UN chief Antonio Guterres recently warned that we face "a direct existential threat" if we do not rapidly switch from fossil fuels by 2020. The failure to do so will mean "runaway climate change,"and he has deplored the lack of global leadership by politicians to address the issue. "We need to put the brake on deadly greenhouse gas emissions and drive climate action," he said, pointing out that all around the world we are experiencing record-breaking temperatures, extreme heatwaves, storms, floods, and wildfires which are leaving a "trail of death and devastation."
