@layman,

Me neither. One thing I like about Archer is that he doesn't preach, he explains. What's going to happen is that the earth's climate will experience a temperature spike that will last a thousand years or so. It's a spike because the oceans will eventually start absorbing the CO2 and things will get back close to normal, but won't really return to baseline for about 100,000 years. Nobody is sure how big the spike will be because so far, we rely on computer models to provide answers. Nobody has yet discovered how to model how the clouds will be. If they're tall and columnar, warming will be greater. Nobody knows a reason humans couldn't survive it, but it would be warmer than it has been since Homo Sapiens evolved, so something unexpected could arise.
If the clouds are flat and broad, that will reflect light back out to space and reduce surface warming.
Fascinatingly, the earth's climate is headed now into what Archer calls a "trigger point" for reglaciation, which means the glaciers could descend again in something like 1-3 thousand years. BUT, every now and then the trigger is missed (it has to do with how circular the earth's orbit is.) It looks like without increased CO2, the climate would come close to missing it.
If we burn all the coal reserves, then most likely we will miss it and the glaciers won't come back for... I don't remember.. 40,000 years? Anyway, that's my short book review. If you're interested in geo-history, it's definitely worth checking out.
Long story short: no matter what you do with your carbon footprint, the earth's climate is going to be a wild ride for a while. Short of the collapse of human civilization, I don't see how we could avoid burning the coal.
