I find the remark about "rent an expert" offensive. Not everyone can be bought, by a long shot. I consider myself relatively expert in lv and mv grid protection systems having worked in this area for 20 years up to my recent retirement, though others may disagree. I will not be bought short of someone putting a gun to my head, for any amount. I do not claim to be a particularly virtuous person, just a person with integrity, along with many shortcomings.
Data shows there’s no climate catastrophe looming – climatologist Dr J Christy debunks the narrative
Quote from: championoftruth on 20/12/2022 16:26:02Data shows there’s no climate catastrophe looming – climatologist Dr J Christy debunks the narrativeThat's a pity, as there has been one every 150,000 years and the next one is due right about now. Assuming, of course, that we are talking about a "hot catastrophe". The more spectacular ones are the ice ages, which occur about 100,000 years later.The current consensus "anthropogenic CO2" narrative is obviously bunk but the facts all point to a repeat of previous climate cycles - and why not?
Dr John Christy’s research has consistently shown that the atmosphere is warming at a much slower rate than what the climate models predict.
Far too few people do anything about what is actually happening.
All the more reason to stop spending public money on worthless models and start addressing the inevitable.
So far, they seem to have had no effect beyond increasing CO2 levels
In the absence of climate models there would be nothing to talk about at COP pissups. Nobody can argue with the facts, only about how to interpret them and who to blame, and you need a model for that. So that's at least 80,000 additional passenger flights per year for the delegates, plus whatever fuel is expended on armed presidential motorcades, whatever it takes to get the protestors and TV crews there and back again, and the entire spurious industry behind it all. The net output directly attributable to COP and the activities of IPCC (more travel, and a fair bit of diesel, gasoline and JETA1 expended in Arctic "research") since 1988 has been hot air. At your expense.
(Please note that, in general, the people who fly to conferences will do that regardless of the topic and that those who want to play with computers will model something as a test case.)
, they might spend their precious time and your money on something useful.

So which is it? Is it warming, albeit it slower than predicted by climate models, or is it not warming at all?
It's likely that actual measurements have been reported honestly, and it is bloody obvious that the earth's atmosphere has warmed in the last 200 years. However there is plenty of room for doubt about the meaning of much 20th century data, and the validity of extrapolation from earlier measurements. A lot also depends on the timescale you choose.We are currently in a major upswing that began about 15,000 years ago at the end of the last ice age. Geological precedent suggests this will turn over within the next 500 years and slide slowly down for the next 100,000 years. The total excursion is around 12°C.Witin that broad sawtooth are all sorts of short-term fluctuations. As far as the British Isles are concerned, and probably much of the northern quarter of the globe, the present annual mean temperature is about the same as in the Roman period, say 1500 years ago. The sudden appearance of chimneys and structured fireplaces in 12-13th century European architecture indicates a rapid decline and slow recovery until the 19th century, by which time we were acquiring credible instrumental temperature records.Problem is that most of the records are from the inhabited areas, which still only account for about 5% of the total, or from a few shipping routes, mostly in the north Atlantic. Any statement about the surface temperature of the middle of the Pacific in, say, January 1800, is pure guesswork, and nobody had taken a thermometer to the poles before 1914.There was a rapid expansion of very accurate data from 1910 to 1950 because surface temperature is critical to aviation. Airports measure and broadcast surface temperature to ± 0.5°C every 20 minutes and report to a central meteorological service every 4 hours. But from 1950 onwards the number of active airfields decreased and the remainder tended to be concrete or tarmac and close to cities, so inevitably hotter than the surrounding countryside. Satellite surveillance gives us credibly comparable data for the entire globe, but much historic surface data was "adjusted" after 1970 to coincide with satellite measurements, which raised a number of skeptical eyebrows.
my main argument is temperature measurements are untrustworthy up or down...
