Oceans — and ocean activism — deserve broader role in climate change discussions
When President Barack Obama visited the shrinking Exit Glacier in September, he pointed to a very obvious sign of our warming planet literally at his feet. Less visible, but perhaps more indelible, signs of changing climate lie in the oceans. A University of Washington researcher argues in the journal Science that people — including world…
