I'm not sure you meant to write 'if CO2 dominated the atmosphere' but I know what you mean and you're right of course about trying to live in earlier environments in the way we do now.

Re: Global Warming... a hoax?
The Earth has been through extremes to get where it is from an atmosphere of ammonia, hydrogen cyanide, methane and carbon dioxide came RNA and DNA (nobody know how but it just did) and the evolution of early plant and bacterial life. Stromolites' were probably the key as the first lifeform to kick enough oxygen into the atmosphere to overcome oxidization by iron and then cyanobacteria (which absorbs CO2) played an important part in stabilizing the atmospheric gasses to form the ratio's we have today - et-voila a stable biorb in which life can crack on and evolve. As the ratio of those gasses continues to change life will evolve and technology will adapt, something will survive, however the question in all of this is really: are we in a position to engineer the earth and maintain (roughly) the balance we have today, so can we and should we?

News item on variations in ocean CO2 uptake.
http://news.bbc.co.uk/1/hi/in_depth/...om/8390388.stm
Which shows that assumptions about the oceanic absorbtion are just that-assumptions.

Re: Global Warming... a hoax?
So what are you saying, the oceanic absorption rate is an assumption or that there are assumptions in the theory?

Re: Global Warming... a hoax?
Assumptions in the theory. I'm aware of a lot of this, but no expert, but I was interested to see the comment in the report that half of atmospheric Co2 goes to the sea, and the rest to land. Given that 70% of the planet is water, much of which is full of O2 generating algae, carbon snaffling corals and so on, I was expecting a larger proportion to go to the oceans. If the oceans are overloading, then presumably thats because the land mass is absorbing less- Which suggests that more deforestation might be a bit of a silly idea.

Re: Global Warming... a hoax?
But why do you need a tenuous man-made global warming argument to conclude that we should put a brake on deforestation and how does it help restore the forests by devoting time and effort to carbon trading agreements?

Re: Global Warming... a hoax?
Just used the BBC "listen again" to hear Jeremy Vine (spit!!!!) on this.
He was very gentle on both sides for once, including the last caller who seemed to be pointing out something about of course sea levels are rising - we're all flushing the toilet more than we used to and where do we think all that water goes?
:D

I presume you've interpreted my post as calling you personally an evangelist SWW? For clarity, I didn't.

Climate scientists and the Milliband idiot standing there and insisting that anybody who is a "denier" is too stupid to understand the issue is just going to alienate the silent majority.
I fully accept that all sides have a their own interests, I've made my own feelings on energy security perfectly clear on many occasions and agrre with you.
As for which side loses, I strongly disagree with you, current eco-madness means we are all going to lose.
Copenhagen isn't going to help the planet, it isn't going to change the climate but it is ging to cost us all a fortune. There are no winners out of this mess.
We could apply logic and common sense but we aren't going to get that are we?
Sensible energy usage and generation I'm all in favour of, how is taxing my Land Rover going to change that?
All we have achieved to date is to create a half baked theory on environment change and punitive policies from government designed to exploit fear of that climate change to generate revenue.
If there was real concern about climate change then we would be approaching the whole thing very differently.

Re: Global Warming... a hoax?
Open question to the believers in global warming:
What happened to the mid 1970 claims that we were about to freeze to death? After all the Earths temperature was going to fall by 6C, The nitrogen in the atmosphere would increase to near death levels?
There is no such thing as independent science. Scientists are no different to actors, they both have massive ego's to massage.

Re: Global Warming... a hoax?
The Nitrogen piece is new to me, the villain of global cooling mid-Seventies was still CO2. The argument runs that the understanding of the science has improved since the mid-Seventies.

Re: Global Warming... a hoax?
Here's a link to the famous 1975 Newsweek article.

Sceptic though I am, in fairness I don't think it informs the argument one way or the other, but it is amusing to see the assertions of unanimity and the predictions of doom. Imagine what would have happened if we'd initiated plans to warm up the oceans on the basis of this pack of climate changers and the current crop of climate changers were right (or vice versa).

You wonder why there is scepticism?

If you've followed this thread, you'll know that I don't wonder why there's scepticism in the slightest. You might want to re-register your fire. :D

Nothing personal mate. I'm of an age where I can remember previous climate scares - most people can't.
