NASA Scientist says, ‘This is the Last Chance’

Top NASA scientist James Hansen told congress on Monday that the earth is passing the point of no return with regards to the amount of greenhouse gasses in the atmosphere.

Without any changes we could expect (within a couple decades) a collapse of the ecosystem, mass extinction among animals, and a dramatic rising in sea levels.

The main culprit? The burning of fossil fuels.

Is he right?

Well, certainly we have seen our fair share of scientist step forward saying we on a dangerous path (no, Al Gore does not count).

Sen. James Inhofe said in a statement “Hanson, Gore and the media have been trumpeting man-made climate doom since the 1980’s. But Americans are not buying it.”
