Apple Resigns from U.S. Chamber of Commerce Over Climate Change Policy

Michael Santo — Tue, 06 Oct 2009 10:14:39 -0500

Apple has become the latest company, and probably the highest profile, to leave the U.S. Chamber of Commerce over that organization's stance against limiting greenhouse gases to slow the effects of global climate change. Three other companies, Pacific Gas and Electric, PNM Resources and Exelon, also recently pulled out of the Chamber over its climate policy. Additionally, Nike resigned its position on the Chamber’s board, though it has maintained its membership.

In line with the U.S. Department of Energy (DOE) interest in characterizing the biotic factors involved in global carbon cycling, the DOE Joint Genome Institute (JGI) characterizes a diverse array of plants, microorganisms, and the communities in which they reside to inform options for reducing and stabilizing atmospheric greenhouse gases.

A gas used for fumigation has the potential to contribute significantly to future greenhouse warming, but because its production has not yet reached high levels there is still time to nip this potential contributor in the bud, according to an international team of researchers.

Decisive action needed as warming predictions worsen

Greenhouse gases in the atmosphere are rising more rapidly than expected, increasing the danger that without aggressive action to reduce emissions the climate system could cross a critical threshold by the end of the century, warns a leading member of the Nobel Prize-winning Intergovernmental Panel on Climate Change.

Global warming may delay recovery of stratospheric ozone

Increasing greenhouse gases could delay, or even postpone indefinitely the recovery of stratospheric ozone in some regions of the Earth, a new study suggests. This change might take a toll on public health.

HIAPER, one of the nation's most advanced research aircraft, is scheduled to embark on an historic mission spanning the globe from the Arctic to the Antarctic.

Putting green cap on garbage dumps

Landfill sites produce the greenhouse gases, methane and carbon dioxide, as putrescible waste decays. Growing plants and trees on top of a landfill, a process known as 'Phytocapping', could reduce the production and release of these gases, according to Australian scientists writing in a forthcoming issue of International Journal of Environmental Technology and Management.

Carbon dioxide scrubber captures greenhouse gases

University of Calgary climate change scientist David Keith and his team are working to efficiently capture the greenhouse gas carbon dioxide directly from the air, using near-commercial technology.

Massive greenhouse gases may be released as destruction

Leading world scientists convene in Brazil July 21-25 amid growing concern that evaporation and ongoing destruction of world wetlands, which hold a volume of carbon similar to that in the atmosphere today, could cause them to exhale billows of greenhouse gases.

Permafrost threatened by rapid retreat of Arctic sea ice

The rate of climate warming over northern Alaska, Canada, and Russia could more than triple during periods of rapid sea ice loss, according to a new study led by the National Center for Atmospheric Research (NCAR). The findings raise concerns about the thawing of permafrost, or permanently frozen soil, and the potential consequences for sensitive ecosystems, human infrastructure, and the release of additional greenhouse gases.

Technological breakthrough in fight to cut greenhouse gases
