Everyday weather in a warmer world Imagine the weather patterns that happened in 1903 occurred again in a warmer world - how would that weather be experienced differently? Thomas et al. answer this question, highlighting the thermodynamic response of the climate: esd.copernicus.org/articles/17/...

Everyday weather in a warmer world

Abstract. How would the weather of a year from history be experienced in a warmer world? We reconstruct the weather of 1903 using a reanalysis system that assimilates only surface pressure observation...

🌍 54 million historical weather observations from 95 countries have been unlocked & made freely available online. 📚 With records dating back to 1837, the project enabled the discovery of an HMS Terror logbook & an international weather station network Read ⤵️ www.metoffice.gov.uk/blog/2026/ho...

How 54 million historical weather records are being made globally accessible

For more than a century, the Met Office's National Meteorological Archive has held a treasure trove of historical weather data, some of it dating back to 1837. Now, thanks to a major project, tens of ...

August 2026 was the warmest August ever recorded globally and the warmest month on record El Niño is pushing temperatures higher, but these records are occurring in a climate that has already been fundamentally altered by decades of burning fossil fuels heating our planet #Climate 🧪⚒️🌊

How much warmer was summer 2026 than 1976 for the UK? Interesting differences between daytime (Tmax) and nighttime (Tmin). 2026 was much warmer than 1976, including in rural areas. (The only exception is daytime temperatures in Scotland.)

Temperatures in 2026 were much warmer than 1976 except for daytime temperatures in Scotland.

News we could not be more excited to share: the description paper of our high-resolution dataset is now available for review and comment at ESSD. The record provides global coverage at 0.25° resolution, built from 58,311 weather stations extending back to 1750. Pre-print: tinyurl.com/9dw7jbnf

Global warming is set to cross 1.5°C, pushing climate risks and impacts to increasingly dangerous heights, a new UNEP report warns.   Predicted impacts include extreme weather and threats to human health and economies.

Over the weekend, a storm in the Baltic states caused significant disruption to power supplies and at least 2 deaths. An experimental reanalysis-based attribution approach suggests that ~20% more rain fell than if the same weather pattern had occurred in a world that was 1°C cooler.

A Baltic storm caused significant damage on 22nd August 2026, but more rain fell than would have done had the world been cooler.

Projection has become reality 22 years ago, Christoph Schär et al. published a landmark paper in Nature explaining that the 2003 heatwave was a harbinger of things to come. The study featured an iconic figure - shown in countless lectures - illustrating how outlandish the event was at the time

With the looming El Nino, what does this mean for UK weather? Likely wet? The major El Nino events of the last 50 years have all been coincident with a wet UK in late autumn into winter. The wetter winter part did not occur during the 1877-78 El Nino, which we think was the largest event on record.

All else being equal even a simple increase in the mean of the temperature distribution will lead to extreme heat above a particular threshold that's more frequent, more intense, lasts longer and covers a wider area (you'll have to imagine that third dimension).

Schematic titled "warming increases the intensity, frequency, and duration of extreme heat" which shows a temperature trace as a red line in three different climates (COLD climate, CURRENT climate and HOT climate) which only differ in that each one is warmer than the last by a constant offset. A fixed baseline and heatwave threshold are also shown as horizontal lines and these do not change. Areas that exceed the heatwave threshold are shaded pink. The pink shaded area is larger in the current climate than in the cold climate and smaller than in the hot climate. In the cold climate an annotation points to a single isolated pink-shaded heatwave and says "isolated heatwave". In the current climate an annotation points to three distinct heatwaves and says "more frequent, long heatwaves". Finally in the hot climate an annotation says "duration and frequency continue to increase" and "isolated cooler period" for there is only one short period that is not now classified as a heatwave.

Earlier in the summer I presented a figure showing how a comparable weather event to the summer of 1976 would be experienced in a warmer current climate. It would be 3-4°C hotter, with London hitting 38°C. Yesterday, that is exactly what happened.

Nope, it’s the weeks of hot, dry weather made more severe by global heating due to fossil fuel burning that has increased the risk of wildfires. The landscape is so dry that any ignition can start a fire that becomes uncontrollable. Fields of crops and grasses are not “rewilded” but have burned

38.0ºC at Pershore was an all-time record for the station by 0.9ºC (37.1ºC, 19th July 2022) and a new August record by OVER 3ºC (34.9ºC, 4th August 1990). Station records go back to 1957.

Spaghetti chart showing Pershore daily maximum temperatures for every day of the year from 1957 to 2026. Faint grey lines trace 68 years of historical data, forming a seasonal cycle from around 5°C in winter to a summer peak of roughly 28°C. A dashed red horizontal line marks the previous all-time maximum temperature record of 37.1°C, set on 19 July 2022. A dashed amber horizontal line marks the previous August maximum temperature record of 34.9°C, set on 4 August 1990. A thick red line shows 2026's observed temperatures climbing through an exceptional summer, with multiple spikes above 30°C across May, June, July and August, before peaking on 13 August 2026. A large bold '38.0°C' sits near the top of the chart, connected by an arrow to a glowing red dot on 13 August 2026, which sits above both dashed reference lines. A bold subtitle states this is a new all-time Pershore record, beating the previous record by 0.9°C. A small UK map inset in the lower half of the chart marks Pershore's location in Worcestershire.

Horrific scenes in Stourbridge & Stoke-on-Trent today with several houses devastated by wildfires. The Fire Service are saying that the hot and dry conditions helped the fires to spread from grasslands to residential areas.
