Next week will be my first time attending the @ecologicalsociety.bsky.social Annual Meeting. I will be giving an invited talk on 'Remote Sensing of Fine-Scale Vegetation for Optimized Urban Heat Mitigation'. I am not anything close to an ecologist; so looking forward to stepping out of my bubble.

#EarlyCareer Researchers Committee, International Association for #Urban #Climate is organizing a webinar to bring together insights from previous Alexander von Humboldt Postdoctoral Fellowship awardees in our field. Learn about the application process + practical tips. Register: lnkd.in/gw9UnsPS

There has been an explosion in #urbanheat monitoring using low-cost meteorological sensors. In our paper (doi.org/10.1175/BAMS...) in Bulletin of @ametsoc.org, we empirically show why we need to be careful about large biases in such sensors; & provide guidelines for their effective deployment.

If you are working on representation of #urban processes & dynamics in #models (process-based &/or #AI/ML), including model #development, #benchmarking, & #validation, consider submitting your abstract to our urban modeling session at #AGU26. Submit here: agu.confex.com/agu/agu26/pr... @agu.org

#Gemini is having an identity crisis.

No, I do not. I know how to write (for now).

In our just published #openaccess paper (doi.org/10.1038/s414...) in @natcomms.nature.com, we introduce U-HAT, a high-resolution #urban-resolving #airtemperature (AT) dataset that can more accurately capture the unique spatiotemporal patterns of AT over #cities. [1/n]

The Early Career Committee of International Association for Urban Climate was formed to strengthen #earlycareer representation within #urbanclimate community. To #earlycareer folks in this domain, please fill out this survey (forms.gle/hjpPiMVbi6pdF8QW9) so we understand how best to support you.

Will be in Austin next week. First, I will present ongoing work on 10 m #global #satellite detection of #urban #flooding at HydroML. Then, on Friday, I will give a seminar at UT Austin on better capturing the spatial variability of #urban #microclimate in process-based & #machinelearning models.

In our just published #openaccess paper in @natcomms.nature.com (lnkd.in/g5wRBXwU), we provide a comprehensive #global assessment of how background #climate & #urban #morphology jointly shape the #UrbanHeatIsland effect across 2,213 cities, & how these interactions may evolve in the future. 1/n

The existence of 𝘕𝘢𝘵𝘶𝘳𝘦 𝘊𝘪𝘵𝘪𝘦𝘴 is both a 𝗴𝗼𝗼𝗱 and a 𝗯𝗮𝗱 thing because it shows that the discipline has matured enough that funding intended for doing science can now be systematically siphoned off by Springer Nature to host branded PDFs on their website.

Half the Urban Heat Island effect is currently mitigated by tree cover globally--but benefits are greatest for wealthy cities + suburbs. Current tree cover can only mitigate 10% of urban temp increase due to climate; maximal planting could offset just 10% more. More from @science.nature.org here:

Trees halve urban heat island effect globally but unequal benefits only modestly mitigate climate-change warming - Nature Communications

Using global data from 9,000 cities, the study shows trees reduce half of the urban heat island effect but can offset only a small share of future climate warming, with cooling benefits unevenly distr...

In our recently published paper in @natcomms.nature.com (lnkd.in/gDyWxM7U), we provide a comprehensive #global assessment of how #urban #trees mitigate the #airtemperature (AT) #UrbanHeatIsland (UHI) effect, and how they stack up against future #climatechange related #warming. [1/n]

Heading to East Coast this week; first to give a seminar at the Yale Center for Geospatial Solutions on #satellite monitoring of #global #urban areas, then to Princeton to talk about better capturing spatial variability of urban #microclimate in both process-based & #machinelearning models.

Every day, I hit the nail on the head. At least that's what my good friend, #Gemini 3.1 Pro, tells me.

The impacts of #urban areas on #clouds & #precipitation are complicated due to multiple competing pathways. In our new @agu.org paper (doi.org/10.1029/2025...), we explore how the #Houston metropolitan area influences summertime cloud formation & #convective storms using both models & observations.

It's happening again (already an issue in the #urban #heat literature: arxiv.org/abs/2509.16568). #DataCenters can definitely create #heatislands, but using #satellite data would significantly overestimate the public health implications of it. Also, can we not have news articles on #preprints?

It is often claimed that as cities grow, the urban heat island (UHI) effect intensifies. In our recently published paper in PNAS Nexus (lnkd.in/ghZf5WAr), we show that historical #urban #heat dynamics have been far more nuanced.

Heading back to my alma mater, @yale.edu, next month! I’m giving a seminar on monitoring #global #urban #environments from space at the Yale Center for Geospatial Solutions on 4/22. Will cover #satellite #remotesensing of #urban #heat, #vegetation, #flooding, & #climate. Details: lnkd.in/ehSzd4RM

The chapter on 'Extreme Temperatures, Air Quality, and Public Health' of the book 'Climate Change Impacts in Texas' I wrote (with Melissa Allen-Dumas) has now been published. Link to chapter: lnkd.in/gKdf2iVN #extremeheat #climatechange #airquality #publichealth

In 2022 (back when #Twitter was still a thing), I had made this #meme about the state of #urban #climate #research based on an #xkcd comic. With all the recent changes in the #publication and #funding spaces due to the #AI + #machinelearning hype cycle, here is an updated version.

Your random forest model does not need a name.

A summary of recent key developments for #km-scale #urban-resolving #Earth system modeling is the feature article of this quarter's International Association for #Urban Climate newsletter: lnkd.in/gY7fDycp Related, a report (lnkd.in/gs3j4Mjs) I led that provides more details on these developments.

📢 Check out our just published paper (authors.elsevier.com/c/1mF0A9C~Iu...) in @cp-oneearth.bsky.social on present to future county-wise sociodemographic disparities in #moistheat ( #heatindex ) for different @ipcc.bsky.social scenarios for the #UnitedStates.

Have been getting a bunch of emails about Springer Nature's Discover XYZ journals over the last couple of months. Seems like MDPI/Frontiers got hold of a tuxedo. It's so over for #academicpublishing.

If you are attending IGARSS 2026, please consider submitting your abstracts to the #Community Contributed Theme focusing on monitoring #global #urban areas from #space we are organizing. The submission deadline is Jan 10th: 2026.ieeeigarss.org/Papers/Submi... And yes, our theme number is 42. :D

My citation collection has apparently crossed 5000, which is definitely a number.

Something strange is going on with @microsoft.com #Teams for the last few days, where it keeps flagging completely correct words. Unhelpful and distracting. I am sensing some #AI shenanigans.

I have promised 12 people that I will do 24 things by this weekend. I am hoping to finish 2 of those things soon. 👀

Will be in Austin next week for the Artificial Intelligence and Digital Twins for Earth Systems workshop (aidt4es.usacm.org). Looking forward to trying some Texas-style brisket😅; & yes, also presenting on several past/ongoing studies on applications of #machinelearning for #urban #microclimate.
