New global population predictions
published in Science today says that world population stabilisation is unlikely this century, with an 80% probability that world population, now 7.2 billion, will increase to between 9.6 and 12.3 billion in 2100, greatly exceeding previous consensus figures that settled around 9 billion, and is expected to keep growing next century.

For hundreds of years, mariners have dreamed of an Arctic shortcut that would allow them to speed trade between Asia and the West. Two German ships are poised to complete that transit for the first time, aided by the retreat of Arctic ice that scientists have linked to global warming.

has doubled to 1000 ppm. From shore to the horizon, there is but an unending purple color -- a vast, flat, oily purple. No fish break its surface, no birds. We are under a pale green sky, and it has the smell of death and poison.
Paleontologist Peter Ward's new book
links past mass extinctions to global warming and shows
, absent major changes, "Our world is hurtling toward carbon dioxide levels not seen since 60 million years ago, right after a greenhouse extinction."
Maybe it's time for a heresy
: nuclear energy's green, and renewables aren't.
"The model of economic development that we are currently pursuing is unsustainable. Our energy consumption per unit of GDP is seven times that of Japan, six times that of America, and even 2.8 times that of India. China’s labour productivity is less than 10 per cent of the world total, and yet our emissions are over 10 times higher than the global average.

Al Gore trains 1,000 people
from around the world to share the message he presented in "An Inconvenient Truth".
"The goal had been to train 1,000 "presenters" to show slides of melting glaciers and charts of climbing temperatures, but many more have wanted in.
Those selected to gather at the Hilton Nashville Downtown last week included teachers, doctors, a meteorologist, ministers, Wal-Mart employees, actress Cameron Diaz, architects, retirees, veterans and financiers."
The End of Ingenuity
(NYT OpEd by Thomas Homer-Dixon
)"..cheap energy is tightening, and humankind’s enormous output of greenhouse gases is disrupting the earth’s climate. Together, these two constraints could eventually hobble global economic growth and cap the size of the global economy."

Pat Robertson believes in global climate change.
*brain explodes* Far from heat-induced delirium, Pat may simply be following his flock: evangelicals have embraced the issue of global warming
in recent months. Significantly, the environment
are two issues that are gradually opening a scism between the corporatist and religious wings of the Republican Party, one that Democrats can exploit.
the new urban jungle
. . . is a growing movement led by cities like San Francisco
, New York
, and Leiden
to restore active and vibrant natural systems in urban areas. Far from the eden-like depictions of nature of yesteryear, i.e. the garden of earthly delights
(nonetheless, still attracting some dynamic new christian converts
), the movement has morphed into today's backyard and grassroots environmental movement which is more and more a picture of hybridity, compromise, mixed-use, and ultimately, taking nature out of the walled islands of zoos, aquaria, national parks and other thick-walled institutions and offering a different kind of everyday "unmediated"
community experience with the new urban wilderness
Global warming underestimated by up to 78%.
Scientists analyzing historical climate data for Europe have established the existence of a greater-than-anticipated positive feedback mechanism between high temperatures and global carbon dioxide levels. This provides more scientific evidence to support previously-expressed concerns
that as global warming intensifies, a chain-reaction of considerably higher temperatures may occur. This corresponds with a new report released by the Australian government
, claiming that "there is now perceived to be a greater risk that the upper end of the well known IPCC TAR estimate of a 1.4 to 5.8°C temperature rise will be reached or exceeded by 2100."
"Estimates of future warming . . . may have to be raised by about 50 percent."
One Sweet Campaign To Fight Global Warming
officially launched this month with a press conference a few days ago. Every day, human beings put 16 million tons of carbon dioxide into the atmostphere. The campaign is a joint effort between DMB
and Ben & Jerry's
which uses the new, previously discussed ice cream flavor
as its vehicle, and asks you to pledge to lose 2000 pounds of CO2 this year through reasonable modifications to your daily routine. Help make the world a healthier place. [warning: flash/music]
