      Or maybe it won't. You have no guarantee of that.

      The problem is that the price of natural resources fluctuates according to extraction and not total volume. For example if we increase logging in all national forests the price of wood will go down because the supply will increase. The supply is not increasing because there are more trees in the world it's increasing because they are being cut faster.

      In our current scenario we will see the rate of extraction continue at current levels until there is no more and then the market will crash. In other words rationing will not be made in a sane and gradual manner it will come abruptly when we run out.

      Finally the atmosphere may go out of whack way before we run out of any fuel. I don't think that it will happen gradually either.

      1 Watt = 0.00134102209 horsepower

Germany has ecological laws that actually created new jobs and they have already almost reached their Kyoto's objectives. When you develop a new sector, you create new jobs.

      2. If Dinosaurs ruled a tropical paradise 65 million years ago, wouldn't the current trend of Global Warming just be the Earth returning to a Tropical state?

      In short - no. During the Mesozoic both poles were covered by ocean, water could move freely through the oceans, heat was effectively distributed round the globe. Overall temperatures were higher. Since then, Antarctica has slipped over the South Pole and the North Pole is now almost entirely enclosed by land. Oceanic circulation is much more dynamic with cold water forming at the poles and descending to the floor of the oceans - which are only just about freezing point. The warming of these cold waters in the tropics is what holds the temperature way below Mesozoic levels.

And so on. So actually, no, it would be amazing if we WEREN'T screwing up the atmosphere.

      What about bovine methane?

      Methane was estimated to produce about 20% of global warming in the 1990s. Its sources are many - melting permafrost, natural gas leaks, swamps are some of the natural ones. However we contribute to it by things such as rice paddies and those huge herds of cattle which just aren't natural.

      What about a single volcanic eruption spewing more CFC's then we've ever thought about using?

      Errr volcanoes don't spew CFCs. They release carbon dioxide which is a global warming agent, but they also pour out ash, sulphuric acid and hydrogen chloride which serve to depress temperatures.

Most models show that some parts of the planet will get colder (such as northern Europe if the Gulf Stream is curtailed due to ocean salinity). Also, the energy in the atmosphere will increase, causing more violent storms. Witness the hurricane that hit Brazil earlier this year, where those kind of storms have never been before.

We can only infer from historical patterns and climate modeling, which the critics (and vested interests) attack and attack and attack while continuing to buy those SUVs and live in places with incredible energy requirements just to stay comfortable (e.g. Phoenix, Las Vegas). Remeber also that there are two kinds of skeptics, those who are open to new information and willing to be convinced, and those who will never be convinced (for many reasons) and will just nitpick arguments to death.

It's the leading scientific theory of how the climate currently behaves. Surely the least arrogant and egotistical way of looking at things is to build a model based or our best understanding of how the climate works, and see the effect of adding CO2? (answer: global warming) Maybe the models are wrong - but I'd put my faith in them over 'elementary school biology' (or do you have the calculations to back up your claim).

Unless you have plans to increas the planet's green cover, this will have little effect. Of course, increased desertification - a probable result of warming - would have the opposite effect. They're also aware that warming threatens to release masses of greenhouse gasses trapped under permafrost in Siberia, which would accelerate the effect. They're also aware that the earth went through a little ice-age recently. It's not disputed that the earth is going through a naturally warming phase. But the rate of warming is much faster than predicted because of that alone - and fits in well with predictions based on CO2 emissions.

      The fact is that recent climate models, based on our best understanding of the science, do a pretty good job of explaining the earth's climate over the past century, and they indicate that CO2 plays a major role in recent warming, and that without a reduction in CO2 levels, warming will increase.

The global increase in average temperature does not even out accross the globe as the rise of sealevel due to melting of glacial ice.

      Fact is that climate is complex, in some regions temperature will rise more than others. In some regions temperatures may even fall.

      It is the differences in air and water temperature and air pressure - and the rotation of the earth - that keeps the climate systems running.

      Changing these differences means that the climate systems may run faster or slower or in another direction locally.

      This again means that some regions may get more rain and others less. Regions where it will rain more may due to the local geography suffer more floddings, others will become more fertile.

      Changes in temperature can have many and various effects. Increased temperature in the arctic sea may slow down the hot water current from the carribian (golf stream), and eventually stop it. But the reason that northern Europe remains ice free is just because of that current. So stopping it may then trigger a new ice age.

      Another, less rain may form deserts or increase the groth of existing desserts in the affected area. Increasing the dessert area will increase the albedo and reduce temperature.

      More rain is normally associated with more clouds, clouds also increase the albedo, but clouds also functions as an insulating carpet. So which effect is stronger is difficult to say.

      Melting ice means that less areas are covered by ice, this decreases the albedo. Hence the temperature will increase.

      All these are examples of singled out events that has some effect on the system as a whole, all these positive and negative feedback processes are being compared against each other in a complex model.

      What you are doing is taking one example, refer to some ocasion 200 years ago and say "See? There's no global warming causing flodding." This is so overly simplified.

      Possibly, your area will experience less floddings, while whole countries dissappear into the sea due to increased sealevel.
