United States: Trump mocked renewables as a "joke," praised "clean, beautiful coal" and declared climate change the "greatest con job ever." But some of his sharpest barbs were reserved for climate change -- seemingly tailored to a political base that sees climate science as another front in America's culture wars, ahead of a major climate announcement expected Wednesday from the United States' chief geopolitical rival China. Trump called the technology "so pathetic, so bad," and boasted that he had instead "unleashed" massive efforts to drill for new oil, gas and coal reserves. During his first term, President Trump abandoned the Paris climate accord. "Climate change is here, it's costly, and people need real solutions, not propaganda designed to boost the profits of fossil fuel polluters."
