KIT researchers prove global increase of ultrafine particles from exhaust gases of fossil fuels and warn of major weather effects Strong precipitation or extreme drought – the frequency of extreme weather events is increasing worldwide. Existing climate models, however, do not adequately show their dynamics. Researchers of Karlsruhe Institute of Technology (KIT) assume that ultrafine particles in the atmosphere have a significant impact on cloud physics and, hence, on weather. Their aircraft measurements confirm an increase in particle number emissions in spite of a decreasing coarse fine dust concentration and blame it to the combustion of fossil fuels in exhaust gas cleaning systems. Junkermann piloted KIT’s ultralight aircraft D-MIFU, the smallest manned research aircraft in the ...
