New paper in Population & Environment w/ @heatherrandell.bsky.social and led by PhD student Sara Ghebremicael! We find that hot/dry conditions during the main growing season and cold/wet conditions during the main harvest season both undermine household food security in Ethiopia:

A great paper in JEEM, which shows households in Zambia diversify crops, adopt resilient varieties, and expand land as a forward-looking adaptive response following exposure to drought. www.sciencedirect.com/science/arti...

My face when I hear that UNC is cutting grad admissions to the bone 😠

176 tiny maps (1850-2025) Maps of temperature anomalies for each year. The progression to warmer, redder colours is evident over virtually the entire planet. This 'small multiples' #dataviz approach is effective to show that nowhere is escaping from the warming due to us burning fossil fuels.

A little bit late, but I'm looking to hire a postdoc at Cornell to measure the private value of soil health improvements in US ag. A 2-year gig. Well suited for an ag/resource economist or data scientist w/ interests in soil health and solid programming & econometric chops. ad coming soon!

With data from >100k special issues, we set out to tackle this problem. Guest editors publishing in their own issues is a form of "endogeny". In this study, we define special issues with extreme endogeny as Published In Support of Self (PISS). So, how much of this literature is PISS? 4/n

In my latest newsletter I investigate what domestic migration patterns show about where Americans are choosing to live (and leave). Interestingly, the patterns often correspond better to ecoregions than political boundaries. Some of them surprised me. Read more:

“…an intro. sociology course on race and ethnicity was canceled, a comm. course on religion and the arts was renumbered and stripped of core curriculum credit, and a philosophy prof. was told to remove Plato readings and other material related to race and gender from a core course or be reassigned.”

From an email to one of our faculty members.... Not even Plato can escape censorship at Texas A&M!

Excited to share a new R package: 𝗵𝗲𝗮𝘁 🌡️ `heat` makes it easier to work with climate or other gridded data in applied research, providing a comprehensive + optimized set of tools to compute environmental exposures for admin boundaries or points from gridded/point data. github.com/echolab-stan...

"Nutrition is a central determinant of human health, yet the direct impacts of climate on dietary intake remain poorly understood ... [we] show that both extreme heat and cold trigger a shift toward energy-dense diets, adding a previously overlooked behavioral channel to the climate–health nexus."

This is one amazing photo. Jets of water vapour and ice crystals blasting out through four deep fractures in the icy shell of Saturn's tiny moon Enceladus. This is the only alien ocean we know of that we can directly access. (1/2)

New paper, led by Estelle McLean, on the value of data from Health and Demographic Surveillance Systems. These data sources are particularly suitable for complex longitudinal analyses which require consideration of household and familial contexts, but their complexity may result in their under-use

'Climate change is likely to keep more labour in agriculture in the very regions where its productivity suffers most. By the late 21st century, agriculture’s share of the economy in the poorest quartile of countries projects to be about 2.8pp higher than it would be without global warming.'

Climate change has affected the US economy, reducing per capita income by as much as 12.1% when accounting for indirect effects from temperature changes in all counties. Americans in the Great Plains and Midwest have been hurt the most. In PNAS: https://ow.ly/bR5t50XQ1m8

Today I have something really special for you guys! Not too far from the caiman I posted recently, I found something MIND BLOWING This is a butterfly pupa, and it mimics the head of a snake. And not just any snake, but specifically the head of a boa snake!!! Probably Opsiphanes, an owlet butterfly.

NEW!🦠🌡️ : What makes a "dengue year" like 2023-24? It's hard to pin down an answer unless you can homogenize out all the spatial variation and temporal trends. But once you do, the answer is pretty clean: dengue years are hot years. Last one of the year (unless...?) 👉 www.medrxiv.org/content/10.6...

The UNC system just released its final policy on mandatory syllabi disclosure, stating that syllabi are university (not faculty) IP and certain course info must be posted on new, publicly searchable databases before every semester. A thread about what's changed from the draft I reported on earlier:

“Severe Tornadoes & Infant Birth Weight”: In considering “environmental hazards as drivers of inequality & stratification,” @nickdemark.bsky.social et al. show how severe tornadoes led to ↓ in birth weight for the infants of Black mothers, esp. early in pregnancy. read.dukeupress.edu/demography/a...

Y'all, I just got out of the NSF-BIO webinar where they explained changes to peer review. It's not good. 🧪 scienceforeveryone.science/changes-to-n...

The International Monetary Fund asked me to review the literature on migration economics to draw lessons for low-income countries. In a new @iza.org paper, I argue that policy for the 21st century must discard four outdated ideas. www.iza.org/publications... 🧵 thread—>

"We use China's census data to test the predictive accuracy of four gridded population data products...they fairly accurately predict cross-sectionally [but] far less accurately predict temporal changes in population [and] predictive accuracy for changes has fallen substantially in the last decade."

Amazon tree boa (Corallus hortulana), an arboreal snake with many beautiful color morphs. This is one of the subtle morphs but I think it is stunning!

Two MA/PhD-level positions with POPCLIMA under Raya Muttarak at the University of Bologna:

America First, at America’s first public university.

Here is a map of the affected countries (excluding Tonga), to give you a sense of how much this new ban restricts immigration from Africa in particular. Of the newly-added country, Nigeria faces the largest impact, with tens of thousands of visas issued every year to Nigerians.

🚨☀️🔥 NEW: In August 2003, Europe was struck by a catastrophic heat wave. What can we learn from this event today? Using new machine learning and econometric tools, we show in PNAS that climate change contributed to 6,000 out of 15,000 deaths in France… (1/2) www.pnas.org/doi/10.1073/...

“…health disparities research is within the NIH’s priorities only if the area of research is “directly influenced by healthcare or biomedical science.” It gives poverty, employment and immigration as examples of areas that “would not be directly influenced by healthcare or biomedical science.””

Major env demography study finds rainfall caused >8% of deaths in Mumbai 2006-2015. The effect lasted over several weeks and was greater among young children, women, and low-elevation slum residents. Sea-level rise likely exacerbates this threat by overwhelming drainage systems.

NSF stopped the CNH/DISES program with the idea that they were going to roll out something new and better to replace it, and now we've got 0 and the folks who were working on this all were fired. I wonder if we wouldn't have been better off just keeping on with the old imperfect program.
