No. Not a big worry at all. Fake news dressed up as alarmism from the heavily discredited BOM.

Of course the corals should be the sub-surface temperatures, not SST.

Of course the corals should be the sub-surface temperatures, not SST.

"Sea surface temperature (SST) is the water temperature close to the ocean's surface. The exact meaning of surface varies according to the measurement method used, but it is between 1 millimetre (0.04 in) and 20 metres (70 ft) below the sea surface."

So you see it is a true measure of Sea SURFACE Temperature and shouldn't be used to justify bleaching.

No cyclones on the horizon to relieve the Great Barrier Reef from coral bleaching

THE weather needed to cool down the Great Barrier Reef to prevent further coral bleaching appears to be staying well away from the Far North.

The Bureau of Meteorology says sea temperatures that have caused coral bleaching in several tourism hot spots ­between Cairns and Townsville are likely to rise in coming days, potentially worsening the natural phenomenon.

It is the second summer in a row the Reef has undergone a mass bleaching event, which could result in large-scale coral dieback.

Global warming will result in more cyclones on average, but that doesn't mean there is going to be one every day

Global warming will result in more cyclones on average,

So you are happy to use satellite data when it supports your argument, but when it doesn't, it becomes "unreliable"
You are happy to use wikipedia in post #12 but if wiki is used to show you are wrong then it is "unreliable"
You are happy to use data from JoNova and whatsupwiththat but anything from Skeptical Science is "unreliable".

So it is one set of rules for you and a different set of rules for anyone else.
A particularly dishonest form of debating and I really don't know what you are trying to prove. It's not as if Ozpolitics is going to change the world.

Do you agree the globe is warming now? A simople ‘yes’ will do.

Is that a “yes” Lees?

The BuMet has reported the land and the seas around Australia have warmed by 1°C, land since 1910.

Scientific instruments can measure Angstroms, fractions of a degree are easy.

Clutching at straws again.

So you don't dispute that you are a particularly dishonest debater.

So it measures the SST to a maximum depth of about 1/50th of a millimeter. And yet you are confident that is a realistic estimation of depths to 20 Metres.

As explained before coral bleaching can occur due to sudden changes in temperature both up and down. It does not need to be high temperatures.

When researchers dove into the South China Sea to find out what one of the strongest El Niño effect on record was doing to the sea’s reefs, they found that nearly two-fifths of the coral had died in just six weeks.

The culprit is believed to be the extreme overheating of the water. At the Dongsha Atoll, roughly halfway between Hong Kong and the Philippines and the site where the coral damage was observed, researchers recorded temperatures 6 degrees Celsius warmer than average for that time of year.

Their findings were published Thursday in Nature’s Scientific Reports journal.

Reefs such as those at Dongsha Atoll constitute one of the most vulnerable ecosystems in the world, according to Thomas DeCarlo, one of the study’s researchers at Massachusetts-based Woods Hole Oceanographic Institution.

When coral is subjected to unusual temperatures, it expels the algae that live on it, and which give the reefs their vivid colors. This usually turns the coral completely white — a sign it is dying or dead, and a phenomenon often referred to as “coral bleaching.” Even when conditions revert to normal, it takes decades for the coral to recover. “If there are repeated thermal stress events before the time needed for recovery, the coral could continue to decline,” DeCarlo told Sixth Tone.

Researchers found that the mean temperature in the South China Sea was 2 degrees higher during the summer of 2015, when their study was carried out. But at Dongsha, the huge crescent-shaped coral reef experienced an anomalous high-pressure system that created weak winds and smaller waves, conditions that contributed to raising water temperatures by up to an additional 4 degrees.

Created by the El Nino and a high pressure system. What a maroon.

So you see it is a true measure of Sea SURFACE Temperature and shouldn't be used to justify bleaching.

That is correct, Lees.

It can be 40°C on the surface and 10°C a couple of metres below that

i can see you have been to the beach and walked in and then hit a cold spot. However where did  the ocean the ocean get to 40ºC?

Nah, trying to get away from heat bleaching corals you came up with weird irrelevant crap.'

Were you? My notes would have said “What a load of cobblers!”


There was a pun buried in all that!

No.
