The Waxman cometh for Alberta Oil Sands

You mut have heard by now that the emperor of the US (I call him that because he thinks he is above the law and rules by fiat) announced a new meeting to tackle climate change issues. David Roberts of Grist broke it down and concluded that it was worse than nothing. It rejects targets, groups China and India with the developed world, which ensures that nothing will ever come out of his “meeting”, kicks everything down the road until after he has abdicated his throne in 2009, and tries to take advantage of climate change to push for free trade deals.

But this article by Dana Milbank of the Washington Post caught my attention for the rather surreal exchange between a CBS reporter and the White House spokesman.

In this instance, you have a long-term, aspirational goal,” Connaughton answered.

Aspirational goal? Like having the body you want without diet or exercise? Or getting rich without working?

“I’m confused,” Axelrod said. “Does that mean there will be targets for greenhouse gas emission reductions, and that everybody will be making binding commitments?”

“The commitment at the international level will be to a long-term, aspirational goal,” the Bush aide repeated.

Axelrod had his answer. “Voluntary,” he concluded.

“Well,” said Connaughton, “I want to be careful about the word ‘voluntary.’ “

Yes, please do be careful, let’s not over promise and under deliver like we always do!

Connaughton may want to be careful, but the plan the White House outlined yesterday listed no concrete targets or dates, no enforcement mechanism and no penalties for noncompliance. It also wouldn’t take effect until four years after Bush leaves office. It was, rather, a call to spend the final 18 months of the Bush presidency forming an aspirational goal.

Umm, we’re not in 1985 any more, aspirational goals have long since been established, stabilization at 450 ppm C anyone?

I love the emperor and his merry band of climate advisers!

BBC NEWS | Science/Nature | Asias brown clouds warm planet

Clouds of pollution over the Indian Ocean appear to cause as much warming as greenhouse gases released by human activity, a study has suggested. US researchers used unmanned aircraft to measure the effects of the “brown clouds” on the surrounding area. Writing in Nature, they said the tiny particles increased the solar heating of the lower atmosphere by about 50%.

The warming could be enough to explain the retreat of glaciers in the Himalayas, the scientists proposed. The clouds contain a mixture of light absorbing aerosols and light scattering aerosols, which cause the atmosphere to warm and the surface of the Earth to cool.

Wow, I’ll have to read the paper later today to confirm, but when I was doing aerosol work in India back in the mid ’90s, the Indian Ocean cloud was unknown. 1995 through 1998, there was an experiment called INDOEX (my thesis advisor in Bombay participated in the later phases) which first observed this brown cloud. At that time, it was assumed that the light scattering (hence “cooling”) effects of this aerosol would dominate the absorbing (or “heating”) effects, and initial model estimates seemed to agree.

Turns out that it has a significant warming effect because the soot particles (dark, therefore heat absorbing) predominate. And, you had to measure it.

For their study, the team of researchers used three unmanned aircraft, fitted with miniaturised instruments that were able to measure aerosol concentrations, soot amounts and the flow of energy from the Sun.

The crafts flew over the polluted region of the Indian Ocean at varying heights between 500m (1,640ft) and 3,000m (9,840ft).

“During 18 flight missions, the three unmanned aerial vehicles were flown with a separation of tens of metres or less and less than 10 seconds (apart), which made it possible to measure the atmospheric solar heating rates directly,” they wrote.

If true, we can reduce the size of this “cloud” by reducing biomass combustion, installing particle controls on power plants, cleaning up other combustion sources, etc, and reduce global warming effects without worrying that this cloud was somehow mitigating temperature rise as previously thought. So, a win-win!

It is nice to get away into the mountains for a while and not think about work, or climate change, but, reality drags you back. This is a great primer on various CO2 mitigation strategies, explaining in plain language, carbon taxes, cap and trade systems and such. It does tilt heavily towards the carbon tax approach, but that’s fine, I like it better than cap and trade anyway!

The proposed fixes for climate change are as numerous as its causes. Most only tinker at the edges of the problem, such as a California bill to phase out energy-inefficient lightbulbs. To produce the cuts in greenhouse gases needed to slow or stop global warming, the world will have to phase out the fossil fuels on which it relies for most of its power supply and transportation — especially the coal-burning power plants that account for about 32% of the annual emissions of carbon dioxide in the U.S. and that generate about half of our electricity. There are three basic methods of doing that, which are the subject of debate and legislation at every level of government.
