Pennsylvania’s Backward Energy Policy

PA's policies look more like the upper South than the mid-Atlantic.

Pennsylvania has a fairly pitiful profile in terms of renewable energy. As of 2015, it got about 4% of its power from renewables, and only about half of that from wind and solar. Nearly all of the remainder was from nuclear (37%), coal (30%) and gas (28%). Perhaps not coincidentally, the state was the nation’s third-largest coal producer in 2016 and the second largest natural gas producer, largely due to fracking. Things do seem to be shifting a bit away from coal: by ...

The impacts of the Anthropocene

The Anthropocene will produce profound economic, social, and political effects on human societies

In my prior post, I explained how humans are increasingly altering or influencing natural systems at a planetary level, and not just through climate change.  Now I want to explain a little about the impacts of those changes on human societies, and the implications of those impacts for how we will respond as societies to the Anthropocene. It is increasingly apparent that climate change will have significant negative impacts on human societies around the world.  Those...

The science of the Anthropocene

Human impacts on global natural systems are large and diverse

Climate change is well known now as a major impact of humans on the planet.  But climate change is only one of a wide range of ways in which humans are dramatically changing natural systems at the regional, continental and planetary levels. For instance, greenhouse gas emissions are the driver of anthropogenic climate change.  But those same greenhouse gas emissions are also causing fundamental changes in our oceans – increased levels of carbon dioxide in the atmo...

Law in the Anthropocene Era

Human impacts on our planet will trigger changes in our legal system

As becomes more and more evident every day, climate change is increasingly a dominant and sometimes devastating factor for human society and natural systems on a global scale. Much has been, and will continue to be, written about how we as a society can reduce the future impacts of climate change and adapt to the impacts that have already occurred or are inevitable. But climate change is in many ways the tip of the iceberg.  It is just one of many ways in which human...

Finally, California Gets A Meaningful Housing Bill

SB 827 (Wiener) would be a game-changer to solve the housing and sprawl crisis

California State Senator Scott Wiener just introduced the bill I've probably been waiting for since I started following land use and transit in California over a decade-and-a-half ago. SB 827 would dramatically scale back local government restrictions on housing near major transit stops (see the fact sheet PDF). These restrictions by local governments have prevented new housing from being built in precisely the job- and transit-rich locations where we need housing the...

Where the Wild Things Are

For endangered species, don't think Alaska or Montana. Think Hawaii and California. And Alabama.

When we think about preserving nature in the United States, we tend to think of the country’s great wilderness areas in places like Alaska and the Rockies. We don’t think about Alabama or Puerto Rico, for instance. But in terms of biodiversity protection, this is almost the opposite of the truth. By and large, the places with endangered species aren’t in those big wilderness areas. They’re in less romantic places – notably including the two I’ve just mentione...

The Ninth Circuit Court of Appeals’ Most Important Environmental Law Decisions of 2017

Constitutional Issues, Water Law, Native American Rights Dominate Court's Environmental Docket

Happy New Year! As we move into 2018, let's take a look back at the most significant environmental law decisions issued by the U.S. Court of Appeals for the Ninth Circuit in 2017. Conventional wisdom is that the second most important federal court in the nation (after the U.S. Supreme Court) is the D.C. Circuit Court of Appeals.  I beg to differ: at least with respect to environmental and natural resources law cases, I strongly believe that the Ninth Circuit is th...

What’s Ahead in 2018? The Top Five Things to Watch For.

2018 will be a big year for environmental law, either for good or for bad.

2016 was a huge year in environmental law, with big achievements like the Paris Agreement and huge disappointments like the presidential election.  By contrast, 2017 was pretty predictable: Trump did just what he promised during the campaign.  The year ahead of us will have some big events to watch out for.  Here are my nominations for the top five in terms of environment and energy. WOTUS.  The Trump Administration has geared up to rescind Obama's WOTUS rule. ...

The California Supreme Court’s Most Important Environmental Law Decisions of 2017

CEQA, Climate Change, Cannabis & Regulatory Takings Top the Justices' Environmental Docket

As 2017 comes to a close, let's take a moment to assess the California Supreme Court's most significant environmental law decisions of the year. There are a large number of decided cases to choose from: as has been true over the past decade, in 2017 the California Supreme Court devoted a substantial portion of its civil docket to cases of interest to environmental lawyers, organizations and the regulated community.  With that caveat, here's my list--an admittedly sub...

Ten Environmental Lessons of 2017

We've learned a lot in the past year, some good, a lot bad.

No one can say it's been a boring year.  In many ways, it's been a worse year than we expected, because the Trump Administration has gone all in on its anti-environmental vision.  But there have also been some heartening positive developments.  Here are some of the most important things, good and bad, that we've learned or at least been forcefully reminded of:  Elections matter. A lot.  Yes, everyone knew this, but after eight years, we were lulled into a sense...
