The Enduring Effects of Ozone Depletion
2013-02-01 14:18:00| Climate Ark Climate Change & Global Warming Newsfeed
New York Times: One of the most sobering realities of climate change is that even if all greenhouse gas emissions came to an abrupt halt tomorrow, climbing temperatures, rising seas and extreme weather would still be in the global forecast for perhaps hundreds of years because of the carbon dioxide already released into the atmosphere. To get some perspective, the story of the ozone hole over Antarctica illustrates how even a relatively small perturbation in the atmosphere can have wide-reaching and long-lasting...

Ozone hole changes ocean flow

Australian Broadcasting Corporation: CFC legacy The hole in the Antarctic ozone layer has caused changes in the way that waters in the southern oceans mix, an international study shows. A team of scientists led by Professor Darryn Waugh of Johns Hopkins University, has found that waters originating at the surface at sub-tropical latitudes is mixing into the deeper ocean at a much higher rate than it did 20 years ago, and the reverse is true for waters closer to Antarctica. The study shows these changes are part of the oceans'...
Ozone Holes Shifting Winds May Sap Major Carbon Sink

Climate Central: High above Antarctica, the atmosphere is slowly recovering from the decades-long barrage of manmade chemicals that ate a hole in the protective ozone layer. But the legacy of that destruction lingers. Scientists have linked the ozone hole that forms each Antarctic spring high above Earth to changes in the fierce band of westerly winds that swirls around Antarctica. Those winds, closer to the continent's surface, have grown stronger and moved poleward over the past several decades. This NASA...
New tool to aid ozone program

An ozone-reduction program started last year in Baton Rouge has an online component that could help residents and groups statewide with the local, state and federal effort, organizers said.
Scientist: Ozone thinning has changed ocean circulation

[NEWS] Contact: Phil Sneiderman prs@jhu.edu 443-287-9960 Johns Hopkins University 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 glo…
