Although two polar bear subpopulations (Western Hudson Bay and Southern Beaufort Sea) no longer appear to be viable due to reduction in sea ice habitat, polar bears as a species do not appear to be threatened by extinction in the foreseeable future from either a demographic or an ecological perspective. Ecological perspectives that suggest the reductions to survival and recruitment rates for two populations (Western Hudson Bay and Southern Beaufort Sea) have occurred because of a long-term decline in sea ice due to climate warming. These populations occur where summer ice coverage is seasonal (WH) or divergent (SB). |

This paper reviews effects of large use of biofuels that I predicted in a paper published in August 2006 prior to the USA legislating to enforce displacement of crude oil products by biofuels. The review indicates that policies (such as that in the EU), subsidies and legislation (such as that in the USA) to promote use of biofuels should be reconsidered. The use of biofuels is causing significant problems but providing no benefits except to farmers. |

THERE IS no observational evidence of unusual long-term climate changes in Arkansas. No emissions reductions by Arkansas will have any detectable regional or global effect whatsoever on climate change. |

Variations in climate from year to year and decade to decade play a greater role in the Texan climate than any long-term trends. Short-term variability will continue to dominate the climate in future. The Texas climate shows no statically significant long-term trend in mean annual temperature, rainfall, floods, droughts, heatwaves, tornadoes, or hurricanes – still less any trend that could reasonably be attributed to “global warming”. |

Michael Kaufman, a Post staff writer, describes new research results by Eric Rignot and colleagues that “Climatic changes appear to be destabilizing vast ice sheets of western Antarctica that had previously seemed relatively protected from global warming…raising the prospect of faster sea-level rise than current estimates.” |

The press out of Bali today includes coverage of a World Wildlife Fund (WWF) report about the fate of penguin species under climate change. The press reports draw heavily from the press release put out by the WWF to draw attention to their report on penguins, but more importantly, the WWF’s desire for large and immediate carbon dioxide emissions restrictions. |

On October 18, 2007, The Kansas Department of Health and Environment rejected a request to build two new 700-megawatt coal-fired electricity generating power plants, citing concerns over the contribution of the proposed plants’ carbon dioxide emissions to climate change and “the potential harm to our environment and health.” |

West Nile Virus was introduced to the United States through the port of New York City in the summer of 1999. Since its introduction, it has spread rapidly across the country, reaching the West Coast by 2002 and has now been documented in every state as well as most provinces of Canada. This is not a sign that the U.S. and Canada are progressively warming. Rather, it is a sign that the existing environment is naturally primed for the virus. |
