This Week in Science
A group of preeminent academics put forward a policy proposal on regulating the development of cellulosic biofuels in the pages of Science magazine last week. They point out the urgent need to think about the unintended consequences of alternative fuels in order to achieve outcomes that are substantially better than “business as usual.” They conclude: Legislated environmental performance standards for cellulosic ethanol production could, for example, go far towards promoting sustainable outcomes. Such standards could Read More >
Weather, Not Biofuels Contributes to Food Crisis
Could it be, that weather, not biofuels, are responsible for the increase in corn prices? That is what Tim of Environmental Economics suggests. Citing rains and floods, as being responsible for leaving 4 million acres unplanted (according to the AP), Tim quotes the AP, “That would likely lift corn prices further, forcing consumers to pay higher grocery bills for meat and pork, as livestock producers would be forced to pass on higher animal feed costs Read More >
Tilman clarifies study
Much of the media coverage of the recent Science Magazine studies made it clear that many hadn’t actually read the studies before they reported on them. Some interpreted the studies as condemning corn ethanol production now, not as the worst case scenario of what could happen in the future. University of Minnesota professor David Tilman, an author of one study, clarified it today in an interview with Minnesota Daily: Tilman, who is currently on sabbatical Read More >
The Truth is Out There: But you have to look
Biofuels are great! There. I’ve been wanting to say that. And I say that not just because I work here at BIO, but because the science in the Science papers needs a little examining. There is misinformation all over the blogosphere. For example, Siko, in the German Carzone posting the following comments today, “Two studies shows that replacing fossil fuels with corn-based ethanol would double greenhouse gas emissions over the next three decades. The studies Read More >
Scientists Respond to Carbon Debt Issue
Reaction to the ScienceXpress articles by Searchinger et al. and Tilman et al. has focused on the assumptions the teams of authors used in measuring greenhouse gas emissions from changes in land use. As Michigan State University Professor of Chemical Engineering Bruce Dale points out, Both of these papers are modeling studies and are therefore completely dependent on the validity of the models themselves and also of the basic assumptions and data input to the Read More >
