#bleaching

Old #rain magic, tested for you: People used to say ‘If I lay out #laundry to #bleach now, the missed rain will come after all!’ I washed white clothes and hung them up. Now they're getting wet again. Yeah! 🌧️

Traditional #bleaching: On sunny days, people laid down wet white laundry on grass, and waited that the sun did its work tashamillergriffith.com/2012/0 (never use chlorine bleach if you want to keep the fabrics for a long time. It has a somewhat corrosive effect

Tasha Miller Griffith · Sun Bleaching – Yup, It Still Works  One of the things I love about having this blog is that it encourages me to do my homework.  I know that I hang clothes out in the sun to bleach them, and that it works, but what’s the…

Over 97 Percent Of Bleached Coral Died At Lizard Island Reef After This Year's Event

The #GreatBarrierReef was struck by an extremely harsh mass #bleaching event this year, and it looks like parts of the reef are struggling to bounce back. Drone imagery of #LizardIsland’s North Point Reef shows that 97 percent of the bleached coral has died since the event earlier this year.

#ClimateCrisis: NOAA confirms fourth global #CoralBleaching event phys.org/news/2024-04-noaa-fou

"The world is currently experiencing a global coral #bleaching event, according to #NOAA #scientists. This is the fourth global event on record and the second in the last 10 years... As the world's #oceans continue to warm, #coral bleaching is becoming more frequent and severe. When these events are sufficiently severe or prolonged, they can cause coral mortality"

The Widest-Ever Global #Coral Crisis Will Hit Within Weeks
Rising sea temperatures around planet have caused #bleaching event that is expected to be most extensive on record. It is fourth such global event on record and is expected to affect more reefs than any other. Bleaching occurs when #corals become so stressed they lose symbiotic algae they need to survive. Corals can recover, but if water surrounding them is too hot for too long, they die.

The New York Times · Scientists Predict Most Extensive Coral Bleaching Event on RecordBy Catrin Einhorn

"#Coral research finds bleaching impedes reproduction and hinders recovery

#Bleaching can suppress reproduction in a common coral species found in the Great Barrier Reef, hampering future reef replenishment, new research led by the Australian Institute of Marine Science (AIMS) and James Cook University (JCU) has identified."

Many #CoralReefs are dying. This one is exploding with life.

Scientists recently observed a rare phenomenon on a reef in #Cambodia that left them in awe — and filled them with hope.

"Globally, coral reefs, which underpin commercial fisheries and protect coastlines from storms, have declined by half since the 1950s, largely due to #ClimateChange. Spells of extreme #MarineHeat break down the relationship between #coral and a type of symbiotic #algae that gives it both food and its vibrant colors. The coral turns white — a process referred to as #bleaching — and can then easily starve to death.

"The reefs in Cambodia and in the broader #EastAsian region, however, appear to be bucking this trend. Surveys indicate that they haven’t declined in recent decades, perhaps because they’re more resilient to warming. Their secret to survival may ultimately help safeguard ailing reefs elsewhere."
