Compound events in which coastal flooding and heat waves occur at the same time are happening more often as the planet warms

As much as 85 percent of U.S. emissions of sulfuryl fluoride—a rare greenhouse gas and common pesticide used to treat termites—comes from California

A beleaguered solar geoengineering project failed to conduct field tests because of opposition from environmentalists and Indigenous residents

About 20 percent of large wildfires in North America now burn overnight because of drought conditions, straining firefighting resources

A marine heat wave last year undercut efforts to regrow coral reefs off Florida’s coast. Conservationists are worried this year could be problematic, too

Observations from MethaneSat could be used to independently verify industry reports and enforce regulations on fossil fuel companies

In the two years since Russia invaded Ukraine, a chasm has grown between Russian scientists who are studying the Arctic and their counterparts around the world

Echo chambers of climate denial on social media are strongest in the U.S. Midwest and South and in states that depend heavily on fossil fuels

The U.S. Department of Energy will award up to $100 million for projects that remove CO2 from the atmosphere

NASA’s PACE mission aims to increase our understanding of Earth’s carbon cycle, pollution particles and ocean plankton

Rising temperatures are melting an area of the Swiss Alps where scientists have been working to collect centuries-old ice cores that contain evidence of past environmental conditions

Some scientists say the controversial fishing practice of ocean trawling stirs up buried organic matter, some of which makes its way to the surface in the form of carbon dioxide

Scientists accidentally discovered a new way of monitoring the Earth’s planetary boundary layer: high-flying great frigatebirds

Fiber-optic cables buried in the seafloor off Alaska are helping scientists study the thawing of underwater permafrost, which could release greenhouse gases

Hundreds of scientists warn that the world must rapidly phase out planet-warming emissions to avoid crossing dangerous climate “tipping points”

Here is a snapshot of the warming world, from sea-level rise to fossil fuel subsidies to renewable energy growth

The new U.S. National Climate Assessment details how climate change will alter nearly every aspect of American life—and how the U.S. can help avoid “potentially catastrophic outcomes”

Rising temperatures are increasing the likelihood of severe drought in Syria, Iraq and Iran

Climate scientists, including pioneer James Hansen, are pinning down a fundamental factor that drives how hot Earth will get

Warming waters pose a danger to Atlantic salmon. A new effort aims to lower the temperature in waterways used by the fish to spawn

Temperatures are skyrocketing. Extinctions are accelerating. Groundwater is being depleted. Humanity can limit damage, but it will take collective global action

As the climate warms, Arctic cyclones are lasting longer and becoming stronger, leading to more sea ice loss

Methane traps more heat in the atmosphere than carbon dioxide, but pulling it from the air could prove to be a more complex task than removing CO₂

Raging floods, intensifying drought and rising seas could affect saltwater intrusion
