Cutting soot, ozone will keep climate change in check, says UN

The simplest way to address climate change in the short term may be to reduce soot, methane, and ground level ozone emissions, according to a United Nations Environment Program report discussed today in Nairobi, Kenya.

Curbing emissions of these could reduce projected climate warming by 0.5 degrees Celsius by 2070, states the report. The cuts could be achieved using existing technology and current policies, and they would help protect climate, public health, water and food security, and ecosystems.
