For Earth Day, plant a tree

It’s Earth Day. How silly. We’re on this planet 24/7. But I guess after the Cuyahoga River went up in flames, it was time for a reminder.
Today, as we roast under a greenhouse gas blanket of around 400 ppm carbon dioxide, higher than it’s ever been for humans, the reminder’s still valuable.

Let’s start treating climate change like the enemy

Carbon dioxide in the atmosphere is hovering at a landmark 400 parts per million, a level never before experienced by human beings. Scientists say we’re playing with fire, risking the planet’s future if we don’t start to lower the greenhouse gas levels forcing climate change. How should we react to this news? First, we need to envision climate change more accurately, as a deadly threat.

What middle-size cities offer: Clean Air
