Polar bears having fewer cubs due to global warming

Kudos to Iranian journalists for reporting on this issue.


tehran times : Polar bears having fewer cubs due to global warming:
2/13/11

"...Polar bears numbers could plummet with climate change, according to a new study that showed females are giving birth to fewer cubs due to the loss of sea ice.

Researchers at the University of Alberta looked at how melting sea ice in the 1990s effected the breeding success of polar bears.

During the spring and summer months the females are hunting seals on the ice to build up energy for the autumn and winter when they will hibernate for up to eight months and give birth.

The study found the early melting of the ice made it more difficult for the bears to hunt seals successfully and build up energy."

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
