Currently, anthropogenic N 2 O emissions represent the largest contribution to ozone depletion. The study, published online 27 August in the journal Science , for the first time evaluated nitrous oxide emissions from human activities in terms of their potential impact on Earth’s ozone layer.

Our results suggest that gas-aerosol interactions play an important role in methane’s GWP, and hence our larger value would allow better optimization of climate change mitigation policies. Methane’s GWP may also change with time as air quality regulations alter the background state of tropospheric chemistry. Shindell et al.

It is an unpalatable truth that unless we can succeed in greatly reducing CO 2 emissions we are headed for a very uncomfortable and challenging climate future, and geoengineering will be the only option left to limit further temperature increases.

Mobile air conditioning systems are the single most important source of fluorinated greenhouse gases, due mainly to high emissions during their operation and their large numbers, noted Germany’s Umweltbundesamt in a 2009 publication on CO 2 systems.

As we confront the enormous challenge of climate change, we should take inspiration from even the most unlikely sources.
