(CNSNews.com) - A federal advisory committee appointed by the Obama administration to produce a report on climate change says that if Earth’s climate were still “primarily controlled by natural factors”—rather than by man-made global warming—then the next ice age would occur within the next 1,500 years.
But now, because of humans, the committee says, the next ice age has been "delayed indefinitely."
“Confirmation of what are called Milankovich cycles (cyclical changes in the Earth’s orbit that explain the onset and ending of ice ages) led a few scientists in the 1970s to suggest that the current warm interglacial period might be ending soon, plunging the Earth into a new ice age over the next few centuries,” the advisory committee said in a draft report released last month.
“Scientists continue to study this issue today; the latest information suggests that, if the Earth’s climate were being controlled primarily by natural factors, the next glaciation would begin sometime in the next 1,500 years,” says the report. “However, humans have so altered the composition of the atmosphere that the next glaciation has now been delayed indefinitely.”
The U.S. Commerce Department created the National Climate Assessment and Development Advisory Committee in December 2010. In May 2011, National Oceanic and Atmospheric Administration Administrator Jane Lubchenco named its governing panel. The committee was charged with developing a new National Climate Assessment report, following up on two previous reports published in 2000 and 2009.
In January, the advisory committee released an 1,146-page draft report so the public could review it and comment on it.
The statement that the next Ice Age had been indefinitely postponed came in a set of questions and answers appended to the end of the draft report. The question posed was: “What about global cooling predictions in the 1970s?”
The answer provided by the draft report blames the hyping of an impending “ice age” on the “popular press.”
“An enduring myth about climate science is that in the 1970s the climate science community was predicting ‘global cooling’ and an ‘imminent; ice age,” it says.
“Where did all the discussion about global cooling come from?” it asks.
“First, temperature records from about 1940 to 1970 show a slight global cooling trend, intensified by temporary increases in snow and ice cover across the Northern Hemisphere," it says. "Unusually severe winters in Asia and parts of North America in 1972 and 1973 raised people’s concerns about cold weather. The popular press, including Time, Newsweek, and The New York Times, carried a number of articles about the cooling climate at that time.”
The report says average U.S. temperatures have increased 1.5 degrees Fahrenheit since 1895, but will increase anywhere from 3 degrees Fahrenheit to 10 degrees Faherenheit by the end of this century depending on future human activity.
“The amount of warming by the end of the century is projected to correspond closely to the cumulative global emissions of greenhouse gases up to that time: roughly 3°F to 5°F under a lower emissions scenario involving substantial reductions in emissions after 2050 (referred to as the 'B1 scenario'), and 5°F to 10°F for a higher emissions scenario assuming continued increases in emissions (referred to as the 'A2 scenario'),” says the draft.
The report claims the planet will be a cooler place if the nations of the world create a “scenario” where there are fewer people born and fewer emissions of fossil fuels.
“At the lower end of the range,” it says, “the B1 scenario represents a world with lower population growth, higher economic development, a shift to low-emitting efficient energy technologies that are diffused rapidly around the world through free trade, and other conditions that reduce the rate and magnitude of changes in climate averages and extremes as well as increased capacity for adaptation.”
These bozos can’t forecast what the cost of ObamaCare really is. How the heck are they credible forecasting ice ages, for Pete’s sake!!
To even question the above “findings” would be anti-scientific, according to today’s scientists, without any hint of irony in their proclamations.
Just good old plain hubris to think that mankind can stop the Earth from doing its thing.
How convenient.
Wishful thinking (and an argument in favor of making efforts to actually cause some anthropogenic global warming): a new ice age would be far more catastrophic to civilization than a 4 degree celsius rise in mean global temperature.
Inasmuch as the climactic record is consistent with a sudden shift from warm conditions to ice age conditions over the timescale of a decade, I wouldn’t be entirely shocked were most of us posting here to live to see the start of the next ice age.
Speaking of ice ages, there have been numerous ice ages in earth’s history.
During one ice age, Chicago was buried under a mile of ice.
Yet, somehow, the earth warmed before we had SUVs and coal fired power plants. The enviro-extremists never can explain these natural warming cycles which had nothing to do with man made global warming.
It wasn’t just the “popular press” pushing the idea of an impending ice age. I walked in on the end of a science class at my college where the prof was pushing the idea in 1970. They were blaming industrialization then, as well.

Should be starting anytime now!

obozo did it by XO.
Yes I remember very well in the late ‘70’s. Climate scientist at that time thought increased industrial SO2 and TSP would lead to solar defection and a new ice age. They were wrong then, and they are wrong now. Vulcanism and Sun Cycles control it all. Not man.
There must be clowns ... don’t worry they’re here.
Is this by decree? Do the pinheads have a pipeline to the All Mighty? Or is there some other form of irrefutable evidence?
Just think of what would happen if you put your face into a car exhaust system and took many deep breaths. Now multiply that by all the cars on the planet. It makes one dizzy just thinking about it.
Where do I send my contribution?
If this were the Middle Ages these clowns would be counting angels on the heads of pins.
New boss—same as the old boss.
The sadest part of the story is that California has totally bought into the climate change myth and has thoroughly institutionalized Agenda 21 efforts to reduce greenhouse gases in general planning, regional planning and regulation in housing and development, transportation, water management, timber management, agriculture, fish and wildlife management, healthcare and business. Like lemmings we are jumping off the fiscal and economic cliff following duped progressive bureaucrats and legislators.
