 Welcome to the Voice of America's Newswords. World leaders met in Glasgow, Scotland recently for the United Nations COP26 climate conference. Kickstart. Leaders spoke of the dangerous rise in the Earth's temperature and actions needed to reduce carbon in the atmosphere. British historian David Attenborough urged leaders to work together to kickstart a global climate recovery. Here, kickstart means to act fast and forcefully toward a goal. It is also how you turn on a motorcycle using your foot to push down a start pedal.
