When ash began to fall and his throat was burning from the smoke, Franklin Thom decided it was time to leave the city where he grew up on the edge of the national forest in California.

He made it to a shelter with his daughter and just his medicine, some clothes and his shower shoes. Unlike some others, he was told that he had escaped California's largest fire of the year with his home still standing.

Drought and unusually hot weather have raised the salinity in Italy's largest delta, where the mighty Po River feeds into the Adriatic Sea south of Venice, and it's killing rice fields along with the shellfish that are a key ingredient in one of Italy's culinary specialties: spaghetti with clams.

At least one-third of the stock of prized double-valve clams raised in the Po Delta have died off. Plants along the banks of the Po River are wilting as they drink in water from increasingly salty aquifers and secondary waterways have dried up, shrinking amphibians and birds' wetland homes.

Seattle and Portland, Oregon, have set records for most consecutive days of high temperatures and authorities in Oregon investigated more possible heat-related deaths.

In Seattle, the temperature rose to 91 Fahrenheit (32.8 Celsius) by early afternoon, the record sixth straight day the mercury rose above 90 F (32.2 C). In Portland, Oregon, on Sunday temperatures rose above 95 F (35 C) for the seventh day in a row, a record for the city for consecutive days above that mark.

The Mona Lisa may maintain her famously enigmatic smile because she benefits from one of Paris' best-kept secrets: An underground cooling system that's helped the Louvre cope with the sweltering heat that has broken temperature records across Europe.

The little-known "urban cold" network snakes unsuspecting beneath Parisians' feet at a depth of up to 30 meters (98 feet), pumping out icy water through 89 kilometers (55 miles) of labyrinthine pipes, which is used to chill the air in over 700 sites. The system, which uses electricity generated by renewable sources, is the largest in Europe — and chugs on around the clock with a deafening noise totally inaudible above ground.

Richer countries failed to keep a $100 billion-a-year pledge to developing nations to help them achieve their climate goals, according to an analysis by the Organization for Economic Cooperation and Development, or OECD.

$83.3 billion in climate financing was given to poorer countries in 2020, a 4% increase from the previous year, but still short of the proposed goal. The United Nations-backed payment plan was first agreed in 2009 to help poorer nations adapt to the effects of climate change and reduce emissions.

Crews battling the largest wildfire so far this year in California braced for thunderstorms and hot, windy conditions that created the potential for additional fire growth Sunday as they sought to protect remote communities.

The McKinney Fire was burning out of control in Northern California's Klamath National Forest, with expected thunderstorms a big concern Sunday just south of the Oregon state line, said U.S. Forest Service spokesperson Adrienne Freeman.

So-called "ultra-fast fashion" has won legions of young fans who are able to snap up relatively cheap clothes online, but campaigners say the trend masks darker environmental problems. 

Hundreds of young climate activists marched through Turin on Friday, after a week of discussions on the future of the increasingly global school strike movement.

Spanish Prime Minister Pedro Sanchez on Friday called on office workers to throw sartorial caution to the wind and ditch their ties amid scorching summer temperatures.

Search and rescue teams backed by the National Guard searched Friday for people missing in record floods that wiped out entire communities in some of the poorest places in America. Kentucky's governor said 15 people have died, a toll he expected to grow as the rain keeps falling.

"We've still got a lot of searching to do," said Jerry Stacy, the emergency management director in Kentucky 's hard-hit Perry County. "We still have missing people."
