April Runs Hot And Cold

This month, the National Oceanographic and Atmospheric Administration gives us a quick lesson reminding us that local weather events can be an inaccurate tool for evaluating the validity of global climate models. Ten days ago, NOAA released figures showing that April 2009 was slightly cooler than average in the United States. Today, however, NOAA released data showing that April 2009 was warmer than average around the world. It was, in fact, remarkably hot, the 5th warmest April ever on record. For that matter, things were warmer than average here in New York State.

Last month, state weather did not predict national climate which did not predict global climate. Always remember that, when people are talking about climate change, scale matters. Global warming is global, not a matter of what you see outside the window on some particular day.

    No problem. If it gets real warm and the ice caps melt we can just evolve with gills and things will be a ok. If we dont evolve that means we were not the fittest and we should have died anyways… Nature will then right its ownship just like it has in the past, or it will evolve to be something different.

    What do you mean ‘if’ the ice caps melt? They are melting, and pretty fast at that. Have you seen the latest reports?
    Here’s the April 2009 report for Arctic ice cover.

    The cover for April 2009 is close to the 1979-2000 yearly average. But the report also states that while the ice cover extent is close to average, the ice is a lot thinner than average so summer melting is expected to be greater.

    then you better evolve faster…

    I know you’re just trying to be funny, but I hope you don’t really think that individual organisms can evolve. Species evolve, but individual organisms cannot.
