How to Feed the Billions
February 4, 2010 12:19 PM - Andy Soos, ENN

A Malthusian catastrophe was originally foreseen to be a forced return to subsistence level conditions once population growth had outpaced agricultural production. The catastrophe is that in doing so many people will starve. Sometime around 2050, there are going to be nine billion people roaming this planet two billion more than there are today. It's a safe bet that all those folks will want to eat. Still, not everyone's convinced that feeding nine billion people is a totally impossible task. A Malthusian catastrophe has been predicted before to happen and has not yet done so, A new paper published this week in Science written by Britain's chief scientific adviser John Beddington along with others, outlines a way this could actually be done.

CO2 Regulation in US Hits more speedbumps
February 4, 2010 06:11 AM - Charles Abbott, Reuters

With congressional action on climate legislation in doubt, two House committee chairmen have filed a bill to block the government from regulating greenhouse gases under its own power. The lawmakers say Congress, not "unelected bureaucrats," should set environmental policy. Congress has squabbled for months over a comprehensive climate change bill. Some members say the best bet is to encourage renewable energy production.

Cap and Trade? Maybe not now...
February 3, 2010 06:25 AM - Steve Holland, Reuters

President Barack Obama acknowledged on Tuesday that a controversial "cap-and-trade" mechanism to fight climate change could be separated from other aspects of an energy bill before the U.S. Senate. A cap-and-trade system would set limits on greenhouse gas emissions and allow companies to trade permits to pollute. The system, a version of which was approved by the House of Representatives, is controversial, especially among lawmakers who represent states with big coal reserves.

As Climate Talks Stumble, U.N. Process in Question
February 2, 2010 04:57 PM - Anna da Costa, Worldwatch Institute

A key deadline for countries to submit emission reduction goals to the United Nations as part of the recently negotiated Copenhagen Accord passed last Sunday. The U.N. received commitments from 55 nations, but 139 countries remain unsupportive of the political statement, leading the international body to push back the commitment deadline indefinitely. Since the high-level climate change summit in Copenhagen concluded in December, global climate talks have been in a state of confusion. Two parallel tracks are already under way - one that includes the United States and one that omits this significant world emitter. The Copenhagen Accord, some say, threatens to introduce a third procedural track, complicating the already tense deliberations.

Today is World Wetlands Day
February 2, 2010 08:30 AM - Roger Greenway, ENN

It's World Wetland's Day! For more than 25 years, February 2nd has been designated as World Wetlands Day. Wetlands are under-appreciated in many areas. First we have to drain the swamps, is still a common approach to development in many areas. This approach, of course, is actually a bad idea, a very bad idea, since wetlands, besides being important to the species that live there, are important groundwater recharge areas. World Wetlands Day 2010: "Wetlands, Biodiversity and Climate Change" stresses the fact that caring for wetlands is a part of the solution to climate change with the slogan: "Caring for wetlands – an answer to climate change."

Neanderthal and Climate Change
February 1, 2010 04:33 PM - Andy Soos, ENN

The last Neanderthals in Europe died out at least 37,000 years ago – and both climate change and interaction with modern humans could be involved in their demise. The Neanderthal is an extinct member of the Homo genus that is known from Pleistocene specimens found in Europe and parts of western and central Asia. Neanderthals are either classified as a subspecies of humans or as a separate species. How and why they died out is a matter of debate.

New Ozone Standards could contribute to warming
January 31, 2010 09:40 AM - Richard Harris, NPR, Environmental Health News

The Environmental Protection Agency's proposal to tighten the ozone standard for smog will have an unfortunate side effect: Because of a quirk of atmospheric chemistry, those measures will hasten global warming. There's no question that smog is a hazard that deserves attention. Lydia Wegman of the EPA says the new ozone limits would have significant health benefits. Less smog means fewer asthma attacks, fewer kids in the hospital, fewer days of lost school, "and we also believe that we can reduce the risk of early death in people with heart and lung disease," she says. Here's the tough part: The way many states and localities will reduce smog is by cracking down on the chemicals that produce ozone. And those include nitrogen oxides, or NOx.

Save our Planet!
January 29, 2010 01:45 PM - Andy Soos, ENN

Climate change is hard to imagine since it is dealing with small changes over a long period of time. A new NASA Web site can help younger children understand how and why their planet is changing and what they can do to help keep it habitable. This website is called "Climate Kids". It is geared toward students in grades 4 through 6 and has a multimedia rich website with games and humorous illustrations and animations to help break down the important issue of climate change.

Global Warming Slowed by Decline in Atmospheric Water Vapor
January 29, 2010 07:03 AM - Sid Perkins, Science News

A sudden and unexplained drop in the amount of water vapor present high in the atmosphere almost a decade ago has substantially slowed the rate of warming at Earth’s surface in recent years, scientists say. In late 2000 and early 2001, concentrations of water vapor in a narrow slice of the lower stratosphere dropped by 0.5 parts per million, or about 10 percent, and have remained relatively stable since then. Because the decline was noted by several types of instruments, including some on satellites and others lofted on balloons, the sharp decrease is presumed to be real, says Karen Rosenlof, a meteorologist at NOAA’s Earth System Research Laboratory in Boulder, Colo.

Concern About Global Warming Continues to Drop in the U.S
January 28, 2010 06:26 AM - Yale Environment 360

Concern about global warming among U.S. adults has dropped significantly, a new poll says, with fewer than 50 percent of Americans saying they are "somewhat" or "very worried" — a 13 percent decrease from a poll taken in October 2008. The percentage of Americans who believe global warming is occurring fell 14 percent to 57 percent, and the percentage who think global warming is caused primarily by human activities fell 10 percent to 47 percent, according to the poll funded by the Yale Project on Climate Change and the George Mason University Center for Climate Change Communication.
