A team of Chinese researchers says a period of global cooling could be on the way, but the consequences will be serious.

A 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.”

Moon Lake, a small volcanic lake hidden in the deep forest of China’s Greater Khingan Mountain Range, where a team of scientists spent more than a decade studying the secrets hidden in its sediments.

Wu and her colleagues are concerned that, as societies grow more used to the concept of global warming, people will develop a 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 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 of temperature will benefit nobody. The biggest problem is, we know it will come, but we don’t know exactly when.”

NASA tends to agree but on a shorter time frame. They are suggesting that the next 30 to 35 years will be considerably cooler than normal - to the point that it might begin an ice age of short duration.

It looks like the global warming may be out the door.
However, "green" homes will help with cold as well as warming cilimate.
So more sealed homes with air exchanger & insulation is still a good ideal.
But if we are going into an ice age, no winter crops, that means Green houses with ground storage pits to keep plant alive in -0 nights.
Ice age would be a "end of the world as me know it" event.
It would hit the southren state harder then noerthren state, but it would be bad for all.
Fewer animals, because keeping them in winter would be a real pain, unless you insulated their home as well as yours.
Or put them in a basment, then you would not have to leave the warmth of home, to feed them or butcher them. feed the scraps to the hounds.
Survival of the fitest will be real & only the flexable & the preparded will make it.

The mini-ice age that is "expected" will not be a "global" event but it will change the zones for growing crops. The current USA corn and wheat belt will have to grow different crops - probably root crops that are less sensitive to short growing seasons and more cold weather crops. We also have a magnetic pole reversal going on and it would be best if that happened while the sun was quiet so we don't get extra radiation without our magnetic field to protect us. Maybe it is all meant to happen at the same time for that reason.

Mini-ice age will be global.
Ice & snow will not cover the earth, but every cilimate will be cooler then it is now.
The equater will not freeze or there would not be any banana or pineapple, they would have died out in the cold long ago.
But many of the plants we take for grant, will die out, because they can not stand the cold.

It's all called the weather.
Tired of whackos making money on this.

You folks appear to be jumping the gun.

Well, back in the 70's it was the 14-mpg cars that saved us all from this one:

1977.

Please, burn some coal to save us all!

Well it's too bad I wasn't paying more attention but a few month back I heard a weather man mention that if we got another winter like last year, when it got extremely cold in the Great Lakes region and there were reports of some very low minus temps, that we may be going into a cooling period. Anyway, here I am getting flash backs to the 1950 blizzard in Washington, I remember it started when I was in class and it sounded like sand hitting the windows, the teachers told all the students to gather their coats and lunch boxes and get on the buses now and by the time I got let off the bus at my bus stop I couldn't see my hand if I extended it out as far as I could reach, thankfully my foster dad was waiting for me and took me home. In the next few days the storm had caused huge waves to throw water, from the bay we lived on, clear up on the bay window of our home and all over the lawn and scrubs so that there was a greenish colored ice covering everything up to an inch thick. My foster dad covered the big window with a sheet or blanket because he was afraid it might shatter. All that I can remember was that it was really cold and that the heating system was a floor furnace, which we had to stand over to get any warmth. When I tell people about the next thing, they don't believe what I tell them, the salt water bay we lived near froze over with green slushy ice and it also froze over the next few winters due to that blizzard. You couldn't walk on the ice because it was more like slush but it froze and from the research I have done many years later, the bay froze over due to streams that fed into the bay, fresh water floats at the top of salt water. The main thing I remember was the extreme cold that that storm brought, my hands hurt just thinking about those days. If you get a chance do a Bing search on the January 13, 1950 Blizzard in Washington, it was nasty, something I hope I never have to go through again.​

Yeah, it gets pretty hard to wave the 'Global-Warming' flag when stuff like this happens:

I've seen a lot of salt water freeze over. Once, when I was working on tugs we had to break through 13" of ice to get the oil barge back to fuel a logging camp. Once we were close enough we hauled the fuel hose over the ice. It was a floating camp and there was a fishing boat frozen in also. They were taking the fuel out of the boat to heat the homes.

My senior year in high school the waterfalls around town froze. That was gorgeous.
