Roger Pielke Jr debunks Europe’s “Worst Drought in 500 Years Claim”:
Europe is in the midst of what has been called the worst drought in 500 years. According to a drought expert with the European Commission in comments last week:
"We haven’t analysed fully the event (this year’s drought), because it is still ongoing, but based on my experience I think that this is perhaps even more extreme than 2018. Just to give you an idea the 2018 drought was so extreme that, looking back at least the last 500 years, there were no other events similar to the drought of 2018, but this year I think it is really worse than 2018."
While a full analysis of the ongoing 2022 European drought remains to be completed, so too the drought itself, it is clearly exceptional if not unprecedented. In this post I take a close look at the state of understanding the possible role of climate change n this year’s drought.
Specifically, I report on what the most recent assessment report (AR6) of the Intergovernmental Panel on Climate Change (IPCC) and underlying literature and data say about the detection of trends in Western and Central European drought and the attribution of those trends to greenhouse gas emissions.
In Western and Central Europe — basically Atlantic France all the way to Moscow, north of the Mediterranean region and south of the North Sea region — the IPCC and the underlying peer reviewed research on which it assesses has concluded that drought has not increased and, logically, that increased drought cannot be attributed to human-caused climate change. The only exception here is that the IPCC has medium confidence in an increasing trend of soil moisture deficits in some subregions, however the IPCC has low confidence that this trend can be attributed to human-caused climate change. Looking to future, at temperature changes of 2C and more, at present the IPCC does not expect the current state of scientific understandings to change. But stay tuned — that’s why we do science.
