Trumpís Pick To Replace Former Exxon CEO As Secretary Of State Is A Bigger Climate DenierMike Pompeo, President Donald Trumpís pick to replace sacked Secretary of State Rex Tillerson, threatens to bring a hard-line brand of climate change denialism to Foggy Bottom for the first time. The current CIA director, named early Tuesday as the nominee to be the nationís top diplomat, has long rejected the widely-accepted science behind man-made global warming, dashing hopes that the United States might reverse its decision to leave from the Paris climate accord before November 2020, when the deal allows the country to formally withdraw. In a twist, Tillerson, the former chief executive of Exxon Mobil Corp., turned out to be one of the most moderate voices on climate change in the Trump administration, despite his previous employerís role as an early and generous financier of the climate change denial movement.
