What’s the German word for the opposite of a dunkelflaute?! Sunny and windy conditions in the U.K. currently pushing down fossil gas generation to only 6.5% on UK electricity grid grid.iamkate.com 🔌⚡️🌬️☀️

Was a real pleasure speaking to @elisecutts.bsky.social for Science on the beautiful new CO2 results over the MPT from Beyond EPICA presented by Florian Krauss at EGU. (And also nice to see them line up nicely with our CO2 reconstruction from boron!)

"What’s kind of striking is, in general in paleoscience, every time we have improved reconstructions of CO2, we find out that it’s playing the major role in climate.” - @mudwaterclimate.bsky.social www.science.org/content/arti...

@mudwaterclimate.bsky.social is a professor in the School of Earth and Environmental Sciences at @uniofstandrews.bsky.social. His research focuses on geochemical measurements to reconstruct past changes in climate to understand their causes so we can better predict changes in the future.

"Despite the difficulties getting everyone to agree on how to tackle climate change, real-world solutions are being implemented at speed almost everywhere." Love this #COP30 takeaway from @georginarannard.bsky.social. Just because countries aren't acting at scale doesn't mean the rest of us can't!

🚨 At least 10 scientists, all cited in the Trump admin's new climate change report, told me that the report completely mischaracterizes their research. I also found five citations with significant errors, and a paragraph missing an important citation.

Fascinating paper 👇 not only providing evidence for ocean acidification in the end-Triassic mass extinction, but also wider discussion of the role of reverse weathering in prolonging the effects, and how this changed with the evolution of open ocean calcifying organisms. ⚒️🧪

Super excited to share our latest on CO2’s role in geological climate change! Using boron isotopes in ~300 million year old brachiopod shells, we show that rising CO2 from volcanic emissions drove a profound change in climate that ended the Late Palaeozoic Ice Age ⚒️🧪🌊 www.nature.com/articles/s41...

A pronounced increase in atmospheric CO2 coincided with warming at the end of the Late Palaeozoic Ice Age, according to an 80-million-year-long boron isotope CO2 proxy record.

Nice thing about an 0830 sunrise is it’s easier to enjoy! Absolute beauty in St Andrews this morning.

Today my amazing colleague, lab mate, and partner @oceanicandrea.bsky.social officially became the first female Professor of Earth and Environmental Sciences @uniofstandrews.bsky.social. Let’s make sure it doesn’t take another 611 years to get the next ⚒️🧪🌊👩🏻‍🔬

We all think plastic pollution is a problem, and it is. In the nearly 70 years between 1950 and 2019, the world produced a total of ~9.5 billion tonnes of plastic. But all the plastic we have EVER produced weighs as much as CO₂ we emitted into the atmosphere during the first three months of 2024!

Storm Bert incoming! Great visualisation from earth.nullschool.net

Net zero emission means that CO₂ emissions are offset by removals, but what should count as CO₂ removal? This new study argues that countries should not count natural carbon sinks (like the ocean and forests) in their net zero emission targets.

I wrote this on 1.5°C eight years ago "Depending on climate sensitivity and natural variability, we could conceivably see the first year above 1.5°C as early as the late 2020s – but it is more likely to be later" It's looking like I was a bit too optimistic 🧵 theconversation.com/what-will-th...

What will the world actually look like at 1.5°C of warming?

By the time we hit that temperature, further climate changes will already be locked in and unavoidable.

Major fanboy moment last night meeting Octopus founder and CEO and all round energy transition champion Greg Jackson! Super fun chat on CO2 and climate. NB - thanks to Octopus flexible tariff I can fill up the 280 miles range on my Kia for £4.50!!! (And I obvs told him to get onto Bluesky) 🐙 ⚡️🔌🚗

Hello new followers! Lovely to have you over here. I tend to post on how past climates help us understand where we’re heading, including changes in ocean circulation, acidity, sea level, and CO2, as shown below. 🌊⚒️🧪🐚📈

James Rae@mudwaterclimate.bsky.social · 3y ago

Hey @bsky.app 👋 I’ll be posting stuff from our group on what we learn from Earth’s past climate that can help us understand where we’re heading - like the geochemical reconstructions below which show that CO2 is at its highest level in 3 million years 📈😬 www.annualreviews.org/doi/abs/10.1...

Repost this if you’re old enough to remember when they tried to convince us that “global warming stopped in 2008” (or whenever).

Nice nerdy contribution for geochemistry peeps - we use a new sequential leaching method to get accurate carbonate d11B from mixed matrix samples, demonstrated by getting true d11B from a coral, even when we filled the sample with clay! 🧪🌊⚒️ agupubs.onlinelibrary.wiley.com/doi/epdf/10....
