Scientists finally admit that their computer models exaggerate the amount of global warming

Global warming scientists finally admit that their computer models exaggerate the amount of global warming

I’ve always suspected that the computer models that scientists use to predict global warming were programmed to exaggerate the amount of global warming.

And now, the scientists who write these computer programs have finally admitted that that is indeed the case.

The Telegraph reports:

Top climate scientists admit global warming forecasts were wrong

Top climate scientists have admitted that their global warming forecasts are wrong and world is not heating at the rate they claimed it was in a key report.

One of the central issues is believed to be why the IPCC failed to account for the “pause” in global warming, which they admit that they did not predict in their computer models. Since 1997, world average temperatures have not shown any statistically significant increase.

The summary also shows that scientist have now discovered that between 950 and 1250 AD, before the Industrial Revolution, parts of the world were as warm for decades at a time as they are now.

Despite a 2012 draft stating that the world is at it’s warmest for 1,300 years, the latest document states: “’Surface temperature reconstructions show multi-decadal intervals during the Medieval Climate Anomaly (950-1250) that were in some regions as warm as in the late 20th Century.”

The 2007 report included predictions of a decline in Antarctic sea ice, but the latest document does not explain why this year it is at a record high.

The 2013 report states: “’Most models simulate a small decreasing trend in Antarctic sea ice extent, in contrast to the small increasing trend in observations…”

The Daily Mail reports:

World’s top climate scientists confess: Global warming is just QUARTER what we thought – and computers got the effects of greenhouse gases wrong

Leaked report reveals the world has warmed at quarter the rate claimed by IPCC in 2007

Scientists accept their computers may have exaggerated

A leaked copy of the world’s most authoritative climate study reveals scientific forecasts of imminent doom were drastically wrong.

The Mail on Sunday has obtained the final draft of a report to be published later this month by the UN Intergovernmental Panel on Climate Change (IPCC), the ultimate watchdog whose massive, six-yearly ‘assessments’ are accepted by environmentalists, politicians and experts as the gospel of climate science.

Yet the leaked report makes the extraordinary concession that over the past 15 years, recorded world temperatures have increased at only a quarter of the rate of IPCC claimed when it published its last assessment in 2007.

Back then, it said observed warming over the 15 years from 1990-2005 had taken place at a rate of 0.2C per decade, and it predicted this would continue for the following 20 years, on the basis of forecasts made by computer climate models.

But the new report says the observed warming over the more recent 15 years to 2012 was just 0.05C per decade – below almost all computer predictions.

They recognise the global warming ‘pause’ first reported by The Mail on Sunday last year is real – and concede that their computer models did not predict it. But they cannot explain why world average temperatures have not shown any statistically significant increase since 1997.

They admit large parts of the world were as warm as they are now for decades at a time between 950 and 1250 AD – centuries before the Industrial Revolution, and when the population and CO2 levels were both much lower.

The IPCC admits that while computer models forecast a decline in Antarctic sea ice, it has actually grown to a new record high. Again, the IPCC cannot say why.

A forecast in the 2007 report that hurricanes would become more intense has simply been dropped, without mention.

This year has been one of the quietest hurricane seasons in history and the US is currently enjoying its longest-ever period – almost eight years – without a single hurricane of Category 3 or above making landfall.

I have said for years that if US politicians really believed in the AGW stuff they would have admitted that it is too late to do anything about it. Rather than carbon capture schemes to generate tax money for their pet constituencies they’d have been advocating that the US build a Sea Wall from Port Isabelle Texas to the Saint Lawrence Seaway and another one down the West coast. If they really think NYC is going to be inundated due to 450 of industrial pollution that is the only response that makes sense. It is too late to reverse the problem at this point.

Because they are not hiring every available Mexican to build that wall anything else they do is simply a scam

Nope.

Now that they have told you they are liars, they want you to trust them.

The sad thing about this entire fake science is that every scientist that supported “global warming” knows it is a lie.

I watched a program tonight called World History in Two Hours.

One of the items that had a major influence in the development of mankind was the ice age. Following the ice age, the earth got warmer.

I have no doubt that the earth’s climate changes, the thing I object to is the idea that man can have any effect on the climate (other than locally) or that man can do anything to keep the planet from warming or cooling.

What ever changes will take place in the future will be so slow that mankind will be able to do the one thing that makes us human, adapt.

Not only that...if it were real we'd see islands like the Maldives and Seychelles in the headlines constantly as the danger toward them grew more fierce.

It's all a huge SCAM designed by the communists to subvert the oil industry and rob the industrialized world of its wealth.

muslims, communists, liberals, democrats — all lie, all the time; all agenda, all the time...
If it were not for that, the world would have some hope...
There are just too many low-information, easily-manipulated groups for them to organize into majorities.

Exaggeration was the good news.

Egregious errors were more serious. The METS computer model predicted rainfall in the Central Sahara as the same as Ireland.

Hint to Libtards: Ireland is green, the Sahara just sand where rain has not fallen for 100 years.

Oops!

What utter Bull Shit!

This is not new news.

Whenever a computer model predicts exactly what you expect it to predict, chances are it is wrong.

and computers got the effects of greenhouse gases wrong

It's those damn computers, every time.

Time for the left to change the subject. "AGW? An-thro-po -- what? Never heard of it, but it sounds racist!"

Some great food for thought for everyone who ever told you that you were too dumb to live because you did not buy into all the global warming hysterics hook, line and sinker.

Face saving attempt?
Sorry, but these guys have totally lost all credibility by selling out the scientific method for politics.
They can rot in Hades.

Hell; every body knew about the Medieval Warm Period when I was in high school, and that was almost 50 years ago. We read about in in our World History books, including some thing that was called the Little Ice age that started about 1300 and lasted to about 1850 or 60, before things started to warm up again.
Perhaps if these oh so brilliant climate scientists would bother to read a little world history they could pull their collective heads out of their asses.
These brilliant minds should have learned this crap in high school. The climate fluctuates from warm to cool, it has for about the last 20 million years.

Elite liberal blowhards will have to push new scams on the world - global warming's played out.
