Sachs: Government Push Needed to Spur Environmental, Anti-Poverty Technologies

Jeffrey Sachs, in an article for Project Syndicate (hat tip Mark Thoma), argues that private sector efforts alone won’t yield sufficient progress in achieving needed progress on the environmental and anti-poverty fronts. Part of this, of course, is the classic problem of externalities: carbon emissions are free to the perps, but impose costs on everyone. […]

Have Ethics Come to Wall Street? Firms Impose Standards on Coal Projects

Perhaps my memory is failing me, but the insistence by three major Wall Street firms, that utilities prove that their new coal-fired plants are economically viable, is at a minimum highly unusual (I’d say unprecedented). Normal Wall Street practice is simply “disclose and sell.” Under securities laws, if the issuer presents its financial situation and […]

Shorter Winters Reduce Effectiveness of Forests as Carbon Sinks

It seems the more we learn about greenhouse gas emissions and climate change, the more we discover that warming processes are self-reinforcing. Melting of Arctic ice means that white polar surfaces, which reflected heat back into the atmosphere, are replaced with open ocean, which absorbs heat well and accelerates warming. As atmospheric CO2 levels rise, […]

Martin Wolf on the Implications of a Zero-Sum Future

Martin Wolf, the Financial Times’ highly regarded economics editor, looks at a fundamental and troubling issue in his latest article, “The dangers of living in a zero-sum world economy.” From the Industrial Revolution onward, the world has enjoyed economic growth, producing rising living standards and making possible an extension of democracy (Wolf argues that the […]

"When Coral Reefs Turn Brown"

Peter Mumby has an article today in the Guardian which discusses an underreported consequence of rising CO2 levels, namely, ocean acidification, which wrecks havoc with the the formation of calcium-based structure. Bye bye shrimp, lobster, and coral reefs. An article in the New York Times, “Before It Disappears,” discusses “the tourism of doom,” for people […]

Kenneth Arrow Makes the Climate Change Math Work

It falls to an uber economist like Nobel Prize winner Ken Arrow to look at climate change and make the economic case for prevention work without resorting to smoke and mirrors. This is a non-trivial accomplishment. For those who have not followed this aspect of the debate, one Sir Nicholas Stern prepared the so-called Stern […]

Climate Change Prediction Markets Launched

An article at VoxEU, “Climate change negotiations PLC?” by Ralf Martin gives a nice recap of some prediction markets on climate change just launched at Intrade. I wish he had gone a bit more into the limitations of prediction markets; while they aren’t a panacea, they have their uses. Big caveats: the markets need to […]

Martin Wolf on the Difficulties of Combatting Climate Change Inertia

Climate change is rapidly joining a host of media stories, like Darfur and the deterioration of living standards in Iraq, where the public half-heartedly follows the updates because they believe there’s no underlying news and even if they are bothered, there is nothing they can do. For example, the final, summary report from the Intergovernmental […]

New York Times: What Didn’t Make It Into the Final IPCC Report

The fourth and final installment of the Intergovernmental Panel on Climate Change’s fourth, summary report is to be released later today. As with earlier versions, certain elements have already been passed on to the press, but there seems to be far less anticipatory chatter than with the previous installments. I hope this isn’t a sign […]
