I do leave my computer on 24/7. However, being I moved to an area that is predominantly powered with clean energy, it's likely my computer use has far less environmental impact than your limited use. Doesn't detract from your overall point, just adds something else to consider.

(Arizona does get kudos for being predominantly nuclear powered, though)

As you can see, gas price does in fact affect driving, and thus emissions. Though, I'm not an intellectually dishonest person, and will gladly emit that cars aren't the major driver of CO2 emissions.
No- that's not accurate. Clean burning doesn't get you past combustion byproducts. In this instance, carbon dioxide, which is still very fatal in concentration. He just didn't stay there long enough
;)
To add to that, clean burning doesn't mean not much CO2, it means not much other nasty pollutants. CO2 is still a very really problem, however.
Localized disasters can be a real problem at times. Ask the okies, and the states that tried to handle their flux during the dust bowl. Could you imagine if climate change rendered mesoamerica uninhabitable? Where do you think those people are going? Hopefully you guys got your wall with machine guns, right?
The economy can adapt to the needs of the environment and our aggregate needs as a people. The climate didn't collapse when tetraethyllead was outlawed, it didn't collapse when CFCs were, it didn't collapse when sulfur emissions were regulated, it didn't collapse when companies were no longer allowed to dump shit in rivers.
