to 0.134C per decade.
Writing in the Journal of Climate, the scientists said: “The changes result in global-scale warming … about 30 per cent larger than our previous version …
