For some reason our long climate proxies work for hundreds of years but always seem to stop working just before the man-made catastrophe appears. It seems to me that if a coral-tree-clam-sediment thermometer worked in 1393, it should work in 2020. It’s not like Earth has run out of trees, mud, pollen or corals.
So here we are again, this time with a new Fijian coral that runs 627 years continuously from 1380 to 1997. And the experts have to slap “an instrumental record” on for the last twenty years to find the catastrophe. The actual single coral core shows the water of Fiji was the same or even slightly warmer in the Medieval warm period as it was in the 1990s. There’s no sign at all, in 600 years of this coral, that man-made carbon dioxide has had any effect at all on the water around Fiji.
The new data comes from a coral core drilled in 1999, which explains why it suddenly stops. It does not explain why the world is about to end, but worried scientists waited 25 years to assess the coral core.
The apocalypse is upon us, but no one can find a new big coral to study it in real time?

Since the Pacific is a long way from Europe and Antarctica, we also confirm, yet again, that the Medieval Warm Period and the Little Ice Age were global events. Some force was warming the Earth 600+ years ago and the experts don’t know what it was. Then the Earth cooled, and the experts don’t know what caused that either, though the sun was suspiciously quiet, but we’re not supposed to mention that. The water around Fiji started warming in 1800AD, long before humans invented coal power or model T Fords.
The experts tell us this is a “significant departure” from natural variability, and the hottest in 600 years. But it’s only when they superimpose ocean buoys and other instruments that the “record” hottest ever temperature appears like magic at the end.

Despite the authors forgetting to label the instrument data in the key on the graph, the caption contains the fine print “Also shown is the most recent SST data for Fiji from ERSSTv5 (1998 to 2021) shown in (E) (black).” So the only data for the “record” spike in the last 20 years of corals, comes from thermometers (and statistical infilling) instead. Wouldn’t you know?
So yet again, even though I hear there is still coral living around Fiji, the key hottest ever record part of the graph is not from that coral.
I’ve been asking for years for a long proxy to show we have a crisis. One solitary proxy that assesses temperatures in 2020 as well as it did in 1703 or 1492. Does anyone know one?
If corals and clams work so well as thermometers do, surely Australia, with the worlds largest living reef, ought to have hundreds of old corals we can study? You’d think if our climate scientists cared about the climate and were given, say, $440 million dollars to spend, they could have found some? But perhaps they have to leave them in drawers for 20 years so they have room to tack on the instrumental spikes at the end?
And here are lots more graphs from the paper showing that CO2 has made no difference to the climate. A is the Southwest Pacific. B is the Macassar Strait, D is from Palmyra, E is the central pacific, F is the Galapagos, and none of them show anything we should spend a trillion dollars on.

The propaganda from Phys Org:
Fijian coral reveals new 627-year record of Pacific Ocean climate
An international team of climate scientists have used a 627-year coral record from Fiji to reveal unprecedented insights into ocean temperatures and climate variability across the Pacific Ocean since 1370.
It’s not even phrased as a link or association, it’s so weak it’s an “interaction”:
The study published in Science Advances, co-authored by Dr. Ariaan Purich from Monash University and Professor Matthew England and Dr. Rishav Goyal from UNSW, shows how human-caused climate change is interacting with long-term patterns of climate variability in the Pacific
Follow the long tenuous wandering path to “human derived” blah:
The new coral record shows that the local ocean temperature was warm between 1380 and 1553, comparable to the late 20th and early 21st centuries. However, when combined with other coral records, the Pacific-wide warming observed since 1920, largely attributed to human-derived emissions, marks a significant departure from the natural variability recorded in earlier centuries.
No. The coral record does NOT show this:
The record also shows that present ocean temperature is the highest for the past 653 years.
And there are no implications for millions of people either, other than we should stop wasting money immediately:
The work provides new insights to understand how climate trends are leading to shifts in weather patterns and more extreme weather events that will have significant implications for millions of people living in the Indo-Pacific region.osystems across the vulnerable Pacific Island nations.”
The money line comes next– the whole point of gouging a hole in a 600 year old coral is to advertise the renewable industry and justify trillion dollar government policy mistakes. What is a line like this doing in a press release of a scientific coral study?
The study provides further motivation for the global community to keep working towards limiting warming to 1.5ºC by developing renewable energy resources at scale, to electrify the economy and phase out coal and gas.
Government funded scientists have become prostitutes for Big Government. I would love to be proved wrong. But we all know that no government funded professors could dare criticize this study.
Thanks to all the supporters who help fund me so I can.
