Update: Power cut chaos in #Spain and #Portugal caused by 'rare' atmospheric phenomenon, says operator [#Heat related!]

"We're now hearing from Antonio Costa, president of the European Council, who says there are no indications that today's power outage has been caused by a cyber attack at this point."

"It says that "due to #ExtremeTemperature variations in the interior or Spain, there were anomalous oscillations in the very high voltage lines (400 KV), a phenomenon known as 'induced atmospheric vibration'"."

“Bleaching becomes more severe if either the #heat stress episodes are more intense or if they last for a longer time,” Joerg Wiedenmann, a marine biologist who heads the #CoralReef Lab at the University of Southampton in England, said….
The #Earth’s rising #temperatures have caused bleaching events to occur more often & last longer, he said. The changing & mixing of #ocean currents can also influence regional water temperatures, he added, further increasing the risk of bleaching.

“The ongoing global #CoralBleaching event is the biggest to date,” #NOAA scientists said.

Bleaching occurs when #heat upends the #coral’s metabolism, causing it to turn white as it expels the symbiotic algae that provide it with nutrients & color. Bleaching doesn’t mean the coral has died, but prolonged bleaching — which scientists say is made more frequent & severe by rising #sea #temperatures — can kill it.

Largest #coral bleaching event on record harms 84% of #global #reefs

Bleached coral dies when exposed to #heat stress for too long, threatening the bountiful #marine #ecosystem that depends on it for survival.

#CoralReefs around the world are losing their color at an unprecedented scale as a result of rising #sea #temperatures, marine scientists announced this week, w/ 84% of reefs exposed to bleaching levels of heat since 2023.

The Washington Post · Largest coral bleaching event on record harms 84 percent of global reefsBy Leo Sands

Spring evenings can be chilly. To warm the boat, a cast-iron stove burns briquettes, scooped in from the bucket at left and arranged using tongs.

Ashes fall through a grate into a drawer that gets emptied into an ash bucket.

On top, a fan gently pushes heat through the space. It runs on an electric current generated from the stove's heat.

Behind the stove are fireproof ceramic tiles that look like oak planks.
