NASA-led study identifies unprecedented depletion of stratospheric ozone layer above Arctic

Green Car Congress

OCTOBER 2, 2011

A NASA-led study has documented an unprecedented depletion of Earth’s protective ozone layer above the Arctic last winter and spring caused by an unusually prolonged period of extremely low temperatures in the stratosphere. The same ozone-loss processes occur each winter in the Arctic.

Emissions of one of the chemicals most responsible for the Antarctic ozone hole are on the rise, despite an international treaty that required an end to its production in 2010, a new study by researchers at NOAA and their colleagues shows. —NOAA scientist Stephen Montzka, lead author of the paper.

DECEMBER 4, 2011

An international team of scientists who monitor the rapid changes in the Earth’s northern polar region say that the Arctic is entering a new state, one with warmer air and water temperatures, less summer sea ice and snow cover, and a changed ocean chemistry.

There are two public hearings scheduled for this proposed finding: 18 May at the EPA Potomac Yard Conference Center, Arlington, VA; and 21 May at the Bell Harbor International Conference Center in Seattle, WA. Climate change has the potential to produce increases in ground-level ozone in many regions, according to the report.

A scholarly literature has documented this process in fields as diverse as engineering, risk reduction, management, and urban studies. One example where this strategy has been successfully employed is the Montreal Protocol on Substances That Deplete the Ozone Layer. Such a plan can disarm opposition before it arises.
