Remarkable new scientific evidence has been published that suggests abrupt rises in temperature have been a feature of global climate change going back to the iceless Jurassic period over 150 million years ago. These warming events, in which the temperature rose many degrees centigrade within decades or less, were thought to be a feature of the last ice age up to 100,000 years ago and confined to Greenland and the North Atlantic. This dramatic new evidence suggests they were a feature across the globe going back millions of years.
The findings will give fresh insight into the highly politicised debate around climate science and Net Zero. It is constantly argued that the recent small rise in global temperature, which started over 200 years ago, is unprecedented, and is caused by humans burning fossil fuel. Far from being unprecedented, it seems similar changes in temperature over comparable, and often shorter, time periods were ubiquitous across paleoclimatic history stretching back to the Jurassic era.
A group of French scientists led by Slah Boulila from the Sorbonne carried out extensive research into what are known as Dansgaard-Oeschger (DO) events. These events, named after two paleoclimatologists, track 1,500 year temperature cycles when large rises suddenly occurred followed by a reversion to ice age conditions. The scientists noted warming up to 15°C within a few decades, “pointing to abrupt and severe changes in Earth’s past climate”. Scientists and green activists seeking to downplay the significance of large changes in the paleoclimatic record have suggested that oscillations of northern hemisphere ice sheets and surrounding waters played a part.
But the French scientists now say that paleoclimatic studies have shown that the 1,500-year climate cycle is no longer restricted to the North Atlantic Ocean of the last glacial period. “The 1,500-year cycle is documented in both hemispheres, in other oceans and in continents, such as in lake and river deposits, in pollen fossils, in stalagmite proxy records, and in loess-paleosol deposits,” they add. In conclusion, the scientists note that the analysed paleoclimate records of the late Jurassic “supports the global nature of DO-like event, and in particular that their potential primary cause is independent of ice sheet dynamics”.
Of course, the inconvenient fact that the planet has seen countless significant temperature rises in the past is not unknown. Back in 1999, before global climate hysteria got into its full stride, geographer Mark Maslin from Imperial College co-wrote a paper on “sudden climate transitions” in which he stated: “All the evidence indicates that most long-term climate change occurs in sudden jumps rather than incremental change.” He went on to add that some, and possibly most, large climate changes involving movements of several degrees occurred at most on a timescale of a few centuries, sometimes decades, “and perhaps even a few years”.
These days Maslin is Professor of Earth Systems Science at the politically-named UCL Anthropocene, and tweeting that “Earth is already becoming unliveable”. A frequent guest on BBC programmes, Maslin has explained that the Anthropocene began with European colonisation and mass slavery. The origins of racism and climate emergency “share common causes”. Climate change politics helps build “a new political (and socio economic) system”. In 2018, he was one of a number of eco-activists who signed a letter to the Guardian saying they would no longer “lend their credibility” by debating climate change scepticism.
It would seem that the record of large – often startlingly large – rises in past temperature needs to be downplayed if the command-and-control Net Zero project is to be promoted. Removing fossil fuel from modern lifestyles within less than 30 years demands enormous economic and societal sacrifices, particularly from poorer members of society and across the developing world. It can only be done if enough people and populations believe there is an existential threat to the planet from recent warming and model-projected future warming.
Meanwhile, science continues to produce evidence of major temperature changes in the past. Two recent studies suggesting much higher temperatures are noted by the No Tricks Zone climate science site. A new study is said to have shown that it was warm enough 8,000 to 5,000 years ago for the plant Ceratopteris to have grown at 40°N in northern China. These days, the plant’s limit is 34°N, suggesting that winter temperatures in the past needed to be 7.7°C higher than today. Another warmth threshold species study argues that the Arctic Svalbard needed to have been 6°C warmer than today during the early Holocene. This is because 9,000 years ago, molluscs survived 1,000km north of where they are currently found.

Are you sure.? This is not what those nice people at the BBC have been telling me…
Also, as carbon dioxide levels follow temperature by 500-1000 years, then if there’s a 1500 year temperature cycle then there’s a similar carbon dioxide level cycle with a phase difference of approximately +750 years, if the temperature is a sine wave then CO2 levels follow a cosine wave.
