Climate Climate & Energy

What’s Produced Here Stays Here

Air Force, Nevada go all crazy with the solar energy The largest solar photovoltaic plant in North America is coming soon to an Air Force base near you — if you live in Nevada. Nellis Air Force Base will install 140 acres of solar panels, powering 30 percent of its electricity needs and reducing electric […]

Indirect greenhouse-gas savings

(Part of the No Sweat Solutions series.)

Previously I pointed out that efficiency, doing more with less, is a key to reducing greenhouse gas emissions. (A lot of people on Gristmill are fans of conservation, doing less with less. I have nothing against this, so long as it is a voluntary choice, but I won't be spending a lot of time on it.)

Normally, when people think of efficiency they think of direct savings -- insulating homes, electric cars, and so on. That is: make the same sort of goods we make now, but more cleverly, so they require fewer inputs to operate. And that is an extremely important kind of efficiency.

But Amory Lovins and Wolfgang Feist pointed out long ago that there is another kind of efficiency. Instead of looking at how to provide the same goods, look at what those goods do for us, and see if there is another way to provide the same service. For example, it remains essential to start making steel, cement, and mill timber more efficiently.

It’s time to accept dire climate realities

((brightlines_include))

A review of recent climate science findings finds that Jim Hansen's bright-line standard and timeframe for global action [1.0ºC limit on further increase in global temperature / 475 ppm cap on atmospheric carbon with <10 years for global action] is, if anything, not conservative enough. A rash of recent reports identify major climate forcings wholly unaccounted for in IPCC models -- such as a five-fold increase in methane releases from Siberian peat bogs -- that support the view of rapid, discontinuous climate change predicted by Hansen.

Energy market projections show that current climate policies will barely dent the ramp-up of fossil fuel use and emissions. U.S. Energy Information Administration (DOE) International Energy Outlook 2006 projects energy-related carbon emissions to increase by 57%, from 25,028 million metric tons in 2003 to 43,676 million metric tons in 2030. Emissions reductions attributable to national environmental policies adopted in furtherance of the Kyoto agreement reduce the EIA reference case by just 58 million metric tons (<1%). Energy market sector leader emissions projections are in the same range; Exxon-Mobil projects an increase from 28 billion to 40 billion tons in the next 25 years (43%).

An increase in carbon emissions in the range 43-57% is more than sufficient to push global temperature above the bright line, roughly between 2020-2030. When the level of atmospheric carbon passes 475 ppm on an upward trajectory, we must assume that Hansen's simple and terrible story -- rapid collapse in Greenland and Antarctic ice shelves, resulting in sea level rise too high and too fast for either civilization or most species to adapt -- will be initiated within the lifetime of our children.

Umbra on home heating

Hi Umbra, My fiancée and I bought a house in October. We plan to green the house up as best we can, and one of our first projects will be how we heat the house. Since we didn’t have any money after buying, we had to limp through this winter with an oil-powered steam boiler […]

Rebuttal ad nauseum

I’m not sure there’s much value left in rebutting Dick Lindzen’s schtick every time it pops up. He keeps saying the same stuff, so the rebuttals keep saying the same stuff, and at this point anyone interested in the schtick or the rebuttal has a panoply of sources close at hand. Nonetheless, Newsweek‘s egregious bad […]

Disagree to Agree

U.N. Security Council hosts feisty climate debate Yesterday the U.N. Security Council held its first-ever debate on climate change, and the meat of the debate was — well, whether the debate should be happening at all. With 55 countries speaking, Britain led the pack of those arguing that climate change threatens global security, while China […]

Now This Is Corn-fusing

Study says ethanol fuel could cause more health problems than gasoline Time to trot out Alanis, cuz this is what the kids call “ironic”: a study from Stanford University says widespread use of ethanol in vehicles could have serious health effects. Atmospheric scientist Mark Jacobson ran computer models comparing air quality in 2020 based on […]

Where is it written that there’s an easy out to replace oil?

Another day, another story about cellulosic ethanol pointing out that, like the Star Wars missile system, it's a technology capable of sucking up endless tax dollars without ever producing anything that delivers in the real world.

Oh, It’s Unparalleled All Right

U.S. claims emissions-reduction success, U.N. Security Council debates climate Today, for the first time ever, the U.N. Security Council will take up the topic of climate change and world security. “The security implications of climate changes are bigger than we thought even two or three years ago,” says John Ashton, a climate lobbyist who pushed […]

Bill Bradlee and David Kroodsma, climate-fightin’ bike riders, answer questions

Bill Bradlee and David Kroodsma. What work do you do? How does it relate to the environment? David: Over the past 17 months, I bicycled from California to the southern tip of Argentina to raise awareness of the international consequences of global warming. I gave talks, visited schools, got in the media, and posted information […]
