Arctic stratospheric clouds unrelated to tropospheric temperature: ‘Radiative cooling (and warming) isn’t a key effect: a piece of the man-made climate change ‘lore’ is shaken’
'They found out that most of Arctic polar stratospheric clouds (PSCs) are linked with tropospheric clouds that are underneath...They also calculated the correlation coefficient between the occurrence of the PSCs and the top temperature of tropospheric clouds beneath them. They found no correlation!' -- 'Our findings suggest that Arctic PSC formation is connected to adiabatic cooling, i.e. dynamic effects rather than radiative cooling'
