More Polar Bear Populations in Decline

More Polar Bear Populations in Decline - Dot Earth Blog - NYTimes.com:

"There is rising concern among polar bear biologists that the big recent summertime retreats of sea ice in the Arctic are already harming some populations of these seal-hunting predators. That was one conclusion of the Polar Bear Specialist Group, a network of bear experts who met last week in Copenhagen to review the latest data (and data gaps) on the 19 discrete populations of polar bears around the Arctic."

"The group, part of the International Union for Conservation of Nature, includes biologists in academia and government and at nonprofit conservation organizations. Only one bear population is increasing (in the Canadian high Arctic), while eight are declining in numbers, the scientists said. At its last meeting, in 2005, the group concluded that five populations were in decline. Three populations appear to be stable and seven are too poorly monitored to gauge a trend."

Penance -- Then and Now

Penance -- Then and Now
In the Middle Ages, there was no buying and selling of carbon indulgences. Now it's a booming business. "The worst of the carbon-offset programs resemble the Catholic Church's sale of indulgences back before the Reformation," said Denis Hayes, the president of the Bullitt Foundation, an environmental grant-making group. "Instead of reducing their carbon footprints, people take private jets and stretch limos, and then think they can buy an indulgence to forgive their sins." The New York Times, 4/29/07

What's a Carbon Footprint?

What's a Carbon Footprint?
A carbon footprint is a "measure of the impact human activities have on the environment in terms of the amount of green house gases produced, measured in units of carbon dioxide". It is meant to be useful for individuals and organizations to conceptualize their personal (or organizational) impact in contributing to global warming. A conceptual tool in response to carbon footprints are carbon offsets, or the mitigation of carbon emissions through the development of alternative projects such as solar or wind energy or reforestation. A carbon footprint can be seen as a subset of earlier uses of the concept of ecological footprints
