Followed up last week's walk along the southern part of Devil's Dyke (sixth century earthwork along the Cambridgeshire-Suffolk border) by walking the central section today. Still plenty of pasque flowers blooming on open areas of the southwestern slope.

🧵🧪Atmospheric CO₂ concentration rose to more than 430 ppm this weekend as it climbed towards its annual maximum. In April of the year that I was born it averaged 319 ppm. That's a 35% increase within my lifetime. 1/n

“Critics once described Brexit as the greatest act of economic self-harm by a Western country in the post-World War II era.” Trump will top that in the US.

1. For the past thirty years I've had the best job in the world.  I've had the opportunity to follow my curiosity; explore the workings of nature and society; mentor students and junior colleagues in the same process; and teach generations of students about it all.

We’ve done the hard journalism: we collected the best penguin memes born from Trump’s utterly unhinged tariff list. From frozen rocks to free trade – this is the trade war content you never knew you needed. 🐧 @eastangliabylines.co.uk

Mer de Glace 1969 | 2024 We are a world away from the 20th century climate, already in uncharted territories, and that's just the beginning! 😱 Losing glaciers through sole human emission should make us take action 🛑 But we are apathetic... 📷 @glacionaut / IG

Scientists studying all aspects of the world’s climate system, witnessing the damage being done to research programmes essential to monitoring and forecasting future change, know without doubt that he’s no genius. When will the US public work this out? www.theguardian.com/us-news/2025...

1. We have enough information to act on the climate crisis NOW, even if every single measurement stops. 2. We need to know how bad it's going to get, and if our mitigation efforts are working. These can be true at the same time.

BREAKING from @science.org: The Trump admin is seeking to kill nearly all climate research at NOAA, its climate science agency. Its near-final budget proposal would end all NOAA research labs, academic institutes, and regional climate centers. And it wants to fully end the NOAA Research division.

🧵🧪🌊 With a little more than 2 months to go to the winter solstice in #Antarctica, sea ice is generally recovering fairly well from a near record minimum earlier this year. Not in the Bellingshausen Sea though. Hardly any new ice has formed there yet. 1/2

It's increasingly looking like East Anglia, normally the driest part of the UK, is heading for a very dry summer. Only 7 mm of rain recorded in Cambridge in March, and none so far in April.

Toying this week with the idea the hidden complexity of modern life is a barrier to advocacy. Most people don’t understand (and haven’t needed to!) how much basic facets of their lives rely on complex and interwoven global systems

🧵First country hike today since my Achilles injury in January, along the southern part of Devil's Dyke. The 12 km-long, 10 m-high dyke is thought to have been constructed in the late sixth or early seventh century by the Saxons, who ruled the part of East Anglia between it and the coast.

This evening's entertainment - a jig-map bought from a charity ship. I feel I should issue two cautions: 1. Reflects the attitudes and values of its time. 2. Not to be used for navigation.

One day, governments will realise that they let universities close the only departments that had the skills and knowledge to understand the subsurface, hazards, climate change, and where to find Earth's resources. And they no longer have the workforce for the sustainable future they promised.

Almost 90% of flights from Luton are taken for leisure, with more British tourists taking their money out of the country to spend abroad than tourists coming in. Expanding Luton is not good for UK growth & certainly not good for nature & the environment. Why doesn’t Labour Govt understand that?

You don't need to be a seismologist to look at this figure and understand the huge forces that ripped through Myanmar on March 28. The M7.7 quake ruptured fully 500km of the Sagaing Fault, moving its western flank north, with >3m of slip at the surface. Data from EU Sentinel satellites.
