China, the world's biggest emitter of greenhouse gases, has pledged to reduce its carbon emission intensity by 40-45 per cent by 2020 from the 2005 level in a new plan unveiled just ahead of a UN climate summit in New York.
The vast mangrove forest in the Sunderbans is fast losing its capacity to absorb carbon dioxide, one of the main greenhouse gases, from the atmosphere due to rise in the salinity of water, rampant deforestation and pollution, a study has found.
Biofuels from corn residue may be less beneficial than previously thought as a study has found using corn crop residue to make ethanol and other biofuels reduces soil carbon and can generate more greenhouse gases than gasoline.
Researchers have suggested that using urban adaptation strategies like green roof, cool roof, and hybrid technologies can help offset not only future climate warming due to urban expansion but also temperature increases driven by greenhouse gases.
Here comes an exciting new laser that can detect very low concentrations of gases - paving the way for accurately analysing breath for disease diagnosis and remote sensing of critical greenhouse gases.
