The American Denial of Global Warming



Uploaded by: uctelevision
Video Description:
Polls show that between one-third and one-half of Americans still believe that there is "no solid" evidence of global warming, or that if warming is happening it can be attributed to natural variability. Others believe that scientists are still debating the point. Join scientist and renowned historian Naomi Oreskes as she describes her investigation into the reasons for such widespread mistrust and misunderstanding of scientific consensus and probes the history of organized campaigns designed to create public doubt and confusion about science. Series: "Perspectives on Ocean Science" [12/2007] [Science] [Show ID: 13459]

The sources are not as diverse as you believe them to be, and there isn't a universal recognition of anthropogenic warming. Also, both, physics and chemistry apply to the relationship between CO2 and temperature. Economic damage isn't linked to global warming, and you are making claims that have not yet been proven. You are discussing the affects of something that has not been proven to be the result of mans' actions.

Madehero - Anthropogenic warming is obviously argued about on YouTube, but my point was that it's universally recognized in the science literature, without exception, based on extensive evidence found in the journals. The logarithmic CO2/temperature relationship is a physics phenomenon, well established in the literature, but if you don't have access to the journals, Google "Saturated Gassy Argument", and read parts 1 and 2 for the physics - related to lapse rate effects and band broadening.

Why is the not a single person who can explain how Temperature rises 700-1000 years BEFORE CO2 levels, and FALLS 700-1000 years BEFORE CO2 levles, throughout ALL of the 1,000,000 years of recorded Ice Core data?
The direction of causality is simply ignored by the MMGW crowd. But there is no possible way that CO2 has caused the Earth's temperature rise. The current CO2 rise is due to the TEMPERATURE rise of 700-1000 years ago.
Check out the medieval warming period.

grastog, sorry to burst your bubble, but there is a FAR stronger correlation of temperature with Sun Spot activity than man-made CO2 concentrations. The politics of Global Warming Hystery is clearly documented to be socialist in origin and half-assed in it accuracy and data.
Follow the money. If you want funding, you bow to AGW.

Texas:
The lag between CO2 and temperature has to do with sequestered CO2, which is generally given off by vegetation 70 to 80 years after temperature begins to rise. Our alkaline oceans absorb much of the planet's CO2, and begins releasing the CO2 as temperatures rise. The oceans are responsible for a 700 year lag between temperature and CO2.

grastog:
I know that it is argued about on youtube, but my point was that it is also discussed/debated within the scientific community. I would also like to know what "journals" contain "extensive" evidence. You can claim that the relationship between CO2 and temperature is solely physically based, but that wont change the fact that chemistry plays a role as well. You also need to realize that "saturation" is based on many factors, one of which is the chemical/molecule itself.

'given the human and economic devastation already experienced by recent warming - floods, excess hurricane deaths, crop failures, and impoverishment, among other afflictions.'
100's of 1000s of log books are being analyzed from shipping in the 16th,17,18th centuries thy show no differences from the weather then and the weather now, if anything worse then, difference is we can cope better now, with better crops, only problem is where man chooses to live. don't build houses on water meadows.

madehero,
The sequestration process is completely overlooked by the dweebs who think Global Warming is man-made, or even influenced.
The direction of causality in the real universe is that if A is 'possibly' the cause of B, then A MUST occur BEFORE B. Not EVERY event before B causes B. But ANY event that DOES cause B MUST occur BEFORE B.
CO2 NEVER rises in advance of temperature rise in the historical data. CO2 therefore CANNOT be the cause of the Earths global climate cycles.

grastog, if you paid attention to the last American election, you would realize that the medias willingness to report a story is clearly correlated with its alignment with their liberal political agenda.
This includes so-called peer-review scientific journals. Scientists are no less subject to their bias and fear of opposing opinions. And Global Warming science at this point, is subjective opinion. The magic phrase is 'determined by consensus'.

Texas - you've made some misstatements that sugggest to me you're unfamiliar with the scientific evidence in general, or the evidence for the CO2/temperature relationship in particular. CO2, both in modern times and prehistory, has always exerted a warming influence, even when some other factor such as orbital forcing initiated the warming, which was then followed by CO2 and its own warming. For examples, see Royer, Nature 446:530, 2007, and Ahn, Science 322:83, 2008. It's not controversial.

