Scientists made an incredible discovery in November: acres of giant, pristine, rose-shaped corals blossoming from the sea floor in what's known as the ocean's "twilight zone."

Why would those who care about climate change choose to buy up coal mines or oil drilling rights? There's one surprisingly good reason, writes Richard Fisher.

Planetary-scale engineering schemes designed to cool Earth's surface and lessen the impact of global heating are potentially dangerous and should be blocked by governments, more than 60 policy experts and scientists said on Monday.

New results from a long-running public opinion survey show that about 1 in 3 Americans is now "alarmed" by global warming. Is it any wonder, given the horrific onslaught of fires, floods, heat waves and other climate disasters we've experienced in the last year alone?

Tiger sharks normally like to swim around the warm waters of Florida and the Caribbean. However, as the Earth’s ocean temperatures climb to new levels, they can begin to be seen as far north as New England. NBC’s Kerry Sanders reports for TODAY.

Chile has lots of lithium, which is essential to the world’s transition to green energy. But anger over powerful mining interests, a water crisis and inequality has driven Chile to rethink how it defines itself.

A historic deep freeze that crippled Texas. A deadly hurricane that wreaked havoc from the Gulf Coast to the Northeast. A record-shattering heat wave and historic drought in the West. And a devastating, out-of-season tornado outbreak that tore through towns in the Central and Southern US.

Planting trees is a necessity to help remove carbon from the atmosphere. However, it’s not enough. Yes, there has been a lot of awareness around planting trees. Even Elon Musk has been advocating for planting trees. However, a new study has found that protecting ecosystems should be the first priority.

As more and more billionaires jet off into space, public opinion is shifting on where their vast sums of money should be spent.

Ecologists thought these trees had long been torn down in New England. Then Bob Leverett proved them wrong. I meet Bob Leverett in a small gravel parking lot at the end of a quiet residential road in Stockbridge, Massachusetts. We are at the Ice Glen trailhead, half a mile from a Mobil station, and Leverett, along with his wife, Monica Jakuc Leverett, is going to show me one of New England’s rare pockets of old-growth forest.

A PERFECT STORM is ravaging the Arctic—literally. As the world warms, more lightning systems are igniting more peat fires. They burn through ancient buried plant material and release great plumes of greenhouse gases, which further warm the planet. At the same time, as plant species march north thanks to a more hospitable climate, the Arctic is greening.

Dammed rivers could accelerate climate crisis as creatures move into previously inhospitable areas

Half a mile south of what's left of the old Gold Rush-era town of Greenville, California, Highway 89 climbs steeply in a series of S-turns as familiar to me as my own backyard. From the top of that grade, I've sometimes seen bald eagles soaring over the valley that stretches to the base of Keddie Peak, the northernmost mountain in California's Sierra Nevada range.

The movie Don’t Look Up is satire. But speaking as a climate scientist doing everything I can to wake people up and avoid planetary destruction, it’s also the most accurate film about society’s terrifying non-response to climate breakdown I’ve seen.…

Warmer winters are happening across the globe, and can be drivers of catastrophic weather events and profound changes

The Boulder, Colorado-area wildfires — the most destructive in state history — were likely made worse by the effects of climate change, including extremely dry conditions and long stretches of record warm weather in recent months.

One thing that’s hard to grasp about the climate crisis is that big changes can happen fast. In 2019, I was aboard the Nathaniel B. Palmer, a 308-foot-long scientific research vessel, cruising in front of the Thwaites Glacier in Antarctica. One day, we were sailing in clear seas in front of the glacier. The next day, we were surrounded by icebergs the size of aircraft carriers.

Philip Van Wassenaer crouches down to pound nails into the base of a 25-metre-tall tree in Scarborough, Ont. He isn't tapping for sap — the nails around the base of this tree will help him diagnose its health.

What will it cost if the climate exceeds the Paris Agreement temperature goals this century—even if we later remove carbon dioxide from the air and manage to bring temperatures back down to meet those targets by 2100? And how does that compare with the costs of staying below those targets?

On a barren lava plateau in Iceland, a new facility is sucking in air and stashing the carbon dioxide in rock. The next step: Build 10,000 more.
