Sea level rise as a result of climate change and global warming is a regular news headline here in Boston and worldwide. (See the recent UMass Boston report and the Boston waterfront real estate view).
Every national academy of science reporting to a major government and 97 percent of the most frequently published climatologists say our appetite for fossil fuels is driving an unprecedented rate of planetary warming. But the shifting baseline can be hard to see. Or it used to be.
The examples below are a glacier in Alaska and a coral reef off St. Croix in the US Virgin Islands, two of almost 30 such comparisons made to date by North End photographer David Arnold (www.doublexposure.net). While corals suffer several human afflictions, culprits include rising ocean acidification and the increasing number of heat shocks from fossil fuel burning. Arnold says the the first question he asks any political candidate for any office these days is: “Given the magnitude of scientific evidence, how are you going to lead us?”
