gizmodo.comWhich Is the Most Underestimated Climate Threat in the US?The many consequences of climate change are already unfolding across the U.S., and some require more urgent attention.

I was excited to share my input for this recent "Giz Asks" piece from @gizmodo.com, discussing which climate threats the U.S. most underestimates: gizmodo.com/which-climat...

Some important differences between the conventional physics-based models (European and American ensembles are 1st and 2nd panels) and the AI models (Google Deepmind operational and experimental ensembles are 3rd and 4th panels). The differences in both track and intensity are obvious. #Isaias

New paper led by @rowanuniversity.bsky.social’s Andra Garner looks at the history of sea level projections published from 1982-2025

🚨 New paper alert! 🚨 Our updated database and analysis of global sea-level rise projections made from 1982-2025 was published in @agu.org's Earth's Future today: agupubs.onlinelibrary.wiley.com/doi/10.1029/... Key findings below (🧵 1/6):

4) The inclusion of "low-confidence" sea-level projections in IPCC AR6 has greatly improved agreement between high-end sea-level projections from the IPCC and individual studies (🧵 5/6)

5) Across studies, the timings at which critical amounts of sea-level change occur is often similar for projections published in different eras and using different methodologies (🧵 6/6)

2) Long-term (beyond 2100) projections primarily appear only after 2010 in the literature, and are generally much less common than projections for the end of the century (🧵 3/6)

3) The range of the highest global mean sea level projections has broadened since 2007, with estimates since IPCC AR6 ranging from 0.6-2.0 m (🧵 4/6)

1) 95% of all sea-level change projections have been developed in the US, UK, EU, or Australia (🧵 2/6)

The @agu.org Chapman Conference on Updating Usable Projections of Future Sea Level in Montreal last week was a great meeting! I was glad to be able to attend, share a talk on my work looking at the evolution of global sea level projections, and hear from so many other talented experts in the field.

The Chapman Conference was a fantastic balance of talks, networking, and small group break-out sessions. I'll be excited to see what results it produces for critical upcoming @ipcc.bsky.social efforts!

Cuts to federal science funding means we’ll be more vulnerable to hurricanes and nor’easters here in the Mid-Atlantic.

Andra Garner@andrajgarner.bsky.social

When we cut critical Federal funds for science, we all pay the price. The impacts of this loss of scientific innovation will be felt especially acutely in our coastal communities. Check out my latest op-ed, published today in The Philadelphia Inquirer, to learn more! share.inquirer.com/iC6tHv

If allowed to go through, this will be catastrophic for science in the U.S., and by extension, the global community, given the vital role that the U.S. has played in the scientific community for decades.

My colleague, environmental scientist @andrajgarner.bsky.social, has a paper out about the variability and inconsistency of spring weather being a climate change concern. Tomorrow the forecast calls for a 40° change in temperature. (Never mind a third consecutive day of 90+ in May.)

Excited to share our latest work, published today in Eos! The U.S. has led and helped to fund about a third of all global sea level projections ever produced. Now, attacks on science in the U.S. have left the field at a precipice.

Story ideas come from weird places. Last month I turned on the AC 2 days after running the heat. Then 2 days later the AC was off and the heat on. This prompted the q: "Is this normal?" The answer: "I mean, what is normal anymore?" A jv with @emmarcourt.bsky.social www.bloomberg.com/news/article...

As I've watched temperatures push toward the 90s this week in New Jersey, but see the forecast lows that will threaten a freeze by early next week, it brings to mind the paper that my colleague Dan Duran and I published two years ago. journals.ametsoc.org/view/journal...

15 Apr

In our 2024 paper, we show that a warmer climate has made springtime temperatures throughout the state of New Jersey less consistent than in years past, and that temperature variations that do occur are becoming more extreme.
