  • Global Temperatures, Volcanic Eruptions, and Trees that Didn’t Bark

    Updated: 2012-02-06 14:36:09
    My co-authors and I have just published an article in Nature Geoscience (advance online publication here; associated press release here) which seeks to explain certain enigmatic features of tree-ring reconstructions of Northern Hemisphere (NH) temperatures of the past millennium. Most notable is the virtual absence of cooling in the tree-ring reconstructions during what ice core [...]

  • Earmarks and the Environment

    Updated: 2012-02-06 11:51:18
    According to a bunch of my federal lobbyist friends, earmarks are back.  Good, bad, both?

    This month’s open thread. Current topics are focused on the laughingly bad Daily Mail article by David Rose, the fallout from the Wall Street Journal’s latest regurgitation of why no-one should ever do anything ever. And perhaps someone might want to audit some of David Whitehouse’s arithmetic and reading comprehension… Or anything else. Within reason.
