Combining two of Italy's delights — coffee and sunshine — a couple of engineers in Rome have created an environmentally friendly way to roast coffee beans without electricity or gas.

Antonio Durbe and Daniele Tummei have spent almost six years building and perfecting their sunlight coffee roaster.

Silflower was among native plants that blanketed the vast North American prairie until settlers developed farms and cities. Nowadays confined largely to roadsides and ditches, the long-stemmed cousin of the sunflower may be poised for a comeback, thanks to solar energy.

Researchers are growing silflower at nine solar installations in the Minneapolis area, testing its potential as an oilseed crop. The deep-rooted perennial also offers forage for livestock and desperately needed habitat for bees, butterflies and hummingbirds.

When a rotten egg smell rises from the mangrove swamps of southeast Mexico, something is going well. It means that this key coastal habitat for blunting hurricane impacts has recovered and is capturing carbon dioxide — the main ingredient of global warming.

While world leaders seek ways to stop the climate crisis at a United Nations conference in Scotland this month, one front in the battle to save the planet's mangroves is thousands of miles (kilometers) away on Mexico's Yucatan Peninsula.

With pledges for a United Nations climate conference, the world may be ever so slightly receding from gloomy scenarios of future global warming, according to two new preliminary scientific analyses Thursday.

The two reports — one by the International Energy Agency and the other by Australian scientists — focused on optimistic scenarios. If all goes right, they said, recent actions will trim two-or three-tenths of a degree Celsius (0.3 to 0.5 degrees Fahrenheit) from projections made in mid-October.

The generation of young people who will inherit a warmer future is telling the generation that caused carbon pollution to clean up its mess — from both inside and outside United Nations climate talks.

Or better yet, let us do it ourselves, many say.

Authorities on the Spanish island of La Palma are telling people who live near an erupting volcano to stay indoors because of a heavy fall of ash that has forced the cancellation of flights and school classes.

The Cumbre Vieja volcano on La Palma, which is part of Spain's Canary Islands off northwest Africa, has been spewing lava, ash and gases for more than six weeks. The eruption has alternately surged and ebbed since Sept. 19.

Four Latin American countries have announced that they will expand and unite their marine reserves to create a vast corridor in the Pacific Ocean in hopes of protecting sea turtles, tuna, squid, hammerhead sharks and other species.

The new marine corridor will connect the Galapagos Islands in Ecuador with Colombia's Malpelo Island and the Cocos and Coiba Islands in Costa Rican and Panamanian waters, protecting migratory species from fishing fleets of hundreds of vessels that visit the eastern Pacific each year.

World leaders have promised to protect Earth's forests, cut methane emissions and help South Africa wean itself off coal at the U.N. climate summit — part of a flurry of deals intended to avert catastrophic global warming.

Britain hailed the commitment by more than 100 countries to end deforestation in the coming decade as the first big achievement of the conference in the Scottish city of Glasgow, known as COP26 — but experts noted such promises have been made and broken before.

With each tide, Abdus Satter watches the sea erode a little more of his life.

His village of Bonnotola in southwestern Bangladesh, with its muddy roads and tin-roofed houses, was once home to over 2,000 people. Most were farmers like the 58-year-old Satter. Then the rising seas poisoned the soil with salt water. Two cyclones in the last two years destroyed the mud embankments that shielded the village from tidal waves.

Over five days abroad at two global summits, President Joe Biden showed a new willingness to openly confront China over climate change and its lack of leadership on the global stage.

Biden ended his time at the U.N. climate summit in Scotland on Tuesday by chastising Chinese President Xi Jinping for physically skipping the event and failing to make the level of commitments that roughly 100 other nations did to curb greenhouse gasses. Xi also avoided the earlier Group of 20 summit in Rome, allowing Biden to dominate the conversation as he met with his French, Italian, British and German counterparts.
