Are we "wacky" because we don't just dismiss this stuff?
Some info I just read from
the dimming faq:
What's the range in the figures on global dimming? Is there a consensus or are they as open to interpretation as global warming figures?
I don't think the figures on global warming are open to interpretation. It is an established fact that global temperatures have risen by 0.6°C over the past century. It is also an established fact that carbon dioxide levels have risen by about 100 parts per million over the same period due to human activity. It is a matter of the basic laws of physics that an increase in carbon dioxide will trap more heat in the Earth's atmosphere, which is why almost no respectable and independent scientist doubts the causal link between these two established facts.
The only surprise is that the warming has not been greater - which is where global dimming comes in. Unfortunately, there is still a very large range in the estimates of the cooling effect of dimming - by up to a factor of four. What seems to have been established already, however, is that the cooling effect of dimming is far larger than previously thought. This may explain why the world has not already warmed more strongly - the cooling effect of particle pollution has been offsetting the warming from carbon dioxide. If so, then we are in for far faster warming in the future as particle emissions are brought under control while greenhouse gas emissions continue to rise.
I think this doesn't mean "if we stop using fossil fuels, the climate will really heat up".. If I am interpreting this correctly it means if we reduce particle emissions but continue using up fossil fuels, the climate will really heat up. So the best thing to do is reduce all emissions.
Thats probably a good idea regardless of whether this current theory is correct. On that:
Are scientists often sceptical of findings that go against the current orthodoxy?
Yes, for good reason - usually the orthodoxy is correct. A famous physicist once told me that if you doubt every new idea in science you will be right 90% of the time, but you will be wrong the only time it matters.
