China has released plans to create the world’s largest carbon emissions trading scheme, several news outlets reported. The market will initially be focused on the power sector, which produced almost half of the country’s greenhouse gas emissions last year, and will encompass 1,700 energy suppliers producing more than 3 billion tons of CO2 annually, according to Reuters.

An imbalance between the trends in two common air pollutants is unexpectedly triggering the creation of a class of airborne organic compounds not usually found in the atmosphere over urban areas of North America, according to a new study from Caltech.

Carbon capture could help the nation’s coal plants reduce greenhouse gas emissions, yet economic challenges are part of the reason the technology isn’t widely used today. That could change if power plants could turn captured carbon into a usable product.

Human emissions of the potentially harmful trace metal vanadium into Earth’s atmosphere have spiked sharply since the start of the 21st century due in large part to industry’s growing use of heavy oils, tar sands, bitumen and petroleum coke for energy, a new Duke University study finds.

Visitors to the tiny island nation of Palau in the Pacific Ocean are now being required to sign a pledge that they will not damage the environment during their stay, The Guardian reports. It is the first such immigration policy in the world.

Frequent burning over decades reduces the amount of carbon and nitrogen stored in soils of savanna grasslands and broadleaf forests, in part because reduced plant growth means less carbon being drawn out of the atmosphere and stored in plant matter. These findings by a Stanford-led team are important for worldwide understanding of fire impacts on the carbon cycle and for modeling the future of global carbon and climate change.

Amphibians—the big-eyed, swimming-crawling-jumping-climbing group of water and land animals that includes frogs, toads, salamanders and worm-like caecilians—are the world’s most endangered vertebrates. 

One-third of the planet’s amphibian species are threatened with extinction. Now, these vulnerable creatures are facing a new foe: the Batrachochytrium salamandrivorans (Bsal) fungus, which is the source of an emerging amphibian disease that caused the die-off of wild European salamander populations.

Near the top of Cheat Mountain in West Virginia, bulldozer operator Bill Moore gazes down a steep slope littered with toppled conifers. Tangled roots and angled boulders protrude from the slate-colored soil, and the earth is crisscrossed with deep gouges.

The world’s largest ice sheet may be less stable than previously thought, posing an even greater threat to Florida’s coastline. The first-ever marine geologic survey of East Antarctica’s Sabrina Coast, published this week in Nature, concludes that some regions of the massive East Antarctic Ice Sheet have been sensitive to climate change for millions of years. Much like the West Antarctic Ice Sheet, this region of the East Antarctic Ice Sheet is grounded below sea level and local glaciers are experiencing ice mass loss due to ocean warming.

It may take until the 2060s to know how much the sea level will rise by the end of this century, according to a new Rutgers University–New Brunswick-led analysis. The study is the first to link global and local sea-level rise projections with simulations of two major mechanisms by which climate change can affect the vast Antarctic ice sheet.
