By John Murawski, Real Clear Investigations - The climate dissenters are pressing their case as Pres. Biden, UN officials, and climate action advocates in media and academia argue that the “settled science” demands a wholesale societal transformation. That means halving U.S. carbon emissions by 2035 and achieving net zero emissions by 2050 to stave off the “existential threat” of human-induced climate change... In response last month, more than 1,600 scientists, among them two Nobel physics laureates, Clauser and Ivar Giaever of Norway, signed a declaration stating that there is no climate emergency, and that climate advocacy has devolved into mass hysteria.
