If you're an environmental journalist in the UK or Europe, the biggest gathering of ocean scientists in the world is happening in Glasgow next week, and you should consider coming to cover some of the most important findings about our life support system. #OSM26
The implications of overshooting 1.5 °C on Earth system tipping elements - a review
"Global warming must peak below 2°C, return to below 1.5°C as quickly as possible (i.e. within this century), and to around 1°C thereafter to limit tipping point risks".

I feel physically sick. This cannot be normalised.
🎞️ After COP30 fire and floods: AMOC shutdown 🔥🌊
Our event on #AMOC shutdown was interrupted by the fire at #COP30 yesterday – but this is an important message so we wanted to make sure you heard it.

The Greenlandification of Antarctica
Antarctica is beginning to behave more like Greenland, with surface melt, ice dynamics, and climate feedbacks in Antarctica exhibiting "Greenland-like” traits, which have major implications for sea-level rise projections.

🧵🧪 In session on policy and societal requirements at the Royal Society discussion meeting today, Prof Hans-Otto Pörtner, former Co-Chair of the IPCC Working Group II, stated that he thinks keeping global temperature rise "below 1.5 [°C above pre-industrial] is probably now out of reach".
This would be laughable if it wasn't so serious: yet again, the Tories are claiming that we can get "all our oil and gas" from the North Sea and that we should be doing even more to support the industry to extract.
There are several reasons why we should treat this with maximum scepticism:
New paper! Check out @zifeiyang.bsky.social gorgeous data from M2 glaciation (3.3Ma) - stunning Melonis Mg/Ca temperature records allow us to be confident about ice growth, but this was not like later glaciations following iNHG, we think gateways were more important: www.nature.com/articles/s41...
The budget proposal eliminates:
NOAA’s Oceanic and Atmospheric Research office
Stops funding regional climate data, climate competitive research or sea grant programs
Severely defunds the Natl Ocean Service & the NMFS

📣 Our new paper is out in Nature Communications!
Subglacial water—often overlooked—can change sea-level rise projections by up to a factor of three. Big implications for how we model Antarctica.

You want to know about this NASA Sea Level Projection Tool, which allows you to visualize and download the sea level projection data from the IPCC 6th Assessment Report (AR6).
🧪🌊 🧵 As the minimum in Antarctic sea-ice extent has now dipped below 2 million km² for the third year in a row, it is looking increasingly like this is the new normal. In the 10 years up to 2015 the minimum extent averaged more than 3 million km².

This paper by Barker et al resolves many details about how Earth’s orbital wobbles caused glacial cycles of expansion & contraction of ice sheets over the last ~800,000 years 🧵 ⚒️🧪 1/11 www.science.org/doi/10.1126/...
Climate change in the polar regions of our warming world is threatening to transform many of its features, such as this icy tableau in the Fish Islands off the coast of the Antarctic Peninsula. There is still much to learn about these places before we know better what those changes may be.
A new special issue of Science highlights research on Earth’s frozen places—from the Arctic to the Antarctic—and how it’s changing due to climate change and the geopolitical challenges this important work faces.

Some people on this and other social media platforms have been claiming that something dramatic is about to happen at Thwaites Glacier, and implying that this will result of an abrupt rise is sea level within a few years. So what's really going on? 🧵🧪
Current policies & NDCs take the world to 2-3C in 2100, across a range of studies.
The biggest gap is strengthening climate action to ensure net zero pledges are met, leading to <2C in 2100.

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!
In our warming world there is an increasing chance of extreme rainfall events and flash flooding
For every 1C rise in temperature the atmosphere can hold 7% more moisture...
a cartoon with two panels panel one is a stick figure saying "oh! a fossil fuel!!" standing above a crudely drawn black lump under a brown ground Panel two is them walking away and saying "I'll just leave it there" The head of the person is not a drawn circle but the letter O, because the random software I used to draw it did that for unexplained reasons
Please allow me to re-share my rough sketch of some advanced carbon capture technology
It's the extremes that will get us. A hotter world has much hotter heat waves.

Changes in the #PolarRegions will affect everyone. Understanding and predicting this change needs commitment and talent; and that needs a supportive and inclusive community. Wishing everyone a happy #PolarPride as part of a wider celebration of #DiversityInPolarScience 🐻❄️🐧🥶🏳️🌈

The Met Office has been working hard to make more of our weather and climate data available for interest or research. I’ll share some links in a thread 🧪First up is our climate data portal climatedataportal.metoffice.gov.uk
While it's very funny to watch The Metals Company whine about the deep ocean oxygen discovery they helped fund, I worry that this only the start. Climate tech startups want science to support their business case, but many are going to discover that science is about reality, not their bottom line

Excellent piece from the Australian Sydney Morning Herald that puts the Chinese green industrial revolution in a balanced context and language most can absorb. Excellent journalism www.smh.com.au/environment/...
Warming stripes showing the increase in global temperatures from 1850 to 2023.
It's #ShowYourStripes Day. Here are ours.
As our planet warms, so does the ocean, sending warmer waters to Antarctica & under the ice shelves.
Ice shelves act as vital dams, holding back the ice sheets flowing to the sea & slowing sea level rise.

This is the right image to use for a heat wave; not one of children playing in the fountain or people frolicking on the beach.
