Peter Boyer seems to think Myron Ebell owes him an apology, but it’s the other way around. And Boyer ought say sorry to his readers.
“Science Communication” is a pretty dismal, immature profession. It’s so bad that an award-winning science communicator can talk about “blunt denial” even while denying basic tenets of logic and appearing to have done almost no research on the global warming debate. If he was ever taught the basics of reasoning, like “correlation is not causation” or “all models are wrong but some are useful,” he’s long forgotten them. What’s an Order of Australia worth these days? Apparently not much.
If he had the open mind he talks about, he might have bothered to read the skeptical sites before he wrote an article. We’d have provided all the evidence an open mind could need to know that Myron Ebell is right on the money. So here Peter, with all due respect, is the red pill — the stuff the UNSW profs of climate crisis won’t tell you even if you dared to ask them.

1954 Yearbook Brisbane
Here’s an update to the digging through our historic records we discussed a month ago, we can now include nearly twice the stations and the difference between temperatures originally recorded 100 years ago and temperatures today are even smaller.
Chris Gillham has been working with CSIR documents and official Commonwealth Year Books. Last month he used the 1953 Year Book which contained 44 weather station averages for 1911-40 to compare with 2000-14 temperatures, but has since discovered that the 1954 Year Book provides an additional 40 stations with 1911-40 data. The average rise in mean temperatures across all 84 weather stations around Australia over the last 70 years of global warming is about 0.3C. This larger dataset suggests as much as two thirds of the current official trend in Australian warming was due to post hoc adjustments, not heat recorded by thermometers.
These historic temperatures were calculated by the best scientists of the day, using the best equipment of the era (the same Stevenson Screen we use now). Yet again, global warming appears to have a “man-made” contribution. Far more important than CO2 is man-made “pollution” called homogenisation.
When doubling the recorded trend makes “No difference”
Yet more evidence that there is no relationship between CO2 and cyclones, hurricanes, and typhoons. This paper from 2012 tests the theory that global warming made storms more severe and tried to find any effect on typhoons hitting Japan that could be linked to climate change since 1980.
There has been no increase in “super typhoons”. The typhoon season is not longer, nor is it delayed in starting. There has been no change in intensity. The wind speeds are not increasing. The minimum pressure is pretty much the same.
CO2 appears to influence storms in simulated worlds, but not so much in the real one. There is no sign of more severe storms in Australia, New Zealand or the South Pacific either. Nor is there any pattern in the Global Energy indicies, US Hurricanes, US Tornadoes either.
When will scientists and reporters make sure that their audiences know that?
The authors conclude:
“The results suggest that typhoons have not been influenced by global warming. In conclusion, global warming has not significantly changed the characteristics of typhoons, and there is no close relationship between the two.”

When it comes to our rare high-quality historic records, and the real long term trends of Australian weather, the silence is striking. There are some excellent historical records of long term temperature data from the late 1800s in Australia, which lie underused and largely ignored by the BOM.
For the BOM, history almost appears to start in 1910, yet the modern type of Stevenson screen thermometer was installed across Australia starting as early as 1884 in Adelaide. Most stations in Queensland were converted as long ago as 1889 and in South Australia by 1892. Though states like NSW and Victoria were delayed until 1908.
Here’s a photo of the ones in Brisbane in 1890.
Brisbane was recording temperatures with modern Stevenson screens in 1890, as were some other stations, but the BOM often ignores these long records.
The BOM don’t often mention all their older temperature data. They argue that all the recordings then were not taken with standardized equipment. The BOM prefers to start long term graphs and trends from 1910 (except when they start in 1950 or 1970, or 1993).
The BOM was set up in 1908. Before that there were Stevenson screens going in [...]
Skeptics, and particularly Nils-Axel Mörner have been saying that sea level rise, as recorded by tide gauges has been much slower than widely advertised. They’ve also pointed out how the rates of sea-level rise have either stayed the same or slowed down. There’s been no sign of the acceleration needed for the wildly speculative hypothesis that your SUV, and China’s coal plants are warming the ocean.
This week a new Nature paper (Hay et al) shows the skeptics were right — but did that view make it to any news broadcast?
Watch the sea-level scare mutate
Even in The Australian the spin from the propaganda machine gets a running, and the previous slow rise is used to pump the scare that the modern “acceleration” is even scarier. What the Australian (and selected sea level “experts”) don’t mention is that the tide-gauges don’t show any acceleration, and nor did the raw recordings from satellites. The 3mm rising sea claims apparently come from satellites that were calibrated to one subsiding tide gauge in Hong Kong.
It’s cherry picking par excellence. We might finally accept tide gauges up to 1990, but after that the tide gauges don’t count — bring in the “adjusted” [...]
A new study of Law Dome Ice cores tells us that droughts are common in Australia, and that there appears to be eight mega-droughts over the last thousand years, including one that lasted a whopping 39 years from 1174- 1212AD. By their reckoning the 12th Century in Australia was a shocker with 80% of it spent in drought conditions. Things weren’t so bad from 1260 – 1860, at least, as far as they can tell. The researchers are convinced theirs is the first millennial-length Australian drought record. It does seem significant.
The researchers, sensibly, think we might want to pay attention to the Pacific cycles and store a bit more water. Without fanfare the paper also suggests that droughts were worse in medieval times.
“this work suggests Australia may also have experienced mega-droughts during the Medieval period that have no modern analog. Therefore, management of water infrastructure in eastern Australia needs to account for decadal-scale droughts being a normal feature of the hydrological cycle.”

