"South-east #Australia #marine #heatwave forecast to be literally off the scale - Patch of Tasman sea expected to warm over spring and summer to temperatures that risk significant losses to sea life

Australia’s south-east could be in for a marine heatwave that is literally off the scale, raising the prospect of significant losses in fishing and aquaculture.

The Bureau of Meteorology has forecast a patch of the Tasman Sea off Tasmania and Victoria could be at least 2.5C above average from September to February, and it could get hotter.

Oceanographer Grant Smith said the colour-coded scale the bureau uses to map forecast sea surface temperature anomalies stops at 2.5C. “We didn’t account for anomalies that high when we developed this ... it could be 3C, it could be 3.5C, but we can’t see how high it goes,” he said.
...
South-eastern Australia is a known climate change hotspot with its waters warming about four times faster than the global average."

"Record shattering: #Earth had its #hottest #July in 174 years -
Global sea surface temperature hit record high for 4th-consecutive month

Earth just roasted under its hottest July on record, according to scientists from NOAA’s National Centers for Environmental Information (NCEI). For the fourth-consecutive month, the global ocean surface temperature also hit a record high.

#Climate by the numbers - July 2023 - The average global surface temperature in July was 2.02 degrees F (1.12 degrees C) above average, ranking it as the warmest July in NOAA’s 174-year record. Because July is the globe’s warmest month of the year from a climatological perspective, July 2023 was also likely Earth’s warmest month on record.

July 2023 was the first time an average July temperature exceeded 1.8 degrees F (1.0 degree C) above the long-term average. Also of note, last month was 0.36 of a degree F (0.20 of a degree C) warmer than the previous July record from 2021. July 2023 marked the 47th-consecutive July and the 533rd-consecutive month with temperatures above the 20th-century average.

For the fourth-consecutive month, the global ocean surface temperature hit a record high as El Niño conditions that emerged in June continued into July. Globally, July 2023 set a record for the highest monthly sea surface temperature anomaly — which indicates how much warmer or cooler temperatures are from the long-term average — of any month in NOAA’s climate record, with an anomaly of 1.78 degrees F or 0.99 of a degree C. On July 13, NOAA’s Climate Prediction Center issued a statement announcing a greater than 95% chance that El Nino will continue through winter in the Northern Hemisphere.

"Is the #ClimateCrisis finally catching up with #Antarctica? Finding the answer has never been more pressing - Our inability to confidently predict sea level rise between an extremely challenging two metres and a civilisation-ending 10 metres is an exemplar of the problem facing researchers"

Andrew Meijers, Oceanographer with British Antarctic Survey, writes in today's #Guardian (07.08.2023); a compelling and chilling read.
...
"The global #climate is one hugely #complex interconnected system. While the #Antarctic and Southern Ocean are far removed from our daily lives, they play an oversized role in this system and the future climate that concerns humanity now. “Global warming” is really “ocean warming”. The atmospheric temperature change, the 1.5C Paris target we are now perilously near to exceeding, really is only a few percent of our total excess trapped heat. Almost all the rest is in the ocean and it is around Antarctica that it is predominantly taken up. How this uptake may change in the future as winds, temperatures and ice shift is a critical scientific, and human, question.
...
hese last few months have been a turbulent time to be an oceanographer, particularly one specialising in the vast Southern Ocean around Antarctica and its role in our climate. The media has been awash with stories of marine heatwaves across the northern hemisphere, the potential collapse of the Atlantic meridional overturning circulation by mid-century and the record-breaking deficit in Antarctic sea ice emerging this southern winter. Alongside heatwaves and bushfires in North America and southern Europe, flooding in China and South American winter temperatures above 38C, the climate has moved from a “future problem” to a “now problem” in the minds of many."
