Climate change: Arctic passes 400 parts per million milestone
Show
Arctic monitoring stations show carbon dioxide levels are now above 400 parts per million. Carbon dioxide is the chief climate-change gas and stays in the atmosphere for 100 years. Before the Industrial Age, carbon dioxide levels were 275 ppm.

The world's air has reached what scientists call a troubling new milestone for carbon dioxide, the main global warming pollutant. ... Read more about Climate change: Arctic passes 400 parts per million milestone

Soil erosion increasing global warming threat-UNEP

LONDON, Feb 13 (Reuters) - Global warming will get worse as agricultural methods accelerate the rate of soil erosion, which depletes the amount of carbon the soil is able to store, a United Nations' Environment Programme report said on Monday.

Soil contains huge quantities of carbon in the form of organic matter. which provides nutrients for plant growth and improves soil fertility and water movement.

The top metre of soil alone stores around 2,200 billion tonnes of carbon, which is three times the level currently held in the atmosphere, said the UNEP Year Book 2012. ... Read more about Soil erosion increasing global warming threat-UNEP
