The European Parliament is calling for fast action to reduce non-CO 2 climate forcers including black carbon soot, hydrofluorocarbons (HFCs), methane, and ground-level ozone, which together are responsible for nearly half of climate forcing. Even cutting CO 2 emissions to zero today will not produce cooling for a thousand years.
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.

Among the non-CO 2 pollutants are hydrofluorocarbons (HFCs), methane, tropospheric ozone, and black carbon soot. The next round of UN climate negotiations begins in Cancun today. ” The authors go on to say that reducing the non-CO 2 pollutants can delay additional climate warming by several decades.
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.
The US reached separate agreements with the G-20 and with China to address the rapid growth in the use and release of climate-damaging hydrofluorocarbons (HFCs). Left unabated, HFC emissions could grow to nearly 20% of carbon dioxide emissions by 2050, a serious climate mitigation concern.
while the US GDP is projected to grow by 40%, according to the fifth National Communication on US climate change actions submitted by the US Department of State to the United Nations Framework Convention on Climate Change. The United States released previous Climate Action Reports in 1994, 1997, 2002, and 2006.
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.
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.
That’s three times the amount estimated by the Intergovernmental Panel on Climate Change (IPCC). Nitrous oxide is a potent greenhouse gas that contributes to climate change and stratospheric ozone destruction. This multi-site experiment clearly establishes streams and rivers as important sources of nitrous oxide.
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 climate change. Effects of BC on climate, as compared to GHGs. Earlier post.). Earlier post.). Source: EPA.
Here, RME show advantages for primary energy and GHG, but disadvantages in terms of acidification, eutrophication and ozone depletion. Rapeseed biodiesel as an example of the varied environmental impacts of a particular biofuel. Source: “Assessing Biofuels”. Click to enlarge.
Global benefits from full implementation of measures for reduction of short-lived climate pollutants in 2030 compared to the reference scenario. The climate change 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.).
Haagen-Smit Clean Air Awards are given annually to individuals who have made significant lifetime contributions toward improving air quality and climate change science, technology and policy, furthering the protection of public health. John Wall, Vice President and Chief Technical Officer of diesel engine manufacturer Cummins Inc.,
Those markets include Australia; Brazil; Canada; China; the European Union; India; Japan; Mexico; Russia; South Korea; and the United States. The team then computed the impacts on health, crops and climate. The research, led by the International Council on Clean Transportation and Environmental Health Analytics, LLC.,
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.
