The parallels between accepting obesity and ignoring global warming

I have recently been thinking about the parallels between climate change and the obesity epidemic facing the United States and other industrialized countries. Both are the result of our society's desire to consume, and there are similarities in how we might respond. Photo: iStockphoto There are basically three ways to respond to obesity, and each has an analog for climate change. First, you can try to reduce caloric intake. Bob Park calls this the thermodynamic diet: take in fewer calories than you expend and you'll lose weight. For the climate change problem, the parallel is reducing carbon-dioxide emissions. The problem with this approach, of course, is that it is hard. No one likes to diet, and many find it impossible to lose and keep off weight this way. Similarly, our society is not going to find it easy to reduce carbon-dioxide emissions. That does not mean, of course, that it can't be done, or that we won't be happy with the results. I've never met someone who's lost a lot of weight that isn't ecstatically happy with the results, and I think there are many benefits for our society that come along with reducing CO2 emissions. Second, you can simply say, "I'm overweight and I'm going to stay overweight. If I have any health problems, I'll let the doctors solve them for me." So if your weight causes hip problems, just have the hip replaced. If your cardiovascular system goes on the fritz, utilize the latest in cardiovascular care to get the problematic arteries unblocked or a pacemaker installed. If the risk of stroke rises, take the appropriate medication to bring the risk down. A recent news report said that obesity is now a lifestyle choice for Americans. In other words, many overweight people have simply given up trying to lose weight by taking in fewer calories, mainly because they just can't do it. They are now relying on the health care system to deal with the impacts of their obesity:

Plug-in hybrids and electric cars: A core climate solution, nationally and globally

I have a new article in Salon, "The car of the future is here," about plug-in hybrids. The two central points of the article are: Plug-in hybrids (and electric cars) are an essential climate strategy, enabling renewable power (even intermittent sources like wind) to become a major low-cost transportation fuel. Practical, affordable plug-in hybrids will be here in a few years -- even if we don't get a technology breakthrough in batteries. (I am even more confident of these conclusions given the amazing joint announcement today by Renault-Nissan, Project Better Place, and Israel -- see below.) If you read the Salon article, you'll know more than billionaire venture capitalist Vinod Khosla, who recently said: Forget plug-ins. They are nice toys. But they will not be material to climate change. The subject deserves a far more serious discussion. Transportation is the toughest sector in which to achieve deep carbon emissions reductions. Of the three major alternative fuels that could plausibly provide a low-carbon substitute for a significant amount of petroleum:

If you build it, they will come

Growing solar industry depends on key tax credit that will expire this year

Advocates talk a lot about how renewable energy is not just good for the environment, but good for the economy as well. And here is some real-world proof: New Mexico, with strong leadership by Gov. Richardson, PRC Commissioners Lujan and Marks, and many others, has done more than most to establish the full suite of policies necessary to build a solar market. And the reward? Schott AG is investing $100 million in a new manufacturing facility outside of Albuquerque. It will initially employ 350 people, which could grow to 1,500. Good stuff, and congrats to New Mexico. But lookie here at what Schott has to say about what it will take to get to the higher end of the projected jobs numbers:

Biomass, part I

Where will biofuels and biomass feedstocks come from?

When it comes to biofuels we have choices. We can do it poorly, using short-run approaches with no potential to scale, poor trajectory, and adverse environmental impact. Or we can do it right, with sustainable, long-term solutions that can meet both our biofuel needs and our environmental needs. We do need strong regulation to ensure against land-use abuses. I have suggested that each cellulosic facility be individually certified with a LEEDS-like "CLAW" rating, and that countries which allow environmentally sensitive lands to be encroached be disqualified from CLAW-rated fuel markets. We think a good fuel has to meet the CLAW requirements: C -- COST below gasoline L -- low to no additional LAND use; benefits for using degraded land to restore biodiversity and organic material A -- AIR quality improvements, i.e. low carbon emissions W -- limited WATER use. Cellulosic ethanol (and cellulosic biofuels at large) can meet these requirements. Environmentally, cellulosic ethanol can reduce emissions on a per-mile driven basis by 75-85% with limited water usage for process and feedstock, as illustrated later. Range, Coskata, and others currently have small-scale pilots projecting 75% less water use than corn ethanol, with energy in/out ratio between 7-10 EROI (though we consider this a less important variable than carbon emissions per mile driven). Sustainable land use The question about biomass production that arises first is about land use: how much will we need? What will it take? Is it scalable? For conservatism, I assume CAFE standards in the U.S. per current law, though I expect by 2030 to have much higher CAFE and fleet standards (hopefully up near 54mpg or a 100% higher that 2007 averages), which will dramatically reduce the need for fuel an hence biomass. Yes, this would include lighter vehicles, more efficient engines, better aerodynamics, low-cost hybrids, and whatever else we can get the consumer to buy that increases mpg.
