Environmentalists need to fundamentally change their climate change strategy

Pro-fossil fuel forces are pursuing an effective strategy that engages the attention of climate action advocates and obscures the vigorous expansion of fossil fuel supply now underway.

Aluminum smelting defining Iceland elections You no doubt know that Iceland’s elections are coming up on May 12. But here’s something you may not know: the country’s aluminum-smelting boom has become a key issue in the race. With three smelters up and running and three more planned, fans and foes alike are fired up. A […]

Is climate change the most important global problem?

Is climate change the most important global problem we face?

This seems on its face a good question. Economists like Bjorn Lomborg take this reductionist recipe, spice it with an unshakable confidence in future growth, and conclude that climate should be low on our list of priorities.

Lomborg's arguments follow from his assumptions. If his conclusions are wrong as they appear, perhaps the logic is wrong, or the data, or the underlying premises. All of these are good places for skeptical inquiry, and may be fruitful, but there is yet another place to look. I suggest that Lomborg asks the wrong question.

Here’s what we have to accomplish

((brightlines_include))

The supply-side solution developed in the Bright Lines exercise, drawing on Bill Hare's Greenpeace International paper "Climate Protection: The Carbon Logic" (PDF), won little support from first readers. It is included in this proposal as a concept to be explored because no other solution could be determined to meet the dictates of the climate timeframe -- and the strong responses it provokes are evidence of its strong narrative value.

A supply-side response -- imposing a cap on extractions in 2015 with 10 percent reductions at 5 year intervals until emissions are stabilized at pre-industrial levels, as shown in the accompanying chart, for example -- is the ideal climate policy. A cap and phase-down would set clear market parameters for fossil fuels phase-out and establish future economies of scale for renewables and efficiencies, encouraging early investment and driving innovation. Capping extractions would, in effect, move forward the global response to exhaustion of oil and gas reserves, a great challenge even if climate change were not a problem.

Megadroughts projected for southwest: bears

To be "environmental," in simplest terms, is to be aware of the existence of "our fellow mortals," as John Muir liked to put it. In the Southwest, where a new study for Science -- based on the results of nineteen climate model runs -- projects "megadroughts" that will be at least as devastating as the Dust Bowl, some of these mortals, such as black bears and oak trees, have already noticed changes in the climate and begun to change their behavior.

A bullet train, that is

According to this article, Brazil's transport ministry is considering whether to tender bids for a high-speed train linking São Paulo and Rio de Janeiro. Once (OK, if) the bullet train goes into operation, travel time would be just under an hour and a half, compared with the five hours it currently takes to drive between the two cities.

And 92 Percent Think Heather Mills Is a Real Trouper

New poll declares environmental movement still around Just in time for Earth Day, a USA Today/Gallup poll has hit the scene to tell Americans how they feel about the environment. To wit: 60 percent of us believe that global warming is happening now, and even more of us think it will, uh, continue to happen. […]

… before nature does it for us

Following a recent study forecasting permanent drought in the southwest U.S. in coming decades comes this news in today's Salt Lake Tribune. It's a proposal being floated to pipe some of the already dwindling Lake Powell reservoir (currently just half full) in a new direction, to three thirsty counties in southern Utah. Living Rivers' End Lake Powell Campaign says that draining Powell would actually add water to the Colorado River system, given the evaporative losses the lake suffers every day, but federal and state agencies are so far blunt to good logic, which is a shame, when restoring natural flows and water tables along the length of the river would benefit both humans and ecosystems. Seems like nature is going to drain the lake for us, so why not get on with it?

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.