The ABC reported this largely as a water management story, without asking whether their past stories that blamed CO2 for droughts were less likely to be true. [...]
As I’ve repeatedly posted this year, there is a strange coincidence between geothermal activity and warming in Antarctica. We are still discovering volcanoes underwater, so we can’t pretend we have accurate data on their contribution in joules or the trends in that. On Antarctica almost all the headlines of doom and collapse come from West Antarctic peninsula or the ice sheet nearby which also happen to be over the West Antarctic Rift System. Most other places in and around Antarctica are cooling or staying the same, and sea ice is hitting record levels. “Must be CO2 then.” ; -)
Damiani et al looked at the crustal thickness beneath Thwaites Glacier, and finds it is quite thin, like that beneath the Pine Island Glacier. The researchers conclude that it is likely there is a major volcanic dome in Marie Byrd Land.
Spot any media mention of the possibility that hot lava might be to blame instead of your SUV. Good little propaganda writers produce plenty of gloom and doom headlines of the imminent collapse of ice-sheets. Where are the journalists? For that matter — which climate scientist tries to make sure journalists present an accurate report?

Two papers on ocean heat released together today. The first says the missing heat is not in the deep ocean abyss below 2000m. The second finds the missing heat in missing data in the Southern Hemisphere instead. Toss out one excuse, move to another.
The first paper by Llovel and Willis et al, looked at the total sea-level rise as measured by adjusted satellites*, then removed the part of that rise due to expanding warming oceans above 2,000 m and the part due to ice melting off glaciers and ice-sheets.** The upshot is that the bottom half of the ocean is apparently not warming — there was nothing much left for the deep oceans to do. This result comes from Argo buoy data which went into full operation in 2005. (Before Argo the uncertainties in ocean temperature measurements massively outweigh the expected temperature changes, so the “data” is pretty useless.)
Figure 2 | Global mean steric sea-level change contributions from different layers of the ocean. 0–2,000m (red), 0–700m (green), 700–2,000m (blue). The dashed black curve shows an estimate for the remainder of the ocean below 2,000m computed by removing the 0–2,000m estimate from the GRACE-corrected observed mean sea-level time series. [...]
This new paper by Adophi et al uses beryllium, oxygen and carbon isotopes from Greenland ice cores right back as far as the depth of the last ice age, 22,500 years ago, and finds there is a link between solar activity and the climate. It follows these proxies of temperature and solar activity as the planet warmed to the start of the Holocene 10,000 years ago.
It is gaining attention in The Daily Mail, with the headline:
Is the SUN driving climate change? Solar activity – ‘and not just humans’ – could be increasing global warming, study claims
During the last glacial maximum, Sweden was covered in a thick ice sheet that stretched all the way down to northern Germany and sea levels were more than 330ft (100m) lower than they are today, because the water was frozen in the extensive ice caps.
‘The study shows an unexpected link between solar activity and climate change,’ Dr Muscheler said in a press release.
‘It shows both that changes in solar activity are nothing new and that solar activity influences the climate, especially on a regional level.

Who would have thought? Antarctic volcanoes are hot after all. Having a volcano under an icesheet makes a difference, and some of the sea level rise blamed on CO2 is more likely to be because 1,000 °C lava is not far from sub-zero ice. Right now, according to scientist Dustin Schroeder and co, it is as if the Thwaites Glacier in West Antarctic is sitting on a “stovetop burner”.
Only last week I wondered if West Antarctic volcanoes had something to do with the Antarctic warming and pointed out this strange coincidence below where almost all the warming seems to occur over the volcanic area which is part of the hot “Pacific rim of fire”. I also wondered why some parts of the media don’t seem to mention the volcanoes. Wait and see if this story gets picked up. So far, Fox, and Business Insider have it.
“Using radar data from satellites in orbit, the researchers were able to figure out where these subglacial streams were too full to be explained by flow from upstream. The swollen streams revealed spots of unusually high melt, Schroeder said. Next, the researchers checked out the subglacial geology in the region and found that fast-melting [...]
