Researchers at the University of Kansas led a study in which they gathered emissions data from hundreds of US cities that either conducted a greenhouse gas emissions inventory, or reported they employed sustainability staff. The cities that conducted an inventory showed a statistically significant reduction in emissions between 2010 and 2015, while those with sustainability staff did not. Little research had previously been done to gauge effects of such measures and show that addressing emissions is meaningful, researchers argue.

Hotter temperatures may render natural insect repellents less effective against mosquitoes, according to a new study. 

New Delhi's air pollution is more severe than previously estimated with particles absorbing atmospheric water vapour leading to particulate matter levels across the city being underestimated by up to 20%.

Second-hand electric cars may be close to a “tipping point” where they become more popular than equivalent petrol and diesel cars in the UK, new research shows.

Research published in early online format in journals of the American Meteorological Society discusses topics including increasing energy costs due to climate change in Texas; increasing atmospheric rivers; malaria predication; and whether global warming could be reversed in certain parts of the world if greenhouse gas emissions go down.
