But what’s clear, she said, is “that current sea surface temperatures are exceptionally and unseasonably warm” and bringing wide-ranging implications, “especially for complex ecosystems such as coral reefs.”Gregory C. Johnson, an oceanographer at NOAA, said sea surface temperatures have soared this year. Surface temperatures tend to remain high from August through to September before starting to decline, said Johnson. “There’s still room to have warmer sea surface temperatures” this year. In the Florida Keys, a marine heat wave has pushed ocean temperatures to record-breaking, “hot tub” levels, leaving multiple coral reefs now completely bleached or dead. Some scientists are concerned that the ocean temperature records set this year could mark the start of an alarming trend for ocean heat.

☆ The planet's coldest, saltiest ocean waters are heating up and shrinking, new report finds
▼ + stars: | 2023-06-12 | by ( Laura Paddison | ) edition.cnn.com time to read: +4 min

CNN —Deep ocean water in the Antarctic is heating up and shrinking, with potentially far-reaching consequences for climate change and deep ocean ecosystems, according to a report. They also found that ocean waters deeper than 2,000 meters (6,600 feet) have warmed four times faster than the rest of the global ocean. They are a vital part of global ocean circulation, transporting human-caused carbon pollution into the deep ocean where it remains for centuries, said Silvano. If this deep circulation weakens, “less carbon can be absorbed by the deep ocean, limiting the ability of the ocean to mitigate global warming,” Silvano told CNN. This cold, dense water also has a vital role in supplying oxygen to deep ocean waters.

☆ I lived and worked in Antarctica for 5 months without WiFi or running water. It didn't feel as remote as I expected.

Lucy Bruzzone is one of several women who spent the last five months working in Antarctica. Bruzzone found it surprisingly easy to adjust to life on the peninsula and said it didn't feel as remote as she expected. Historically, Antarctica has been an extremely male-dominated place; Port Lockroy didn't have its first female team member until 2001. The team spent five months in Antarctica through the UK Antarctic Heritage Trust. Between ship visits, we'd grab a quick lunch, restock the shop, cancel stamps on any postcards we'd received, and monitor the penguins on alternate days.

☆ Ocean temperatures are off the charts right now, and scientists are alarmed

CNN —Ocean surface heat is at record-breaking levels. Since La Niña ended in March, ocean temperatures seem to be on a rebound, scientists say. Worrying impacts of ocean warmingWhatever the reasons behind the increase in ocean heat, the impacts are potentially catastrophic if temperatures continue to head off the charts. For now, ocean surface temperatures have started to fall, even if they remain high for this time of year. As scientists continue to analyze the reasons for record ocean warming, they are clear records will continue to be smashed as the climate crisis intensifies.

☆ Map shows the ice sheets and glaciers melting that scientists most fear will be the source of catastrophic rising sea levels

Melting ice that could tip sea level rise into catastrophic levelsSource: NASA Ice ViewerChart: Annie Fu/InsiderWhile it's easier to plan for a steady sea level rise, scientists are very concerned about what would happen if huge chunks of ice collapse and abruptly change sea levels. The Antarctic ice sheet is much bigger than the ice sheet on Greenland. If they were to melt totally, the Greenland ice sheet would contribute about 23 ft to the sea levels, while the Antarctic ice sheet holds enough ice to raise sea levels by 58 feet. Local sea level variationGlobal mean sea level rise is only a snapshot of the whole picture. Because sea levels are influenced by the local environment, the sea level rise can be much higher locally than it is on a global scale.

☆ Fact Check-The Earth is not covered by a dome or ‘firmament’

Users on social media are saying people on Earth are living under a dome, also called a “firmament,” without providing evidence to support the claim. But the video’s examples offer no proof of humans living under a dome or firmament, while there is ample evidence that no dome exists. “Rocket hitting the flat earth dome”, reads the title of one of the YouTube clips. SIXTY YEARS OF SPACEFLIGHTExperts pointed out that if there were a dome that covered the Earth, astronauts would have encountered it by now. A video provides no evidence that the Earth is under a dome or “firmament”.

How do we weigh the risks of underreacting to climate change against the risks of overreacting to it? While he’s not an expert on climate change, he has spent decades thinking deeply about every manner of risk. That’s particularly true if climate change is akin to cancer — manageable or curable in its earlier stages, disastrous in its later ones. Maybe, I realized, in assessing my newfound concerns about climate change, my long-held beliefs might provide a solution — look to the market.

☆ 'Doomsday' glacier — which could raise sea levels by several feet if melted — is 'holding on by its fingernails' says new study

A body of ice known as the "Doomsday Glacier" could melt faster than predicted, a new study says. The Thwaites Glacier protects the West Antarctic ice sheet, and researchers watch it closely. The melting of the Thwaites Glacier — which is around the size of Florida — could raise sea levels by up to two feet.

Prin comparaţie, insula Mallorca – o importantă destinaţie turistică a Spaniei, aflată în Marea Mediterană – are o suprafaţă de 3 640 de kilometri pătraţi. Statul american Rhode Island este şi mai mic în raport cu aisbergul A-76, având o suprafaţă de 2 678 de kilometri pătraţi. Cum a fost detectatA-76 a fost detectat în premieră de British Antarctic Survey şi confirmat de National Ice Center din statul american Maryland, folosind imaginile captate de misiunea Sentinel-1, lansată în cadrul programului spaţial Copernicus şi care constă în doi sateliţi cu orbite polare.

☆ Un iceberg uriaș riscă să se ciocnească cu o insulă pe care trăiesc milioane de pinguini

Insula South Georgia, teritoriu al Regatului Unit, este un fost avanpost de vânătoare de balene, devenit zonă marină protejată. Acum, un iceberg de 3.900 de kilometri pătrați, care cântărește sute de miliarde de tone metrice, amenință acest ecosistm. Cu doar 200 de metri adâncime, este relativ subțire pentru un iceberg de mărimea sa, ceea ce crește probabilitatea de fragmentare, spun oamenii de știință. În aceste condiții, A68a riscă să se ciocnească de insulă, unde ar putea afecta viața milioanelor de pinguini, scrie digi24.ro. Avem mai degrabă o abordare de tip „Star Trek” - suntem interesați să studiem efectele”, spune el.

☆ Un aisberg gigantic, pe traiectoria de coliziune cu o insulă din Atlanticul de Sud, lângă o colonie de pinguini

Un aisberg gigantic se îndreaptă spre insula Georgia de Sud din Atlanticul de Sud, iar oamenii de ştiinţă se tem că posibila coliziune ar devasta fauna şi flora, afectând inclusiv pinguinii, focile şi albatroşii care trăiesc pe insulă, informează Reuters. Aisbergul gigantic - denumit A68a - se află pe o traiectorie de coliziune cu insula Georgia de Sud, un teritoriul britanic de peste mări din largul Americii de Sud. Nu se ştie cu siguranţă dacă se va produce o coliziune, întrucât curenţii ar putea îndepărta aisbergul de insulă, a mai spus Tarling. ''Curenţii din vecinătatea insulei sunt complecşi şi există încă probabilitatea de a rata insula'', a mai spus Tarling. A68a ar putea totodată să fie un obstacol pentru ambarcaţiunile guvernamentale care supraveghează activităţile de pescuit din vecinătatea insula Georgia de Sud şi a insulelor Sandwich de Sud, au mai precizat autorităţile britanice.
