By Alister Doyle, Environment Correspondent OSLO (Reuters) – Atmospheric levels of the main greenhouse gas are hitting new highs, with no sign yet that the world economic downturn is curbing industrial emissions, a leading scientist said on Thursday. "The rise is in line with the long-term trend," Kim Holmen, research director at the Norwegian Polar […]
by Richard Harris All Things Considered, January 26, 2009 · Climate change is essentially irreversible, according to a sobering new scientific study. As carbon dioxide emissions continue to rise, the world will experience more and more long-term environmental disruption. The damage will persist even when, and if, emissions are brought under control, says study author […]
GENEVA (Reuters) – Gases blamed for global warming reached record levels in the atmosphere last year, the United Nations weather agency said on Tuesday. Concentrations of carbon dioxide (CO2) and nitrous oxide (N2O) touched new highs after more steady rises in 2007, and methane had its largest annual increase in a decade, the World Meteorological […]
The thawing of permafrost in northern latitudes, which greatly increases microbial decomposition of carbon compounds in soil, will dominate other effects of warming in the region and could become a major force promoting the release of carbon dioxide and thus further warming, according to a new assessment in the September 2008 issue of BioScience. The […]
By Andrew Darby, Hobart THE first evidence suggests that a predicted rise of atmospheric carbon dioxide will wreak havoc on krill, the tiny crustacean at the heart of the Antarctic food web. Although public sympathy for the crustacean is undetectable, polar life such as penguins, seals and whales would wither without it. Captive-bred krill at […]
