"For all the immediate challenges that we gather to address this week — terrorism, instability, inequality, disease — there’s one issue that will define the contours of this century more dramatically than any other, and that is the urgent and growing threat of a changing climate."
Those were President Obama's words at today's U.N. Climate Summit — a meeting of world leaders that showcased climate action commitments from governments, local leaders, and the private sector. In his remarks, the President detailed the ambitious clean energy investments and carbon emission reductions the U.S. has made, but made clear that all of the world's major economies also need to step up in order to protect our planet.
