A volcano on Spain's Atlantic Ocean island of La Palma erupted Sunday after a weeklong buildup of seismic activity, prompting authorities to evacuate thousands as lava flows destroyed isolated houses and threatened to reach the coast. New eruptions continued into the night.

The Canary Islands Volcanology Institute reported the initial eruption shortly after 3 p.m. near the southern end of the island, which saw its last eruption in 1971. Huge red plumes topped with black-and-white smoke shot out along the Cumbre Vieja volcanic ridge, which scientists had been closely watching following the accumulation of molten lava below the surface and days of small earthquakes.

Pressure keeps building on increasingly anxious world leaders to ratchet up efforts to fight climate change. There's more of it coming this week in one of the highest-profile forums of all — the United Nations.

For the second time in four days, this time out of U.N. headquarters in New York, leaders will hear pleas to make deeper cuts of emissions of heat-trapping gases and give poorer countries more money to develop cleaner energy and adapt to the worsening impacts of climate change.

Nothing to eat, nothing to plant. The last rain in Ifotaka fell in May, for two hours.

Prince William announced 15 inaugural finalists Friday for the Earthshot Prize, his ambitious global environmental award that aims to find new ideas and technologies to tackle climate change, air pollution and the Earth's most pressing challenges.

The finalists include a 14-year-old student who proposes using solar energy to replace charcoal to power millions of roadside ironing carts in India; a land-based coral farm in the Bahamas to restore dying coral reefs; a community project in Congo devoted to protecting gorillas; and a Kenyan enterprise that turns organic waste into fertilizer and insect protein for farmers.

When a wildfire crested the mountains near North America's largest alpine lake, embers and ash that zipped across a smoky sky pierced Lake Tahoe's clear blue waters.

The evacuation order for thousands to flee their homes has been lifted, but those who returned have found black stripes of ash building up on the shoreline — a reminder that success fighting the Caldor Fire won't insulate the resort region on the California-Nevada line from effects that outlast wildfire season.

Firefighters wrapped the base of the world's largest tree in a fire-resistant blanket as they tried to save a famous grove of gigantic old-growth sequoias from wildfires burning in California's rugged Sierra Nevada.

The colossal General Sherman Tree in Sequoia National Park's Giant Forest, some other sequoias, the Giant Forest Museum and other buildings were wrapped for protection against the possibility of intense flames, fire spokeswoman Rebecca Paterson said.

Nine European countries on the Mediterranean are holding a summit in Athens Friday afternoon to discuss issues ranging from climate change to migration and Afghanistan.

The one-day gathering, dubbed the EUMED 9, brings together the leaders of Spain, France, Italy, Malta, Greece and Cyprus, and recent additions Slovenia and Croatia. Portugal is sending its foreign minister, while European Commission head Ursula von der Leyen will also attend the meeting.

Fire crews moved to ramp up the battle Wednesday against two expanding forest fires threatening Sequoia National Park's giant sequoia trees and infrastructure.

The Colony and Paradise fires, ignited by lightning strikes last week, covered about 14 square miles (36 square kilometers) in California's steep Sierra Nevada.

Nearly every nation is coming up short — most of them far short — in their efforts to fight climate change, and the world is unlikely to hold warming to the internationally agreed-upon limit, according to a new scientific report.

Only one nation — tiny The Gambia in Africa — is on track to cut emissions and undertake its share of actions to keep the world from exceeding the Paris agreement goal of limiting warming to 1.5 degrees Celsius (2.7 degrees Fahrenheit) of warming since pre-industrial times, the report said.

Environmentalists in Sri Lanka are challenging a court order issued earlier this month that would allow the return of 14 illegally captured wild elephants to people accused of buying them from traffickers.

Rights groups and lawyers say the Sept. 6 court order is based on a government decree that violates Sri Lankan environmental laws. They fear the order could encourage a resurgence of trafficking of wild elephants, putting them at risk.
