Ozone Hinders Plants’ Ability to Absorb Carbon Dioxide

August 11, 2007 – 7:46 am

TreeHugger
Ozone — best known for filtering out harmful UV light as a component of the Earth’s stratosphere — could dramatically reduce plants’ ability to act as a carbon sink and thus cause further accumulation of greenhouse gases in the atmosphere, according to a new study published in Nature. In addition to damaging human tissues (particularly […]

How large is the global carbon sink?

July 31, 2007 – 3:37 am

SciDev.net
The magnitude of the global carbon sink can be estimated by comparing the rate at which carbon is being emitted into the atmosphere — currently about 7 Gigatonnes a year, which we know from inventories of fossil fuel and biomass burning — with measurements of the […]

Falling into carbon sinks

June 22, 2007 – 3:00 am

A study released yesterday by the International Energy Agency estimates that China has now surpassed the US in polluting carbon emissions (see China may lead in greenhouse gases from today’s Los Angeles Times). Although some may take some solace in the US no longer being the lead global polluter, the drop in ranking has more […]
