    Admit it, Ron. The only reason you post these utterly useless temperature trend articles is because it helps fill your weekly article quota. And don't deny that you have no quotas. What are you, the police?

    I think he just likes the monthly hatefest. With a name like Bailey, he probably has that Irish need to be hated well and often.

    He's probably drunk when he writes the articles anyway, amirite?

  • TheZeitgeist||

    Can be way drunk and still cut-and-paste, make a link. Probably has a template for this one, maybe even a bot to scrape data and swap some keywords/dates.

    Hey, we don't need your Wop sneering about drinking, wino.

  • Auric Demonocles||

    If he really wanted the hatefest, he wouldn't have caved to my alt-text demands (Thanks Ron!)

    Northern Hemisphere: +0.11 C (about 0.20 degrees Fahrenheit) above 30-year average for August.

    The polar bears will soon be swimming in their own blood!

    Or, maybe not.

    You really want to cite the Daily Mail for something not having to do with scantily clad young women?

    I still demand a rolling 30-year average.

  • robc||

    Doing Bailey's work for him, looks like +.13 vs previous 30 Augusts instead of +.16.

    The "trend" is still within the normal year-to-year variation, so not a trend.
