President Obama at the 2014 Climate Summit

He’s not Leonardo DiCaprio, but President Obama’s, another one of the leading men at yesterday’s 2014 Climate Summit, speech on climate change is well worth a watch or read.  He began with a sober assessment of the magnitude of the problem:

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.

He also recapped what America has been doing to meet the climate change challenge:

Over the past eight years, the United States has reduced our total carbon pollution by more than any other nation on Earth.  But we have to do more.  Last year, I issued America’s first Climate Action Plan to double down on our efforts.  Under that plan, my administration is working with states and utilities to set first-ever standards to cut the amount of carbon pollution our power plants can dump into the air.  And when completed, this will mark the single most important and significant step the United States has ever taken to reduce our carbon emissions. 

And, he spoke about the international collaboration underway: 

Just a few minutes ago, I met with Chinese Vice Premier Zhang Gaoli, and reiterated my belief that as the two largest economies and emitters in the world, we have a special responsibility to lead.  That’s what big nations have to do.
