"As melting ice opens east Greenland to petroleum prospectors and cruises, scientists are rushing to study the noises made by a remote population of toothed whales."

"The new estimate shows there has been a six-fold increase in annual land ice contribution to global sea level rise from the mid-1990s to the early 2010s."

"The find supports theoretical models of snowball glaciation, which suggest that once ice extends down to 30 degrees of latitude, rapid planetwide glaciation follows."
