On geological timescales, carbon dioxide enters the atmosphere through volcanism and organic matter oxidation and is removed through mineral weathering and carbonate burial. An analysis of ice-core CO2 records and marine carbonate chemistry indicates a tight coupling between these processes during the past 610,000 years, which suggests that a weathering feedback driven by atmospheric CO2 leads to a mass balance between CO2 sources and sinks on long timescales.

Atmospheric carbon dioxide levels greatly influence the Earth's climate. Evidence from ice cores and marine sediments suggests that over timescales beyond the glacial cycles, carbon fluxes are finely balanced and act to stabilize temperatures.

This report evaluates the initial trial phase of the EU Emissions Trading System and provides lessons for the EU moving forward as well as for the development of cap-and-trade programs in the United States.

Mumbai's suburban railway network may earn some brownie points in its efforts to overhaul the system to make it energy-efficient and travel-friendly. New braking and duct systems have been introduced

Russia will not accept binding caps on its greenhouse gas emissions under a new climate regime, currently being negotiated to succeed the Kyoto Protocol after 2012, top officials said on Monday. Kyoto puts a cap on the average, annual greenhouse gas emissions from 2008-12 for some 37 industrialised countries, including Russia. But former communist countries are well within their emissions targets, which are compared to 1990 levels, because their industries and carbon emissions subsequently collapsed after they struggled to adapt to free markets.

China has surpassed the US as the world's largest carbon emitter PIERRE MARIO FITTER According to recent reports from The Netherlands Environmental Assessment Agency and the University of California, Berkeley, China overtook the US as the world's largest carbon emitter in 2006.

It is well known that certain naturally occurring trace gases in our atmosphere trap radiant heat from the sun and give rise to the greenhouse effect. In the post-industrialisation era, some manmade greenhouse gases are being added to the atmosphere and are contributing to enhanced greenhouse gas effect or global warming. Global warming is not yet fully understood since it's a complex climate phenomenon. Carbon dioxide (CO2)

Sydney-based Ecocho founder Tim Macdonald had an idea; build a search engine based on Google and Yahoo technology and use the ad revenue to plant two trees for every 1,000 searches, offsetting tons of carbon dioxide.

Climate change and the carbon emissions seem inextricably linked. However, new research published in BioMed Central's open access journal Carbon Balance and Management suggests that this may not always hold true, although it may be some time before we reach this saturation point.
