The smart thing to do is to wait, do nothing, then ask & then wait again on answers that won't come, at least not soon enough then walk out on a world summit meeting where 129 other nations are trying to figure what to do & then ask for more time & money for research & then fire the government funded researchers that say the doomsday word. Ask a polor bear if something's wrong. All the new waterfont property will be up for grabs, real cheap, the remaining animals, if there'll be any, won't need to compete with us frail humans, either.
