Equally as important, please check out the accompanying AWS public dataset for all the cloud-optimized point cloud files and COGs in this S3 bucket (s3://atlas-lidar-helheim/).

An 8-year record of daily and sub-daily ATLAS elevations and velocities when operational. The first of its kind!

My second-year student delayed her submission to this year so she could get preliminary results for her proposal. We were discussing her proposal plan today when this was announced. This is a shit way to bring up the next generation of scientists…

Waiting a year is an intentional and strategic choice. This offers more time to prepare and develop the best proposal possible. Taking this opportunity away in the final hour is a gut punch. They worked so hard and don’t even get to throw their hat in the ring. This is harm and generational impact.

Announcing such a major change to NSF GRFP this late in the cycle is incredibly cruel. 2nd yr students (mine included) have been working so hard on their proposals despite ongoing uncertainty. They are driven and passionate about being outstanding scientists and helping those coming up behind them.

This paper is the culmination of 5 years of work developing the first realistic and large-scale stochastic simulations of ice sheet evolution, and millions of core-hours of high-res Greenland simulations

This paper was co-led by Vincent Verjans and myself, and included important contributions from the whole Stochastic Ice Sheet Project (including Lizz Ultee, Helene Seroussi and Andy Thompson), which recently wrapped up after 5 years of work funded by @heisingsimonsfdn.bsky.social

What humans do to change climate matters much, much more than natural climate variations in determining future ice loss from Greenland 👉 Read about the results of the Greenland Ice Sheet Large Ensemble (GrISLENS) Project in our paper out now in The Cryosphere doi.org/10.5194/tc-1...
The Greenland Ice Sheet Large Ensemble (GrISLENS): simulating the future of Greenland under climate variability
Abstract. The Greenland ice sheet has lost ice at an increasing pace over recent decades, driven by a combination of human-caused climate change and internal variability in the climate system. In proj...

As a postdoc on the job market, I've been worried about the impact of ongoing funding/policy uncertainties on faculty positions. So I decided to compare the progression of faculty jobs this cycle to previous years based on positions posted to eswnonline.org/online/earth...
Line chart showing the cumulative number of Earth and Environmental Science faculty job postings by date added to the ESWN Jobs List for each hiring cycle from 2019–2020 through 2025–2026. The x-axis shows dates from April to August of the following year, and the y-axis shows the number of jobs (0–450). Each hiring cycle is represented by a line: earlier years (2019–2020 through 2024–2025) appear in progressively darker shades of blue, and 2025–2026 in red. Most years show rapid growth in postings from September to December, with totals levelling off by spring. The line for 2024–2025 shows a decreased growth after mid-November

“…researchers say the cost of natural disaster risk…is passed on disproportionately by insurance companies to people with lower credit scores.”
scrawford.bsky.social
Most U.S. home insurance rates aren’t driven by climate risk but mainly by credit scores. Crucial price signals about danger are getting lost, while lower-credit (often lower-income) Americans pay the most as risks climb. Needed: pricing transparency from insurers. open.substack.com/pub/susanpcr...
How insurance pricing obscures the real cost of climate change
Credit scores, not disaster risk, play a major role in home insurance prices — muting what could be an important market signal of physical risk

Shocking stats from this paper on the extreme 2024 summer heat in Arctic Svalbard, which lost 1% of its total ice volume in just ~6 weeks. 🔥

In fact, Svalbard's 2024 glacier mass loss actually exceeded that of the Greenland Ice Sheet, which is 50 times larger!!! 😱

The NSF-funded Arctic Research Consortium of the United States (ARCUS) will shut down at the end of Sept. ARCUS has been around since the late 80s; in recent years their staff had dwindled, and NSF said earlier this year that their grant would not be renewed. Another blow to polar science.
