The Winery I've found that is the farthest North  63.47°N A common trope from contrarian activists is that the roman warm period ( RWP ) and medieval warm period ( MWP ) were warmer than today. The proxy data we have conclusively show this to be false, but most of these contrarians reject the proxy evidence in reputable studies. Instead, you often hear claims based on a misuse of historical data, one example being that during the RWP and MWP, you could grow wine in England , but you can't now. Therefore, the globe was warmer then than now. One version of this trope is: The Romans wrote about growing wine grapes in Britain in the first century,” says Avery, “and then it got too cold during the Dark Ages .

England et al 2025 The publication of these two studies, plus coverage of at least the latter in the Guardian , has caused quite a stir among contrarians on social media, who are claiming this is evidence that AGW isn't really a problem after all, and perhaps natural variability is what's driving recent changes in sea ice extent and temperature. However, that's not the way the authors of these studies are saying. Instead, the authors see the long-term downward trend in sea ice as being very real and caused by human activity, but they are also saying ...
