"The sensitivity of the clouds to the ship exhaust was measured during the summer season, when most ship traffic occurs." "Contaminated clouds can act like a blanket. They warm the surface more than a pristine cloud. In our case, we found that a polluted cloud may lead to accelerated sea ice melt"
Arctic shipping alters cloud formation, study finds
A study led by the EPFL suggests that shipping emissions influence climate-relevant cloud formation and may affect regional climate processes far beyond the polar region.