Those pushing net zero don’t want to know, climate change is a profitable venture. Already rich but wanting more, they’ve spent their lives in incomparable luxury and excessiveness, most people would have to live many lifetimes to reach a year of their self indulgence. Now they tell us, its for ‘our grandchildren’, (Rishi) and others, I’m sure his children won’t suffer, now, due to net zero, but billions will.
Randall Carson discusses this very thing (along with some other fascinating subject on human history) on Joe Rogan.
Its long and seven years old, but worth a watch:

You only have to look at the way modern weather maps use orange, red and dark red smudged colour that resembles fire to realise we’re being played. I did semiotics as part of Film Studies A-Level 30 years ago and we were taught about how manipulation of image affects emotional reaction (it was, ironically enough, steeped in Marxist Critical Theory so I got to learn all their tricks).
It reeks of the Nudge Unit, whose existence isn’t even well known outside of the non-legacy media. The reason the legacy media isn’t going after the very dangerous nudge units and the violation of democracy their existence represents must be that they’ve been threatened or bought off in some way. State psy-ops units using brainwashing techniques on citizens ought to be front page news.
If their existence appeared anywhere at present, it would most likely be on GB News. Only a couple of years old, but it’s doing a good job at the moment.
Anthropocene began with European colonisation and mass slavery
This must have been some time before the Greco-Persian wars, then, as the Greek city states erected colonies around the Mediterranean and generally, had masses of slaves. Sparta is a noteworthy example here as the city was ruled by a relatively small class of Dorians who were originally invaders and had turned the original population into a slave class (the helots). Except that slavery was obviously already common practice all over the world before the era of classical Greece.
The classic Greeks were also pretty racist: They believed their people to be divided into the races Aeolian, Acheans, Dorians and Ionians, all with certain hereditary traits, and summarily referred to all other peoples as barbarians (they considered to be below them).
Can some $deity please save us from all these uneducated morons with fancy titles who believe the history of mankind started when America was discovered and colonized?
Maslin has explained that the Anthropocene began with European colonisation and mass slavery.
Just in case this isn’t clear to someone: This ludicrous statement of (North-)American exceptionalism, ie, that something which has never before happened anywhere in the world occurred when Europeans started settling in America[*] and that this inherent evil is the cause why the planet is doomed unless something is done to overcome evil Europe is the final nail in the coffin of climate change. We can as well call that critical weather theory
and file it among all the other woke nonsense (some) people in the USA invented because they’re forever pissed off that they had to learn stuff in school (in the 1960s) they never cared about when all they really wanted to do is to go on holiday to interestingly exotic places and generally screw around as much as possible.
[*] An example: The bubonic plague came to Europe from Asia and killed as much as 80% of the population in some regions. Similar events have happened with other diseases, most of them earlier.
It looks like the bubonic plague is the model on which the Davos Deviants have based their planning. At least in terms of outcomes anyway.
That was a reference to Maslin’s article. A lot of American Indians died of various infectious diseases the Europeans brought with them which had become endemic among them. According to him this Depopulated (!!1) northern America and the (evil) Europeans than just occupied the essentially empty continent. That’s absolutely laughable, considering that the history of early Euroean settlements is one of constant warfare with the native population, with the latter more often than not in the much better position. Eg, one of the people who became victims of the Salem witch trials was (among other things) accused of being in league with the devil because he had miraculously survived a number of Indian attacks where most of the other settlers he had been living with perished.
It’s also absolutely not unheard of, that’s why I mentioned the black death which presumably originated in China, travelled along with the traders until it had reached Europe and then seriously decimated the European population. Stuff like this happens on this planet and it has happened at all times and to all people.
Could you please send a copy of this to Prince Charles. He assured us the other day that 3 days of very hot weather because the wind was blowing from the Sahara is proof that he’s right about climate change.
As for Maslin no longer lending his credibility by debating climate change scepticism, the obvious answer is “what credibility?” He’s a propagandist ….. a scientist will ALWAYS debate because science is NEVER settled.
This is a fantastic graph for those that haven’t seen it. It compares the media’s massively zoomed in representation of our recent warming to the same graph zoomed out and plotted it on a scale of daily human temperature experience across the world. Send this to anyone zombie you might know who’s ever used the term ‘climate emergency’..
