GREENBELT, Md., Dec. 7, 2010 /PRNewswire-USNewswire/ -- A new NASA computer modeling effort has found that additional growth of plants and trees in a world with doubled atmospheric carbon dioxide levels would create a new negative feedback - a cooling effect - in the Earth's climate system that could work to reduce future global warming.

The challenge we face is enormous. Since 1750, atmospheric carbon dioxide levels are up 38 percent, from 280 to 385 parts carbon dioxide for every million particles in the atmosphere. The wind farm will produce enough energy to power a city of 500,000 people, while reducing carbon dioxide emissions by 600,000 metric tons each year.
GEOENGINEERING AND THE AUDACIOUS QUEST TO FIX EARTH'S CLIMATE BY JEFF GOODELL Houghton Mifflin Harcourt, 272 pages, $26.00 During the 1950s, the atomic scientist Edward Teller was eager to prove that nuclear bombs could be used in construction as earthmovers, and in 1958 he won the approval of the U.S. Atomic Energy Commission for Project Chariot, a proposal to explode several multi-megaton hydrogen bombs near Point Hope, Alaska, just above the Arctic Circle. [...] the locals couldn't be sold on a harbor that would be iced in for nine months of the year. According to the best available modeling, blocking just 2 percent of the sun's radiation would counteract a doubling of atmospheric carbon dioxide.
The fight against the delusion of dangerous man-made global warming remains an uphill struggle. For decades, the climate debate has been obfuscated by cherry-picking, spin-doctoring and scaremongering by the United Nations' Intergovernmental Panel on Climate Change (IPCC) and other climate alarmists, including the environmental movement and mainstream media. Their massive campaign to overstate the threat of man-made warming has left its imprint on public opinion. But the tide seems to be turning. The Climate Conference fiasco in Copenhagen, the Climategate scandal and stabilization of worldwide temperatures since 1995 have given rise to growing doubts about the putative threat of "dangerous global warming" or "global climate disruption." Indeed, even Phil Jones, director of the Universi...
Brian Kummet, a forester for the tribe, calls the 400-acre Tramway "a flagship project" for the practice known as carbon sequestration, in which trees are planted to capture atmospheric carbon dioxide - the greatest contributor to global warming. Studies show that an acre of Western forest captures one to two metric tons of carbon dioxide annually, synthesizing it into food for growing plants. The Nez Perce have 29 forest-restoration projects dedicated to carbon sequestration - a total of 5,000 acres. During the projects' 80-year lifespan, the trees will soak up the equivalent of a year's worth of carbon dioxide from a half-million cars and SUVs. To date, companies have paid the Climate Trust to offset more than 1.6 million metric tons of carbon dioxide. The Trust's executive director, ...
Dairy farmers, who were pushed past the breaking point in many cases by low milk prices, now have seen prices soar due to droughts in other parts of the world and reductions in domestic supplies. [...]'s atmospheric carbon dioxide buildup, aka climate change, dba global warming - extra energy in the weather system that tends to produce extremes of many kinds.
Over the past several months, DWEJ and other environmental justice advocates have worked closely on the federal climate legislation - H.R. 2454 (American Clean Energy and Security Act of 2009) and S.1733 (Clean Energy Jobs and America Power Act) to ensure that stringent measures are adopted to closely monitor and regulate cap and trade, significantly increase green job opportunities for historically under-represented communities, and substantially curtail carbon emissions in low-income communities. On Thursday and Friday, Dec. 17-18, many of the world leaders arrived in Copenhagen. On Friday, after stalled talks, President Obama met with China, India, Brazil and South Africa, and created the Copenhagen Accord. Although this document did not assign a deadline for establishing a binding a...

The theory of global warming is that use of fossil fuels such as oil, gasoline, coal, and natural gas (the foundation of the Industrial Revolution) is increasing atmospheric concentrations of carbon dioxide (C02). [...] let's pretend that any of these alternative energy sources could become technologically feasible.
The evidence for a consistent recent warming trend and a rapid buildup of atmospheric carbon dioxide is now virtually irrefutable. Because carbon-based gasses are likely to have a "greenhouse effect," it is perfectly plausible that a reduction in human carbon emissions could halt or even reverse the warming trend.
According to data from the National Oceanic and Atmospheric Administration, the National Space Administration, Woods Hole Oceanographic Institution and other credentialed researchers, there is no question the atmosphere is holding a record concentration of carbon dioxide and that the atmosphere, land surfaces and oceans have reached record average temperatures. The temperature gain is fully predictable, since Carbon dioxide blocks the escape of radiated heat back into space. This is the so-called greenhouse effect. NOAA data show an unprecedented increase of Carbon dioxide in the atmosphere of more than 23 percent in the past 50 years, making the atmospheric concentration of Carbon dioxide greater by one-third than it was around 1850, and more than 30 percent higher than at any...
