As somebody previously commented - 95 percent of climate change scientists insist that we are closely at the tipping point of an irreversible change to the planets climate.
In Britain the government's scientific adviser Sir David King, hardly your typical left-winger, agrees that we are at the point of irreversible catastrophe unless we reduce global carbon emissions by 90 percent by 2020.
The UN's recent report confirms that climate change is a reality. The IPCC report by the world's leading climate change scientists also say it is happening, as did the Stern report here in the UK.
Yet we have ill-informed people, who have never had a peer-reviewed scientific paper published on the subject, claiming the contrary. I refer to this as "the Gallileo syndrome."

Can someone explain something that has bothered me. Algore writes a book with a claim, and then thousands of scientists crawl out of the woodwork saying "Duh, yeah, he's like right!". Where were all these guys before algore came along? Sleeping on the job?? |
They were saying that before, actually.
You just hadn't heard, I guess? |
Yeah sure they were. And they were issuing UN reports, too?  Care to cite one? |
How about the 1990 First IPCC Assessment Report, or the Second Assessment Report in 1995, or the Third Assesment Report in 2001. |
You're wrong.
From the 1990 assessment:
Quote:
There are many uncertainties in our predictions particularly with regard to the timing, magnitude and regional patterns of climate change, due to our incomplete understanding of: sources and sinks of GHGs; clouds; oceans; polar ice sheets.
Our judgement is that: global mean surface air temperature has increased by 0.3 to 0.6 oC over the last 100 years...; The size of this warming is broadly consistent with predictions of climate models, but it is also of the same magnitude as natural climate variability. Thus the observed increase could be largely due to this natural variability; alternatively this variability and other human factors could have offset a still larger human-induced greenhouse warming. The unequivocal detection of the enhanced greenhouse effect is not likely for a decade or more.

Give me a break and admit you are wrong. The 1991 assessment was very conservative. The 95 and 2001 assessments all say that global warming is highly likely to have been caused by humans.
If you think that scientists just came out of the woodwork when Gore wrote his book you just haven't been paying attention. |
The issue wasn't did scientists come out of the woodwork - don't try to escape your false statement by flipping the issue - I said why are the scientists NOW saying he's right, you cited the other reports as if they had already been saying it, and they DON'T agree with Gore's claims - just as I said. |
