[Vision2020] Canada Tar Sands: 8-3-11: Scientists' Letter to Obama Re: Authorization of Keystone XL Pipeline

Scientific Experts to President Obama Regarding Authorization of the
Keystone XL Pipeline<http://www.tarsandsaction.org/scientists-keystone-xl-obama/>

The Honorable Barack Obama
President of the United States
The White House
1600 Pennsylvania Avenue, N.W.
Washington, D.C. 20050

August 3, 2011

President Obama:

We are researchers at work on the science of climate change and allied
fields. We are writing to add our voices to the indigenous leaders,
religious leaders, and environmentalists calling on you to block the
proposed Keystone XL Pipeline from Canada’s tar sands.

The tar sands are a huge pool of carbon, but one that does not make sense to
exploit.  It takes a lot of energy to extract and refine this resource into
useable fuel, and the mining is environmentally destructive.  Adding this on
top of conventional fossil fuels will leave our children and grandchildren a
climate system with consequences that are out of their control.  It makes no
sense to build a pipeline system that would practically guarantee extensive
exploitation of this resource.

When other huge oil fields or coal mines were opened in the past, we knew
much less about the damage that the carbon they contained would do to the
Earth’s climate system and to its oceans. Now that we do know, it’s
imperative that we move quickly to alternate forms of energy—and that we
leave the tar sands in the ground. We hope those so inclined will join
protests scheduled for August and described at
tarsandsaction.org<http://www.tarsandsaction.org/>
.

If the pipeline is to be built, you as president have to declare that it is
“in the national interest.” As scientists, speaking for ourselves and not
for any of our institutions, we can say categorically that it’s not only not
in the national interest, it’s also not in the planet’s best interest.

Sincerely,

James Hansen
