Long Droughts, Rising Seas Predicted Despite Future CO2 Curbs -- Juliet Eilperin  -- Washington Post  -- January 27, 2009

Greenhouse gas levels currently expected by mid-century will produce devastating long-term droughts and a sea-level rise that will persist for 1,000 years regardless of how well the world curbs future emissions of carbon dioxide, an international team of scientists reported yesterday.


9 Ways NASA Can Tackle Climate Change -- William S. Marshall and James Clay Moltz  -- Scientific American  -- January 20, 2009
Geoengineering

NASA could be one of the nation's most potent weapons in battling climate change. The space agency has conducted decades of research into weather, life-support systems and the atmospheres of other planets providing it with unique skills to address this problem.


Did Icebergs Warm the World? -- Phil Berardelli  -- ScienceNOW Daily News  -- November 21, 2008
Geoengineering

New research indicates that freshwater from melting icebergs may have led to the collapse of the North Atlantic Current and caused previous periods of abrupt global warming.


Current Warming Sharpest Climate Change in 5,000 Years -- Agence France Presse  -- November 9, 2008
Geoengineering

Research on Arctic and North Atlantic ecosystems shows the recent warming trend counts as the most dramatic climate change since the onset of human civilization 5,000 years ago.


Geoengineering: How to Cool Earth--At a Price -- Robert Kunzig  -- Scientific American  -- October 20, 2008
Geoengineering

Global warming has become such an overriding emergency that some climate experts are willing to consider schemes for partly shielding the planet from the sun's rays. Critics warn that no such scheme is a magic bullet and emission reduction strategies will still have to go forward.


Driving Mr. Lynx -- Assisted Migration to help Species Survive Climate Change -- Chris Berdik  -- Boston Globe  -- October 12, 2008
Geoengineering

A growing number of ecologists worry that conservation-as-usual won't be able to keep up with the predicted pace of climate change. To some of them, assisted migration, or helping plant and animal species make the move to a more survivable climate,  is a more proactive tool for preserving nature's richness, and possibly the only hope for saving certain species.


If Climate Changes, It May Change Quickly -- William K. Stevens  -- New York Times  -- January 27, 1998
Abrupt Climate Change

In the debate over global warming, there has been a widespread assumption that if humans are changing the earth's climate, the effects will be felt gradually and smoothly, making it easier to adapt to the change. But a growing accumulation of geological evidence is making it ever clearer that in the past, the climate has undergone drastic changes in temperature and rainfall patterns in the space of a human lifetime, in a decade or in even less time.


The Methane Time Bomb -- Steve Connor  -- The Independent  -- September 23, 2008
Geoengineering

Arctic scientists have discovered that massive deposits of sub-sea methane, a gas 20 times more damaging than carbon dioxide, are bubbling to the surface as the Arctic region becomes warmer and its ice retreats.


Abrupt Climate Change Focus Of U.S. National Laboratories -- Science Daily  -- September 18, 2008
Geoengineering

Six U.S. National Laboratories have launched a program to research abrupt climate change which could be caused by methane release from thawing permafrost, the collapse of ice sheets, or other positive feedback mechanisms.


White Roofs, Streets could Curb Global Warming -- Lisa Zyga  -- PhysOrg.com  -- September 17, 2008
Geoengineering

If the 100 largest cities in the world replaced their dark roofs with white shingles and their asphalt-based roads with concrete or other light-colored material, it could offset 44 metric gigatons (billion tons) of greenhouse gases, a study by Lawrence Berkeley National Laboratory and UC Berkeley shows.
