The Global Warming Heretic
theodp writes "In The Civil Heretic, the NYT Magazine takes a look at how world-renowned scientist Freeman Dyson wound up opposing those who care most about global warming. Since coming out of the closet on global warming, Dyson has found himself described as 'a pompous twit,' 'a blowhard,' and 'a mad scientist.' He argues that climate change has become an obsession for 'a worldwide secular religion' known as environmentalism. Dyson has been particularly dismissive of Al Gore, calling him climate change's chief propagandist and accusing him of relying too heavily on computer-generated climate models and promoting 'lousy science' that's distracting attention from more serious and more immediate dangers to the planet."
Dyson himself wrote about the need for heretics in science not long ago.
You know he actually was quoted saying "I am not going to let science get in the way"...
Googling 'gore "I am not going to let science get in the way"' returns 0 results.
Eagles may soar, but weasels don't get sucked into jet engines.
that's because 'global warming' is a badly chosen term. the average temp may go up, but lots of places are going to get colder, hotter, drier, wetter for longer periods.
Yes, I'm left. You have a problem with that?
Following a few links from googling 'gore "not going to let science get in the way"' led me to this: http://www.dailytech.com/article.aspx?newsid=13773. Seems he did say something of the sort, anyway.
First off I want to say Freeman Dyson is a brilliant physcist and we should all be grateful for his work in physics, he is not however a climate scientist, climate scientists have a rather different view of the whole thing:
"IPCC is not alone in its conclusions. In recent years, all major scientific bodies in the United States whose members' expertise bears directly on the matter have issued similar statements. For example, the National Academy of Sciences report, Climate Change Science: An Analysis of Some Key Questions, begins: "Greenhouse gases are accumulating in Earth's atmosphere as a result of human activities, causing surface air temperatures and subsurface ocean temperatures to rise" [p. 1 in (5)]. The report explicitly asks whether the IPCC assessment is a fair summary of professional scientific thinking, and answers yes: "The IPCC's conclusion that most of the observed warming of the last 50 years is likely to have been due to the increase in greenhouse gas concentrations accurately reflects the current thinking of the scientific community on this issue" [p. 3 in (5)].
Others agree. The American Meteorological Society (6), the American Geophysical Union (7), and the American Association for the Advancement of Science (AAAS) all have issued statements in recent years concluding that the evidence for human modification of climate is compelling (8).
The drafting of such reports and statements involves many opportunities for comment, criticism, and revision, and it is not likely that they would diverge greatly from the opinions of the societies' members. Nevertheless, they might downplay legitimate dissenting opinions. That hypothesis was tested by analyzing 928 abstracts, published in refereed scientific journals between 1993 and 2003, and listed in the ISI database with the keywords "climate change" (9).
The 928 papers were divided into six categories: explicit endorsement of the consensus position, evaluation of impacts, mitigation proposals, methods, paleoclimate analysis, and rejection of the consensus position. Of all the papers, 75% fell into the first three categories, either explicitly or implicitly accepting the consensus view; 25% dealt with methods or paleoclimate, taking no position on current anthropogenic climate change. Remarkably, none of the papers disagreed with the consensus position."

So do some research about the mainstream of climatology before jumping on the Dyson bandwagon.
And yes Al Gore is often an exaggerated propagandist and he isNOT helpful in this debate, that doesn't however mean that there isn't real climate science out there pointing to the anthropogenic origin of observed climate change.
Tired of all the isms, don't exploit people as an employer, or a government, mmmmK?
MYTH 1: Global temperatures are rising at a rapid, unprecedented rate.
FACT: Accurate satellite, balloon and mountain top observations made over the last three decades have not shown any significant change in the long term rate of increase in global temperatures. Average ground station readings do show a mild warming of 0.6 to 0.8C over the last 100 years, which is well within the natural variations recorded in the last millennium. The ground station network suffers from an uneven distribution across the globe; the stations are preferentially located in growing urban and industrial areas ("heat islands"), which show substantially higher readings than adjacent rural areas ("land use effects").
There has been no catastrophic warming recorded.
MYTH 2: The "hockey stick" graph proves that the earth has experienced a steady, very gradual temperature decrease for 1000 years, then recently began a sudden increase.
FACT: Significant changes in climate have continually occurred throughout geologic time. For instance, the Medieval Warm Period, from around 1000 to 1200 AD (when the Vikings farmed on Greenland) was followed by a period known as the Little Ice Age. Since the end of the 17th Century the "average global temperature" has been rising at the low steady rate mentioned above; although from 1940 Ãff" 1970 temperatures actually dropped, leading to a Global Cooling scare.
