Steve Pearce has spent the last few decades quietly propping up and profiting from the oil and gas industry. His likely ascension to lead the Bureau of Land Management (BLM) is another sign that this administration favors profiteers over people and the public.

When Hurricane Melissa slammed into Jamaica, it unleashed torrential rainfall, life-threatening storm surge, and catastrophic winds. These types of massive storms—and the devastating impacts that result—are a sign of what is in store as the fossil-fueled climate crisis accelerates, scientists warn.

As global climate talks enter their third decade, the world’s biggest greenhouse gas emitter, the United States, is absent. The Trump administration, which formally withdrew from the Paris Agreement, has declined to send a delegation to COP30 in Belém, Brazil. That silver lining is new leadership.

Living beings have been wielding deadly molecules to kill each other for hundreds of millions of years. In response, many animals have evolved ways to survive these toxins. Scientists are beginning to unravel these defenses and hope as a result to identify better treatments for poisonings in people.
