A key project in the restoration of the Everglades moved forward Thursday with the signing of an agreement between Florida and the federal government to construct a huge reservoir south of Lake Okeechobee.

A new study by Simon Fraser University historical ecologists finds that Indigenous-managed forests—cared for as "forest gardens"—contain more biologically and functionally diverse species than surrounding conifer-dominated forests and create important habitat for animals and pollinators. The findings are published today in Ecology and Society.

It's not just the United States—other major polluters around the world have also been falling behind the climate goals they set for themselves under the Paris agreement.

SpaceX aimed to launch its third crew a little before sunrise Friday, this time using a recycled capsule and rocket.

As part of the Paris Agreement, nearly all countries agreed to take steps to limit the average increase in global surface temperature to less than 2 degrees C, or preferably 1.5 degrees C, compared with preindustrial levels. Since the Agreement was adopted, however, concerns about global warming suggest that countries should aim for the "preferable" warming limit of 1.5 degrees C.

This week's climate change summit features lots of talk from different nations about their goals for reducing carbon emissions. But in the weird world of national climate pledges, numbers often aren't quite what they seem.

President Joe Biden on Thursday doubled US ambitions on slashing greenhouse gas emissions, leading Japan and Canada at a summit in making new commitments that bring the world closer to limiting the worst climate change.

Gov. Gavin Newsom on Wednesday declared a drought emergency in two Northern California counties as he stood on the dry shoreline of Lake Mendocino.

Japan aims to cut emissions 46 percent by 2030, significantly more than previously pledged, the country's prime minister announced Thursday ahead of a key US-hosted climate summit.

Catalytic converters cut down on toxic car emissions, and, according to the U.S. Environmental Protection Agency, they're one of the greatest environmental inventions of all time.

Researchers at the Paul Scherrer Institute PSI have succeeded for the first time in looking inside materials using the method of transient grating spectroscopy with ultrafast X-rays at SwissFEL. The experiment at PSI is a milestone in observing processes in the world of atoms. The researchers are publishing their research results today in the journal Nature Photonics.

A historic moment has arrived for the Everglades.

Artificial spin ices (ASIs) are magnetic metamaterials with exotic properties that are dependent on their geometries. Over the past few years, many physicists have studied these materials, as their unique properties could be advantageous for a number of applications.
