Absolutely incredible: Tuesday morning's high tide in #Miami exceeded the major flood threshold... that is the 1st time it has ever happened in the city's history without a hurricane storm surge. It tied (within 0.1 inches) the storm tides produced by Irene on Oct 15, 1999 and Wilma on Oct 24, 2005.

Do you research the intersection of climate change and health, but could use further guidance on working with spatial data? Apply for our in-person workshop in Nairobi, Kenya in collaboration with the APHRC February 1-2, 2027. Registration is free! z.umn.edu/climate-health-workshop.

This program is now open for next summer (iiasa.ac.at/early-career...). The IIASA Population and Just Societies program "particularly welcomes applications from candidates interested in population change, sustainable development, and well-being."

"The Department of Earth Sciences at Montana State University invites applications for a tenure-track Assistant Professor of Geography specializing in global change, risk, and resilience and the human dimensions of environmental hazards."

🆕 #Blog When Crises Disappear from View: The Growing Humanitarian Data Drought Humanitarian data systems are shrinking. Without fresh data, people in crisis become harder to see, harder to reach, and all too easy to overlook: https://on.cgiar.org/489j2fM @cgiar.org @wfp.org

Mesmerizing

I teach a climate change course to ~150 students each year. Back in 2022, we did some simple extrapolation to see when we reach 1.5°C under recent trends/variability etc. Since then, every year we've been updating those old graphs to compare. A lot has changed in four years...

DemSem tomorrow! #DemSemTuesday

Together with other scientists I’m suing the 🇺🇸 US National Institutes of Health for violating our 1st Amendment rights & censoring our health science. I’m ready to shine a light on the darkest days. Buckle up, read on. This gets pretty wild… THREAD

Also, the *only* marsupial of North Carolina.

"The Department of Environmental Studies at the University of Colorado Boulder invites applications for the Byers Family Chair in Environmental Studies to be appointed to a tenured position at the rank of Associate or Full Professor."

"The Population Studies and Training Center (PSTC) at Brown University invites applications for a postdoctoral position to start July 1, 2027."

On many campuses, fraternities appear more powerful than presidents. In this episode of College Matters, Holden Thorp, who had a tumultuous run as chancellor of UNC Chapel Hill, said frats and football are virtually untouchable. https://chroni.cl/4i6x5re

🆕 Ocean acidification is raising newborn deaths in coastal communities Today on VoxDev, Alex Armand (Nova School of Business and Economics) & Ivan Kim Taveras (University of Navarra) discuss ocean acidification in LMICs: https://ow.ly/SwTN50ZWJzU

Life expectancy is worse in Texas than in Saudi Arabia. One fascinating contrast among many. Enjoy! infogram.com/woolf-life-e...

Nifty new research from the IOM and pals: 'we introduce Flow, a global dataset of bilateral migration flows by sex at annual resolution since 1960' (to 2024)

18th Conference of Young Demographers will happen on 3–5 February 2027, Prague The conference is fully on-site and in-person. The Call for Papers is now open and you can find absolutely all necessary information here. Submit your abstracts until Monday, 26 October 2026.

Forest fragmentation increases local temperatures in temperate and tropical zones and has a stronger effect on local temperature than overall forest cover, according to a study of high-resolution remote-sensing data from around the world. In PNAS: https://ow.ly/QZjT50ZUyMj

Harvard's population program is recruiting postdocs popcenter.harvard.edu/postdoctoral... Seems like a great opportunity!

Global warming raises mortality through more than heat: 1°C increases annual deaths by 2.5 per 1,000, and adverse economic effects explain two-thirds of the gap, from @AdrienBilal, @drkaenzig, and Krzysztof Lisiecki www.nber.org/papers/w35832

Population projections often assume that future fertility rates will stop declining after falling below some threshold, but that is at odds with global historical patterns, from Diane Coffey, @MikeGeruso, Dean Spears, and Sangita Vyas www.nber.org/papers/w35824

An Atlantic Meridional Overturning Circulation collapse may overturn some of the effects of global warming—easing its impact on developing countries and instead harming more advanced economies, from @jlcruzalv, @klausvanieper, and @HansbergRossi www.nber.org/papers/w35811

Funding rates at NIH for ESIs fell by a third (R01) and half (R21) over the last two fiscal years (i.e. those partially or fully controlled by the current administration). These policies are going to have ripple effects on science for years to come.

New-  We've all heard about the spiraling, skyrocketing, and soaring rates of college tuition. In reality, undergrad net tuition education has been stagnant or even declining for roughly two decades. So why do very few people know this? www.chalkbeat.org/2026/10/01/w...

You've seen fireworks that look like jellyfish, but what about a jellyfish that looks like fireworks? The E/V Nautilus filmed this rare Halitrephes maasi jellyfish glowing like a firework at a depth of 4,019 feet (1,225 meters) off the coast of Baja California, Mexico. (📷: Ocean Exploration Trust)

We are letting thousands die without even the recognition that their deaths happened. The humanitarian system cannot work more effectively if it does not know where it is working and where it is not, and lack of data is freeing everyone (donors, implementers, perpetrators) from accountability.

Magical creatures don’t exist, eh? Roughly 400 million years ago, before the birth of trees, there were giant mystery cones called “Prototaxites,” which grew nearly 30 feet tall. We literally have no idea what they were. Plant: no Mushroom: no Animal: no Tell me this isn’t a little bit magic

One of the most-viewed PNAS articles in the last week is “Spatially refined satellite gravimetry captures human signatures in global terrestrial water storage trends.” Explore the article here: https://ow.ly/ytuh50ZSNBp For more trending articles, visit https://ow.ly/YSuq50ZSNBo.

As the climate warms, compound drought and heat wave events are becoming more frequent and intense across the contiguous United States. Areas at high risk for such events are disproportionately poor, unhealthy, and rural. In PNAS: https://ow.ly/nqfA50ZSNx3

A new global database mapping 40 years of satellite and ocean data reveals that compound marine heatwaves and acidification extremes occur more frequently than expected. Experts warn more research is urgently needed to assess their impacts on marine life and fisheries. By María Paula Rubiano A.

Beyond excited to announce that Grace Venechuk and I had a paper come out yesterday! We used 9 (!!) publicly available data sources to analyze associations between population health, wildfire smoke exposure, and county-level occupational compositions. link.springer.com/article/10.1...

Hurricane Polo is looking extraordinary tonight. Sheesh.

Another stunner from JWST—this time part of a *much* larger scene I'll post later. This portion is made up of stars and protostars in a cluster about 1,000 lightyears from Earth. The bright, multi-point features are nearby stars. The smaller features in the background are other galaxies.
