Skip to comments.Global warming is just HALF what we said: World's top climate scientists admit...
Posted on 09/15/2013 11:38:14 AM PDT by matt04
A leaked copy of the worlds 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.
They are cited worldwide to justify swingeing fossil fuel taxes and subsidies for renewable energy.
Yet the leaked report makes the extraordinary concession that the world has been warming at only just over half the rate claimed by the IPCC in its last assessment, published in 2007.
Back then, it said that the planet was warming at a rate of 0.2C every decade a figure it claimed was in line with the forecasts made by computer climate models.
But the new report says the true figure since 1951 has been only 0.12C per decade a rate far below even the lowest computer prediction.
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.

There is no global warming period . the Earth is getting colder. look up solar cycle 24, and 25
funny the Sun does affect climate.C02 never could affect climate. these socialists created the global warming hoax to destroy capitalism , grow government and enslave us . and you think that there probably is some man made global warming ? you are brainwashed by the media
Global warming and cooling is bogus. Climate change? Well....the climate has been changing for 400 million years....there’s nothing new about this.
It’s all a gimmick. You buy into some story because you are that naive. You should ask questions...but people get fussy if you challenge their story. Kinda like the inner-Earth crowd of the 1880s, who ran into towns....selling bogus maps to folks for a dollar, and everyone was accepting of the inner-Earth.
I always thought the tree ring stuff was pure hogwash. I have cut a few trees in my life, having grown up on the farm and pulled my end of a five and a half foot long saw from the time I was about ten or so. I have a collection of four chain saws now. I have examined some tree rings while resting from all that exertion and I can understand that they give an indication of rainfall amounts in different years but I never understood how anyone could claim that they gave an accurate indication of temperature other than a connection between drought and high temperatures in summer. It hardly seems to be a basis for the precision they claim. They would be more credible if they just claimed psychic abilities rather than claiming to decipher all that from tree rings.
They’d be more credible if they claimed use of goat entrails.
The fact that CO2 and CH4 trap heat is not an invention of a "socialist" or "the media," it was first recognized by a 19th century British chemist named John Tyndall and has been supported by controlled studies since then, such as comparing oxygen 16/18 relative abundance (a good indicator of evaporation and therefore average temperature) in Antarctic ice cores to C02 levels. What was Tyndall's "socialist agenda" in making this discovery? It has nothing to do with politics and everything to do with physics and chemistry.
People who make statements such as "CO2 cannot cause climate change" sound as ignorant as the extremists on the other side who say that our CO2 emissions will lead to doomsday, and they make convenient targets for Gore and his hysterics because they make global warming critics seem even more ignorant and irrational.
Those who want a truly objective and scientifically informed treatment that deflates the claims of both the-end-is-nigh crowd and those who deny basic chemistry and physics, take a look at Climate of Extremes by Michaels and Balling. Both are climatologists, Michaels is now employed by the libertarian Cato institute. In other words, they have far more credibility on this subject than a lot of the loud-mouths on both sides of the debate.
If your data is off by 1% after 1 computation your result is off by 1.5%. Now with a 1.5% error in the data the next computation is off by 2%, etc, etc, etc. You need really really need exceptionally good data to effectively use a computer model. Plus lots of logic to ensure the data does not go wacko on you. Systems as complex as climate are simply beyond are current ability to model with the desired accuracy. Just look at computer models path/intensity predictions for Topical Cyclones. They are all over the place and generally useless 3 or more days out. And climate prediction is a more difficult problem.
I like to remind people that we are in an Ice Age so a little warming might not be a bad thing. Not that I think we are warming now, in fact I think the exact opposite.
you believe that C02 affects climate. you believe these socialist tyrants in the media, gov, politicians and scientists.
C02 level doesn't affect climate. that's the most ridiculous thing ever.
get a clue
you are a brainwashed low info voter
what are you doing on this site?
the Earth is getting colder .
you and all your fellow democrats are jokes
Since you consider yourself such an expert, in a couple of paragraphs, explain how one may use oxygen isotopes to estimate past temperatures, assuming you even know what an isotope is, and present a rational critique of this methodology. Oh. That's right, you can't. The best you'll come up with is"Isotopes are just media brainwashed liberal Democrats!"
Sometimes I wonder if the dimmer posters on sites like this one are just liberal plants put here to make conservatives look bad.
Don't tell me this, tell it to the numbskull on this thread who insists that CO2 has nothing to do with climate. Perhaps Mr. Media can explain why Venus has surface temperatures that can melt lead if CO2 and CH4 don't influence climate.
I like to remind people that we are in an Ice Age so a little warming might not be a bad thing.
