"It's essentially game over" for the climate.
That's what climate scientist James Hanson calls the proposed Keystone XL pipeline -- which would carry oil out of Canada's vast tar sands oil fields to Texas, where it will be refined, then burned across the globe, dealing a catastrophic blow to our chance of returning earth to a stable climate.
This project requires a presidential permit to start building -- and it is President Obama's decision alone to grant or deny that permit.
I just signed a petition to President Obama asking him to deny the permit for the disastrous Keystone XL pipeline.
This is a fight we can not lose. Please join me in taking action now:
