This is what I hear too. Among the scientific community there is very little debate about the fact that Global warming is happening, AND THAT IT IS MAN MADE.
BUT...
The problem seems to be that there is a growing number of people denying that it is either happening or that man is causing it. High profile environmentalist David Bellamy, for example, who's a botanist and not a climatologist for the record, denies that its a problem...and says that it's even a good thing.
As far as Hydrogen goes as an alternative fuel. What I also hear is that its a bit of a scam. You have to burn a lot carbon just to produce one fuel cell?
As far as alternative energy sources are concerned in general, a lot of scientists are saying that it's just not going to be enough to maintain our current rate of consumption THERFORE we will have to turn go NUCLEAR as a sort of stop gap measure before alternative sources become viable. OR we will have to reduce consumption, THIS ESSENTIALLY MEANS JOB LOSSES AND REDUCED LIVING STANDARDS, just for those who only think in terms of modern economics.
On Kyoto, the main problem that countries who refuse to sign Kyoto (Australia and USA) have with the treaty is that it doesn't require growing economies to reduce their greenhouse gas emissions as much as 1st world countries. The retort from these growing economies is that the western industrial countries are the biggest polluters as far as Greenhouse gas is concerned. They have basically used up Earths Green-house gas credit limit themselves and profited very nicely from their use. Growing economies are p*ssed off that they don't get to profit from greenhouse gas use like the west has, and instead have to shoulder the same burden as western countries as far as reducing green house gas emissions are concerned. The US and Australia(countries that refuse to sign Kyoto) are just being selfish is what it breaks down to. They are too concerned about maintaining their market dominance over growing economies.
