Came across this interesting article about global warming. Another reason why we should not rush head-long into any solution that might fix global warming. In the end, we need to weigh the costs of doing something against the costs of doing nothing except mitigating the effects of global warming when or if (a very big if) they happen.
There are some, however that would take a more extreme approach such as building huge sunshades to lower the amount of energy reaching the earth or purposefully polluting our planet with aerosols to block sunlight. Now they do say "as a last resort". This, of course makes it all sound really dire. Reality is that even the worst predictions don't even come close to warranting these sorts of "remedies" but it all makes it sound very exciting.
