Saving Nature: 11 Women to Watch in Science These women are using their hard-earned knowledge to protect our planet already ravaged by brutal storms, epic floods and intense wildfires.

On this International Day of Women and Girls in Science, I am excited and humbled to have been selected as one of the 2026 Women to Watch in Science, featured by @thestoryexchange.bsky.social, alongside ten other wonderful scientists!

Another successful trip to the @agu.org Fall Meeting! Everybody gave great presentations and we got to celebrate our newly minted PhD, Dr. Ann Scheliga, as a group, with dinner, beignets, and live jazz music ! 🎢

See you next year in SF! πŸŒ‰

Science may be under attack, but inclusive science always prevails.

This tee is more than just a statementβ€”it’s a stand.

100% of profits go to AGU, which has supported scientists for over 100 years and continues to lead the charge to defend them today.

Satellites reveal tropical wetland flooding did not cause methane surge Human activity or other wetland factors like temperature or soil chemistry could be at play.

Vital research data is disappearing in front of our eyes! ⚠️ Right now, NOAA is being blocked from using satellite data to monitor sea ice loss. πŸ˜–
Not knowing how the Arctic is changing will not diminish its impact on our climate, it just makes us more vulnerable to the consequences.

Just about done with my 1st week as a Visiting Scholar at the @wmo-global.bsky.social where I will spend the summer! It has been a whirlwind of new faces and exciting projects to learn about, and I’m looking forward to contributing to the agency’s efforts on remote sensing of water and ecohydrology!

...that neither inundation 🌊 nor precipitation 🌧️ in the Tropics can explain the recent methane surge, suggesting that either ‼️ other controls of methane are responsible for the surge, or that non-hydrological controls matter more for tropical wetlands than presently understood ‼️
