The latest IPCC report relies on a record of global temperature which reflects adjustments made by organisations like the Australian Bureau of Meteorology, in a process known as homogenisation of raw temperature data. This article by Dr Marohasy concludes: “The IPCC is wrong to label the recent temperature changes ‘unprecedented’. They are not unusual in magnitude, direction or rate of change, which should diminish fears that the effects will somehow be catastrophic.” See https://climatechangethefacts.org.au/2021/08/12/fussing-over-one-degree-of-simulation/ Dr Marohasy also wrote “‘Rewriting Australia’s Temperature History”’ in Climate Change: The Facts 2020, which explains what the Bureau of Meteorology does to raw temperature data. https://climatechangethefacts.org.au/2021/08/09/rewriting-australias-temperature-history/

I know I am labouring the point, but I suspect most people will not follow the link posted above, so here is the first paragraph of the summary: An energy system powered by clean energy technologies differs profoundly from one fuelled by traditional hydrocarbon resources. Solar photovoltaic (PV) plants, wind farms and electric vehicles (EVs) generally require more minerals to build than their fossil fuel-based counterparts. A typical electric car requires six times the mineral inputs of a conventional car and an onshore wind plant requires nine times more mineral resources than a gas-fired plant. Since 2010 the average amount of minerals needed for a new unit of power generation capacity has increased by 50% as the share of renewables in new investment has risen.

IEA (2021), The Role of Critical Minerals in Clean Energy Transitions, IEA, Paris https://www.iea.org/reports/the-role-of-critical-minerals-in-clean-energy-transitions This is a long article and is suggested reading for those interested in the supply of minerals to support clean energy.

Conversion of our power sources to solar wind and battery will require a massive increase in mining to produce the raw materials. The mining companies are salivating at the prospect. There is no such thing as a free lunch.

Trombones led the big parade

Do you not think people have sat where you are in the last two hundred years and said the climate is changing? It is a well-worn theme. It is recorded in newspaper articles that are easy to access. We just don't think across a time longer than our own experience.

CASA Avmed does not accept the advice of my cardiologist, he has to provide the raw test results to them. (Wrong forum I know, but I couldn't help it). BTW they renewed my medical - yippee.

Octave, I am a geoscientist and mining engineer so I receive a lot of material from my peer group. I have said before, I believe that geoscientists are the best people to opine on climate. That is their profession. Geo = Earth. They study the planet earth. I don't argue the same for mining engineers, though they are good at planning from limited data. I don't claim to be any sort of expert, but I rely on the geoscientists who do study climate. I was looking forward to your views on Humlum's report, as it seems to me to be a fact-based summary of the subject matter. I don't undertand why you (and many others) go straight to attacking the credibility of the author of these reports instead of saying how or why they are wrong.

Abstract: It has been discovered that there appears to exist a close relationship between relative differences in total solar irradiance and the atmospheric temperature, at a pressure of 1 bar, on all three terrestrial-type bodies which possess thick atmospheres. The apparent relationship is through the quaternary root of total solar irradiance at 1 bar, and applies to the planetary bodies Venus, Earth and Titan. The relationship is so close that the average surface atmospheric temperature of Earth can be easily calculated to within 1 Kelvin (0.5%) of the correct figure by the knowledge of only two numbers, neither of which are related to the Earth’s atmosphere. These are; the atmospheric temperature in the Venusian atmosphere at 1 bar, and the top-of-atmosphere solar insolation of the two planets. A similar relationship in atmospheric temperatures is found to exist, through insolation differences alone, between the atmospheric temperatures at 1 bar of the planetary bodies Titan and Earth, and Venus and Titan. This relationship exists despite the widely varying atmospheric greenhouse gas content, and the widely varying albedos of the three planetary bodies. This result is consistent with previous research with regards to atmospheric temperatures and their relationship to the molar mass version of the ideal gas law, in that this work also points to a climate sensitivity to CO2 - or to any other ‘greenhouse’ gas - which is close to or at zero. It is more confirmation that the main determinants of atmospheric temperatures in the regions of terrestrial planetary atmospheres which are >0.1 bar, is overwhelmingly the result of two factors; solar insolation and atmospheric pressure. There appears to be no measurable, or what may be better termed ‘anomalous’ warming input from a class of gases which have up until the present, been incorrectly labelled as ‘greenhouse’ gases.

My great grandfather took off in 1904 leaving about ten children and a wife. They never heard from him again. I tracked him down via records and found he worked as a wharf labourer in New Zealand for another forty years. He had never tried to hide his identity, but in those days they couldn't find him.

After the Germans were defeated the French executed many collaborators and shaved the heads of women who had consorted. We should not be surprised if something similar happens.

Not all workshop activities are equal. Drilling a hole is boring, while fastening metal together can be rivetting.

Four things greater than all things are, -- Women and Horses and Power and War. We spake of them all, but the last the most, For I sought a word of a Russian post, Of a shifty promise, an unsheathed sword And a grey-coat guard on the Helmund ford. - From The Ballad of the King’s Jest, by Rudyard Kipling. 1890.

Answer in Chinese if possible.

Something will auto-correct the humans sooner or later, I reckon this has an even chance.

The more Covid becomes endemic, the more opportunities it has to mutate into something truly nasty. If it has the greatest impact in countries with high birth rates, and this is plausible, then the overall rate of growth of global population will fall dramatically or even reverse into a decline. Once the decline begins it will continue due to low birth rates in wealthier countries including China and Japan. Taking the long view of history, some may view this as a good thing.

Facebook keeps suggesting my ex as a friend, more than 30 years later.

The operation to turn a woman into a man is known as an addadictome.

Topic: We are witnessing the end of the world as we knew it. Mother Earth has found a way to solve the human population problem. The virus will evolve faster and in more ways than we can combat. The global population will fall substantially and many things we have taken for granted will no longer be possible. Like people at the beginning of a long war, we have difficulty imagining how our lives will change. Discuss.

My first desktop computer at work was a HP9825, in 1977. It had an audio cassette for storing programs and an A4 colour pen plotter. It ran "HP modified BASIC". I enjoyed programming it and the attention it got from being the first desktop computer in our office. It has its own website today, which begins: Now vanished into the mists of time and computer evolution, the Hewlett-Packard 9825 desktop computer was way before its time. In many ways, the development of the HP 9825 and its brethren marked a significant turning point for the computer industry. It foreshadowed the PC revolution fully five years (that’s 50 years in computer time) before the IBM PC burst into existence in 1981.

Climate Change Denier is a pejorative term derived from the term Holocaust Denier. The Holocaust happened, human-induced climate catastrophe is a hypothesis.

I will definitely put no religion. If the government realises most of us don't believe in a big fella in the sky, a lot more rationality will apply to their decisions about things like taxation and education.

Avon powered the Comet and the Canberra, don't knock it!

In my family the previous generations had kept in touch with their UK "cousins" despite us having arrived in the 1840-1860 period. So up to the 1950s when someone from my parents generation went to England/Ireland/Scotland they looked up "cousins". That is almost extinct now, although my wife has a crazy English "cousin" who rings her once a fortnight. My wife's family left the UK in about 1903.
