Climate change is slowly drying up the Colorado River
Annual water flow in the Colorado River decreased by over 11 percent due to warming in the 20th century, a new study estimates.
- Climate
Fossil fuel use may emit 40 percent more methane than we thought
Ice cores suggest natural seeps release less methane than was estimated, meaning industry produces nearly all of today’s geologic methane emissions.

The U.S. power grid desperately needs upgrades to handle climate change
The climate is changing faster than the U.S. power grid is adapting. Smarter grids and smaller grids could help.

Will Australia’s forests bounce back after devastating fires?
Intense bushfires that have blazed down Australia’s eastern coast could have long-lasting effects on the continent’s unique plants and animals.

Noise pollution from ships may scare Arctic cod from feeding grounds
Melting Arctic sea ice is opening up northern waters to increased shipping, and the vessel noise is taking a toll on Arctic cod.

Climate change may be speeding up ocean circulation
Circulation in the top 2,000 meters of the world’s oceans has increased as a result of faster winds around the globe, a study suggests.

A new roadmap shows how the U.S. could be carbon-neutral by 2050
A new report charts a roadmap for the U.S. to have zero carbon footprint by 2050, but only with heavy and immediate investment in carbon removal technologies.

Tiny meteorites suggest ancient Earth had a carbon dioxide–rich atmosphere
Simulations of reactions between 2.7-billion-year-old micrometeorites and atmospheric gases hint Archean Earth’s atmosphere had high levels of CO2.

The ‘Blob,’ a massive marine heat wave, led to an unprecedented seabird die-off
Scientists have linked thousands of dead common murres in 2015–2016 to food web changes caused by a long-lasting marine heat wave nicknamed the Blob.
