It’s past time for a real conversation about carbon pollution, and how much we are already paying. We know what’s happening, and we know why. But when talk finally turns to solutions, we always hear the same refrain: We can’t afford to do anything about climate change. The reality is that what we really can’t afford to do is nothing.

As climate activists, we’re accustomed to facing frightening facts. Global carbon emissions have never been higher. Wildfires in the U.S. burned a record number of acres this year. And this summer, Arctic sea ice reached an all-time seasonal low. As Americans, there’s a whole other suite of scary realities we now face: One in five children live in poverty. Millions are jobless. And income inequality continues to rise.

The Earth’s climate is on a precipice, and it appears now that we could tumble out of control into catastrophic changes that we can never reverse. International efforts to negotiate a solution are falling far short of what is required to avoid this climate disaster. And on top of this, global carbon markets, a vital policy instrument to fight climate change, are collapsing.

We need leadership. And if elected officials and governments are failing to lead, then all of us, everyday citizens, must step up to take their place.

That’s why I’m so excited to be joining one thousand individuals this week from around the world at our Climate Reality leadership training in Northern California. Together with our Chairman, former Vice President Al Gore, we will be training them to share the reality of climate change as leaders who encourage their communities to take action.

For weeks now, we have all been saying over and over “I’m too hot!” Well it’s a fact, not just a feeling — it is too hot. It’s also too rainy and too dry; our homes and farms are now more vulnerable than ever to drought and flooding, wildfires and mudslides. The media has been very busy telling us all about the weather and how “wacky” it’s been, but they’ve left out a crucial fact: that it is too hot because of climate change.

Recently, the Heartland Institute put up — and just as quickly pulled down after a firestorm of criticism — a truly bizarre billboard in Chicago attempting to equate climate science with radicals and murderers. Since the billboard was suddenly and unexpectedly empty, we thought we would take the opportunity to remind Heartland who is really on the fringe here.
