Earth Is Doomed

If you believe "the science", we're past the point of no return:

Barack Obama has only four years to save the world. That is the stark assessment of Nasa scientist and leading climate expert Jim Hansen who last week warned only urgent action by the new president could halt the devastating climate change that now threatens Earth. Crucially, that action will have to be taken within Obama's first administration, he added.

Were they wrong just 8 years ago?   If no, then what's the point of trying to save the earth if we're already doomed?  And if they were wrong, why would you believe them now?  What additional evidence do we have today that would justify their being wrong 8 years ago but right today?

Disaster is always just around the corner--and that's how the alarmists like it, so they can keep people ginned up and on a war footing.
