(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.
The ice age was not exactly a climatic event. It was caused by the hot oceans after the Genesis judgment/flood coupled with constant volcanic eruptions filling the sky with dust, which blocked much of the sun’s heat.
Not likely to ever happen again.
The report went on to say the only thing that can cure the MILANKAVAN EFFECT is THE TAXAMAN THEORY. This theory calls for white people to reach deep down into their pockets to pay the government who in turn of course will use the money to pay reparations to the poor people of the world, which will then stop all Climate Change forever.

So, the arrogance of Obama has now surpassed that of King Canute.” <<

And Idi Amin.
That guy is crazy
Next they can fucus their efforts on preventing the house fly from becoming extinct.
Damn, I did not know that humans are now “God” like! We sure have a lot of power over Mother earth. /s
Amazingly, all the modern day aquatic live survived being made into acid soup....
Sometimes you read something so totally bereft of logic that you can’t even comment on it.
So.....
You are so right.
You better save up for a copper bullet - a big one.
Gallileo must be turning over in his grave......sunspots....the sun is on strike....if the sun doesn’t produce a good crop of sunspots by the middle of the next 11 year cycle....prepare for at best another 400 year long mini ice age.
There’ve been 20 such cycles in the last couple of million years AND we are about 5,000 years overdue for the next one to start.
LOL
Don’t ever bother opening your eyes.
In other news, the National Climate Assessment and Development Advisory Committee also issued a report calling for an end to the use of water for irrigating crops. “Water is for toilets” the commission stated, suggesting that farmers switch to Brawndo. “It’s got what plants crave” the report concluded.
Grubs, gotta be grubs.......
Without natural forces (for example, the sun) the Earth's temperature would be somewhere close to absolute zero so the climate is primarily controlled by natural factors with an arguably small incremental effect caused by human actions.
But now, because of humans, the committee says, the next ice age has been "delayed indefinitely."
How can you say it has been delayed indefinitely when the arrival time is indefinite. It's like saying a bus on a Mexican route is delayed indefinitely when the arrival time is listed as manyaña to begin with.
Also, we are currently in an ice age since there is ice on the polar caps. However we are in an interglacial period because the ice is restricted to the poles. If we weren't in an ice age Greenland and Antartica would be largely ice free except for their mountain ice caps.
