The BBC conducted a large-scale survey of 22,000 people in 21 countries and found widespread support for curtailing lifestyle in to fight global warming. Note that this survey was conducted before the news of the extraordinary Arctic summer ice melt, which could have shifted opinion further in the direction of taking action. Of course, the […]
Read more...A good article from the Associated Press, “World’s Coal Dependency Hits Environment,” doesn’t appear, at least according to Google News, to have been picked up elsewhere, which is a shame. While the title refers to “world’s,” the story is largely about China. We’ve discussed the environmental damage done by coal-fired electrical plants, yet China and […]
Read more...Martin Wolf, the Financial Times’ highly regarded economics editor, has an usually blunt article today, “Biofuels: a tale of special interests and subsidies.” While the main target is the way special interests are turning biofuels into yet another agricultural pork barrel, he makes a number of important observations: biofuels are only marginally cleaner than conventional […]
Read more...Ozone is getting increasing attention as a greenhouse gas, and the findings are not pretty. We reported earlier on research that found that ozone interferes with plant photosynthesis, which both reduces its effectiveness as a carbon sink and reduces plant productivity. A new MIT study (hat tip Mark Thoma) reports that rising ozone levels are […]
Read more...Human activity has led to a considerable loss of species, and more is in the offing. But what is particularly alarming is that the scientists quoted in the Associated Press and on the BBC today see it coming in mere decades. The discovery is that hotter, wetter periods on this planet are associated with a […]
Read more...The journal Proceedings of the National Academy of Sciences has published an article that finds that atmospheric concentrations of greenhouse gases are rising faster than projected. We reported recently on the fact that oceans are becoming less effective as a carbon sink, an idea independently confirmed by Dr. Corinne Le Quere, of the University of […]
Read more...John Quiggin, Australian economist and popular blogger, participated in the Coral Reef Futures Forum since one of his many roles is to look at the economics of the Great Barrier Reef. In addition to shedding light on the progress and consequences of global warming, Quiggin’s post also provides informative comments on what he calls delusionist […]
Read more...A story on BBC today, citing the US National Oceanic and Atmospheric Administration, attributes the record melt in summer Arctic ice to a shift in wind patterns which the researchers believe was caused by global warming. Worryingly, this appears to be a lasting change. From the BBC: The Arctic is being hit by melting ice, […]
Read more...We’ve mentioned before that higher atmospheric CO2 levels make the oceans more acidic. And that in turn is very nasty for shellfish, coral reefs, and the foundation of the ocean food supply, plankton. As this article in Science Daily reports, the consequences may be even more serious than those of global warming: The world’s oceans […]
Read more...Faithful readers, I hope you will bear with me over the next couple of days. I am having weird problems with my mice, and needless to say, the lack of a properly functioning mouse is a big obstacle to efficient computer use. The result will likely be fewer posts and/or fewer links in posts. I […]
Read more...More disheartening news on the global warming front: Arctic walruses have moved from their customary ice sheet habitat to the rocky Alaskan Northwest coast, raising fears that their new foraging grounds won’t provide sufficient food. From the Associated Press viaPnysOrg: Thousands of walrus have appeared on Alaska’s northwest coast in what conservationists are calling a […]
Read more...A MarketWatch story says that there is a surprisingly effective motivation for people to conserve energy: keeping up with the Joneses. Research indicates that setting an example is more effective than one might think. So whether it’s owning a Prius, using florescent bulbs, or eating more plant proteins (fish and meat are higher up the […]
Read more...Today, the BBC and the Telegraph, among others, discussed the proposal of James Lovelock of Oxford and Chris Rapley, former head of the British Antarctic Survey, to reduce CO2 levels by pumping it into the deep ocean. Note that this is a type of carbon sequestration. Lovelock and Rapley believe this action is necessary because […]
Read more...The Financial Times, in “Wal-Mart seeks emissions data,” reports that the Bentonville behemoth is out to make it suppliers greener: Wal-Mart is to ask its suppliers to measure and report their greenhouse gas emissions, in the biggest move to disclose emissions from businesses. Few companies disclose their emissions, making it difficult to judge which are […]
Read more...The BBC, citing a study in Nature, informs us that climate change models have underestimated the risk of flooding. High atmospheric carbon dioxide levels mean plants suck less water out of the soil. Wetter soil means faster soil saturation in heavy rains, hence more serious flooding. From the BBC: Researchers say efforts to calculate flooding […]
