Well... Just like Dischorran says: the likely consequenses are serious enough. Even the consequenses we can already see are seroious enough. In the likely scenario we can atribute some of the major storms, droughts and floods to global warming (which kind of makes sense. If you input energy into a system, that system has the potential to do more stuff, and a chaotic system will have the potential to do more violent stuff). And I think it's very likely that upcoming droughts and floods and storms in the likely scenario will cost a lot of money. I also think it's likely that they will be responsible for a lot of deaths. Please note that I'm not sayng that every wildfire, storm, drought or flood should be attributed to global warming. Just that global warming is a factor when it comes to weather patterns that are harmfull in the scenario that is most likely acording to a majority of scientists.
It is very likely that severe droughts and creation of new desserts will force people to move (that is already happening, as far as I know). It is somewhat likely that these movements will lead to war over desireble teretories, and over the right to exploit rivers, that dry up as you go downstream.
But in conclusion I would be surprised if global warming won't produce a death toll that is three orders of magnitude greater than the death toll from terrorism (or at least two orders of magnitude greater). A death toll greater than that from wars as well.
Stands to reason then that we should spend at least a hundred times more on trying to prevent global warming than what we spend on trying to prevent terrorism. And if war isn't the greatest threat anymore it stands to reason that we should probably spend a bit less figuring out how to defend ourself against each other, and i little more on how to stop the destruction of our planet (moderate though it might be). Acording to wikipedia (and I'm not going to dig any deeper, since it's not all that relevant) the cost of the wars in Iraq, Afghanistan, and Pakistan is at least $3.2-4 trillion. That's a huge investment, and acording to some the wars have done more harm than good. I would be thrilled if we can find the money that one country spends on wars, with doubtful benefits, on trying to save the planet.
I know there are a lot of other problems in the world as well, but if you take a look over millenia (provided our pieces survives that long) the total death toll from global warming, and other environment problems will be truely enormous.
Don't have time to write anything else, or read the essey you link to (which might be interesting). I'm going to be married today, so I'm kind of on the run
I will say this however:
Eating less meat (especially beef) have a large positive effect when it comes to the release of greenhouse gasses. It's easy, it's cheap and it would be a good idea anyway (since we will get more food per area unit).
Making major cities run with metro systems and busses would be a good idea, regardless of global warming. It's simply not all tyhat healthy with a lot of gasoline cars crammed togeather.
If we agree that nuclear power (inluding chernobyl-like accidents every decade) would be less dangerous than global warming caused by power plants run with fosile fuels it would be quite possible to start using a lot more nuclear power. There is quite a lot of uranium in the sea that could potentially be used.
A lot can probably be done politically as well, by pricing things for their true cost (like realising that there is a lot of value tied to the rain forests, for example, and pricing products that are responsible for the destruction of the rain forest acordingly). It's not obvious that regulations have to be bad for the economy in the long run. Maybe it will lead to creativity if you cannot always use the cheapest solution.
Of course one trillon dollar spent on the right research might go a long way when it comes to coming up with better solutions. Like how to store energy cheaply, which would give solar and wind power a better chance of becoming major players.
My point is this: terrorism to me seems like a tiny threat for humanity, and wars seems like a threat that gets way to many resourses thrown at them. A lot of that money could be spent on combating a threat that is way larger: global climate change.
