US judge takes climate tutorial, backs oil firms

somewhat abrupt. Judge William Alsup, who in March took an unprecedented climate tutorial while hearing the lawsuit by two California cities against oil giants, has thrown it out despite accepting "the science behind global warming". San Francisco and Oakland had alleged that the firms were responsible for climate change and demanded they paid for coping with climate impacts. In his ruling, Alsup said the world has benefited from fossil fuels and it would be unfair to blame Chevron, ExxonMobil, Shell, BP and ConocoPhillips, in this case, for supplying "what we demanded". The problem deserves a solution on a more vast scale than can be supplied by a district judge, and is best addressed by the government's legislative and executive branches.