Texas:
That is a common fallacy though. We may not know what causes the initial temperature increase, but CO2 does magnify the initial temperature increase. It is a series of cycles, not just a one step process. However, people don't realize that the claim of man causing global warming is a fallacy as well. They also ignore the fact that most people pushing the theory only claim an accuracy of approximately 80%, and a range of error as high is 20% is outstanding for the scientific community.

made,
Imagine an insulating layer around the Earth. This is the whole crux of the 'green house' warming theory. The CO2 captures and collects the radiant energy from the Sun and therefore, causes Temperature to rise.
The CO2 may ONLY act as a collector if the Sun is producing energy at the same, or higher, rate. IF the green-house warming theory were accurate, once elevated, the temperature could ONLY go up, while a constant solar energy was input into the system.
That just has not happened.

grastog, please do not mistake rejection of unfounded and speculative concepts with unfamiliarity. This is the logical error most pseudo-intellectuals make.
Feel free to address the direction of causality, whereby Temperature rises and falls 700-1000 years before the matching CO2 change, and the proposed or assumed mechanism CO2 employs to mystically affect Temperature 700-1000 YEARS before the lagging change.
Rational people can readily see that CO2 cannot possibly be the Temperature driver.

Texas:
I know the factors affecting the planets climate/temperature. There are many different things that affect temperature, and CO2 is one of them. However, people claiming that man is responsible for global warming choose to ignore the cycles of the Earth and sun. If you monitor solar cycles, then you can see why temperature eventually begins to fall.
madehero - Climate ... ( 11 hours ago by grastog1313)
madehero - Climate science doesn't ignore solar and other effects, but they are small compared with anthropogenic CO2 emissions in driving warming over the past 100 years (Google "Lean Rind 2008" for one paper out of hundreds documenting the predominance of CO2). I've already cited other sources among the many showing that rises in CO2 have always exerted a warming effect throughout the billions of years of prehistory. Readers should review them, and can draw their own conclusions.

made, I actually agree that CO2 has a potential effect to contribute to the warming of the Earth.
I think the current hysteria regarding man-contributed CO2 is largely a subterfuge for attacking capitalism and Western Civilization, whether consciously or subconsciously.
With Sun Spot cycle 24 having bee so late, it will be interesting over the next 5-10 years to see whether the cooling is sufficient to gather the attention of the 'warming-only' crew.
grastog, that is ... ( 11 hours ago by Texas75023)
grastog, that is fundamentally where you are in error, my friend. anthropogenic, or man-contributed CO2, is so far below other effects as to defy actual measurement.
The cold fact is that CO2 has no memory of who released it, or how. Natural sources do not mark the molucules for later conspiratorial collection of the anthropogenic atoms into evil roaving gangs.
You need only look at eGore's stage wide curve to see that WITH CO2 at it's peak, Temperature gleefully falls 700-1000 years B4 CO2.

Well, we have been seeing minor temperature increases and decreases lately. We have been coming out of an ice age for quite some time, and we will continue to see oscillations in temperature until we begin to enter the next ice age, which should occur recently.

I've already provided references regarding the predominance of anthropogenic CO2 emissions in recent global warming (Lean Rind 2008), as well as Royer (Nature) and Ahn (Science) for data documenting that CO2 has always exerted a warming effect. Given disagreements here, it would be worthwhile for interested viewers to read these to draw their own conclusions. (For those interested in logical fallacies, consider Texas's claim - warming can increase CO2, therefore CO2 can't cause warming. Logic?)
madehero - It's ... ( 11 hours ago by grastog1313)
madehero - It's incorrect to state that we've been coming out of an ice age. We've been in the Holocene Interglacial for 11,000 years, with some ups and downs, but basically a flat temperature. The "Little Ice Age" (not really an ice age ended many decades before anthropogenic warming began around 1910 (the earlier decades showed no trend). A new glaciation is possible, but based on orbital parameters, is at least 30,000 in the future.

I realize this isn't the place for details underlying CO2-driven warming physics. Texas and others without a science background can Google "Greenhouse Effect" for some good basics, while those with a strong science background should Google "Climate Book". Still, an important misconception by Texas should be dispelled to avoid confusing others. CO2 does not absorb solar radiation, but only infrared emitted from the Earth and atmosphere, and the absorption therefore occurs both night and day.
