Warming stripes for different layers of the atmosphere and ocean from 1960-2025. The ocean and troposphere are warming, the stratosphere is cooling.

Why global south voices are crucial in the fight against climate change - NCAS Not only are people in the global south most impacted by climate change, their voices are also under-represented in academia and media.

#ChangeNeedsAllofUs

Job opportunity! 3.5-year postdoc at the Dept of Meteorology, University of Reading, to improve convective storms in high resolution models using #EarthCARE and other data, including close collaboration with both ECMWF and the Met Office - deadline 27 February: jobs.reading.ac.uk/Job/JobDetai...

In April 1976, in a café at Cambridge railway station, Douglas Adams bought some biscuits. We know this because he told the story so many times that it somehow opened up a wormhole in the space-time continuum, travelling both forwards and backwards and, intriguingly, sideways in time. (1/some...)

Inside the Intergovernmental Panel on Climate Change (IPCC)

When it rains, it now rains more.

For those experiencing the flooding in south-west England, it is worth remembering that rainfall in winter has increased by about 25% overall.

And, the rainfall has also become more intense: when it rains, it now rains more, increasing the risk of flooding.

How much energy can be produced on global land currently used for liquid biofuels? Bar comparison showing energy per year from land currently used for liquid biofuels: Biofuels for transport — 1,400 TWh per year; Solar panels on the same land — 32,000 TWh per year. Side annotations: 31,000 TWh shown for context as the amount of electricity the world generated in 2024; 7,000 TWh per year shown as the amount of electricity the world would need to power all of its cars and trucks if they were electric. Note: This assumes the world uses 32 million hectares of land to grow crops for liquid biofuels, based on net land use which subtracts land allocated to co-products such as animal feed, and assumes solar PV uses 1 hectare of land per GWh. Data source: Energy Institute; Cerulogy; Ember; and author calculations. Chart is licensed CC BY to Our World in Data.

The world dedicates a Poland-sized area of land to producing liquid biofuels such as bioethanol & biodiesel. Is there a more efficient way to generate energy?

Putting solar panels on the land used for biofuels, e.g., would produce enough electricity for all cars and trucks worldwide to go electric.

Hover to measure: Meet the drones of atmospheric science - NCAS We spoke to research scientists at the National Centre for Atmospheric Science about the use of drones - also known as UAVs - in atmospheric science.

In deeply unsurprising news, the Earth continues to warm and the climate stripes continue their trip into the dark reds.

This will only continue to drive more and more extreme weather. The best time to act is today.

Ben Santer, an outstanding scientist and historically significant figure in the development of understanding of climate change, is relocating to the UK. Very much looking forward to him visiting the @metoffice.gov.uk to talk about our common research interests.

New favourite example of an eggcorn!

Okay, here's the story of George de Hevesy vs the Nazis! I really do love telling this story.

First, some background: George de Hevesy was a Hungarian-Jewish chemist, but he spent most of his career post-1920 attached to the Niels Bohr institute at the University of Copenhagen, in Denmark. (1/n)

Which option do we choose - act or delay?

These are the 'warning' stripes highlighting global choices. Do we act rapidly and keep global temperatures below 2°C, or delay and end up in a 3°C world (or worse)?

Open full Professor position in beautiful Scotland…

2026 outlook: likely another year above 1.4°C The Met Office outlook for the global average temperature in 2026 suggests an extension of the run of years with a value above 1.4°C, compared to pre-industrial levels.

Met Office 2026 global temperature forecast released today: very likely a fourth consecutive year above 1.4 C and >1.5 C possible again. Highlights the vanishingly small headroom we have to stay below 1.5 C to avoid the most severe impacts of climate change.

14 two-year postdocs for academics of any nationality who cannot continue their research due to US politics. Do share if you know of such.

Unlocking answers to climate change, air pollution, and high-risk weather in 2025 - NCAS We’re looking back at our science stories from this year, and highlighting the contributions our community of staff have made towards atmospheric science.

We know that understanding the atmosphere has never mattered more. As 2025 draws to a close, we’ve been looking back at our science stories from 2025.

Scientist at #AGU25 are speaking out to #SaveNCAR. Join more than 2000 of your colleagues to call or email your members of Congress to ask them to support NCAR today: agu.quorum.us/campaign/151...

Save NCAR from being dismantled today! The Trump Administration has vowed to dissolve the center that provides critical extreme weather and climate data for our nation.

If you are in the US and you would like to send a message to your elected representative about the proposed dissolution of the National Center for Atmospheric Research, @agu.org makes it easy with a template here: agu.quorum.us/campaign/151... #AGU25

In a large conference room full of people, the audience doesn't fit entirely in the frame of a photo. Nearly everyone pictured is standing.

At an @agu.org Town Hall today, @ncar-ucar.bsky.social President Antonio Busalacchi spoke to #AGU25 attendees about what's at stake if NCAR is dismantled.

One attendee asked anyone who uses NCAR research to stand up. Almost everyone in the room stood.

It is hard to overstate how critical @ncar-ucar.bsky.social is to climate science in the US and around the world. It's the beating heart of our field. Generations of scientists have trained there, and almost everyone I know relies on deep collaborations with NCAR scientists. It's end is unthinkable.

Would be an absolutely devastating blow for science on an international scale, not just within the US. Hard to comprehend.

The Telegraph has just published *yet another* correction to one of its net-zero articles.

By my count, that is now the THIRTEENTH such correction since Labour won the election (and covers 16 separate articles).

I have now added latest one to my epic thread which is tracking these corrections...

NCAR is a unique & valuable asset - far more than a climate model, or observations, or technology, or training ground, or gathering space. It covers weather, space weather, data, climate, paleo-climate, and everything in-between. It's building is an icon, but it's iconic status goes far beyond that.

It’s simply not possible to overstate how important NCAR is to US and world science. We need to fight this with everything we’ve got.

Back in 2018, I put together this timeline of landmarks in the history of climate modelling.

It featured this entry for 1964 about NCAR, which the Trump administration is now saying it seeks to destroy as part of its ideological war on science