I find the case Michaels and Balling make convincing - that there is a small century plus warming trend, and that it's just as likely to be somewhat beneficial to parts of the world as harmful to others, and that the best data suggest that the effects are marginal.
You are a joke and a liberal/democrat
CO2 does NOT affect the Earth's climate.
CO2 levels do NOT affect the Earth's climate.
CO2 does NOT affect the Earth's climate.
you say C02 does affect the Earth's climate. you buy into the socialist lies . so you want us enslaved to the government and to socialism. they create this lie that C0 affects climate so that they can control us and our businesses . and you are trying to propagandize , to further that lie.
Here’s a clue :CO2 does NOT affect the Earth’s climate. regardless of what you and your liberal mainstream media ,UN , and fake global warming science say.
CO2 does NOT affect the Earth’s climate.
CO2 levels do NOT affect the Earth’s climate.
CO2 does NOT affect the Earth’s climate.
you say C02 does affect the Earth’s climate. you buy into the socialist lies . so you want us enslaved to the government and to socialism. they create this lie that C0 affects climate so that they can control us and our businesses . and you are trying to propagandize , to further that lie.
You are a joke and a liberal/democrat
your name calling just further confirms you are a complete idiot and a socialist
you have the IQ of lint
The Earth is cooling and will get much colder in the coming decades because of Solar cycle 25. the Sun does affect climate C02 does not , get it yet moron? you are the dumbest idiot just like all the leftist idiots.
I’ve been in this fight against the AGW for many many years but I must tell you you lose all creditability when you say stuff like “CO2 does NOT affect the Earths climate” that is demonstrably false. Now if you mean atmosphere CO2 at current levels +- a few hundred ppm will not have a significant effect on climate you might be right.
At one point in Earth’s history the planet was covered with ice (Snowball Earth). Miles dept at the poles and meters dept at the equator. The only thing that saved the Earth from it’s frozen state was CO2. Volcanoes belched out CO2 for millions of years and since the Earth was frozen the CO2 stayed in the atmosphere. Eventually the CO2 concentration got so high (300,000 ppm) that the Earth warmed and the ice melted. From that event we know that large amounts of CO2 in Earth’s atmosphere can in fact cause warming. And then there is Venus, very hot lots of CO2.
DEEP not dept
Exactly. Ignorant and demonstrably false statements like that only serve to discredit reasonable critics of global warming hysteria.
You say that C02 affects the Earth’s climate. that’s ridiculous. C02 does NOT affect the Earth’s climate. that is the main argument the leftists and the media say. you agree with them . this is what they say to justify them controlling our “carbon”. so Obama’s EPA is shutting down coal power plants, they are making mileage requirements for future cars, banning 100 watt light bulbs and many other tyrannical things . you agree with them growing the government and creating a socialist state .
you are spreading leftist lies on a conservative site
But what is provable, documented and undeniable is that co2 does cause warming. There have been several events in our planets history where run away co2 warming has occurred. But the co2 levels were way higher than 400 ppm, more like 300,000 ppm in the case of snowball Earth.
I am a math and science kinda guy and I just go where the science takes me. AGW appears to me to be junk science, notice I said appears. Climate is to complex a system for humans to understand with certainty what will happen if X or Y changes by Z amount. So for the time being I am a man made global warming skeptic but I do not deny that co2 does cause warming. I just do not think man is putting enough co2 into the atmosphere to make much of a difference one way or the other.
the Sun which is a star , and which a million Earths could fit into does affect the Earths climate. without the Sun the Earth would be the temperature of interstellar space which is around -400 degrees . The earth is a cold little insignificant rock compared to the sun and the immensity of the universe. in your little brainwashed by the media minds you think that a gas that is 0.039% , that is 4 hundredths of 1%, of the atmosphere affects the Earth's climate . to do that this increase which is a percentage of that 0.039% would have to over come the Sun's influence which is a massive nuclear furnace , a star. you leftists can't fool someone that is an independent thinker. and yes i ‘ll tell you something that will hurt you more than anything :i am for freedom and I will never anything you say, nor believe your mainstream media , nor your stupid scientists , nor your gov agencies, so I am Republican. and I'm Republican for life . and i know that hurts you socialists more than anything that I remain Republican. nothing you can say can influence what I think
Whatever, you are not worth the time it takes to post to.
. you don’t have freedom not even a free mind you and the rest of the democrats are programmed robots, programmed by the liberal mainstream media
CO2 affects the Earth’s climate lol . that is the dumbest thing ever lol lol lol
and i don’t post to you just to beat down your ridiculous leftist lies. your just lucky i am respecting the rules of this forum in a no hold barred setting i would put your leftist nothingness in your place.
you are nothing , and you are just a liberal and media puppet.
