Chinese Scientists Warn Of Global Cooling In New Study
New study has found winters in northern China have been warming since 4,000BC – regardless of human activity.
But the mainland scientists behind the research warn there is no room for complacency or inaction on climate change, with the prospect of a sudden global cooling also posing a danger.
The study found that winds from Arctic Siberia have been growing weaker, the conifer tree line has been retreating north, and there has been a steady rise in biodiversity in a general warming trend that continues today.
It appears to have little to do with the increase in greenhouse gases which began with the industrial revolution, according to the researchers.
Lead scientist Dr. Wu Jing, from the Key Laboratory of Cenozoic Geology and Environment at the Institute of Geology and Geophysics, part of the Chinese Academy of Sciences, said the study had found no evidence of human influence on northern China’s warming winters.
“Driving forces include the sun, the atmosphere, and its interaction with the ocean,” Wu said. “We have detected no evidence of human influence. But that doesn’t mean we can just relax and do nothing.”
Wu and her colleagues are concerned that, as societies grow more used to the concept of global warming, people will develop misplaced confidence in our ability to control climate change.
Nature, they warned, may trick us and might catch us totally unprepared – causing chaos, panic, famine and even wars as the global climate system is disrupted.
There are already alarming signs, according to their paper, which has been accepted for publication by the online Journal of Geophysical Research: Atmospheres.
Wu and her colleagues spent more than a dozen years studying sediments under Moon Lake, a small volcanic lake hidden in the deep forests of the Greater Khingan Mountain Range in China’s Inner Mongolia autonomous region.
They found that winter warming over the past 6,000 years had not been a smooth ride, with ups and downs occurring about every 500 years.
Their findings confirmed an earlier study by a separate team of Chinese scientists, published by the online journal Scientific Reports in 2014, which first detected the 500-year cyclical pattern of China’s summer monsoons and linked it to solar activity.
The 2014 research, which drew on 5,000 years’ worth of data, suggested the current warm phase of the cycle could terminate over the next several decades, ushering in a 250-year cool phase, potentially leading to a partial slowdown in man-made global warming.
Wu said the latest study, with 10,000 years’ worth of new data, not only helped to draw a more complete picture of the 500-year cycle but also revealed a previously unknown mechanism behind the phenomenon, which suggested the impact of the sun on the Earth’s climate may be greater than previously thought.
According to Wu, the variation in solar activity alone was usually not strong enough to induce the rapid changes in vegetation the research team recorded in the sediment cores of Moon Lake.
Instead, the scientists found the warming impact was amplified by a massive, random interaction between surface seawater and the atmosphere in the Pacific Ocean known as the El Nino-Southern Oscillation.
As a result of the research findings, Wu said she was now more worried about cooling than warming.
“A sharp drop in temperature will benefit nobody. The biggest problem is, we know it will come, but we don’t know exactly when.”

As with mostly all climate studies they have to couch their findings:
…..”our ability to control climate”……seriously.
…..”no evidence of human of human influence….”that doesn’t mean we need to relax and do nothing”
…..but we are willing to continue to study a non-issue and piss away taxpayers money. In this case its not USA money

“Nature, they warned, may trick us and might catch us totally unprepared – causing chaos, panic, famine and even wars as the global climate system is disrupted. “
As with most catastrophic events that impact humans life, hindsight is often 20:20.
The majority of the western world have bugger all as a contingency against a cold event happening. IMO this is a mistake, for it is just as likely (if not more so) to cool in the future as it is to bring any more BENEFICIAL warming.
Consider for instance, how in our electric powered world we are to survive with say the weather dropping to Dalton era temperatures in 50 years or less* — windmills and solar panels will just be so much useless junk.
Would the water, communication, or medical systems be able to cope? Our current limited local warehousing ensures trade and industry relies on a ‘just-in-time-ordering’ system. A system that requires both reliable transportation and reliable communication networks, networks that may well not survive sever cold. With trillions of dollars and billion of lives at stake, shouldn’t every government be prepared for what will probably happen in the next 50 years (maybe sooner*)? Or is it all about a quick profit for yourself (and love-ones) today and hope to survive tomorrow in some well stocked tropical land?
Today’s MSM is little more than old-time circus barkers shouting loudly about every warm day and staying quiet about cold weather trends*. The MSM, along with the current manipulations to temperature records by so many government agencies, appear as distractions away from the truth of the current slight cooling trend*. These distractions ensure the perception of probable futures are distorted, allowing the view that cooling is so very unlikely and therefore proper assessment of contingencies do not happen, are not planned, leaving everyone ill prepared should they happen. I’m not saying that it will happen but as it is a real and likely probability*, I’m asking are there any contingency plans for such an cold event and have they been tested?
Insurance always looks good after an unexpected event.

The 4000 BC date is critical. Onset of the largest global climate change since the end of the Pleistocene. An event of far greater magnitude than the Dryas oscillations, or the Minoan, Roman and Medieval Warm Periods, or the Little Ice Age and similar between those warming events. Severe repercussions for emerging human societies as well.
