Putting the hot & dry summer of 1976 into context

50 years after the extreme summer for the UK and Ireland, what can we still learn?

For example, follow Storm Goretti’s forecast track, arriving over southern UK tomorrow evening…

Nullschool weather app for mobile phones...!
cambecc.nullschool.net Cameron Beccario @cambecc.nullschool.net · 5d
I'm excited to announce the official Nullschool app is here!

earth.nullschool.net on mobile browsers works fine, but the app is nicer. Full screen display, persistence across sessions, text size that matches device settings. Even landscape works well.

And, like the website: no ads!

Fancy working somewhere with views like this less than a 10 min walk from your office?

Are you an outstanding scholar of international standing within the field of Earth and environmental sciences?

Yes, or that we are lucky with our spatial sampling of observation locations!

Ed Hawkins @edhawkins.org · 5d
There is a figure in the Supp Info showing the bias but that doesn’t seem to be available at the moment…

Yes, Tambora, Laki, and a large unknown eruption in 1808/9.

Ed Hawkins @edhawkins.org · 5d
Thanks Kevin. It is the right thing to do, but we were actually quite surprised at the size of the differences between masked and unmasked. The coverage sampling bias was relatively small for most of the record.

It was the same background value as used by Met Office for their CMIP6 pi-control, which I think was a centennial average.

Ed Hawkins @edhawkins.org · 5d
Yes, same model, same natural forcings in 1750 and 1850 pi-controls. Only change was to anthro forcings to use 1750 values from PMIP.

edhawkins.org
Ed Hawkins @edhawkins.org · 5d
This choice was to mimic a CMIP-like design with 1750 base state. Other plausible choices possible!

edhawkins.org
Ed Hawkins @edhawkins.org · 5d
We performed both 1850 and 1750 pi-controls with the same constant small volcanic forcing like CMIP6. Only difference was anthro forcings.

Published today: Importance of beginning industrial-era climate simulations in the eighteenth century

Defining pre-industrial to be 1750, rather than 1850, produces different (simulated) historical climate changes after 1850. Pre-1850 volcanoes & land use matter.

What would the hottest UK day of 1976 look like today?

35.9°C back in 1976 would be 38-39°C now.

The hot extremes are warming faster than the average for the UK.

Although its very cold at the moment in the UK, 2025 was both the warmest (with a mean temperature of 10.09°C) and sunniest (1648.5 hours) on record. Here is a climate and weather #dataviz summary for the last year. #climatechange #globalwarming.

Climate stripes (as developed by @edhawkins.org @uniofreading.bsky.social ) displayed as a wrap in Liberty fabrics. It’s a Möbius strip so it's continuous from the darkest blue at the back for 1903 to the final dark red next to it which is 2024.

#showyourstripes
A fabric wrap made with stripes of patterned fabric ranging from dark to light blues through white to pale then dark reds, reflecting the climate stripes depiction of changing global temperatures, from 1903 to 2024. The back of the wrap showing where the Mobius strip starts and finishes with a dark blue (1903) next to a dark red (2024) Image from the Climate stripes website showing the data used to make the wrap

Yes, I did check the locations and it all looked plausible. Very low humidities at the summits too apparently.

It has been fascinating to watch recently. This one was between Christmas and New Year - @roostweather.bsky.social explained to me that the two warm sites were at high elevation above the inversion with cold sites in the valleys.
Hot or not?

2025 also set records for the amount of UK electricity produced by renewable sources (solar and wind).

Fossil gas now makes up 27% of UK’s total electricity generation.
