Congress About to Get Hit in the Head With the Price of Climate Change

Let our journalists help you make sense of the noise: Subscribe to the Mother Jones Daily newsletter and get a recap of news that matters.

A few weeks ago I linked to a piece Chris Mooney did for us about the effect of climate change on Hurricane Sandy. Chris made the point that although you can argue about whether climate change is responsible for any particular hurricane, there’s no question that climate change is responsible for a rise in sea level, which makes the damage from hurricanes much worse than it otherwise would be. And that includes Hurricane Sandy. “There is 100 percent certainty that sea level rise made this worse,” sea level expert Ben Strauss said. “Period.”

Well, it turns out the news is even worse than that. A new study using satellite data suggests that, if anything, forecasts of sea level rise in the most recent IPCC reports have been too low. Global warming is about where the predictions say it should be, but the amount of warming we’re getting is increasing sea level a lot faster than we thought it would. The chart below shows the difference between reality and the two most recent IPCC forecasts.

This unexpected rise isn’t due to medium-term variability, and it’s not due to a temporary release from Greenland’s ice sheets. The most likely explanation is simply that sea level rise is more sensitive to global warming than we thought. Congress—along with all the skeptics who argue that it’s cheaper to pay the price of climate change than it is to stop it—should think about this when they’re considering the $100 billion in disaster funds that northeastern states are requesting to clean up after Sandy.

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.
