(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.
I call BULLZHIT.
Tell me why the grass in my southern PA valley is being replaced by moss and lichen! My own microclimate has gone from temperate to taiga over the past two decades.
We can predict now that we have reversed an Ice Age that would have occurred within the next 1,500 years? Vanity, thy name is Global Warming scientist/advocate.
But, But...There must be some mistake, Obama’s flunkies have spoken. ;-)
Oh great, if the administration says that the ice age will be postponed indefinitely, then that means that it is guaranteed to start next year.
So, the arrogance of Obama has now surpassed that of King Canute.
This will scare the low info voters to death, they’ll be demanding the government give them air conditioners with their free cell phones.
I didn’t realize it was on a strict schedule. They know that nobody alive today will ever be able to live long enough to see if they are right or not. lol.
And this bullcrap is why you are about to be denied the 50 year supply of oil from the Keystone Pipeline.
Wasn’t Obama supposed to “heal the planet” and lower sea levels in his first term?
And I’d bet money you’re right, if I was a betting man.
Is releasing this article on the day Snowpocalypse hits the east coast considered a manifestation of the Gore Effect?
Averted an Ice Age! We’re saved! Good News! Or is it?
These scientists and political hacks seem not to know the difference between a hockey stick and a big piece of ice.
Your tax dollars hard at work.
Now I have to cancel my mammoth hunt.
Well might as well look on the bright side.
Now I can plan a dinosaur hunt.
This is impossible because greenhouse gas emissions were skyrocketing at the time.
Why did I read that? I have a headache now because it’s so freaking stoopid!
