I'm not surprised that Bill Gates remains optimistic that we can avoid ecological disaster despite little progress toward reducing carbon emissions. But I am a bit surprised he won't take a tougher public line against President Trump.
Driving the news: Gates has met several times with Trump, most recently in March. And while he has yet to get concrete positive action from the president on climate or other issues close to his heart, he refuses to talk critically about the president. Pressed several times on the matter in an "Axios on HBO" interview, he briefly acknowledged areas where the executive branch hadn't taken action before quickly shifting to point out others who have acted — including Congress, business leaders and other countries.
