Trump Administration’s Unified Agenda Suggests Major Reversals on Climate Safeguards

Climate Law Blog | 22 July, 2026
On July 3, the Office of Management and Budget released the Trump Administration's Unified Agenda for 2026. The document, typically released once or twice a year, compiles all regulatory actions that an administration plans to take during the covered period. Consistent with President Trump's aim of downsizing government, a large portion of the proposed rules reflect rollbacks of existing regulations. Many of these proposals would reverse important federal climate safeguards, including by reducing protections for federal lands; removing incentives for and imposing regulatory hurdles to the buildout of clean energy; and significantly scaling back air and water pollution limits.

Greenland’s outlet glaciers

AntarcticGlaciers.org | 22 July, 2026
The Greenland Ice Sheet sits in the Arctic, from 59-83°N, covering about 80% of the island of Greenland. It has a huge volume of ~2.9 million km3 (which would be equivalent to 7.42 m sea level rise1), and is drained by a series of outlet glaciers, where ice flows constantly to the margin2.

From rifts to reefs: the geodynamic origins of shallow coral reef habitats at passive continental margins

EGU Geodynamics Division | 22 July, 2026
Why do coral reefs flourish along some continental margins, while elsewhere they form scattered platforms and isolated atolls? In this new blog post, Dr. Zhibin Lei explores this question through the lens of biogeodynamics, showing how tectonics ca...

Andy Frazer’s Aquilops, and DinoCon 2026

One of the highlights of DinoCon 2025 for me was getting to meet Andy Frazer, who you may know from Dragons of Wales, Novosaurs, and his numerous and mind-blowing life restorations of dinosaurs. We had a few minutes for an unhurried, one-on-one conversation, and I bought some prints, a no-AI-in-paleoart button, and his book EX|TINCT, a hardcover omnibus of his EX|TERRA art books.

Proposed Bill Would Provide $125 Million in Funding for Methane Removal Research

Climate Law Blog | 20 July, 2026
Last month, three Members of Congress introduced a bill to provide $125 million ($25 per year for five years) in funding for research into methane removal, a relatively novel set of proposed approaches aimed at mitigating climate change. This marks the first time such a bill has been introduced into Congress, and, if passed, it would place the U.S. at the forefront of methane removal research.

Fifty years of ocean chemistry in one place: GLODAPv3 is here!

Working with marine carbonate-system observations has taught me how much effort lies behind every row of an oceanographic dataset: long hours at sea, careful sampling, laboratory analyses, calibration and quality control. A single bottle of seawater may represent only one place, one depth and one moment, but when many such samples are brought together, they can reveal how the ocean is changing.

Piedmont’s big-two rock quarries: a geology walk

Oakland Geology | 20 July, 2026
This is a walk I led recently, and I like it so much I'm writing it down. As we visit these two major former quarries in the Piedmont bedrock block, we explore some distinctive terrain created during the Pleistocene epoch. We also experience how this beautiful landscape appealed to the people who developed this part of Oakland and Piedmont.

Why the Same Soot Can Warm One City and Cool Another

Every time something burns incompletely --whether in a car engine, a factory furnace, a cooking fire, an agricultural field set alight after harvest, or a vast wildfire sweeping through savanna grasslands-- tiny particles of black carbon are released into the atmosphere. You might know these more simply as soot. These particles are so small that thousands of them laid side by side would barely stretch across the width of a human hair. Yet despite their minuscule size, black carbon (also known as aerosols) are one of the most powerful and perplexing drivers of climate change on the planet.
