I'm a trained biologist, but not *not* an eco-nut. However the variety of scientific evidence coming out lately, combined with the interesting stuff on global dimming [bbc.co.uk] has got me seriously worried. And I mean seriously.
I'm sure you are right and the Earth's biosphere will probably cope, over the space of a few thousand years. However I have a two year old daughter, and I would really rather prefer her to enjoy the fruits of our society, rather than watching N. American and Europe become a dust-bowl over the next 40 years.

Key recommendations of the Taskforce include:
1. The G8 and other major economies, including from the developing world, form a G8+ Climate Group, to pursue technology agreements and related initiatives that will lead to large emissions reductions.
2. The G8-Plus Climate Group agree to shift their agricultural subsidies from food crops to biofuels, especially those derived from cellulosic materials, while implementing appropriate safeguards to ensure sustainable farming methods are encouraged, culturally and ecologically sensitive land preserved, and biodiversity protected.
3. G8 governments establish national renewable portfolio standards to generate at least 25% of electricity from renewable energy sources by 2025, with higher targets needed for some G8 governments.
4. G8 governments increase their spending on research, development, and demonstration of advanced technologies for energy-efficiency and low- and zero-carbon energy supply by two-fold or more by 2010, at the same time as adopting strategies for the large-scale deployment of existing low- and zero-carbon technologies.
5. All industrialised countries introduce national mandatory cap-and-trade systems for carbon emissions, and construct them to allow for their future integration into a single global market.
6. A global framework be adopted that builds on the United Nations Framework Convention on Climate Change (UNFCCC) and the Kyoto Protocol, and enables all countries to be part of concerted action on climate change at the global level in the post-2012 period, on the basis of equity and common but differentiated responsibilities.
7. A long-term objective be established of preventing global average temperature from rising more than 2 C (3.6 F) above the pre-industrial level, to limit the extent and magnitude of climate-change impacts.
8. Governments remove barriers to and increase investment in renewable energy and energy efficient technologies and practices by taking steps including the phase-out of fossil fuel subsidies and requiring Export Credit Agencies and Multilateral
Development Banks to adopt minimum efficiency or carbon intensity standards for projects they support.
9. Developed countries honour existing commitments to provide greater financial and technical assistance to help vulnerable countries adapt to climate change, including the commitments made at the seventh conference of the parties to the UNFCCC in 2001, and pursue the establishment of an international compensation fund to support disaster mitigation and preparedness.
10. Governments committed to action on climate change raise public awareness of the problem and build public support for climate policies by pledging to provide substantial long-term investment in effective climate communication activities.

Maybe the world has been coming to an end, just slower than your average Hollywoood movie would have you think it will. Climate change really has happened, and you can talk to plenty of old people living in places like Alaska and they will usually tell you that it used to be colder. There is ample evidence for glacier retreat and ice thinning (the letter from e.g U.S. Navy polar research).
Now, some reports have been overly dramatized - and some people retro-actively exaggerate the reports so they can say that its was all hype. In truth, there is always a range of opinion on something as important as climate change, and you can pretty much alway find someone who says something youi find useful, if you look hard enough.
All that notwithstanding, the large majority of the worlds' climate scientists have over the last 15-20 years consistently been saying that we are causing climate change. There is so much evidence that only someone who wanted to believe otherwise would be in serious doubt.
You make an obvious logical fallacy: the fact that something hasn't happened doesn't prove that it won't happen.
No, climate change will happen over the next 20-100 years. It might be "slow" compared to an asteroid impact, but it will nonetheless happen and it will have an impact on our environment. How much it interfers with civilization is still somewhat up for debate...
There is another example of this sort of thing that I find infomative; when I was a kid I learned about the dangers of over-population, and how diseases were a common consequence. As a kid I thought that there would be a large pandemic that would sweep through the teeming masses and kill millions of people. Of course, I was right - it's just that that pandemic happened slower than I expected (AIDS infects and will kill >20% of some poulations in Africa. That's pretty Malthusian if you ask me).
Why has it better getting progressively colder over the past 20 years in places like Russia and China?
It hasn't. In fact, there are many cities in northern Russia that have a new problem: apartment buildings collapse because the permafrost their foundations sit on has melted. That sounds like warming to me.

