What will it take to make 2008 great?

The following guest post is by Rep. Jay Inslee (D-Wash.), originally published on Climate Progress. He is the co-author of Apollo's Fire: Igniting America's Clean Energy Economy.

Now that our New Year's Eve party hats are put away, it's time to look to the next year in the battle against global warming. In the year 2007, some good things did indeed happen on this front. Measures significantly improving car mileage standards and promoting the growth of renewable fuels were signed into law. But if 2007 was a year that could be considered in some ways good, then 2008 needs to be a year that will be great.

Nothing else will do. The cataclysms of one million square miles of ice melting in the Arctic, a several-fold increase in the rate of melting tundra, and the acceleration of melting in Greenland, foretell possible feedback mechanisms that demand a faster and more aggressive clean energy revolution than we even envisioned a year ago. Whatever we thought necessary on New Year's Day 2007 needs to be doubled in 2008.

So what will it take to make '08 great? Three things will do the trick.

Ex-Im to finance more clean energy exports

The appropriations omnibus bill just passed through Congress "recommends that the Export-Import Bank provide 10 percent of its financing capacity to promote the export of clean energy products and services." This was a recommendation by many groups, including the Center for American Progress:

Having supported more than $400 billion dollars of U.S. exports during the past 70 years, the Export-Import Bank is one of the most powerful tools at the U.S. government's disposal for spurring innovation and economic growth.

But in yet another backward-looking strategy typical of this administration:

Cogeneration and ethanol production

I am not the biggest fan of corn ethanol. But I am the biggest fan of cogeneration, also known as combined heat and power, or CHP (well, maybe the second-biggest fan). It is probably the single most overlooked strategy for sharply cutting greenhouse-gas emissions while reducing overall energy costs.

Now a new EPA report finds that running an ethanol plant on natural gas CHP can, with the right design, result in negative net CO2 emissions (click on figure to enlarge).

Important caveat: "Impact of Combined Heat and Power on Energy Use and Carbon Emissions in the Dry Mill Ethanol Process" (PDF) does not examine the energy consumed (or emissions generated) from growing and harvesting the corn or from transporting the corn or ethanol. Still, with CHP, corn ethanol can actually generate significant CO2 reductions compared to gasoline.

If Congress is serious about promoting ethanol in a manner that actually reduces GHGs, they should require all new ethanol plants to cogenerate.

Sea levels may rise five feet by 2100

A recent Nature Geoscience study, "High rates of sea-level rise during the last interglacial period," ($ubs. req'd) finds that sea levels could rise twice what the IPCC had project for 2100. This confirms what many scientists have recently warned (also see here), and it matches the conclusion of a study (PDF) earlier this year in Science.

[As an aside, in one debate with a denier -- can't remember who, they all kind of merge together -- I was challenged: "Name one peer-reviewed study projecting sea-level rise this century beyond the IPCC." Well, now there are two from this year alone!]

For the record, five feet (PDF) of sea level rise would submerge some 22,000 square miles of U.S. land just on the Atlantic and Gulf Coasts (farewell, southern Louisiana and Florida) -- and displace more than 100 million people worldwide. And, of course, sea levels would just keep rising some six inches a decade -- or, more likely, even faster next century than this century.
