The move, affecting about one-fifth of the National Science Foundation’s primary research budget, is the latest sign of how the White House is asserting more control over grants.

Extreme event cost attribution is inherently ambiguous, because event alternatives can be viewed as changes in frequency or intensity Ambiguous single-event attributable costs can, in theory, be ...

The eruption of Vesuvius volcano witnessed by Pliny the Younger in 79 CE is dated by the argon-40/argon-39 (40Ar/39Ar) method to 1938 ± 13 years (SD) before measurement in 2025 CE. Achievement of 0.7%...

Abstract Earth’s climate has experienced periods of extreme warmth known as hothouse climates. In these states, surface evaporation is almost entirely balanced by absorbed shortwave radiation. However...

New document emphasizes support for White House priorities over curiosity-driven ideas

Spatial patterns of change in common heatwave metrics are largely explained by a mean shift of the daily maximum temperature distribution For a given mean shift, smaller climatological variance a...

The U.S. National Science Foundation was established in 1950 to keep American discovery at the frontier. That mission has not changed. The science and technology ecosystem around it has...

Climate warming lengthens the productive season in extratropical forests. Yet there is inconclusive evidence on whether this in turn elicits enhanced tree growth and forest carbon sequestration. In th...
