Promises to Keep
In the run-up to the Paris talks, the major economies have all pledged carbon reductions.
With Saudia Arabia’s pledge last week to cut emission, all of the world’s major economies are now on board. In a nutshell, here is what they are promising. Except as noted, the target dates are all 2030. A number of countries have subsidiary promises in terms of percentage of renewable energy or of bigger cuts premised …

Montreal Protocol parties agree to negotiate amendment to limit HFCs
Last week, the parties of the Montreal Protocol took an important step to broaden their treaty’s chemical controls to contribute to limiting climate change. The chemicals at issue are the HFCs, or Hydrofluorocarbons. (Like the other halogenated chemicals relevant to ozone depletion, the acronym tells you the chemical composition of the class of chemicals. The …

A weird patch of warm weather is killing sea lions and poisoning crabs.
There’s a weird area of warm water, which has come to be known as the Blob, sitting offshore of the West Coast. That doesn’t sound too significant, except perhaps in terms of making things more pleasant for swimmers. But actually, it’s causing a whole cascade of impacts on wildlife and humans. As the Chronicle explains: “The …

CONTINUE READINGGoodbye, Keystone, Goodbye
After seven years, the project is history.
The President announced this morning that he would not approve the Keystone pipeline project. This wasn’t a huge surprise at this point of the game. Still, it’s a good time to take stock of the dispute. The fight was largely — but not entirely — symbolic. With falling oil prices, the alternative of rail transport …

We may need to burn more to get less smoke
One of the impacts of California’s difficult fire season has been air pollution. Fires produce smoke. Large wildfires produce a lot of smoke. And large wildfires in the southern Sierra Nevada produce smoke in the southern Central Valley – the part of the United States that already has some of the worst air quality in …

Why don’t EPA’s proposed rules to reduce methane emissions apply to existing oil and gas facilities?
In August, EPA released proposed rules to reduce fugitive methane and VOC emissions from oil and gas operations. While this is a significant action in the fight against climate change, and much needed in light of the shale-driven national drilling renaissance, there is a gaping hole in the methane rules that has environmentalists worried — …

Exploring Potential Challenges to EPA’s New Source Performance Standard: PART II
This post is the second in a mini-series (see first post) exploring likely legal challenges to the New Source Performance Standard (NSPS) for power-plant greenhouse gas emissions under Clean Air Act § 111(b), and how those challenges might affect the Clean Power Plan. In my first post on EPA’s New Source Performance Standard (NSPS) for …

Climate change will require reconsideration of how we manage fire
It has been a brutal fire season here in California. It’s been brutal in part because of a historically bad drought. But unfortunately, the end of the drought (when it comes) will not be the end of our fire problems. Those fire problems are the result of long-term, human-caused trends that will only continue: climate …

Is climate action finally starting to develop momentum?
There was some good news last week for those of us who worry about the future of the planet,. Both inside and outside of Congress, Pope Francis spoke about the need to protect the environment and address climate change. Some conservative Catholics are eager to dismiss this as simply another misguided opinion by a left-learning Pope. But …