The "hockey stick", a poster boy of both the UN's IPCC and Canada's Environment Department, ignores historical recorded climatic swings, and has now also been proven to be flawed and statistically unreliable as well. It is a computer construct and a faulty one at that.
MYTH 3: Human produced carbon dioxide has increased over the last 100 years, adding to the Greenhouse effect, thus warming the earth.
FACT: Carbon dioxide levels have indeed changed for various reasons, human and otherwise, just as they have throughout geologic time. Since the beginning of the industrial revolution, the CO2 content of the atmosphere has increased. The RATE of growth during this period has also increased from about 0.2% per year to the present rate of about 0.4% per year,which growth rate has now been constant for the past 25 years. However, there is no proof that CO2 is the main driver of global warming. As measured in ice cores dated over many thousands of years, CO2 levels move up and down AFTER the temperature has done so, and thus are the RESULT OF, NOT THE CAUSE of warming. Geological field work in recent sediments confirms this causal relationship. There is solid evidence that, as temperatures move up and down naturally and cyclically through solar radiation, orbital and galactic influences, the warming surface layers of the earth's oceans expel more CO2 as a result.
MYTH 4: CO2 is the most common greenhouse gas.
FACT: Greenhouse gases form about 3% of the atmosphere by volume. They consist of varying amounts, (about 97%) of water vapour and clouds, with the remainder being gases like CO2, CH4, Ozone and N2O, of which carbon dioxide is the largest amount. Hence, CO2 constitutes about 0.037% of the atmosphere. While the minor gases are more effective as "greenhouse agents" than water vapor and clouds, the latter are overwhelming the effect by their sheer volume and Ãff" in the end Ãff" are thought to be responsible for 60% of the "Greenhouse effect".
Those attributing climate change to CO2 rarely mention this important fact.
MYTH 5: Computer models verify that CO2 increases will cause significant global warming.
FACT: The computer models assume that CO2 is the primary climate driver, and that the Sun has an insignificant effect on climate. You cannot use the output of a model to verify or prove its initial assumption - that is circular reasoning and is illogical. Computer models can be made to roughly match the 20th century temperature rise by adjusting many input parameters and using strong positive feedbacks. They
Another non-climate-scientist who thinks nearly all of the climate scientists are wrong about the climate.
You're off there. In fact, in the article you linked to on the very same page, you see that he has published at least one paper in the field. Sure, his main field is physics, but how long does it actually take to become an expert in a field? By the time you're his age, you've had enough time to expand into a lot of areas.
Dyson seems well aware that the climate is, in fact, warming.
Did you actually spend any time figuring out what he does claim? Once again, in the first paragraph of the article you linked to, Dyson states his opinion "[Global warming] is a real problem, but it's nothing like as serious as people are led to believe. The idea that global warming is the most important problem facing the world is total nonsense and is doing a lot of harm."
Dyson's wrong to repeat the "global cooling" myth
He was actually there in the late 60s. I had a textbook that talked about global cooling, and gave possible solutions. Indeed, there is no reason to doubt that eventually we will enter into another ice age. The paper linked to in your link basically outlines the path scientists made from thinking in terms of ice ages, solar forcing, etc. to becoming aware of the consequences of human interaction on the global climate. It shows convincingly that in those days no one was worried about immediately entering into an ice age. However, it doesn't contradict, and in fact confirms, that there was a general consensus that we would eventually enter another ice age.
Basically you're a troll who didn't even read your own articles. And a slashdot editor. Wow, should that be a surprise?
Qxe4
Near record is not a record. Cherry pick your quotes much? Next sentence in that article:
"but 34 percent below the average measured for September since 1979"
Last year was a record. 9% back from that record compared to last year is still crappy when you're talking about a total 34% drop in total area since 1979. 4.5227 million square miles compared to 4.6 million square miles year to year change from 2007 to 2008, compared to over 6 million square miles three decades ago. The article could be a little less hyperbolic in it's title, but as for an agenda? Please.
He's not saying they're *wrong* about climate change, he's saying it's nowhere close to the most important problem we face as a human race. Which I personally agree with.
I'm sure Slashdot editors have some kind of automatic +5 ranking, but please at least *read* the article before spreading bullshit on your own forum.
