UK heatwave: How do temperatures compare with 1976?

by P. Homewood, July 24, 2022 in NotaLotofPeopleKnowThat

People on social media have been comparing the high temperatures in much of the UK with the heatwave of 1976, suggesting that the severity of the current hot weather is being exaggerated.

So, what does the evidence show?

How hot was the summer of 1976?

The peak that year was 35.9C. That has been beaten by the current temperatures, with 40.3C recorded so far.

The heatwave of 1976 started in June and lasted for two months. There was a lack of rainfall and a significant drought, with the government enforcing water rationing.

The heatwave was rare for that decade. The average maximum temperature in July in the 1970s was 18.7C. In the 2010s, it was more than 20C.

The European Heat Wave and Global Warming

by Guest Blogger, July 21, 2022 in WUWT

From the Cliff Mass Weather Blog

There is a lot of talk about the short-term European heatwave with some suggesting that the record-breaking warmth is the result of climate change/global warming.

Some of the media and climate advocates have been over the top in their claims (see below), stating that this event was the result of human-caused global warming.

Global Warming Has Stalled Over Much Of The Last 10 Years, Arctic Never Melted Away

by P. Gosselin, July, 22, 2022 in NoTrickZone

The globe hasn’t been warming and the Arctic hasn’t been melting much for almost a decade now.

Recall the climate crisis loonies warned us some 20 years ago the Arctic sea ice would disappear by the summer of 2014. Well it’s still very much there, as Joe Bastardi reminds us at his most recent Saturday Summary:

…

No warming in 8 years

Moreover, UAH global mean temperature anomaly hasn’t risen in eight years as well, Hat-tip Snowfan here:

Was It Hotter In 1911?

by P. Homewood, July 23, 2022 in NotaLotofPeopleKnowThat

There has inevitably been a lot of apoplectic reporting about this week’s heatwave in Britain. Everybody from the BBC to the Met Office have been blaming it on climate change, with suitably scary colours to ram the message home:

But so far I have not seen an objective analysis.

So let’s start with a few simple facts:

1) It was extremely hot for a couple of days this week.

2) The heat was the result of an extremely unlikely set of meteorological conditions – a perfect storm, if you like.

We know this because the Met Office told us so. On July 8th, they announced the possibility of a heatwave a week later. The weather model runs produced a wide band of possibilities, with most predicting similar temperatures to the weekend before, and some even forecasting no heatwave at all. At that stage on a couple of models out of the hundreds run predicted 40C temperatures, which were described by the BBC as “a very tiny possibility”.
