(CNSNews.com) - A federal advisory committee appointed by the Obama administration to produce a report on climate change says that if Earths climate were still primarily controlled by natural factorsrather than by man-made global warmingthen 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 Earths 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 Earths 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 peoples 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 morons couldn’t embarrass thrmselves to any greater degree even if they started showing up for work in pink pinafores and purple scrunchies.
To the democrats/socialists in the media and government it is always the fault of industry/capitalism/freedom. That idiots don't see what they are doing is beyond me.
the government provided trillion$ in grants to fund a hoax called global warming. This alone proves government/socialism doesn't work.
so they tried global cooling for a generation blame that on capitalism
then the next generation scare the population with global warming hoax. blame that on capitalism( big oil, coal, suvs). put guilt on Americans , terrorize them , tell them they and their capitalism is destroying the planet with global warming, that the ice caps are melting . and the sheep believe the lies. so they cry “we ought to do something” . then the media and government do something to take away our rights and freedoms, they ban bulbs etc. so now the earth is cooling so they change the name of global warming to “climate change” so now any change is blamed on capitalism .
Tell that to the folks in the northest who have been digging out from the most recent blizzard!
Prove it.
What a waste of taxpayer $$$$. These people make me sick. I hope EPA is a sequestration target. Dismiss these stupid committees and advisory counsels. Honestly.
“Can you tell us the source of your charts. I only see one identifier, the one for GISP 2, Greenland.”
I think I found most of those at www.iceagenow.info or www.wattsupwiththat.com.
“Unfortunately, those are somewhat hard to predict, except to say that at some point they will happen and kill millions if not billions of people.”
But ice ages do happen about every 100,000 years.
lol
It must have gotten stuck in the same Senate committee that has yet to pass a budget to the Senate as a whole.
Where I live, the ice used to be at least 1,000 feet or more thick. I would rather have to be concerned about alligators in the swamp behind my house that have this kind of ice return.
“The Younger Dryas which actually occurred when we seemed to be in the warming phase after the last ice age was likely caused by a major boloid event in the Northern Hemisphere.”
Furthering the same theory: the shock and heating of the ice sheet caused a huge chunk of ice over 1K thick and about the size of Greenland to slide off the ice sheet into the North Atlantic, blocking the Gulf Stream.
The morons actually now believe that a cooler planet will be better than a warmer one and are making plans to achieve that end.
I hang on this advisory panel’s every word. 8-P
Observe the incremental downward trend of temperature in successive cooling periods; also, note that the duration of each warm period above the 57 degree F “normal” axis is shorter. I note the article mentioned 1500 years and suggest everyone to Google “next bond event”.
Those empty cities in China may have been outfitted with district heating sourced from peripheral power plants yet to be sited (nuclear). The Chinese may be the ultimate preppers as they have tripled or more grain imports but are not suffering any domestic production issues. U.N. analyst are puzzled. Only connected need apply.
I remember years ago in the 1960s when the Chinese were still paranoid about getting into a nuclear war with the Soviet Union, that they would frequently have nuclear bomb drills where everyone would go to their designated shelters.
It could also have been caused by a huge surge of cold melt water and ice chunks flooding the North Atlantic

In the book “Lucifer’s Hammer”, written in the 1970s, the astronauts are talking about how we may be starting another ice age. One astronaut says that the heat and burning of fossil fuels may be forestalling it - but we’re running out of oil.
Peak oil and global warming as human’s fault is 30+ years old now. But we’ve found new ways to get to the natural gas, and we still have climate models that need a fudge factor to show warming in 50 years without showing an ice age 150 years ago.
. . . and I command that the next Ice Age is postponed indefinitely!
