Warming Called a National Security Issue  [archive]
by Matt Crenson, Sci-Tech Today, 4/30/2007
Even with all the recent dire prognostications about global warming, it's doubtful that today's children worry about climate change the same way their parents and grandparents did about nuclear annihilation. So is global warming a national security issue? It depends on how you look at it.

Recruiting Plankton to Fight Global Warming  [archive]
by Matt Richtel, The New York Times, 4/30/2007
In an effort to ameliorate the effects of global warming, several groups are working on ventures to grow vast floating fields of plankton intended to absorb carbon dioxide from the atmosphere and carry it to the depths of the ocean. It is an idea, debated by experts for years, that still sounds like science fiction — and some scholars think that is where it belongs.

Potent Methane Is An Overlooked Greenhouse Gas   [archive]
by David Fogarty, Reuters, 4/30/2007
Farm animals produce lots of methane, a potent greenhouse gas that gets far less public attention than carbon dioxide yet is at the heart of efforts to fight climate change.

Another Consequence of Global Warming: Ocean Dead Zones   [archive]
by Roman Bystrianyk, Health Sentinel, 5/2/2007
As the Earth warms, sea levels will rise and the salt content of the oceans will change as will the ability of the oceans to absorb carbon dioxide from the atmosphere. These changes will interact to affect atmospheric circulation, storm track, storm intensity frequency, and the frequency and distribution of droughts.

Oceans' "Twilight Zones" Offer Key to Understanding Climate Change   [archive]
by Rosanne Skirble, Voice of America, 5/3/2007
New research suggests the ocean's role in locking up carbon dioxide is more complex than we knew, and that before CO2 can be safely sequestered, the gas must first find its way to a particular zone in the ocean depths.

Companies and individuals who want to pay others to cut carbon emissions on their behalf are not always getting real cuts in greenhouse gas emissions, as a voluntary, unregulated trade in carbon offsets mushrooms.

Analysis: Carbon Tax or Carbon Market?  [archive]
by Gerard Wynn, Reuters, 5/2/2007
Hitherto, the idea of a market has been widely acceptable while carbon taxes met opposition. But the market's own failings -- including a system which hands windfall profits to Europe's biggest polluters -- may yet swing the pendulum back.

Climate Panel Reaches Consensus on the Need to Reduce Harmful Emissions  [archive]
by Andrew C. Revkin, New York Times, 5/4/2007
The IPCC's 4th assessment report says that the world needs to divert substantially from today’s main energy sources within a few decades to limit centuries of rising temperatures and seas driven by the buildup of heat-trapping emissions in the air.

Sarkozy Calls on U.S. to Lead Battle Against Climate Change  [archive]
from AP, 5/6/2007
Nicolas Sarkozy, in his victory speech as France's president-elect, urged the United States to take the lead against climate change: "A great nation, like the United States, has a duty not to block the battle against global warming but — on the contrary — to take the lead in this battle, because the fate of the whole of humanity is at stake."

Tackling Climate Change: A Bargain  [archive]
from The Economist, 5/4/2007
"About 0.1% of world GDP would do it." In some areas of economic activity, emissions could be cut with no cost to consumers or taxpayers. This article examines possibilities for cutting emissions by sector.
