The largest climate rally in U.S. history is expected Sunday in Washington DC with the aim of pressuring President Barack Obama to reject the Keystone XL tar sands pipeline.

Activists are calling Keystone “the line in the sand” regarding dangerous climate change, prompting the Sierra Club to suspend its 120-year ban on civil disobedience. The group’s executive director, Michael Brune, was arrested in front of the White House during a small protest against Keystone on Wednesday.

“The Keystone XL pipeline is part of the carbon infrastructure that will take us to dangerous levels of climate change,” said Simon Donner, a climate scientist at the University of British Columbia.

To permit the pipeline would represent a heartbreaking acquiescence to climate change on the part of President Obama and our national leaders.

“By itself, Keystone won’t have much of an impact on the climate, but it is not happening on its own,” Donner told IPS.

Carbon emissions are increasing elsewhere, and the International Energy Agency recently warned humanity is on a dangerous path to four degrees C of warming before the end of this century. Children born today will experience this. Preventing that dire future is inconsistent with expanding tar sands production, Donner said.

A new study released this week revealed that the volume of Arctic sea ice is declining rapidly. Ice volume has fallen 80 percent since 1980, according to the latest data from European Space Agency satellite, CryoSat-2. Summers with a sea ice-free Arctic are only a few years away, scientists now agree. This will have significant and permanent impacts on weather patterns in the Northern Hemisphere.

“Keystone XL is the key to opening up the expansion of the tar sands industry,” said Jim Murphy, senior counsel with the National Wildlife Federation.

“By rejecting the Keystone XL tar sands pipeline, we can keep this toxic oil in the ground,” Murphy said in a statement.

Re-engineering our societies to prosper on green alternatives is only option

UXBRIDGE, Canada, Jan 4 2013 (IPS)

Around the world, 2012 was the year of extreme weather, when we unequivocally learned that the fossil fuel energy that powers our societies is destroying them. Accepting this reality is the biggest challenge of the brand new year.

Re-engineering our societies and lifestyles to prosper on green alternatives is the penultimate challenge of this decade.There is no more important task for all of us to engage in because climate change affects everything from food to water availability.

A number of scientific analyses have demonstrated we already have the technology to re-engineer our society to thrive on green alternative energy. The newest of these was published Wednesday in the prestigious journal Nature. It plainly states that politics is the real barrier, not technology nor cost. (It is far cheaper to act than not.)

Keeping global warming to less than two degrees C is mainly dependent on “when countries will begin to take serious action to reduce greenhouse gas emissions”, according to the study “Probabilistic cost estimates for climate change mitigation”.

Climate change has already pushed global temperatures up 0.8 degrees C, with significant consequences. No climate scientist thinks two degrees C will be “safe”. Many countries, especially least-developed countries and small island states, want the global target to be less than 1.5C of heating. Even then large portions of the Arctic and Antarctic will continue to melt raising sea levels, albeit at a slower rate.

Delay in making the shift to non-fossil fuel energy sources will be very costly. Waiting until 2020 to curb global emissions will cost twice as much compared with peaking emissions by 2015, the Nature analysis shows.

Serious action to reduce greenhouse gas emissions means 65 percent of current coal power plants will have to be shut down in the next decade or two, a previous Nature study reported by IPS shows.
