Thanks for the references and your viewpoint.   Both are really helpful.

Hello Rick

Dear Keith,

You are right of course. I should study the whole treaty rather than rely on what I read about it. Also, my thanks to you for untangling my sentence about Republicans.


Um, sorry, wearing my editor's hat in the wrong place, but I was tempted by the idea of using spontaneously combusting Republicans as an energy source.

I may be being a pessimist here but I don't see the world doing much about global warming in time to stop it's effects.


But do you the propose that therefore we shouldn't even try?

Even if the US got on board the agreements don't seem to me to go far enough.


As I said, all concerned freely acknowledge that. "Nobody closely involved with the Kyoto Protocol sees it as a final document, nor as perfect, just as a first step - it enables further steps."

I know, "go read them" OK I will. By your own figures, a 60 - 80 % cut in CO2, there would have to be a massive change in the way we generate our energy.


Yup.

Look at China just since the treaty was negotiated.


Living in a dream.

Look at South East Asia. I think little can be done until an alternative system for producing energy that doesn't pollute and provides the same amount of energy is in place.


We've discussed this so much here, and other people have discussed it so much elsewhere. Have a look at Lovins's "Negawatts", for instance, or at the many studies that show how appropriate energy offers jobs and prosperity along with everything else, not least to local economies.

"... provides the same amount of energy"? Another dream...

What bothers me more than the US failure to sign the treaty is that lack of serious commitment to replacing fossil fuels. The hydrogen economy proposed by Bush is a joke.


Lack of serious commitment on the part of whom? Corporations with a vested interest in fossil fuels and the status quo and the governments they own, mainly, along with those spun or sent to sleep by the PR they pay for. What's said here very often is that merely replacing fossil fuel use is no answer, nor even an option: in the OECD countries at any rate, a rational energy future requires great reductions in energy use (currently mostly waste), great improvements in energy use efficiency, and, most important, decentralisation of supply to the small-scale or farm-scale local-economy level, along with the use of all ready-to-use renewable energy technologies in combination as the local circumstances require. The powers-that-be will just love that, eh? Nonetheless, that's the context within which biofuels make sense, not in any cloud-cuckooland scenario of "providing the same amount of energy", or as the US DoE and many others see it, not the same amount but more according to projections of current growth figures. Dream on!

Look at these energy use figures:
http://journeytoforever.org/biodiesel_404.html#energyuse

"On a per capita basis, the US uses 5.4 times more than its fair share of the world's energy, the EU 2.6 times its share, Germany 2.6 times its share, France 2.8 times its share, Japan 2.7 times its share, Australia 3.8 times its share... The average American uses twice as much energy as the average European or Japanese and 155 times as much as the average Nepalese. In terms of production, Americans produce more per head than Europeans and about the same as Japanese, but they use twice as much energy as the Japanese to do it."

The Japanese tend to think their use of energy is efficient, and I suppose it is by comparison, but all I see here in Japan is waste, waste, waste.

Have a look at these previous messages for a different view:

Re: Biofuels hold key to future of British farming

As to the effect of global; warming I think your comparison with Venus is a bit over the top.


We're discussing what's called the Greenhouse Effect, triggered by high carbon levels in the atmosphere. Venus is a greenhouse planet. If we all sit here twiddling our thumbs much longer Earth could well also be a greenhouse planet - that's what could come of doing nothing, business-as-usual. It's not over the top, it's a rational projection.

For the last few million years the major trends in climate have been controlled by the orbit of the earth around the sun and the precession or "wobble" in the earth's rotation. These cycles control the amount of energy the earth receives from the sun which varies by about 10% (Ice Ages: Solving the Mystery by John Imbrie and Katherine Palmer Imbrie 1979).


Hamaker, for one, has a different theory, more to do with biomass cycles, which is more in keeping with the Gaia theory. Some of Hamaker's conclusions might be another matter, but his work on soil mineralisation and ice ages makes sense and he supports it well. This opens the possibility of forestalling the onset of another ice age by controlling soil mineralisation, which is not an impossibility (easier than controlling termites!). See:

[Biofuel] Global Warming Approaching Point of No Return, Warns Leading Climate Expert

I don't necessarily subscribe to this, nor to anything much, other than that our human-caused carbon emissions are pushing the global climate towards an uncontrollable disaster. I don't think carbon is the only problem - eg, in the interconnected way of things, nasty links are emerging between global warming and damage to the ozone layer. But carbon is the main and most immediate problem.

For the last two million years or so, the period of time that can be tracked by core borings of ice, the climate has been distinguished by long periods of cold, ice ages, with short periods of warming. With respect to the cycles we should be sliding into a new ice age with the global temperature about two degrees colder than it has been over the last ten thousand years since the end of the last ice age. Apparently, human activity has forestalled this. As noted by another contributor to this group, at some point we will run out of fossil fuel to pollute with


We won't ever run out of fossil fuels, not even of oil. It will just get more and more expensive. I also suspect that, without some such mechanism as the Kyoto Protocol, the current increasing levels of supply would last much longer and stay much cheaper than many people believe. To me the issue isn't that the heroin, sorry, the oil will run out as predicted and we'll all have to give it up, it's that using it like we do is not sustainable anyway no matter how much or how little there might be, and that is a much more pressing issue than that of supply.

and at that point it is possible that the global temperature will crash precipitously to the point in the climate cycle we would have been at had human activity not have occurred.


:-) Greg just said removing the carbon we've added will lead to temperature increases. Are you saying we should keep emitting fossil carbon as long as possible to prevent an ice age? Other scenarios see rising atmospheric carbon as the trigger that causes the onset of an ice age. You're prepared to risk turning the planet into a Venus lookalike or perhaps actually causing an ice age on the strength of your convictions about this?

Global warming is expensive no doubt. So is having New York and Chicago buried under a mile thick layer of ice. I suppose the ideal would be to understand the chemistry of the atmosphere to the point where we could avoid both extremes although you can imagine the fights that would go on between nations as to where to set the thermostat.


The ideal is to stop merely jawing about it and get on with doing something about it. The scientific consensus that carbon emissions must be reduced with all speed is massive, the few kept scientists who demur don't even make a percentage and have been thoroughly exposed as frauds (Singer, Soon, Baliunas et al). With the Kyoto Protocol's coming into force, the scope and scale of action possible has taken a huge leap. Good.

Best wishes

Keith
