That doesn't mean that it's not feasible, [...] it will take time and money and at the moment there are too many vested interests (especially at the heart of the US Government!) for much to change.

That's how I understand it too. But I think the process is a lot more advanced than we realise, and nearer to fruition. Apparently there is a already a hydrogen filling station at one of the German airports? Also, a lot of the big car manufacturers are piling money into R&D; this link shows a ew of them: |
Yes, there are hydrogen powered cars being developed and, yes, there are a few places where you can "fill up", but compare that to the amount of money that's being spent on petrol/ diesel powered cars etc and it practically pales into insignificance.
Also, of course, that site is dedicated to pitching hydrogen as an alternative, so naturally they'll put the best spin on it that they can.

[QUOTE=CJU]They are now saying thanks to global warming in the next few years cod in the british waters will become extinct
"Now saying"?
This report is from 2001.
"Global warming could be tearing apart the delicate marine food chain - spelling doom for everything from zooplankton to dolphins, "
This report points out that UK waters are the most southerly limit of many fish species and it will only take a slight rise for them to no longer swim down as far as they do now.
"Some of the colder-water fish species that people like to have with chips are at the southern limit of their range, and if the warming trend continues, cod are likely to become extinct in the North Sea in the next few decades."
"This year stocks of young cod were at their lowest for 20 years. The numbers of wild salmon have almost halved over the past two decades and this year the numbers returning to British rivers to spawn fell to a record low. Meanwhile, warm-water fish such as red mullet, horse mackerel, pilchards and squid are becoming increasingly common."
And the fact is that cod fishing in the North Sea is no longer viable due to massive over-fishing and it is now "commercially extinct".

What lengths are they willing to go to get the point across that global warming is a hazard that has been left to long
|
I'm sorry, by "what lengths" are you implying that they are lying to try to make this point?

But unless you have a severe problem with nuclear power, this isn't a problem. Radioactive material, whilst not recycleable nor renewable, is in such plentiful supply, it is more than feasible for long-term use. |
And then leaves pollution for *thousands* of years. What a wonderful legacy...!!
