Our work made the front page of the OC Register Sunday paper.
(I might add that my student, Ashley, and our work were above Sabrina Carpenter and Coachella...)

Thank you!
Hi Belinda, can you please email me the pdf? Thanks! joshbfisher@gmail.com
Climate change has increased global evaporative demand, except in S. Asia... Find out why/how inside!

I'll see you there!
I was named to the 2025 world’s “most influential” (top 1% by citations) scientists list (Clarivate Highly Cited Researchers 2025)!
Evapotranspiration data from OpenET were used in a US Supreme Court agreement between New Mexico, Texas, and Colorado over shared/disputed water. This is the first time that satellite remote sensing has been used in the US Supreme Court.

Nice!
Featured on the cover of @globalchangebio.bsky.social is a thermal image of Elaeocarpus Grandis taken at @jcuofficial.bsky.social Daintree Rainforest Observatory. In this species we find that populations originating from warmer climates have narrower leaves with higher rates of water loss.

The Gifford Fire is the largest fire thus far this year in California. Captured by ECOSTRESS.
Data visualized by high-school student Krishiv Jaini
Phoenix just hit the hottest Aug day in recorded history. ECOSTRESS saw it a couple days before with temps of 124F/51C at 9.20AM.
Data visualized by high-school student Kaitlin Cho.
Happening now! Largest fire in France in nearly a hundred years. Captured by ECOSTRESS.
Data visualized by high school student Bill Chen.
Compilation of fires burning in Portugal as captured by ECOSTRESS.
This image was a collaboration from multiple high school students piecing together the individual fires.

Sending ❤️ to Portugal, half of which is on fire right now. This fire, outside of Serabigões, captured by ECOSTRESS a few days ago.
Interesting volcanic activity happening at Hawai’i, captured by ECOSTRESS. Volcanic activity here seems to have accelerated anomalously since Dec.
Image captured by 16-year-old Shreyas Chatterjee working with me this summer.
Interestingly, some areas of the burn zone had low evaporative stress, and these areas did not burn. These images were compiled by 16-year-old, Justin Reinman, who lost his school in the fire. Justin is working with me on a detailed analysis of the evaporative stress for the fire.
Progression of Evaporative Stress from ECOSTRESS leading up to the Palisades fire in LA earlier this year. Things start off generally alright, then those winds smacked into LA and fast-dried the veg, which fueled the uncontrollable fires.
One of my students, Bill Chen, was looking at the Airport Fire in SoCal from last year using ECOSTRESS. Interesting to see the topographic variability in the temperatures.
Hydrosat picked up this scorching heatwave sweeping Europe yesterday. Surface temperatures exceeding 67C/150F! It’s great that we can now capture these temps at high resolution globally and with increasing frequency towards daily as we continue to get our constellation online. Stay safe out there!
Another new paper published today using ECOSTRESS again to predict wildfire—this time burn severity—one week before occurrence across New Mexico. This paper also outlines a framework for using machine learning with these data and applications.

New paper using ECOSTRESS and machine learning that predicted Australia’s black summer fires a week ahead of occurrence, mostly using high resolution water use efficiency and evaporative stress data.

Hydrosat poised to launch second thermal-infrared satellite
SAN FRANCISCO -- Hydrosat announced plans June 5 to gather thermal-infrared imagery with a second satellite launching later this month on the SpaceX Transporter-14 rideshare. VanZyl-2 has four times the imaging capacity of VanZyl-1,…
Inspired by @jtuttlekeane.bsky.social and @ohdearz.bsky.social, here's what the White House proposed budget cuts to NASA would do to the entirety of the agency's Science Mission Directorate.
Bloodbath is right.

My student, Holland Hatch, graduated today, won the top award for our major, and was selected to give the commencement speech. She’s traveled with me to Costa Rica & New Mexico serving key leadership roles. In short, she’s been amazing. I will miss her and wish her the best.
