Peak Oil is the Least of our Worries


Bill McKibben has written another powerful and chilling piece on climate change, this time in Rolling Stone magazine (link). In it he highlights a few very important numbers concerning fossil fuels and climate change. The scariest one is the amount of carbon stored in known reserves of fossil fuels on the planet, 2795 Gigatons. That dwarfs the amount the atmosphere can handle and maintain any reasonable temperature increase due to global warming (which scientists set at about 2 degrees Celcius). Prior to the latest economic bubble bust, the concept of peak oil was getting a lot of coverage due to the concern about increasing demand and prices relative to known oil reserves. Now that frakking has made billions if not trillions of cubic feet of natural gas available for mining, no one much talks about peak oil anymore. Even if frakking hadn't opened up new natural gas reserves, the world has enough coal to keep polluting the skies and running Industrial Age economies for a century or more.

Economists often like to take a value-neutral stance when it comes to such issues as global warming, assuring us that human ingenuity, market forces, and advances in technology will cure what ails us. But what McKibben has made clear is that the no invisible and price-driven hand will be able to avert the global-scale catastrophes that global warming is already causing. With past progressive movements, such as the abolition of slavery, equal rights for women and minorities, and protection of the environment, economists may point to things like changing economic and technological forces that made slavery and suppression of women's full participation as workers and consumers inefficient and uneconomical and fouling of the environment counter-productive and unnecessary. While interesting, it assumes changing economics and technology are necessary (if not sufficient) for societies to take effective action. 

Regardless of what you think of that argument in general, global warming and climate change simply cannot wait for market forces or technological shifts to make the move away from fossil fuel use toward renewable energy production and sustainable economies inevitable or more efficient. Such changes must be spurred by the moral call to action and the political will to do what is right, not what is expedient. That is why people of faith cannot sit on the sidelines on this issue or urge patience and moderation, as southern ministers asked of Martin Luther King, Jr. in the fight for civil rights. The continuing struggle to overcome ingrained predjudice against minorities and women, e.g. unequal pay, home loan discrimination, and voter ID laws, all speak to the need for a strong moral foundation to ensure we uphold the ideals of the nation and the values we hold most dear as people of faith. Bill McKibben's latest essay not only reinforces the importance of global warming and energy use as moral issues but moreover the need for people of faith to speak out and take action to make it a personal, social, and political priority.
