It was a pleasure to be able to share my research this year at #AGU2025 @agu.org @agucryo.bsky.social

The Trump admin intends to dismantle the National Science Foundation National Center for Atmospheric Research (NCAR), one of the US' leading weather and climate research institutions.

We must urge Congress to halt this dangerous action immediately.

Later that morning (10:40): @dgrau13.bsky.social will shock and amaze you with the importance of melt lakes in driving hydrofracture and their role in accelerating projected Antarctic ice loss agu.confex.com/agu/agu25/me...

The Future of Antarctic Ice: New Study Reveals the Mathematics of Meltwater Lakes

New Paper Alert | Georgia Tech researchers developed a mathematical formula to predict the size of lakes that form on melting ice sheets. They discovered that lake depth and span are linked to the topography of the ice sheet. Their findings were published in @natcomms.nature.com.

Predicting mean depth and area fraction of Antarctic supraglacial melt lakes with physics-based parameterizations - Nature Communications This study uses the physics of bumpy surfaces to derive simple equations that predict the size of lakes that form from melt on the surface of ice sheets, finding that there are fundamental limits on t...

Thrilled for this paper @natcomms.nature.com led by @dgrau13.bsky.social‬, PhD Candidate @gtsciences.bsky.social, putting forward the first physics-based parameterizations for the area and depth of supraglacial lakes 🧵👇 www.nature.com/articles/s41...

International Asexuality Day (IAD) is celebrated worldwide every year on April 6th to recognize asexual people and to promote understanding of the ace umbrella. The day is dedicated to raising awareness and promoting the rights of the ace community.

Some federal workers are going back to work.

The USDA has been ordered to temporarily give over 5,000 workers their jobs back.

Dozens of CDC scientists have been reinstated after being illegally fired.

The National Science Foundation has rehired half of the workers it fired.

AGU has joined a lawsuit challenging the firing of probationary employees at federal agencies.

These actions weaken science, harm public health & the environment, and threaten national security. 🧵 #StandWithScience

Philly schools will continue to allow transgender athletes to participate in sports that match their gender identity The move breaks with PIAA, which passed a policy that sides with an executive order from President Trump.

Even in the face of the Trump administration’s attacks on trans people, institutions can and must protect our rights.

We commend the Philly school district and urge others to follow suit.

The IRS is expected to fire upwards of 6,000 employees as early as today.

This will mean fewer audits for rich tax dodgers.

According to U.S. Treasury estimates, the top 1% underpay their taxes by $163 billion every year.
