Aerosol pollution has long been included in climate modelling and it significantly slowed the warming trend in the 20th century. Clearer skies mean the full impact of greenhouse gases is no longer masked. Which is rather scary to be honest. 

More of a marked impact on summers than winters though.

"Temperatures in Europe have warmed twice as much as the rest of the world since the 1980s, figures show, with the continent now 2.3C warmer than it was in the pre-industrial era. In the same period, the global average is 1.3C."

"Experts believe this year’s heatwave was driven by the phenomenon, as well as the scorching European summers of 2003, 2006, 2015, 2018 and 2019"

At this rate though, we will soon be starting another new thread for heatwave number 5 in early August.

Apple apps are having none of this heatwave as only show mere warm 28C here and 29C London not a single day show 30C.  They been terrible wrong most of the time and undercook temps as far as 5C. Mine recorded 29.6C today while app show 25C.  I think they record temps in an areas like multi storey car park which always cooler than outside.

But yes when you have 46c forecast for Belgium it wouldn't take much for something like that here.

The most likely scenario has the heat heading further east but the 0Z GFS shows what happens if that low stays out in the Atlantic and just spins the heat up over us. 40C on two separate days, could still be a July and August monthly record to go with the May and June ones!

AIFS doesn’t really have the cut off low so we get a northerly after a few days of normal heat.  

GFS isolated this morning with the extreme heat.

And with temperatures much higher than they were back then, there's less comparable data to go on. The "AI" models were rubbish during winter (consistently showing easterlies which never materialised, they kept this up for weeks on end) and they've been almost as rubbish this summer. 

A blend of the two, as GEM is doing, is the way to go.

GFS is isolated with the extreme heat but it often handles cut of lows better than other models . So maybe it's onto something.

ECM although not as extreme is more like GFS than AIFS.

Nothing to see here, it’s all normal. 

In reality warming is uneven across the globe and Europe is seeing some of the fastest rates. Firstly you expect a differential rate for continents anyway, but secondly you also expect that pattern changes will exacerbate the problem in some places more than others. 

The removal of a mitigant takes us to where the climate would have been with GHG warming but without aerosol pollution. The absence of something that wasn’t there before industrialisation leaves us a couple of degrees higher than the pre-industrial average. That doesn't magically happen by introducing a coolant and then taking it away.

ECM 0z from Tuesday 

30c, 32c, 30c, 30c, 33c, 34c, 31c, 29c, 30c, 

You can normally add 2c or 3c to ECM max temps
