An unbiased, factual report on biofuels: How rare is that?

The Worldwatch Institute has produced an interesting summary of what's happening in the world of grain supplies.

They also just published a book called Biofuels for Transport. Along with all of the positive potential for biofuels, I'm sure it also discusses the "potential" problems with "first generation" biofuels.

These are some of the latest buzzwords being used to support industrial agrofuels. The word "potential" suggests that there are not yet any actual problems. The words "first generation" suggest that all of these "potential" problems will fail to materialize thanks to the timely arrival of "second generation" fuels.

The reality, of course, is that these fuels (i.e., industrially grown food monocrops) are already wreaking all kinds of havoc and are likely to remain the only commercially viable biofuels for the foreseeable future (i.e., forever).

High drama leads to compromise at climate conference

After days of bitter fighting and an overtime stretch filled with twists and turns and even tears, world leaders on Saturday came to agreement on a rough roadmap for developing a new global climate treaty by 2009. The European Union had pushed for industrialized countries to commit to cuts in greenhouse-gas emissions of 25 to […]

Why ecology explains growth, and economists don’t

Recently there have been a number of discussions concerning economic growth and global warming. Some have argued that the effort to prevent as much global warming as possible will incur unacceptable costs to the global economy in terms of growth. Others have argued that growth is causing global warming.

I want to argue that neoclassical economics is badly designed to help with this debate. The two main problems, in my opinion, are that economics does not see the economy as being composed of a set of nonsubstitutable "life support" functions, to use Joshua Farley's phrase; and the neoclassical theory of economic growth is inadequate (PDF) for understanding how global warming (and most everything else) will effect growth.

The problem of economic growth looms large in both the DICE model put forward by William Nordhaus, and the Stern Report, led Sir Nicholas Stern, because they both calculate the extent to which global warming and global warming mitigation will effect growth. In 1991, Stern opined that growth theory "has, however, been a popular topic for those involved in formal economic theory only for short periods, notably from the mid 1950s to the late 1960s." There is a good reason for this: neoclassical growth theory doesn't really explain economic growth.

U.N. creating small Adaptation Fund by going carbon neutral

The following essay is a guest post by Kari Manlove, fellows assistant at the Center for American Progress.

-----

The IPCC has warned us that developing nations are poised to bear the most dramatic effects of global warming, and so far we (the world) have done practically nothing to counter or prevent that fact. But the U.N. is trying.

This week in Bali, the U.N. announced that it will go carbon neutral by offsetting the operations of over 20 agencies, including the office of Secretary General Ban Ki-Moon. With the money collected, the U.N. will invest in an Adaptation Fund to help developing countries combat the consequences of climate change in coming decades. At its start, the fund will be worth no more than $50 million, but advocates hope that number will grow as we see increasing need for a fund of its type.

Walruses trampled as a result of climate change — no, seriously

Here’s a climate-change impact you don’t think about every day: trampled walruses. When walruses get tired of swimming, they clamber onto sea ice to rest. As ice is in increasingly short supply above the Arctic Circle, walruses are huddling on shore in extremely high numbers. And as the tusky animals are liable to stampede at […]

James Hansen talks about what to do now that we’ve passed the ‘tipping point’

For the last few years, James Hansen, the man who first warned Congress of global warming in testimony last century, and the man considered NASA's "top scientist" on climate questions, has been giving talks around the country asking can we avoid dangerous climate change (PDF)?

But Hansen has changed his tune: no longer does he ask if we have passed the tipping points of climate change. In a press conference Thursday morning at the American Geophysical Union, he stated that we have passed several tipping points. He said scientists now know that soon the Arctic will be ice-free in the summer, that huge ice sheets will melt, and the climactic zones will shift towards the poles of the earth, among other consequences.

Climate skeptic steps up

We've finally found someone willing to debate me: Tim Ball, a retired professor from the University of Winnipeg. The debate will be online Monday, Dec. 17, at 2 p.m. CST.

You will be able to listen online through BlogTalkRadio's service. In fact, you can even call in during the show (see the BlogTalkRadio web site for details). You can also post questions on SciGuy Eric Berger's website.

I realize that these types of events don't do much to move the climate debate forward. I'm mainly doing this to test my own ability to answer the skeptic's questions and see how I fare in this type of activity.

For those who miss it live, it will be archived in mp3 format.

Bali climate meeting goes overtime, drops specific emissions targets

The two-week United Nations climate conference in Bali, Indonesia, has gone into overtime, lasting past its scheduled end as the U.S., Canada, and Japan duked it out with European countries and developing nations in a battle over emissions targets. As expected, the U.S. team, led by Chief Negotiator “Snarlin'” Harlan Watson, has successfully negotiated against […]

Sights and sounds from an Arctic research vessel

In late November, I began a three-week stay on the CCGS Amundsen, a Canadian Coast Guard ice-breaker and scientific research vessel that is spending 15 months in the Arctic. This expedition will be the first ever to spend the winter moving through sea ice north of the Arctic Circle — and at present, I am […]

Forest Service objects to Va. ‘clean coal’ plant that would be one of state’s biggest polluters

I should have added this to my account of state-level coal backlash: The U.S. Forest Service is warning Virginia environmental officials that pollution from a $1.6 billion coal-fired power plant proposed for Wise County would violate federal clean-air laws. In a letter to the Virginia Department of Environmental Quality, the supervisor of the Pisgah National […]
