The planet is tough, our species is tougher we tend to shine out of social and other pressures so why does everyone assume GW would be bad. It could cause our species to achieve new levels of its greatness in the long term. We should be optimistic, adapt as we as a species does thorugh our power of invention and frankly survival of the fittest. But in the long run why be so afraid and make snap and rash policies that could be more destructive to our economy ,perhaps, when there are other areas we should also focus on. Technologies and policies that regardless of GW would make sense to do anyway and are economically viable.
