    Growing need for space trash collectors

    On April 2, for the fifth time in less than three years, the International Space Station fired its engines to dodge a piece of orbital debris that appeared on a collision path. Other spacecraft also regularly scoot out of the way of rocket and satellite debris. Such evasive action will be needed increasingly frequently, a new study finds.

    Marine microbes prove potent greenhouse gas emitters

    Earth’s oceans emit an estimated 30 percent of the nitrous oxide, or N2O, entering the atmosphere. Yet the source of this potent greenhouse gas has puzzled scientists for years. Bacteria — long the leading candidate — can generate nitrous oxide, but the seas don’t seem to contain enough to account for all of the nitrous oxide that the marine world has been coughing up. Now researchers offer a better candidate.

    AAAS board defends climate scientists

    “AAAS vigorously opposes attacks on researchers that question their personal and professional integrity or threaten their safety based on displeasure with their scientific conclusions.” This declaration was contained in a 400-word denunciation of attacks on climate scientists and the politicization of climate science that was issued June 29 by the organization's board of directors.

    It’s time to put a price on carbon, NRC says

    “It is imprudent to delay actions that at least begin the process of substantially reducing emissions [of greenhouse gases],” according to a May 12 report by the National Research Council. It didn’t get a lot of press play in the past week, perhaps because its 144 pages don’t say anything readers might not have expected this august body to have proclaimed years ago. But that shouldn’t diminish the significance of this report, its authors contend.

    Record ‘Arctic’ ozone minimum expands beyond Arctic

    In mid-March, our online story about the thinning of stratospheric ozone over the Arctic noted that conditions appeared primed for regional ozone losses to post an all-time record. On April 5, World Meteorological Organization Secretary-General Michel Jarraud announced that Arctic ozone had indeed suffered an unprecedented thinning. And these air masses are on the move to mid-latitudes.
