But some scientists are now warning that the impact of radiation caused by aircraft condensation trails (contrails) could even be more significant. Contrails, which heighten the effect of global ...
Contrails, as these stripes are called, are caused by jet engine exhaust. They are worse for the climate than aviation’s CO2 emissions. William Todts is Executive Director of Transport & Environment ...
Fewer aromatic hydrocarbons in the fuel means less soot in emissions. As soot particles act as condensation nuclei for ice crystals in contrails, less soot in aircraft exhaust gases means fewer ice ...
Persistent contrails can spread, merge and form aircraft-induced cirrus, which can have a climate-warming effect. Credit: Frank Wagner/Getty Images In an August press release announcing the ...
These persistent contrails, as they are known, help to reflect solar radiation back to space, which has a cooling effect. But they also block heat from escaping from… Receive a weekly dose of ...
Contrails from hydrogen-fueled aircraft are expected to form more readily and be more widespread than those from jet-fueled aircraft but will have less of a climate impact due to their lower ...
This is called ordinal time preference. It also helps to explain why demand curves are downward sloping in microeconomic models since each additional unit of a product or service is put toward a ...
