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.

A study by an international team of researchers, led by Drew Shindell of NASA’s Goddard Institute for Space Studies (GISS) in New York City, has identified 14 measures targeting methane and black carbon (BC) emissions that could reduce projected global mean warming ~0.5°C Source: Shindell et al.

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.

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.

Key developments documented since the IPCC Fourth Assessment Report include: Earth Systems. Global emissions were growing by 1.1% The developing and least-developed economies, 80% of the world’s population, accounted for 73% of the global growth of emissions in 2004. each year from 1990-1999 and this accelerated to 3.5%

Geoengineering is defined as the deliberate large-scale intervention in the Earth’s climate system in order to moderate global warming. However, there are some serious questions over adverse effects, particularly depletion of stratospheric ozone. Unless emissions of carbon dioxide can be greatly reduced—i.e.,
