More great news from the climate

Nature has published another landmark study showing how the complex interplay of human-generated pollution with natural systems worsens climate change. Their news article (subs. req'd) explains:

Rising levels of ozone pollution over the coming century will erode the ability of plants to absorb carbon dioxide from the atmosphere, a new climate-modelling study predicts.

Ozone is already known to be a minor greenhouse gas, but the new calculations highlight another, indirect way in which it is likely to influence global warming by 2100. High levels can poison plants and reduce their ability to photosynthesize, says Stephen Sitch of the UK Met Office's Hadley Centre for Climate Prediction and Research in Exeter.

Note this is actually a new amplifying feedback, since the hotter it gets the more ozone pollution is generated.

Below the fold is the rest of this article -- and for you hardcore science types, I'll end with the abstract of the original journal article.

A conversation with energy guru Amory Lovins

If politicians think in sound bites and intellectuals think in sentences, Amory Lovins thinks in white papers. His speech is studded with pregnant pauses — you can almost hear the whirs and clicks as an enormous mass of statistics, analyses, and aphorisms is trimmed and edited into a manageable length. I’ve talked to experts who […]

Newsweek reports on green jobs

Newsweek on the growth of the green job market: Graduates of the class of 2007 are finding the job market is receptive to those who want to do good by the environment. As public awareness of global warming grows, companies are scrambling to put in place greener practices, to present themselves as more eco-friendly and […]

They just keep coming

There is constant drumbeat of accusations of hypocrisy against Al Gore for using offsets. Although the people who do this sort of thing are aiming for the lizard brain, I suppose it is worth pointing out that it is an obviously bogus accusation.

Look, I'm an offset critic. I think offsets are one of the biggest wrong turns we can make in fighting environmental destruction, especially global warming. Al Gore, on the other hand, is a strong advocate of offsets. He helped get them into the Kyoto treaty. If I were to buy offsets, I would be a hypocrite -- acting against my beliefs. When Al Gore buys offsets he is acting according to his beliefs. Regardless of whether those beliefs are right or wrong, no hypocrisy is involved.

Yeah, coal again

Sighted in a Saudia Arabian zoo

I interrupt my reporting from Iowa to pass on this curio I found on the blog of my old friend Angelo Young, who works in Saudi Arabia and writes bemused, funny missives from the global crude-oil capital. In this one, he reports a strange sight in a Jeddah zoo: “This Lebanese guy handed the monkey […]

Cherries, their cousins, and a clafouti recipe

I went to a friend’s house for breakfast a few days ago, and she placed an enormous colander full of ripe cherries in the center of the table. Gazing at it made me feel like we were experiencing the very quintessence of summer. It was right up there with the feeling of walking barefoot in […]

Let’s go all the way

When David pointed out that plug-in electric hybrids (PHEVs) can reduce carbon emissions in all possible futures, two main arguments were raised in opposition -- practicality, and the possibility that they will provide too low a reduction, while blocking the path to something better.

The way commercial plug-ins look to be implemented within the next five years is that normal hybrids will be built with large batteries and the ability to plug into a socket in your dedicated parking space. They will travel the first twenty miles or so on electricity and then turn on their gasoline engine around the 21st mile or so. Even with our current grid, they will emit less CO2 per mile than when they switch to their gasoline engine.

Like hobbyists, who manually convert existing hybrids, these will have to be more expensive than a normal hybrid, because they have every expense a normal car has plus the extra battery cost. If gasoline prices rise high enough, I suppose they may pay for themselves in fuel savings, but mostly they will sell on the "cool" factor.

However, there is another way to implement plug-ins, one we could begin now with a large enough investment, which produces savings comparable to a full electric car -- and which, if run on wind, or sun, or other ultra-low-carbon electricity sources, could actually provide a 98 percent emissions reduction.
