To mark Earth Day yesterday, Barack Obama took a few moments “to celebrate the courageous, committed young leaders who are stepping up to save the one planet we’ve got”:

Young people all over the world are leading the way in the fight to protect our planet because they know their future depends on it. This Earth Day, I want to celebrate the courageous, committed young leaders who are stepping up to save the one planet we've got. — Barack Obama (@BarackObama) April 22, 2019

This generation of climate activists is tired of inaction, and they've caught the attention of leaders all over the world. So while this challenge is only getting more urgent, they show us the kind of action it'll take to meet this moment. — Barack Obama (@BarackObama) April 22, 2019

Is that so, Barry?

I'm old enough to remember when we had a President who cared about the Earth we live on. — Ed Krassenstein (@EdKrassen) April 22, 2019

Are you, Ed? Are you old enough to remember when we had a president who touted his election victory as “the moment that the rise of the oceans began to slow and our planet began to heal”?

What exactly did Barack Obama do for eight years, Ed, if climate change is still threatening to destroy the futures of “young people all over the world”? Is this his legacy? A world that only has 12 years to live?

This guy should run for President. He can give speeches about the moment the rise of the oceans began to slow and our planet began to heal. It'll be awesome. https://t.co/ikiuaiB2Sk — Matt Stoller (@matthewstoller) April 22, 2019

Sounds like @BarackObama forgot who was leader of the Free World for 8 years. — Red1Echo (@Red1Echo) April 22, 2019
