The World Is Running Out of Male Sea Turtles – Science Alert
Green sea turtles are already an endangered species, mainly due to humans hunting them, harvesting their eggs, degrading their habitats, or entangling them in garbage of some kind. But they also face another, more insidious threat from people: the loss of male hatchlings from the species…that this is partly caused by rising temperatures due to climate change – but a new study has now unveiled another human-caused problem driving this trend. Certain pollutants may promote feminization in sea turtles, explains lead author Arthur Barraza, a toxicologist with the Australian Rivers Institute at Griffith University…
Earth Just Had the Hottest 12-Month Span in Recorded History – Scientific American
As this past October came to a close, it marked the hottest 12-month period ever recorded, a new analysis finds. This stark milestone is the latest in a string of superlatives to emerge this year that show how much carbon pollution has warmed the planet—and how that trend is accelerating. It also comes just weeks before international negotiators are set to meet and hash out issues around achieving the Paris climate accord’s fundamental goal: limiting global warming to no more than 1.5 degrees Celsius (2.7 degrees Fahrenheit) above preindustrial temperatures…

These Haunting Underwater Photos Portray Climate Change in a New Way – CNN Interactive
Akessa stares strait ahead with a look of fierce indignation. The 15-year-old is sitting in a rickety chair. Her hand are clasped in her lap. Her white skirt is billowing ever so slightly in what, at first glance, you might assume is the wind….There is no breeze blowing here. This girl and her searing gaze are underwater…
Research Confirms Link Between Snow Crab Decline and Marine Heatwave – NOAA Fisheries
“During the marine heatwave, snow crabs faced a triple threat,” said lead author and Alaska Fisheries Science Center stock assessment scientist Cody Szuwalski. “Their metabolism increased, so they needed more food; their habitat was reduced so there was less area to forage; and crabs caught in our survey weighed less than usual. These conditions likely set them up for the dramatic decline we saw in 2021…”
Climate crisis costing $16m an hour in extreme weather damage, study estimates – the Guardian
The damage caused by the climate crisis through extreme weather has cost $16m (£13m) an hour for the past 20 years, according to a new estimate.
Storms, floods, heatwaves and droughts have taken many lives and destroyed swathes of property in recent decades, with global heating making the events more frequent and intense. The study is the first to calculate a global figure for the increased costs directly attributable to human-caused global heating…
September shattered global heat record — and by a record margin – the Washington Post
Temperatures around the world last month were at levels closer to normal for July according to separate data analyses by European and Japanese climate scientists.
September’s average temperature was nearly 1 degree Celsius (1.7 degrees Fahrenheit) above 1991-2020 levels — or about 1.7 to 1.8 degrees Celsius (3.1 to 3.2 degrees Fahrenheit) above normal from before industrialization and the widespread use of fossil fuels…
Seaweed is mucking up beaches. This robot could stop it — and fight climate change – NPR
In shallow waters, sargassum can smother coral reefs and alter the water’s pH balance, killing off local seagrasses and mangroves. It can choke boat motors, constricting local fishing yields if not cutting off whole marinas. Sargassum once clogged a desalination plant so badly that residents of the U.S. Virgin Islands were told the drinking water may not be safe…
It’s Not Just Coral. Extreme Heat is Weakening Entire Marine Ecosystems in Florida – Grist Magazine
Anemones, sponges, and jellyfish are bleaching throughout the Everglades amid record temperatures. It’s a troubling sign for Florida Bay and beyond.
