Hansen Says Tar-Sands Oil Makes Climate Change Unsolvable

By Alex Morales

Exploiting oil and gas trapped in tar sands and shale threatens to make climate change “unsolvable,” said James Hansen, the former NASA scientist who raised concerns about global warming in the 1980s.

Conventional reserves of oil, gas and coal already have more carbon embedded in them than is safe to burn without causing “dangerous” levels of warming beyond a rise of 2 degrees Celsius (3.6 degrees Fahrenheit) since industrialization, Hansen told a U.K. panel of lawmakers today.

“The potential amount of carbon in these unconventional resources is huge,” Hansen told the Environmental Audit Committee. “If we introduce the tar shale and the tar sands as a source and exploit those resources to a significant extent, then the problem becomes unsolvable.”

Hansen’s intervention comes as U.S. and European Union lawmakers debate measures that would affect the market for oil from Canada’s tar sands. U.S. President Barack Obama’s administration is weighing approval of TransCanada Corp. (TRP)’s proposed Keystone XL pipeline to link the tar sands to U.S. refineries on the Gulf Coast. EU nations are divided on a proposal to classify tar-sand oil as more polluting than conventional crude, putting it at a disadvantage against cleaner fuels under existing EU laws.

There's nothing much I can add to Hanson's stark warning. We as a species have reached a decision point about our own fate.

More Tagging tips:

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc). Keep in mind, though, that there are many wonderful and important diaries that don't fit in any of these tags. Don't worry if yours doesn't.
