Scrap Net Zero: Dramatic New Ice Core Evidence Shows Current Century Warming Common Throughout the Last 400,000 Years

Lies, disinformation and fictional accounting are the order of the day as a desperate hard-Left UK government, aided by its pet Climate Change Committee, tries to keep its impossible Net Zero controlling agenda intact. The bedrock unproven science claims surround the suggestion that recent limited global warming presents an existential threat to the planet. Statistics are routinely tortured to produce claims of up to 1.7°C warming from the pre-industrial age, notable as reported in a recent silly ‘Trump’s brave new world’ article by Ambrose Evans-Pritchard in the Telegraph. In fact, temperatures have only risen by around 1.1°C over the last 100 years. Moving away from the tortured stats measured over a few cherry-picked months, it has recently been discovered from ice core records that rises of 1.1°C in the current interglacial, which started about 20,000 years ago, occurred in about one in six centuries.

Moreover, similar, although less frequent, temperature rises appear in earlier periods going back 150,000 years. The frequency here was around one in six to one in 20 centuries. Of further interest was the discovery that these routine rises became rarer before this date. None of these findings suggest that current warming is either unusual or solely caused by humans burning hydrocarbons. Needless to say, the findings will be ignored – as is most other inconvenient palaeo evidence – by climate headbangers and political activists prepared to fib about the climate and waste trillions of pounds on their command-and-control Net Zero fantasy.

In the meantime, we can all laugh at one of Damian Carrington’s recent beauties published in the Guardian, headlined: “Point of no return: a hellish ‘hothouse Earth’ gets closer, scientists say”.

Not yet in the rapidly pauperising UK, but in many others parts of the world, Net Zero is dead or entering its death throes. In addition, the 30-year ‘emergency’ around ‘settled’ climate science, with its political orders not to question scientific opinions, is being seen for the scam it is. Even in the UK, long gone are the days when this piffle from BBC presenter Jeremy Vine could be tweeted, seemingly with a straight face. 

In so many ways, this ludicrous tweet sums up the dumbing down of education over decades. This allowed climate psychosis to take general hold, with a school-skipping doom goblin child meeting a famous TV voice over-artist to the accompaniment of chirping praise from another UK State broadcasting presenter.

Climate models, which are ultimately responsible for all the Attenborough/Thunberg et al ‘tipping point’ nonsense that drives the mainstream settled narrative, are almost invariably wrong in their conclusions. Decades of failed predictions confirm the fact that they cannot realistically model a chaotic climate. Knowledge of the role of clouds, the Sun and even ocean and air currents is too basic to be effectively modelled. Using these models should come with a warning that any human involvement in changes in the climate cannot be distinguished from natural variation. Computer-generated claims to be able to attribute individual weather events to human involvement should be supplied with a picture of the late Tommy ‘Just Like That’ Cooper, a great comedic conjuror famous for wearing a Fez and waving a magic wand.

It is natural variation that the headbangers try to ignore. Only then can they demonise recent gentle global warming and spin the lie that collectivist action can stop the weather. This is why this latest temperature paper is important, and why it will be ignored in the mainstream. It would be impossible to impose a Marxist wet dream costing trillions of pounds and involving horrendous lifestyle changes if it became generally known that the recent rise in temperature was common throughout the last 200,000 years.

Written by the Emeritus Professor of Computer Science at Kingston University Les Hatton, the paper analyses publicly-available temperature information going back around 420,000 years from the Epica-Vostok Antarctica ice core dataset. It accepts that the data do not provide a global figure, which it is noted is a statistical amalgam with many assumptions and numerous proxies. The more cynical might note here that current global temperature datasets contain a great deal of ‘junk’ unnatural heat measurements, and are subject to considerable suspicious retrospective adjustments. The author notes that the Vostok ice core is a ”pure” record since it is based on a single location in a consistent manner over a long period. Again, sceptics might welcome the lack of measurements next to airport runways, solar farms and glass-clad high-rise buildings.

Professor Hatton has some interesting general comments about temperature, noting that interglacial peaks starting 400,000 years ago appear to be getting hotter. The interglacials are followed by ice ages and these seem to be getting colder. Carbon dioxide levels do not seem to play a large part in all this natural variation as the graph below going back 200,000 years clearly shows. In some periods, the red temperature line moves in a different direction to the blue CO₂ marker.

Carbon dioxide levels in this dataset vary between 170 parts per million (ppm) and 280 ppm. If the level had fallen below 150 ppm, photosynthesis would have stopped and an almost certain mass extinction of land-based life would have occurred. Hatton observes that in 556 centuries of the 800,000-year Vostok database, CO₂ was below 190 ppm.

Whatever the cause of the recent upturn in CO₂, which has ‘greened’ the planet by up to 20% in the last 50 years, we seem to have dodged a very dangerous extinction bullet.
