Marine heat waves worsen hurricanes
A Science Advances study covered by WUSF analyzed 1,600 tropical cyclones that made landfall since 1981 and found storms crossing marine heat waves intensified more rapidly. Those storms were linked to 60% more billion-dollar disasters, after inflation adjustment, than storms that did not cross extra-hot water. The authors say forecasting, evacuation timing and coastal infrastructure planning should account for marine heat wave overlap.
Why it matters
It quantifies how hotter oceans translate into higher hurricane losses and faster escalation near land.

WUSF coverageEPA moves to repeal endangerment finding
On April 11, Southern Illinoisan reported that President Donald Trump and EPA Administrator Lee Zeldin announced a repeal of the endangerment finding, the legal basis for federal greenhouse-gas regulation from cars, trucks and power plants. The move adds uncertainty for state-level climate policy, including Illinois efforts to close coal plants, and is likely to face legal challenge. It marks a major shift in federal climate governance.
Why it matters
If upheld, it would sharply constrain federal climate regulation and reshape the legal framework for emissions policy.

Southern Illinoisan coverageEPA approves Kansas carbon capture project
Global Agriculture reported that PureField Ingredients received EPA approval to begin permanent geologic sequestration of CO2 from its Russell, Kansas operations. The company said carbon capture and storage will start after final commissioning and is part of an integrated food, fuel and carbon platform based on wheat feedstock. The approval gives the project a regulatory green light to move into operations.
Why it matters
It is a concrete permitting milestone for a carbon-capture project in the U.S. Midwest.

Great Salt Lake rescue plan remains vague
USA TODAY reports Utah has advanced legislation, donations and a site purchase to keep more water in the lake, but the federal $1 billion plan still lacks details and congressional approval.

Genomics tools target climate-stressed ecosystems
Times of San Diego reports scientists are sequencing corals, eelgrass and redwoods to find traits that could help restoration keep pace with warming and drought, though the work is still experimental.
Still unclear
OPEN QUESTION
Will courts uphold the EPA repeal?
The endangerment finding underpins federal greenhouse-gas regulation, so litigation could determine whether the rollback takes effect.
OPEN QUESTION
Can hurricane forecasts use marine heat maps?
The new study suggests hot-ocean detection could improve warning triggers, but it is unclear how quickly forecasting agencies can operationalize it.
