Before this study, we didn’t know how fast that carbon could potentially be released from permafrost, and how this feedback to climate would change over time. An understanding of the rate of carbon release is necessary to estimate the strength of positive feedback to climatechange, a likely consequence of permafrost thaw.
Since carbon dioxide emissions are highly correlated with fuel consumption (FC), fuel consumption regulation is a useful policy instrument to combat climatechange. —Dror et al.

Satellite records from 2004 to 2009 showed a pattern of increases in the chemical’s presence in the stratosphere each summer, correlating with the timing of the monsoon. When sulfur rises into the stratosphere, it can lead to the creation of small particles called aerosols that are known to influence the ozone layer. William Randel.
