Northern forests less effective than tropical forests in reducing global warming
06-21-2007 · EurekAlert!Forests in the United States and other northern mid- and upper-latitude regions are playing a smaller role in offsetting global warming than previously thought, according to a study appearing in this week's issue of Science.

- Brazil demonstrating that reducing tropical deforestation is key win-win global warming solution
05-15-2007 · EurekAlert!
Recent studies by Woods Hole Research Center scientists demonstrate that during years of severe drought, tropical rainforest fires can double emissions from tropical forests. Now, an international team of forest and climate researchers has found that halving deforestation rates by mid-century would account for 12 percent of total emissions reductions needed to keep concentrations of heat-trapping gases in the atmosphere at safe levels. This work is profiled in a recent issue of Science.

- Climate policy: It's good to be in the 'RED'
05-10-2007 · EurekAlert!
Tropical deforestation, which releases more than 1.5 billion metric tons of carbon to the atmosphere every year, is a major contributor to global climate change. Recognizing this, a group of forest-rich developing nations have called for a strategy to make forest preservation politically and economically attractive. The result is a two-year initiative, dubbed "Reducing Emissions from Deforestation," launched by the United Nations Framework Convention on Climate Change.

- Carbon sink capacity in northern forests reduced by global warming
01-02-2008 · EurekAlert!
An international study investigating the carbon sink capacity of northern terrestrial ecosystems discovered that the duration of the net carbon uptake period has on average decreased due to warmer autumn temperatures. Many northern terrestrial ecosystems currently lose carbon dioxide in response to autumn warming, offsetting 90 percent of the increased carbon dioxide uptake during spring.

- Scientists close in on missing carbon sink
06-21-2007 · EurekAlert!
Forests in the United States and other northern mid- and upper-latitude regions are playing a smaller role in offsetting global warming than previously thought, according to a study appearing in Science this week. The study sheds light on the so-called missing carbon sink.

- Trees to offset the carbon footprint?
04-09-2007 · EurekAlert!
How effective are new trees in offsetting the carbon footprint? A new study suggests that the location of the new trees is an important factor when considering such carbon offset projects. Planting and preserving forests in the tropics is more likely to slow down global warming.

- Fires in far northern forests to have cooling, not warming, effect
11-16-2006 · EurekAlert!
Droughts and longer summers tied to global warming are causing more fires in the Earth's vast northernmost forests, a phenomenon that will spew a steadily increasing amount of carbon dioxide into the atmosphere.

- Pollution amplifies greenhouse gas warming trends to jeopardize Asian water supplies
08-01-2007 · EurekAlert!
Scientists have concluded that the global warming trend caused by the buildup of greenhouse gases is a major contributor to the melting of Himalayan and other tropical glaciers. Now a new analysis of pollution-filled "brown clouds" over south Asia by researchers at Scripps Institution of Oceanography at UC-San Diego offers hope that the region may be able to arrest some of the alarming retreat of such glaciers by reducing its air pollution.

- Satellite survey links tropical park fires with poverty and corruption
07-09-2007 · EurekAlert!
According to the first global assessment of forest fire control effectiveness in tropical parks, poverty and corruption correlate closely with lack of fire protection in tropical moist forests. A better understanding of the links between corruption, poverty and park management will help conservationists and policy makers create sophisticated strategies to conserve tropical ecosystems.

- Tropical forests -- Earth's air conditioner
04-09-2007 · EurekAlert!
Planting and protecting trees -- which trap and absorb carbon dioxide as they grow -- can help to remove carbon dioxide from the atmosphere. But a new study suggests that, as a way to fight global warming, the effectiveness of this strategy depends heavily on where these trees are planted. In particular, tropical forests are very efficient at keeping the Earth at a happy, healthy temperature.

- Northern bogs may have helped kick-start past global warming
10-12-2006 · EurekAlert!
Methane gas released by peat bogs in the northern-most third of the globe helped fuel the last major round of global warming, which drew the ice age to a close between 11,000 and 12,000 years ago, conclude scientists from UCLA and the Russian Academy of Sciences.
