Sixty percent of all human CO2 emissions have been emitted since 1985 but today the corals are healthier than ever
In 1985 humans were emitting only 19.6 billion tons of CO2 each year, and now we emit 37 billion tons. In the meantime AIMS have been dragging divers thousands of kilometers over the reefs to inspect the coral cover. These are the most detailed underwater surveys on the largest reef system in the world, and they show that far from being bleached to hell, the corals are more abundant than we have ever seen them.
As Peter Ridd points out, when the reef was doing badly, AIMS was happy to combine the data on the whole reef, so we could lament its demise. But lately AIMS splits it into separate sections and if Peter Ridd didn’t check the numbers, who would know it was a record across the full 2,300 kilometer length of the reef? And that may be exactly the point. As Ridd reminds us, in 2012 the AIMS team predicted the coral cover in the central and southern regions would decline to 5 – 10 percent cover by 2022. Instead the whole reef is […]

A little tiny delated backdown from extreme climate hype begins
In 2018, a study of aerial photos of 700 Pacific Islands showed that 89% were the same size or growing. This rather destroyed the idea that sea levels were swallowing small nations. The New York Times said nothing. Indeed, the only Pacific things shrinking were deserted sand drifts. No islands bigger than 10 hectares were getting smaller. Measured in square kilometers that’s “0.1”. Despite the media headlines and delegations from Kiribati and Tuvulu begging for money to hold back the tide, no islands with people living on them were shrinking. None, not one island in the Pacific big enough to matter, was disappearing. The largest 630 islands in the Pacific had not being touched by climate change for decades.
In 2023 another study of 1,100 islands came to the same conclusion. To find that many islands they included things as small as one thousandth of a square kilometer — we’re talking about spits of sand 10 meters square. (There are whales larger than that.) The Kench team studied islands in the Indian Ocean too. In one case, they sliced, diced and drilled through one poor island […]

43% fewer cyclones is a good thing, right?
Using the same ClimateChangeTM reasoning the UN Secretary General uses, it’s clear fossil fuel use dramatically reduces the number of dangerous cyclones in the Northern Indian Ocean. A new study revealed an astonishing 43% decline in the number of equatorial cyclones in recent decades (1981–2010) compared to earlier (1951–1980) when fossil fuel use was vastly reduced. The researchers also point out that this is especially interesting because “the Indian Ocean basin has warmed consistently and more than any other ocean basin.” Could it be that warmer oceans are not necessarily terrible?
The study looked at the Low-Latitude Cyclones (LLC) that originate near the equator in the North Western Indian ocean. These LLC’s are smaller but intensify more rapidly than other cyclones, giving people less time to prepare. In 2017 LLC Ockhi caught forecasters off guard, travelled 2,000 kilometers and caused the deaths of 884 people in Sri Lanka and India.
This is obviously a benefit for the billion poor people who live around the Bay of Bengal. The researchers however, for some reason do not call for an increase in fossil fuel emissions. Instead they looked for and found […]
Scott Manley has done an excellent summary video of the Tongan volcano, much of the science and history of it as well as the effects thousands of miles away. The area around the volcano had completely reformed in the last ten years. He has collected some great footage together.
It’s interesting watching air pressure waves travel across Japan and the USA. Ken Stewart found the compression- decompression wave hit the east coast of Australia at about 5:16 Qld time and took 3 hours and 24 minutes roughly to get to Shark Bay, an average speed of about 1,160 kph. The decompression was about half an hour after the first peak and can be seen (still) in weather station pressure data.
Eruptions of Hunga Tonga-Hunga Ha’apai are roughly 900 years apart and this one was on schedule.

The CliffMass weather blog noted that the pressure wave hit Seattle at 4:30AM local time, so the air pressure spike took 8.5 hours to cross the Pacific at about 664miles per hour. h/t WattsUp

It’s a Nightmare on Crab Street
Crabs are being drawn to high electromagnetic (EMF) fields around undersea cables and getting trapped there for hours, “mesmerized”.
They are not just immobilized, in lab tests it screws up their blood chemistry and circadian rhythm too.
Nature-lovers might wonder what other marine life is also being impacted? What if the magnetic fields are playing havoc with migrating fish and turtles too? It might be handy to find that out before we build bigger taller towers offshore with bigger stronger cables.
Where is the Green outcry, or the Save-the-crabs campaign? Perhaps some kinds of pollution are OK “for the greater good”?
These are not some esoteric rare crustaceans, by the way, but common dinner crabs — the ones food chains and fisheries depend on.
If these crabs were victims of coal plants the headlines would be a catastrophe.
Underwater power cables are ‘mesmerizing’ crabs around Scotland
In a new study, researchers found brown crabs ‘freeze’ when they come too close to the electromagnetic fields generated by these cables. This disturbing behavior may negatively affect the marine creature’s […]
“Clark et al. (2020) found 100% replication failure. None of the findings of the original eight studies were found to be correct.”
Scientists tried to repeat eight experiments that showed “acidification” would make reef fish get hyper, act like their predators smell nice, and generally swim in the wrong circles, behave weirdly and need therapy sessions. Turns out the fish will be OK, but James Cook Uni’s reputation may never recover. The original junk experiments and press releases came out of the coral reef centre at JCU.
This is the “replication crisis” Peter Ridd warned us about. He was fired from JCU in 2018 after stating that work from JCU’s coral reef centre (ARCCoE) was not trustworthy. He also helped expose manipulated photos of reef fish. Obviously this latest reef research shows he was right to be concerned about quality assurance at JCU. One JCU researcher, Oona Lönnstedt, had already been caught fabricating data in Sweden, and yet JCU “investigated” and sacked Ridd faster than it investigated her suspicious lionfish shots. Indeed, two years on, JCU has not even officially appointed the committee to investigate her potentially fraudulent work. It seems JCU would rather employ untrustworthy scientists than […]
This should end all the Pacific Island climate claims right here. A new study of over 700 islands for decades shows that even though seas are rising faster than any time in the last million years, somehow no islands with people on are shrinking. This means there are no climate change refugees from any vanishing island. Plus it’s more proof that highly adjusted satellite data is recording sea levels on some other planet.
Over the past decades, atoll islands exhibited no widespread sign of physical destabilization in the face of sea-level rise. A reanalysis of available data, which cover 30 Pacific and Indian Ocean atolls including 709 islands, reveals that no atoll lost land area and that 88.6% of islands were either stable or increased in area, while only 11.4% contracted.
Look how closely these researchers are tracking the shores. Below on Tuamoto, French Polynesia, scientists can tell you that islets 12 and 14 (see pic) have disappeared since 1962. So we can track roving blobs of sand about 20 to 30 meters across.

Ever wondered how the whole planet could suddenly “get warmer” during an El Nino, and then suddenly cool again? William Kininmonth has the answer. As I read his words I’m picturing a major pool of stored “coldness” (bear with me, I know cold is just a lack of heat) which is periodically unleashed on the surface temperatures. The vast deep ocean abyss is filled with salty and near freezing water. In years where this colder pool is kept in place we have El Ninos, and on years when the colder water rises and mixes up near the surface we have La Ninas. The satellites recording temperatures at the surface of the ocean are picking up the warmth (or lack of) on this top-most layer. That’s why it can be bitterly cold for land thermometers but at the same time the satellites are recording a higher world average temperature, due to the massive area of the Pacific.
In other words, just as you’d expect, the actual temperature of the whole planetary mass is not rising and falling within months, instead, at times the oceans swallow the heat on the surface and give up some “coldness”. At other times, the cold […]
