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.

The proposed cause or contribute finding concludes that that the combined emissions of CO 2 , CH 4 , N 2 O, and HFCs from new motor vehicles and motor vehicle engines contribute to the atmospheric concentrations of these key greenhouse gases and hence to the threat of climate change. Technical support document for the proposed findings.

The testing program has eight projects underway or pending, exploring engine and vehicle compatibility and emissions issues resulting from the use of higher blends. Some automakers have done internal testing and have found sensitivity to intermediate ethanol blend levels for non-FFV vehicles. Evaporative emissions durability.

government established a Supersonic Transport Advisory Committee, which began discussions with international partners about building a supersonic airliner. The 1964 Oklahoma City tests involved more than 1,000 flights, which sparked more than 15,000 complaints, as documented in a 1971 report prepared by the National Bureau of Standards.

Key developments documented since the IPCC Fourth Assessment Report include: Earth Systems. This is despite the fact that natural variation will partially offset the warming signal from greenhouse gas emissions. Global emissions were growing by 1.1% each year from 1990-1999 and this accelerated to 3.5% per year from 2000-2007.
