Trees Will Not Save Us From Climate Change

A new paper is getting a lot of attention for its claim that the earth has about 2 billion acres of land that are currently unused and could support the planting of 500 billion trees. Once the trees were grown, they’d capture about 205 gigatonnes of carbon. That sounds great, but let’s give it some context:

We have emitted about 450 gigatonnes of carbon since the start of the Industrial Revolution. At our current rate, we’ll add another 205 gigatonnes in less than 20 years.

If we could really get all the countries of the world to plant trees on currently unused land that’s suitable for reforestation, that would be great. But even if we went all out and got 100 percent cooperation, it would take 50 or 60 years for these forests to grow to maturity. Unless we do something about actual emissions, we will have added at least 500 gigatonnes of additional carbon by then, bringing us to total emissions of about a billion gigatonnes of carbon. The trees would make only a small difference.

By all means, we should take this seriously and plant lots of trees. Even 50 or 100 gigatonnes of carbon capture would be a lot. But don’t fool yourself into thinking this is any kind of free ticket. We still have to figure out a way to reduce actual emissions by a huge amount if we want to avoid planetary catastrophe.

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
