    This blog has been an excellent science resource that I hope continues another ten years. Ten years! That’s like seventy in blog years. Well, happy birthday and many happy returns.

    A decade may seem a lot , but it’s time to re up– the Climate Wars put the 100 Years War to shame !

    Also worth recalling today:
    * Nature’s long good-luck editorial “Welcome climate bloggers” endorsing RealClimate in December 2004. The thumbnail summary said: “A group of just nine climate scientists is trying to change the media coverage of their discipline. Thanks to an ongoing revolution in electronic news, they might just succeed.”
    * The RC post “The False Objectivity of ‘Balance'” in 2005. Excerpt: “While giving equal coverage to two opposing sides may seem appropriate in political discourse, it is manifestly inappropriate in discussions of science, where objective truths exist.”

    “Minimum number of times RealClimate was hacked: 2”

    The very first server i stood up on open internet was hacked within two weeks. In 1994.

    So a couple over a decade, not so bad. And you guys recovered very smoothly too.
