Debating the Economics of Climate Change

A blog with the great title of Greed, Green and Grains (by environmental economist Michael J. Roberts) reported an interesting national bureau of economic research debate on the economics of climate change.  The debaters were Pindyck (MIT) and Weitzman (Harvard).  It seems increasingly clear that the key factors driving economic conclusions are the treatment of …

Plastic Trees Revisited

Thirty-five years ago, Larry Tribe wrote an article called “Ways Not to Think About Plastic Trees,” probing the foundations of environmental law.  The article prompted an equally interesting response from environmental philosoper Mark Sagoff.  The issue was whether we should preserve nature simply for its utility to humans or whether it had other types of …

It Depends on What the Meanings of “Are” Are

Bill Clinton once famously said that the truthfulness of a statement depended on “what the meaning of ‘is’ is.” There’s a similar usage issue in a recent spat over climate data. A  dispute between Roger Pielke and RealClimate seems to turn in part on whether a statement about current climate trends has to be proven …

Habitat loss still the key conservation concern

Some time ago, I noted this essay in Slate by environmental journalist Brendan Borrell, arguing that our current obsession with climate change is inhibiting more important conservation work. A new report from the International Union for the Conservation of Nature provides some support for Borrell’s position. The IUCN periodically updates its Red List of Threatened …

Climate change breaking news: EPA grants California waiver to regulate GHG emissions from cars

The U.S. Environmental Protection Agency has taken an important step toward addressing climate change and improving our nation’s automobile fuel economy, by granting California and at least 14 other states a waiver allowing them to regulate automobile greenhouse gas emissions.  This was not unexpected, given the recent passage of federal legislation with standards similar to …

“Betraying the Planet”

Paul Krugman has a terrific op. ed with that title in the today’s Times.  Here’s the gist: Do you remember the days when Bush administration officials claimed that terrorism posed an “existential threat” to America, a threat in whose face normal rules no longer applied? That was hyperbole — but the existential threat from climate …

Cool Cars For California

Those California environmental regulators: there they go again… This past week, California’s Air Resources Board adopted first-ever regulations requiring auto manufacturers to include sun-reflecting window glass for all cars and light trucks sold within the state. The new rules take effect in 2014. It turns out that conventional vehicle windows waste a lot of energy. …

Clearing Title (and Rain Forest)

On Friday, the day Waxman-Markey passed the U.S. House, another significant legal development took place — one that may also bear on climate change.  President Lula of Brazil signed a bill providing legal title to squatters on Amazon land.  Opponents argue that it will spark speculation in Amazonian property and increase deforestation.

Climate Bill Passes House!

The Waxman-Markey bill narrowly passed the House yesterday.  This is a historic achievement. As Cara reported yesterday, there are some real qualms about whether the bill is strong enough — and particularly about its heavy reliance on offsets.  Environmentalists have never liked offsets, partly because they lessen the technology-forcing effect of emissions controls and partly …

Climate bill up for a vote

Looks like the House leadership is taking its chances on a vote on Waxman-Markey’s climate bill today or tomorrow, despite some uncertainty about the outcome.   And not all environmentalists are hoping for a victory — in addition to worries about biofuel lifecycle emissions that Jonathan discussed earlier, there’s concern over the recent deal Waxman and Markey …
