I know, I know... you're all getting tired of hearing about global warming. But this subject is just too important to let it go. Just like with the Vietnam war, where the mainstream media (MSM) told us one thing, but the truth was something different, you'll think that human activity is solely responsible for global warming if you listen solely to the MSM. While no one here at the LTS is a scientist, and certainly I am not, we remain skeptics (if you haven't already figured that out) on the subject.
It would be so much easier to simply shut up and go along with the mainstream view on this, but I get very suspicous of 'coincidences'. The fact that those who see humans and our capitalistic society as evil and wrong now have this convenient tool to use to try to bring down all that we have built. That is just too coincidental for me. I don't know for sure that global warming isn't caused by human activity, and it seems logical that we contribute to it.
For that matter, if anyone wants to have a discussion on ways to cut the levels of pollutants we put into the environment, I am ready. I want a clean environment as much as anyone, but it should be done in a reasonable and responsible way. To try to shout down opposition to the prevailing view of the causes of global warming, as it seems so many are want to do is irresponsible at the least. To not question the veracity of science is also irresponsible. Many scientists in the field of climate change DO question the veracity of the prevailing view, and part of our purpose here at the LTS is to try to bring those points of view into focus.
Once such view we saw recently supports our skepticism: (Via Greenie Watch)
At a recent global warming conference in Exeter called by UK prime minister Tony Blair, all the usual fears were aired. Yet real debate about climate change seems to be strictly prohibited.
The week before, another conference organised by the Scientific Alliance at London's Royal Institution raised critical questions about the global warming thesis. This time the Royal Society's president Sir Bob May received frontpage coverage for arguing that the event would be biased and dangerous.
'On one hand we have the IPCC [Intergovernmental Panel on Climate Change], the rest of the world's major scientific organisations, and the government's chief scientific adviser, all pointing to the need to cut emissions', he wrote. 'On the other we have a small band of sceptics, including lobbyists funded by the US oil industry, a sci-fi writer, and the Daily Mail, who deny the scientists are right. It is reminiscent of the tobacco lobby's attempts to persuade us that smoking does not cause lung cancer. There is no danger this lobby will influence the scientists. But they don't need to. It is the influence on the media that is so poisonous.' (1)
But in fact, those labelled 'sceptics' and those regarded as 'mainstream' actually share much in common. Professor Richard Lindzen of Massachusetts Institute of Technology (MIT), usually regarded as a sceptic but also a lead author for the IPCC, agrees that there is consensus among scientists. That consensus is as follows:
1. While there are inconsistencies in the temperature data, it is very likely that the world has got a bit warmer over the past 100 years - 0.6 degrees Celsius, on average, give or take 0.2 degrees either way.
2. That carbon dioxide is a greenhouse gas. The more carbon dioxide in the atmosphere, the warmer the world will tend to get.
3. That human activity has led to a significant increase in carbon dioxide levels, from 280 parts per million in the centuries before 1750, to 380 parts per million now.
4. Economic trends will tend to further increase carbon dioxide levels - so it is very plausible that the world will get warmer in the coming decades, all other things being equal.
