From the University of California – Santa BarbaraThese are views of vegetation in summer and winter of suburban Minneapolis landscapes from the 500 foot tall KUOM radio tower where measurements for the study were made. In what might be the first study to report continuous measurements of net CO2 exchange of urban vegetation and soils over a full year or more, scientists from UC Santa Barbara and the University of Minnesota conclude that not only is vegetation important in the uptake of the greenhouse gas, but also that different types of vegetation play different roles. Their findings will be published...

The economist Thorstein Veblen once quipped that "invention is the mother of necessity." That was before the age of air-conditioning, but no technology better illustrates Veblen's point. Having developed efficient cooling, we've designed homes, businesses and transportation systems that are completely dependent on it, while the resulting greenhouse emissions create the need for even more air-conditioning. (snip) We must break this feedback loop, but what does one say to someone living in one of the tropical nations where much of the increase in cooling demand is expected? Surely not that Americans are addicted to air-conditioning and can’t give it up,...

As I say, the above demographic audit has become something of an annual tradition in this space. But here's something new that took hold in the year 2007: A radical antihumanism, long present just below the surface, bobbed up and became explicit and respectable. In Britain, the Optimum Population Trust said that "the biggest cause of climate change is climate changers – in other words, human beings," and professor John Guillebaud called on Britons to voluntarily reduce the number of children they have. "Every person who is born," says Toni Vernelli, "produces more rubbish, more pollution, more greenhouse gases and...
