That’s three times the amount estimated by the Intergovernmental Panel on ClimateChange (IPCC). Nitrous oxide is a potent greenhouse gas that contributes to climatechange and stratospheric ozone destruction.
A Memorandum of Understanding has already been signed with Chiapas, Mexico, and Acre, Brazil, at the Governor’s Global Climate Summit 3 to establish these offset programs. At its meeting in Sacramento yesterday, the California Air Resources Board (ARB) endorsed the state’s cap-and-trade regulation.

A few studies also include other relevant impact indicators as acidification potential, eutrophication potential, ozone depletion potential and various toxicity potentials. Hypoxia in the Gulf of Mexico is a complex issue that is not fully understood by the scientific community. However very few studies include water use impacts.
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.
The US, Canada, and Mexico have submitted a proposal to strengthen climate protection under the Montreal Protocol— the international treaty that phases out the production of a number of substances responsible for ozone depletion. Climate protection from the Montreal and Kyoto protocols. Durwood Zaelke. 0902568106.
The US Environmental Protection Agency (EPA) has submitted its final Report to Congress on Black Carbon , in response to an October 2009 request from Congress to advance efforts to understand the role of black carbon (BC) in climatechange. Earlier post.). This GHG effect warms the Earth’s surface and the lower atmosphere.
while the US GDP is projected to grow by 40%, according to the fifth National Communication on US climatechange actions submitted by the US Department of State to the United Nations Framework Convention on ClimateChange. The United States released previous Climate Action Reports in 1994, 1997, 2002, and 2006.
While they do not deplete the ozone layer, many are highly potent greenhouse gases. Their use is growing rapidly as replacements for ozone-depleting substances that are being phased out under the Montreal Protocol on Substances that Deplete the Ozone Layer.
HFCs are chemicals are potential substitutes for ozone-depleting and climate-warming CFCs and HCFCs currently being phased out under the Montreal Protocol treaty to protect the ozone layer. The United States, Mexico, and Canada also proposed a similar amendment.
Global benefits from full implementation of measures for reduction of short-lived climate pollutants in 2030 compared to the reference scenario. The climatechange benefit is estimated for a given year (2050) and human health and crop benefits are. for 2030 and beyond. Source: UNEP. Click to enlarge. Earlier post.).