While both halves of that are technically true, no one sane would assert that the human effects would result in a run away scenario and Earth turning into Venus. Rather the effect of human activity, if any, will be to push the climate into another relatively stable state.
If nothing else, remember that the carbon we are shoveing into the atmosphere all came from the atmosphere to start with, and a lot more is locked up in carbon rich sedimentary rocks such as limestone and chalk. We're just putting back it back. If we weren't in a run-away situation before life started making mass amounts of cacium carbonate, we aren't going to be after we just put back the relatively small amount of carbon locked up in fossil fuels.

There's a few things we can do. All Canadians by now have probably heard of the one-ton challenge [climatechange.gc.ca]- even Rick Mercer's helping promote it.
For a bit more comprehensive fare, you can try David Suzuki's solutions [davidsuzuki.org].
Political pressure helps, but right now market solutions are probably the easiest way to deal with the crisis. If you have the means to install solar panels or can invest in renewables, go for it.
The most cost-effective and elegant solutions are conservation oriented. Compact fluorescent light-bulbs, LCD rather than CRT monitors, etc... Hybrid or other efficient cars are better than conventional, mass transit beats any car, and changing lifestyles and city planning to reduce the trips we need to make is most elegant.
Energy use estimates have been wildly inaccurate in the past as we got more efficient in using it. At the same time, better tech is getting cheaper as more people buy it and it reaches commodity status. Buying compact fluorescent bulbs 10 years ago didn't just save the energy of that bulb, it helped set in motion a market dynamic that has made them 4 to 5 times cheaper today, and more widely available. Same with LCDs... we as techies can be advocates for this and emerging technology- stuff that meets the same or more needs with less energy.

Devestation (in the sense that it's talked about and covered in the news) relates to damage to the stuff people build, or to the people sitting inside that stuff when it falls down. The biggest factor in hurrican damage for the last 100 years has been the increasing number of expensive things that we've stupidly put on the coasts that are periodically hit, and always have been.
Leaving aside the financial insanity of constantly bailing out (with all of our tax dollars!) those people that insist on putting up yet another house right where another large storm will, inevitably, knock it down... the density of human presence on the eastern seaboard is the main reason for the trouble. Further, all of the coverage speaks in terms of dollars worth of damage, as if a dollar-per-resident-today is the same as a dollar-per-resident-in-1970.
The number of hurricanes per year fluctuates in large patterns, and we've been here before, not that "here" (the semi-busy 2004 season) was particularly bad. For Florida, it sucked. But there've been other years where they dodged the bullets, and it was the Carolinas, or even New England (or you folks in Canada). Big picture, here, folks. Bigger than "since I can remember," which includes fuzzy tall tales from when we were in elementary school.

Gas at $2, $5, or even $8 a gallon won't stop people using gas for their cars; they'll just shift to more economical vehicles or modes of transportation.
Gas at $50 a gallon, or gas availability of only 1 or 2 days a month, on the other hand, makes it impractical to use as a staple of 99.9% of the population's lifestyle. That's when a fundamental shift in society's infrastructure must occur.

Fallout levels depend on whether they are ground or air bursts, and weather patterns. Fallout radiation levels decay quickly. Very little land would be uninhabitable for long periods of time. Contamination is relative. People can live and farm on land that is heavily contaminated by modern radiation safety standards without immediate and severe health problems. Human populations are surprisingly resilient when exposed to non-fatal levels of radiation. If you survive the first 60 days after the event, you will probably live a normal life.

Before you run off an put the cart before the horse (that warming causes CO2), know that we have good, sound physical reasons to expect CO2 rises to cause warming, but few reasons to expect the converse.
Besides, wouldn't the sun be a better analogy for the burner as opposed to CO2? Especially seeing as how solar output has gone up?
If you care to take an analogy too far, then adding CO2 to the atmosphere is like putting a lid on the pot. As for your comment about solar output - that is very unclear, and even the ones who published that said it can't explain all of the observed warming. Not to mention that its a result that doesn't have a lot of back-up, whereas CO2 increases, the observed warming, and the effect of CO2 increases on radiative transport are all things that have been studied by hundreds of researchers.
