Global warming is a fact!

Quote from dcraig:

These are the peak bodies of world science. You know, the science that modern civilization is built upon.

Perhaps, but I'm willing to bet if these mental lemmings keep asserting the fallacy of authority position they will be mocked for centuries just as heated arguments over the number of angels dancing on pinheads.

I'll ask you what risk does gw pose?

Sea level rise, destruction of biodiversity, destruction of productive capacity of farmland, some inhabited areas becoming literally so hot that humans cannot exist there, regional temperature and rainfall changes far exceeding the global average.

During the horrendous bushfires in Australia in the last couple of years, temperatures reached 48C (118.5F) in south east Australia. A few more degrees and it is for practical purposes uninhabitable.

And then there is the other CO2 problem - ocean acidification. The oceans are already 30% more acidic than in pre-industrial times. Higher temperatures and increased acidity are a major threat to coral reefs, anything with a shell etc etc.

Worst case (which cannot be ruled out) is runaway greenhouse effect with massive release of methane from tundra and sea beds. In such a scenario, the temperature rise cannot be stopped even if humans cut GHG emissions to zero. How likely? Nobody knows. Which is a very good reason not to break things that are not fully understood when the stakes are so high.

What makes your fellow morons think they can control planetary temperature in the first place?

You misunderstand the nature of science. Science does not depend on proof. Mathematics depends on proof. Science depends on evidence. And the evidence for AGW is overwhelming. It ranges from the basic physics of GHGs, the measured radiative imbalance of the earth (more energy in than out), the statistically significant trend in global surface temperature, the statistically significant trend of increasing ocean heat content, the shrinking glaciers, polar ice and Greenland ice sheet, the compelling evidence of the major role of CO2 in regulating temperature from studies of the earths past climate, the highly accurate measurement of the increase of atmospheric CO2 and the isotopic studies showing the increase to be of human origin.

Most of all, there is no other feasible explanation for the rapid rise in temperature. And other possible causes have been exhaustively examined. It's not the sun - it's the coolest in a century. It's not cosmic rays. It's not ENSO. etc etc.

You can choose to assert that the evidence is not convincing, but that is not the conclusion of expert scientific opinion. Any rational person will go with the science, especially when the risk is so high.

My point was that this article, ALONE, does not = "Global warming is a fact!" as the TC stated.

As to the rest of your post, we have already had this argument, and I just wrote out a long ass response that I accidentally deleted, so it willl have to wait till tomorrow.
 
Scientists made up data. It really is that simple.

The monkey business arose from the need to use data collected over time by different technical means. Each of these data sets has their own individual biases due to the measurement method, placement of sensors etc.

Somehow the data needed to be normalized so that it could be used as a data super-set for expressing extremely long term trends.

Here is were the fraud occured. Normalization requires some assumptions and these assclowns made every assumption break in their direction. They almost always assumed that temp sensors were under-reporting when in reality the biases are more gaussian.

They cooked the books. A child could spot it.
 
All this explains how the earth is warming, and i will not oppose such evidence, where is the link that we are causing this? That is my only question, and once you provide me with "said" evidence i will not question it anymore.

One of the foundations AGW is that man produces CO2, the consequent rise in CO2 causes the earth to warm. So you would expect to see CO2 levels rise BEFORE temps rise. But quess what? The historic data shows the exact opposite, sometimes by hundreds of years.

Then there is the matter of the "Hockey Stick". But quess what? Dr Mann overweighted tree ring data that showed temps rising and ignored tree ring data that showed temps stable to declining. Why would he do that?

This image, which became the favored icon of global-warmists, has taken on a life-of-its-own during the past decade. The hockey-stick icon has already cost taxpayers billions of dollars and has the potential to cost taxpayers and consumers trillions more. When Michael Mann created the temperature dataset that the hockey-stick graph is based on, little did he realize that trillions were at stake, or that he would unleash a science-fraud tsunami that now threatens to legally engulf him. (click on images to enlarge)

The Mann icon was relentlessly published by the IPCC (until being mathematically and statistically discredited) because it showed modern temperatures to be significantly higher than past temperatures - in the vernacular of the "hockey stick", its 20th century "blade" was way above the "handle" of the stick. Prior to Mann's research, the IPCC had no unprecedented "blade" to proselytize with, so to speak.

So, how did Mann manage to find a modern, huge warming "blade" that others had missed in the historical temperature proxies, such as tree rings? Ahhhh, the beauty of using unique, but questionable mathematical/statistical techniques, that can often produce very artful science.



Mann's methodology, as outlined by one of the experts who tore it asunder, was relatively simple. First, one designs software code to search through thousands of tree ring data records. The objective is to identify those tree ring series that display exceptional growth during the 20th century (see top panel for Sheep Mountain tree rings). Second, once those exceptional tree ring records are identified, design your programming to over-weight those exceptional records by 390 times. Third, ignore the majority of tree ring records (see bottom panel for Mayberry Slough tree ring example) that reveal non-exceptional growth for the 20th century. Fourth, attribute 100% of exceptional tree ring growth to warming temperatures, not to other critical tree growth factors such as water, CO2 and soil nutrients.

And, voila, one can magically produce a very pronounced "blade." And like a true magician (unlike a true scientist), one never tells how the trick was done. As it turns out, it is the last sentence that has really been Michael Mann's undoing. Instead of openly sharing all the data and software coding he used to produce his results, so that other scientists could attempt to replicate his work, he chose not to cooperate with experts. To this day, he still has not released all the data/software evidence that he based his research on. As a result, many are now concluding that the original hockey-stick chart was based on scientific fraud, and that similar subsequent research by others is highly suspect also.

Because the science institutions, the peer-review journals, the universities and, most importantly, the IPCC climate scientists all failed in their identifying and correcting Michael Mann's methodologies from the beginning, he now finds himself in the legal, shark infested waters. When others miserably fail to perform their responsibility, the legal community will gladly do so for them.

For a good basic review of Ross McKitrick and Steve McInytre's effort to analyze Mann's hockey-stick research, read this. I can highly recommend A.W. Monford's, The Hockey Stick Illusion: Climategate and the Corruption of Science. It provides an insight to climate science that is incredibly damning and fascinating at the same time.
