[Climate Change: The Next Generation] Despite the buffering effect of landscape heterogeneity, Arctic ecosystems and the trophic relationships that structure them have been severely perturbed. These rapid changes may be a bellwether of changes to come at lower latitudes and have the potential to affect ecosystem services related to natural resources, food production, climate regulation, and cultural integrity.

[Jennifer Marohasy] Jennifer Marohasy » Marine Cloud Whitening: Best Solution to AGW?: For myself, I would much rather that the supporters of the AGW hypothesis looked for contradictory evidence rather than confirmatory evidence, as such endeavours invariably lead to new and greater insights into the true nature of things than any confirmatory evidence ever does, as the history of science will clearly show to any who care to look.

Compared to a composite reference generated from results of all the 3 PCR assays, the stevor gene amplification had a sensitivity of 100% (Kappa = 1;

And high mercury concentrations in our lakes have affected reproduction in common loons and have been shown to impact bald eagles, mallards, and other birds that reside here.

[Evolution] Evolution » Lake Malawi Cores and Human Origins?: On the basis of well dated paleoecological records from Lake Malawi, which reflect both local and regional conditions, we show that this aridity had severe consequences for terrestrial and aquatic ecosystems. During the most arid phase, there was extremely low pollen production and limited charred-particle deposition, indicating insufficient vegetation to maintain substantial fires, and the Lake Malawi watershed experienced cool, semidesert conditions (

[Comments for RealClimate] RealClimate: The Acid Ocean - the Other Problem with CO2 Emission: In addition to its pivotal role in the atmosphere in the regulation of global climate, CO2 and its sister chemical species, HCO3- and CO32- comprise the carbonate buffer system which regulates the pH of seawater. ...

[The Oil Drum - Discussions about Energy and Our Future] The Oil Drum | Clinton's New Energy and Climate Policy: Establishing an "E8" to Speed Global Action to Address Climate Change: Hillary would invite the G8 nations and key developing countries to join the United States in establishing an "E8." This group would be comprised of the world's major carbon-emitting nations, and would hold an annual summit devoted to international ecological and resource issues -- global warming foremost among them. The E8 would not be a substitute for the United Nations effort to forge a global climate agreement, but rather would streamline negotiations among major emitters and would serve as a catalyst for the larger effort.

[The Spectator.co.uk Melanie Phillips Blog] The Spectator: Sea levels are predicted to rise twice as fast as was forecast by the United Nations only two years ago, threatening hundreds of millions of people with catastrophe, scientists said yesterday in a dramatic new warning about climate change. Rapidly melting ice sheets in Greenland and Antarctica are likely to push up sea levels by a metre or more by 2100, swamping coastal cities and obliterating the living space of 600 million people who live in deltas, low-lying areas and small island states....

Such "either you got it or you don't" scenario is common in SF, but completely unrealistic.

[The Oil Drum - Discussions about Energy and Our Future] The Oil Drum: Europe | Climate Change - an alternative approach: Assuming AGW is true, and irreversable, then the buffering effects of the earth may indeed be 100 years or more to recover from our mess. I suspect that other messes we have created will take far far longer (such as replacing all the farm land with normal ecosystems).

As future models are introduced, the next Cobalt, the next HHR, the next G6 (G7?) the next LaCrosse, the next CTS and even the pickups and SUV’s could all be equipped with this technology.

[GlobalResearch.ca] The World Food Crisis in Historical Perspective: Through this device, India was "force-marched into the world market," and between 1875 and 1900, the worst years of Indian famine, grain exports rose from three to ten million tons annually, an amount equivalent to the annual nutrition of twenty-five million people, coinciding with the rough estimate of twelve to twenty-nine million deaths during this period. As Davis remarks, "Londoners were in effect eating India's bread" and quotes an observer, who wrote: "It seems an anomaly, that, with her famines on hand, India is able to supply food for other parts of the world."(14) Hardly an anomaly, such market perversity is commonplace, occurring for example during the Irish potato famine of the 1840s, a century later in the 1943 Bengal famine, and in recent famines, when food has been diverted for commercial purposes.
