From the Guardian:
Temperatures in Europe have increased at more than twice the global average in the last 30 years, according to a report from the World Meteorological Organization (WMO).
The effects of this warming are already being seen, with droughts, wildfires and ice melts taking place across the continent. The European State of the Climate report, produced with the EU’s Copernicus service, warns that as the warming trend continues, exceptional heat, wildfires, floods and other climate breakdown outcomes will affect society, economies and ecosystems.
From 1991 to 2021, temperatures in Europe have warmed at an average rate of about 0.5C a decade. This has had physical results: Alpine glaciers lost 30 metres in ice thickness between 1997 and 2021, while the Greenland ice sheet has also been melting, contributing to sea level rise. In summer 2021, Greenland had its first ever recorded rainfall at its highest point, Summit station.
The claim comes from a WMO report, featuring this graph:
The WMO is of course another UN organisation, so obviously cannot be trusted. Neither can any of its sources of data, such as NOAA, GISS and Berkeley Earth, which are based around homogenised data.
But what do we know about recent climate trends in Europe?
For a start, we know that the official Met Office data for the UK does not support the WMO’s claims. The warming trend since 1991 has only been 0.2C / decade, not the claimed 0.5C.
More significantly, even that warming trend has virtually disappeared in the last two decades.
As for Europe, the Our World in Data website has looked at climate trends in great detail on a country-by-country basis. But rather than using the flawed homogenisation method, they only consider weather stations with continuous data since 1950:
Increase of temperatures by continents 1950 to 2021
If you want to observe rising or falling temperatures over a long period of time, you need weather stations that not only existed over the entire period, but also provided continuous data. Looking at the period from 1950 to today, only 176 of the more than 4,000 weather stations worldwide remain.
These provide informative data from large parts of the world and show a general increase in air temperatures. Especially in the last 10 to 20 years, the temperature rose more strongly than in the previous decades. All 176 measuring stations provided continuous data during the entire observation period. Changes in these average values are therefore not due to the fact that individual stations failed for a longer period of time or new ones were added in particularly warm or cold regions. The 10-year average is given in each case.
In the regions of Central and South America, which are not shown, there were no weather stations that consistently provided corresponding values for the period under consideration.
Although they acknowledge warming since 1950, both globally and in Europe, significantly the trends for Europe are similar to the UK’s – no warming this century, and only a small amount of warming since 1990.
Interestingly most of the rest of the world shows a similar pattern, with the exception of Oceania. As in the UK, there was a definite rise in temperatures during the 1980s and 90s, but since then that rise has clearly stopped. This raises very big question marks about the reliability and accuracy of the official global temperature datasets.
