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.

Scientists used to think the Amazon was too wet to burn, but a warming Atlantic Ocean is drawing moisture away from the rainforest

MOYOBAMBA, Peru – Karina Pinasco watched in dismay as flames on a hillside at the edge of town lit up the sky one night in October 2010. A farmer had intended to clear a few hectares of land to plant coffee bushes, but the fire – set during an unusually hot, dry spell – quickly got out of hand.

Propelled by winds and high temperatures, it burned for 10 days, charring more than 250 acres of land.
