Wind TurbinesWith the Paris climate talks underway, there’s a thought-provoking article in this morning’s Times about the steps needed to achieve the “deep decarbonization” that could avert the worst impacts of global climate change.  One counter-intuitive conclusion really jumped out at me: some of the simple actions that can achieve immediate reductions in greenhouse gas emissions — such as raising the fuel efficiency of cars and relying more on natural gas to generate electricity — may actually impede long-term goals by locking in technologies based on fossil fuels and delaying a necessary shift to lower carbon systems.  There are no quick fixes.
