We haven’t just changed our weather. We’ve changed the climate in which our weather happens. climatelabbook.substack.com/p/learning-f...

Attributing Storm Austen Our experimental storyline attribution system suggests that 30-40% more rain fell during Storm Austen than would have done in a world without climate change climatelabbook.substack.com/p/attributin...

The 2026 UNEP Emissions Gap Report is out: The Point of Return. 🌍🌡️🔥 It's sobering but actionable. Decades of inadequate climate action have closed off opportunities to limit warming, but ambitious action today can still prevent much greater harm. A thread of some of the highlights 🧵

The warming will continue until we reach net zero emissions. At which point, we will need to live with whatever climate we’ve ended up in. The sooner we reach net zero, the less extreme that climate will be, and the easier and less costly it will be to adapt to it.

In our new study in @egu.eu Earth System Dynamics led by @derrickmuheki.bsky.social, we digitize & analyse 1 million+ temperature & precipitation observations from DR Congo 📜 From paper to proof: revealing Congo Basin warming through rescued climate archives esd.copernicus.org/articles/17/...

From paper to proof: revealing Congo Basin warming through rescued climate archives 1 million rescued weather observations from original paper sheets allow @derrickmuheki.bsky.social et al to clearly show warming in a region of very sparse historical observations esd.copernicus.org/articles/17/...

Another month, another reminder of how much our #climate is changing. September 2026 was the second warmest September globally, reaching 1.63°C above the pre-industrial level and marking a second consecutive month above 1.5°C. Read more: climate.copernicus.eu/climate-bull...

Drought-affected areas in Europe have expanded substantially in recent decades. ​ By the end of August 2026, meteorological drought affected around 46% of Europe, with 40% of the affected area under extreme drought, a much larger share than in 2025. See more: climate.copernicus.eu/european-sum...

People say my warming stripes screensaver looks nice but ruins their work breaks with reminders of the ongoing apocalypse. Now it can ruin Windows users' breaks too, thanks to Carey Blunt's port! github.com/gkaramanis/stripes-saver Stripes by @edhawkins.org #ShowYourStripes #dataviz

If you've used any climate datasets, you've likely benefitted from work of people like Simon. He is an unsung hero, helping build sub-daily to monthly global climate datasets on which we all rely over the past decade.

I made a macOS screensaver that draws the warming stripes one year at a time. It holds all 1,069 locations from showyourstripes.info and nine ways to build each picture. Free download. Stripes by Ed Hawkins @edhawkins.org karaman.is/blog/2026/10... #ShowYourStripes #dataviz #macOS

Europe didnt just experience an exceptionally hot summer in 2026. It experienced a summer where multiple climate extremes reinforced each other. First - temperature records were broken at daily, monthly and seasonal scales across Europe Read more: climate.copernicus.eu/summer-revie...

Another "need to extend the y-axis" moment... Average temperature in Central England for Jan-Sep for each year since 1772. It is 0.8°C higher in 2026 than any other previous year.

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/...

New version of the HadCRUT global temperature dataset released @colinmorice.bsky.social HadCRUT5.2 uses HadSST4.2 (with improved adjustments for SST biases during 1933-1961) and CRUTEM5.2 (with updates to stations in China, USA and Canada). Here is the difference from the previous version 5.1

📣 CCNow is thrilled to announce the winners of the 2026 CCNow Journalism Awards! Our awards program honors excellent reporting on many critical dimensions of the climate story. Together, their work constitutes the leading edge of climate storytelling. ...🧵↓

🌍 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...

22 feet (almost 7m). 2,000 years. One scarf. 99% blue, then the last little bit turns red. That's climate change, knitted, based on @edhawkins.org climate stripes. climateactually.com for the full story. #ClimateAction #Knitting #ClimateActually

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.)

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.

Think it’s time for a new extended temperature colour scale…

Summer 2026 is provisionally the UK’s warmest summer on record with the season’s mean temperature made around 130 times more likely due to human-induced climate change. Here, we delve into the numbers 🧵

A break in the clouds helped make D-Day possible. Ahead of the release of new film Pressure, University of Reading's Prof Ed Hawkins and ECMWF reconstructed the weather conditions of 6 June 1944, showing how a few hours either way could have changed history. Read more: https://rdg.ac/4hT1fQh

this is very cool

Climate change is increasing the intensity of extreme rain, and using multiple methods can increase our confidence in this. We've been working on a new storyline technique:

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
