If we could see the world with a particularly illuminating set of spectacles, one of its most prominent features at the moment would be a giant carbon bubble, whose bursting someday will make the housing bubble of 2007 look like a lark. As yet -- as we shall see -- it’s unfortunately largely invisible to us.
In compensation, though, we have some truly beautiful images made possible by new technology. Last month, for instance, NASA updated the most iconic photograph in our civilization’s gallery: “Blue Marble,” originally taken from Apollo 17 in 1972. The spectacular new high-def imageshows a picture of the Americas on January 4th, a good day for snapping photos because there weren’t many clouds.
It was also a good day because of the striking way it could demonstrate to us just how much the planet has changed in 40 years. As Jeff Masters, the web’smost widely read meteorologist,explains, “The U.S. and Canada are virtually snow-free and cloud-free, which is extremely rare for a January day. The lack of snow in the mountains of the Western U.S. is particularly unusual. I doubt one could find a January day this cloud-free with so little snow on the ground throughout the entire satellite record, going back to the early 1960s.”
In fact, it’s likely that the week that photo was taken will prove “the driest first week in recorded U.S. history.” Indeed, it followed on 2011, which showed the greatest weather extremes in our history -- 56% of the country was either in drought or flood, which was no surprise since “climate change science predicts wet areas will tend to get wetter and dry areas will tend to get drier.” Indeed, the nation suffered 14 weather disasters each causing $1 billion or more in damage last year. (The old record was nine.) Masters again: “Watching the weather over the past two years has been like watching a famous baseball hitter on steroids.” More
