– “5 Top Moments From Rex Tillerson’s Hearing To Be Secretary Of State,” NPR.com, Jan 11, 2017, Jessica Taylor, 1/11/2017
CABINET/REX TILLERSON/STATE: "Tillerson also expressed his belief in climate change, but he wouldn't answer whether he believed humans were contributing to it.
'The risk of climate change does exist and the consequences of it could be serious enough that action should be taken,' Tillerson said. But asked by Corker whether it was worsened by human activity, Tillerson demurred, saying that 'the increase in the greenhouse gas concentrations in the atmosphere are having an effect' but that the 'ability to predict that effect is very limited.'
Sen. Tim Kaine, D-Va., his party's nominee for vice president against Trump, also pushed Tillerson on reports that Exxon Mobil had misled the public over climate change. Tillerson initially dodged, but Kaine pushed on: 'Do you lack the knowledge to answer my question or are you refusing to answer my question?'
'A little of both,' Tillerson quipped."
