Clouds may have a net warming or cooling effect on climate, depending on their thickness and altitude. Artificially formed clouds called contrails form due to aircraft effluent. In a cloudless sky, contrails are thought to have minimal effect on climate. But what happens when the sky is already cloudy? In a new study published in the journal Nature Communications, scientists at ACES and colleagues from the UK show that contrails that are formed within existing high clouds increase the reflectivity of these clouds, i.e. their ability to reflect light. The researchers hope that their discovery offers important insights into the influence of aviation on climate.

We blame air rage on long flight delays, shrinking seats and a general decline in civility. But the first empirical research study into the phenomenon pegs another culprit -- class inequality -- for the reason passengers lose it when taking to the so-called friendly skies.

Thanks to a close collaboration between the Swiss Federal Laboratories for Materials Science and Technology (Empa), SR Technics and the Federal Office of Civil Aviation (FOCA), Switzerland is setting an international benchmark by developing a method for measuring emissions of fine particulate matter from aircraft engines. The Committee on Aviation Environmental Protection of the International Civil Aviation Organization (ICAO) recently approved a preliminary standard governing the emission of particulates by aircraft engines.
