No, ScienceDaily, Data Show No ‘Sharp Acceleration’ in Warming

ScienceDaily’s article, “Scientists detect a sharp acceleration in global warming,” promotes a new Geophysical Research Letters paper claiming that global warming has entered “a faster gear” since about 2015. This is false. The authors argue that after statistically removing the effects of El Niño, volcanic eruptions, and solar variability from five global surface temperature datasets, they detect a statistically significant acceleration in warming of about 0.35°C per decade over the past 10 years. But historical temperature data show a much different picture.
There is no convincing evidence that Earth’s warming has suddenly accelerated. Instead, this appears to be an exercise in statistical manipulation built upon climate modeling assumptions, presented as though it were an observational discovery.
And there’s advocacy behind the paper too, as evidenced by this quote from the paper’s co-author, climate science blogger Stefan Rahmstorf:
If the warming rate of the past 10 years continues, it would lead to a long-term exceedance of the 1.5°C limit of the Paris Agreement before 2030. How quickly the Earth continues to warm ultimately depends on how rapidly we reduce global CO2 emissions from fossil fuels to zero.
