General Thoughts on AGU

I returned home from the AGU Fall Meeting last night, and after a good night’s sleep I am almost recovered – it’s amazing how tired science can make you!

The whole conference felt sort of surreal. Meeting and conversing with others was definitely the best part. I shook the hand of James Hansen and assured him that he is making a difference. I talked about my research with Gavin Schmidt. I met dozens of people that were previously just names on a screen, from top scientists like Michael Mann and Ben Santer to fellow bloggers like Michael Tobis and John Cook.

I filled most of a journal with notes I took during presentations, and saw literally hundreds of posters. I attended a workshop on climate science communication, run by Susan Joy Hassol and Richard Sommerville, which fundamentally altered my strategies for public outreach. Be sure to check out their new website, and their widely acclaimed Physics Today paper that summarizes most of their work.

Speaking of fabulous communication, take a few minutes to watch this memorial video for Stephen Schneider – it’s by the same folks who turned Bill McKibben’s article into a video:

AGU inspired so many posts that I think I will publish something every day this week. Be sure to check back often!


The Tar Sands

Apologies for the few weeks of silence. Moving cities again, combined with the beginning of a new term, meant hardly any writing time! I should be back into a regular routine now, though. Enjoy.

In the 2008 presidential campaign, Barack Obama seemed serious about climate change action. He promised an 80% reduction in American greenhouse gas emissions by 2050: a target which, if reached, would go a long way in solving global warming. Therefore, when he won the election, citizens concerned about climate change cheered the world over. “We will restore science to its rightful place,” Obama said following his inauguration. “We will harness the sun and the winds and the soil to fuel our cars and run our factories…All this we can do. And all this we will do.”

This cheery picture of a renewable energy economy is about as far away as one can get from the energy source Obama is now considering supporting: tar sands. Concentrated in Western Canada, the tar sands are an unconventional, and very dirty, form of oil. They produce more carbon dioxide emissions per unit of energy than regular petroleum – in fact, if you take transport and refinery into account, they’re slightly worse than coal. If we aggressively develop the tar sands, we will have no hope of stabilizing climate change at a reasonable level.

The problems don’t end there. Extraction and refinement takes over an incredible amount of land that would otherwise serve as vital habitat for wildlife. Additionally, tar sands are loaded with toxic substances such as heavy metals, which are removed during the refinement process. These byproducts inevitably leach into the water system, endangering the health of nearby First Nations communities and the viability of entire ecosystems in the boreal forest.

In my opinion, this is Canada’s most shameful practice. A short-term spike in jobs will lead to centuries of social, environmental, and economic damage. Sadly, many of our politicians think this trade-off is acceptable.

Now, industry is hoping for an American partnership in tar sand development. The proposed Keystone XL Pipeline would run all the way from Alberta to Texas, so tar could be refined in the US. Imagine the habitat destruction and pollution required to construct this pipeline. Imagine the consequences of a leak in the pipe. And imagine how much more of the tar sands will get dug up and burned if there is a demand from the US.

Luckily, this pipeline requires special permission from the president in order to be built. There is no deadlock in Congress to worry about; no concessions to make for the Tea Party. It’s all down to Obama. Will he keep his campaign promises?

How could someone promise to “restore science to its rightful place” while making decisions that every line of science predicts will endanger our future? How could someone make specific goals and targets, then turn around and take actions that guarantee these goals will fail? If the Keystone XL Pipeline is approved, it won’t be by the Obama we knew in 2008., a nonprofit climate change action group, is coordinating a movement pressuring Obama to reject the pipeline. It includes typical lobbying efforts, including a petition signed by over 600 000 people, but is centered on a two week stretch of civil disobedience. Waves of volunteers formed a peaceful sit-in on White House property, and were willing to get arrested to draw attention to the issue. As of the sit-in’s conclusion on September 3rd, a total of 1,252 people had been arrested, including top climate scientist James Hansen, environmental journalist Bill McKibben, and author Naomi Klein.

Others condemned the pipeline at more of a distance. Recently, nine Nobel Peace Prize Laureates, including the Dalai Lama and Desmond Tutu, wrote to Obama, pleading with him to reject the proposal. Youth leaders from the PowerShift conferences threw in their support. Unsurprisingly, Al Gore denounced the pipeline, calling it an “enormous mistake”.

Is civil disobedience the answer? Will it build up the movement, or polarize it? If governments don’t listen to letters, why would they pay attention to protests? But if they don’t listen to this, why should we trust them at all?
