According to a Johns Hopkins earth scientist, the hole in the Antarctic ozone layer has caused changes in the way that waters in those southern oceans mix – a situation that has the potential to alter the amount of CO2 in the atmosphere and eventually could have an impact on global climate change. In a paper published in today’s issue of the journal Science, Darryn W. Waugh and his team show that subtropical intermediate waters in the southern oceans have become “younger” as the upwelling, circumpolar waters have gotten “older” – changes that are consistent with the fact that surface winds have strengthened as the ozone layer has thinned.

The National Snow and Ice Data Center at the University of Colorado has reported that there is less ice in the Arctic Ocean this summer than at any time since satellite measurements were first taken back in 1979, a finding that underscores the reality of global climate change. Johns Hopkins oceanographer Thomas Haine, who studies how the physics of ocean currents affects global climate, is available to put these findings into perspective.
