It's official...GLODAPv3 is out! glodap.info 🌊

GLODAPv3 represents heroic foundational work necessary for, among other things, evaluating and improving the physical and biogeochemical ocean models used to predict consequences of human interference in Earth systems. Projects like GLODAP give us greater confidence in climate model projections.

Interested in understanding how the subsurface tropical Pacific has responded to GHG forcing? Interested in understanding whether models and observations agree on that response? Check out our recent paper in @jgroceans.bsky.social! agupubs.onlinelibrary.wiley.com/doi/10.1029/...

and also a record-breaking scientific and societal impact! ▸ 4 million ocean profiles ▸ 7,600 publications ▸ 340,000 citations

🌊 25 years of Argo and ocean observation records! ▸ 50,000 km: the longest journey ▸ 6,000 m: the greatest depth reached ▸ 16 years: the longest operational lifetime ▸ 3 years: the longest continuous mission beneath sea ice Challenge: can you guess which float achieved each records?!

"What's the use of having developed a science well enough to make predictions if, in the end, all we're willing to do is stand around and wait for them to come true?" -- the late, great Sherry Rowland

🌡Limiting global warming to 1.5°C has been the world's North Star for climate action. A critical benchmark against which policies are set and progress is measured. So, what happens if we breach it? We break it down➡️ go.wri.org/1-5-c-bs

A possibility we haven’t discussed enough is that they will start reinvesting in science but in a way where people have to sign away their souls. Things like: 1. You agree not to care about DEI in a meaningful or noticeable way 2. You agree to serve the Pentagon if they call 🧪

A massive marine heat wave in the Pacific, spanning an area 8x the contiguous US, is expected to intensify storms, exacerbate heat waves on land, and raise sea levels, particularly along the California coast. Climate change will increase the frequency and intensity of marine heat waves.

New study published last week: Northern high latitudes could become a net carbon source below 2 °C global warming 🌍 See more here: doi.org/10.5194/esd-... With co-authors Eleanor Burke, Dan Hooke, @njsteinert.bsky.social, @mathisoncamilla.bsky.social & Luke Smallman.

The men in that photograph believe they represent America’s future. The historian in me knows better than to make predictions, but the record is clear: those who have bet against Black Americans claiming their rightful place in this country have always lost. 🗃️ open.substack.com/pub/kevinmle...

A $3 @mta.info subway fare and some good Q train timing can buy you one hell of a view of the July 4th fireworks and the Brooklyn Bridge light show! Huge shoutout to the train operator for slow rolling over the Manhattan Bridge and the conductor for announcing it.

Hotter and hotter and hotter www.bbc.co.uk/news/article...

250 years of burning fossil fuels fuelled a record shattering humid heatwave in Eastern North America for the 250th anniversary celebrations on 4th of July. Turning any outdoor activities into a dangerous health risk. - @wwattribution.bsky.social www.worldweatherattribution.org/fossil-fuels...

It’s fossil fuels, not Mother Nature, that will kill people this weekend.

Another study by Bischof et al. 2023 found in dedicated model simulations "that cold subpolar North Atlantic sea surface temperatures significantly increase heat wave duration and magnitude downstream over the European continent." ⬇️ agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Welp, I guess I should go to bed. Tomorrow will be long and full of terrors.

The day of the underdog, I guess.

One of the big stories with this upcoming heat wave will be the dangerous overnight temperatures. Lows won't fall below 70°F, or even 80°F in places. This is consistent with the long-term warming trend and poses serious risks to human health. More U.S. climate visuals: zacklabe.com/united-state...

Check out this really great article below by @arstechnica.com, where he explores our recent @ukri.org funded research www.nature.com/articles/s41... and highlights future questions and debates it opens up ⚒️🧪🥼 @oxuniearthsci.bsky.social @oxfordgeography.bsky.social

We got a big bump in traffic yesterday when people learned about us on NPR. Thank you to @npr.org for covering our launch and bringing our story to people's attention! And thank you to all our new followers. We can do this together! 🌍️🧪💪 #ClimateAction #ClimateForUs #ProtectScience

The paper is available at Nature Climate Change @natclimate.nature.com www.nature.com/articles/s41... and on my homepage andreasschmittner.github.io

🚨 📰 🌊 🥼 💻 🧪 🧑‍🔬 New publication on future changes in ocean carbon cycling lead by Samar Khatiwala. We applied a new decomposition into preformed (saturation and disequilibrium) and regenerated (soft tissue and carbonate) components, which is more accurate that previous methods.

Two 7+ earthquakes in Venezuela. Worried for folks there. All communication lines seem to be cut. What a devastating year for the country and its people...

Tipping points in the Earth system are becoming a global challenge: a UN brief, based on PIK research, highlights growing risks to ice sheets, coral reefs and the Amazon. www.pik-potsdam.de/en/news/late...

Absolutely thrilled that the Overshoot Conference is going into its second round. This year at @tsinghuauniversity.bsky.social. Call for abstract out now - hope to welcome many familiar and new faces.

New paper led by Patric Simões Pereira presents evidence for a reduced West Antarctic Ice Sheet during late Quaternary interglacial periods from analysis of ice-rafted debris in Amundsen Sea sediments. doi.org/10.1029/2026...

A travesty. Springer Nature offloads SciAm—the most storied science magazine in the US—onto a content mill consortium, LabX, during an almost certainly successful union vote. LabX now says it will lay off 15 people, over 1/3rd of the unit and 60% of the bargaining committee. Pure union busting.

Surprising result: Temperate local extinctions from climate change are outpacing tropical extinctions. Across 39,157 sites, climate-related local extinctions affected 49% of temperate species compared with 33% of tropical spp. Biodiversity loss is a global crisis. www.nature.com/articles/s41...

🚨New Publication Alert!🚨 My @noc.ac.uk colleague, Adrian Martin (et al.; @aniekebrombacher.bsky.social) has revised our seafloor benthic ecosystem model, #BORIS, using new datasets and extend the range of organisms considered. If you have a (benthic) problem, if no one else can help, etc. ... 🌊 🦑

As well as extending the size range considered, BORIS-2 also now factors in seafloor temperature and treats bacteria more self-consistently and harmoniously than its predecessor, BORIS-1. What's not to like? Adrian's even packaged up BORIS-2's code nicely so you can have a quick go with it ...

Great talks this morning from the #NCAR 2026 CESM workshop. David Lawerence gave a comprehensive overview of all the work done with CESM. Very impressive. And this year's CESM distinguished achievement award went very deservedly to @ckoven.bsky.social. Great coverage of the TCRE/ZEC work, Charlie!

As is the annual tradition, we hope many of you will take the opportunity to use the Climate Stripes this week to start important conversations about the risks from, and solutions to, climate change. Officially, #ShowYourStripes for 2026 is on Sat 20th June. www.ShowYourStripes.info

Recommended listen: For the Apocalyptic Optimist podcast, Dr Dana Fisher spoke to historian and author Dr Naomi Oreskes about how to “fight back” against climate misinformation.

Finally! I have found the spot to watch the next elections returns. And the next after next. Forever! #knicks

Dude.

Parade. Thursday. Manhattan.

Another great meeting completed - sea level rise projections synthesis and assessment. Thank you @bobkopp.net for organizing and your leadership in this effort!
