Global Warming

Curbing greenhouse gas emissions from cultivated fields may require going beyond cutting back on nitrogen fertilizer and changing crop rotation cycles, according to research by Agricultural Research Service scientists. Jane Johnson, a soil scientist at the ARS North Central Soil Conservation Research Laboratory in Morris, Minn., is looking for practical ways to keep carbon in the soil and reduce greenhouse gas emissions. In a...

It's easy to shrug off climate change deniers who use incomplete or inaccurate data in their arguments, but it's a harder pill to swallow when supposedly reputable organizations dupe us with exaggerated claims. Yet that's exactly what happened recently with the Intergovernmental Panel on Climate Change, which purportedly stretched the truth by claiming that deforestation is responsible for 20% of all CO2 produced by people. In a new study...  

BARCELONA, Spain (Reuters) - China should roughly halve its greenhouse gas emissions by 2050 as part of a strong assault on global warming, the head of the U.S. delegation at U.N. climate talks in Barcelona said on Thursday.  

The carbon dioxide emissions caused by the destruction of tropical forests have been significantly overestimated, according to a new study. The work could undermine attempts to pay poor countries to protect forests as a cost-effective way to tackle global warming.The loss of forests in countries such as Brazil and Indonesia is widely assumed to account for about 20% of all carbon dioxide produced by human activity – more than the world's...  

Tulane University has released a greenhouse gas emissions inventory, a tool that measures an institution’s impact on global climate change. The new inventory covers calendar years 2006-2008 and accounts for all Tulane's campuses in New Orleans, as well as campuses and other research buildings in Harahan, Covington and Belle Chasse, La., and in Houston and Biloxi.  

Some forest carbon-dioxide credits under a new UN forestry climate agreement may be worth less after text that protected forests was removed last month, according to an investor’s group, reports Bloomberg News. This could leave some companies who have bought certain forest carbon offsets feeling taken. The Carbon Markets & Investors Association (CMIA), an emissions-trading lobby group, [...]  

In today's news:Gore clears carbon dioxide of most blameBy Andrew Bolt, Australian Herald SunThis is big. Al Gore is now saying carbon dioxide isn’t actually to blame for most of the warming we saw until 2001:"Gore explored new studies - published only last week - that show methane and black carbon or soot had a far greater impact on global warming than previously thought. Carbon dioxide – while the focus of the politics of climate change...

http://www.diw.de/documents/publikationen/73/diw_02.c.298937.de/dp918.pdfAbstract: Methane is a major anthropogenic greenhouse gas, second only to carbon dioxide (CO2) in its impact on climate change. Methane (CH4) has a high global warming potential that is 25 times as large as the one of CO2 on a 100 year time horizon according to the latest IPCC report. Thus, CH4 contributes significantly to anthropogenic radiative forcing, although it has...  

Three years since the release of former Vice President Al Gore's Oscar-winning documentary "An Inconvenient Truth," Katie Couric asks Gore if we are moving in the right direction on climate change. Gore also offers his opinions on Afghanistan, and President Barack Obama's winning of the Nobel Peace Prize.  

Al Gore, the former American vice-president, yesterday hit back at critics who are labelling him the first "carbon billionaire" from his earnings as an investor in green technology, dismissing them as "global-warming deniers".  

The volume of greenhouse gases emitted by 40 industrialised countries that report under the United Nations Framework Convention on Climate Change increased by 1% in 2007. Between 1990 and 2007 emissions fell by 4% in these countries. Control of greenhouse gases varied widely over the period. Emissions in Spain rose by more than 53%, but in Germany they fell by more than 21%. Britain’s switch from coal- to gas-fired power stations has helped...  

I've been grappling with how and when to tell my six years old about man-made global warming, its claimed effect on his climate, and the implications for his world when he is my age. He has natural interest in weather events, and can tell me the geographic differences between tornadoes, cyclones and hurricanes, for example. Knowing he has gleaned all this under his own steam, driven by his own
