C'MON Man!! Everybody knows that Global Warming is from all of those "COW FARTS"!!

I didn't watch all two hours you posted but I noticed the man who is the professor at Alabama mentioned that the perceived warming is the result of taking measurements from urban centers. This applies to that point:

"1. EVIDENCE THAT THE EARTH'S TEMPERATURE IS GETTING WARMER IS UNCLEAR

Sceptic

Instruments show there has been some warming of the Earth's surface since 1979, but the actual value is subject to large errors. Most long-term data comes from surface weather stations. Many of these are in urban centres which have expanded in both size and energy use. When these stations observe a temperature rise, they are simply measuring the "urban heat island effect". In addition, coverage is patchy, with some regions of the world almost devoid of instruments. Data going back further than a century or two is derived from "proxy" indicators such as tree-rings and stalactites which, again, are subject to large errors.

Counter

Warming is unequivocal. Weather stations, ocean measurements, decreases in snow cover, reductions in Arctic sea ice, longer growing seasons, balloon measurements, boreholes and satellites all show results consistent with the surface record of warming. The urban heat island effect is real but small; and it has been studied and corrected for. Analyses by Nasa for example use only rural stations to calculate trends. Recently, work has shown that if you analyse long-term global temperature rise for windy days and calm days separately, there is no difference. If the urban heat island effect were large, you would expect to see a bigger trend for calm days when more of the heat stays in the city. Furthermore, the pattern of warming globally doesn't resemble the pattern of urbanisation, with the greatest warming seen in the Arctic and northern high latitudes. Globally, there is a warming trend of about 0.8C since 1900, more than half of which has occurred since 1979."

Since it appears you like the BBC as a source of info. Here is a documentary produced by the BBC that interviews many true scientists that are or were on the IPCC, some even had to sue the IPCC to get their names off of the list of authors because they didn't agree with what the IPCC had published.

I've seen it. Obviously, some other knowledge must have trumped that video. I'm posting simple point counterpoints since it's easier to dig through and understand for a layperson as a concept. The type of data I look at isn't even comprehensible to a person with no training in the applicable fields of science (Geology in my case). I'm not writing here for a published work. I am merely pointing out that the naysayers in rural Kansas do not represent the entire spectrum of opinions on this issue. For what it's worth, there are plenty of youtube videos with quasi-science in them. There is a great one in particular about Earth growing in size.

The vocal minority of scientists are just those two things.

Another concept:

"Objection: According to the IPCC, 150 billion tonnes of carbon go into the atmosphere from natural processes every year. This is almost 30 times the amount of carbon humans emit. What difference can we make?

Answer: It's true that natural fluxes in the carbon cycle are much larger than anthropogenic emissions. But for roughly the last 10,000 years, until the industrial revolution, every gigatonne of carbon going into the atmosphere was balanced by one coming out.

What humans have done is alter one side of this cycle. We put approximately 6 gigatonnes of carbon into the air but, unlike nature, we are not taking any out.


Thankfully, nature is compensating in part for our emissions, because only about half the CO2 we emit stays in the air. Nevertheless, since we began burning fossil fuels in earnest over 150 years ago, the atmospheric concentration that was relatively stable for the previous several thousand years has now risen by over 35%.

So whatever the total amounts going in and out "naturally," humans have clearly upset the balance and significantly altered an important part of the climate system."
