“Climate change war” is not a metaphor

The U.N. Intergovernmental Panel on Climate Change has just completed a series of landmark reports that chronicle an update to the current state of consensus science on climate change. In a sentence, here’s what they found: On our current path, climate change could pose an irreversible, existential risk to civilization as we know it -- but we can still fix it if we decide to work together.

But in addition to the call for cooperation, the reports also shared an alarming new trend: Climate change is already destabilizing nations and leading to wars.

That finding was highlighted in this week’s premiere of Showtime’s new star-studded climate change docu-drama Years of Living Dangerously. In the series’ first episode, New York Times columnist Thomas Friedman traveled to Syria to investigate how a long-running drought has contributed to that conflict. Climate change has also been discussed as a “threat multiplier” for recent conflicts in Darfur, Tunisia, Egypt, and future conflicts, too.

Climate change worsens the divide between haves and have-nots, hitting the poor the hardest. It can also drive up food prices and spawn megadisasters, creating refugees and taxing the resiliency of governments.

When a threat like that comes along, it’s impossible to ignore. Especially if your job is national security.

In a recent interview with the blog Responding to Climate Changeretired Army Brig. Gen. Chris King laid out the military’s thinking on climate change:

“This is like getting embroiled in a war that lasts 100 years. That’s the scariest thing for us,” he told RTCC. “There is no exit strategy that is available for many of the problems. You can see in military history, when they don’t have fixed durations, that’s when you’re most likely to not win.”

In a similar vein, last month, retired Navy Rear Adm. David Titley co-wrote an op-ed for Fox News:

The parallels between the political decisions regarding climate change we have made and the decisions that led Europe to World War One are striking -- and sobering. The decisions made in 1914 reflected political policies pursued for short-term gains and benefits, coupled with institutional hubris, and a failure to imagine and understand the risks or to learn from recent history.

In short, climate change could be the Archduke Franz Ferdinand of the 21st century.

Earlier this year, while at the American Meteorological Society annual meeting in Atlanta, I had a chance to sit down with Titley, who is also a meteorologist and now serves on the faculty at Penn State University. He’s also probably one of the most fascinating people I’ve ever spoken with. Check out his TEDxPentagon talk, in which he discusses how he went from “a pretty hard-core skeptic about climate change” to labeling it “one of the pre-eminent challenges of our century.” (This interview has been lightly edited and condensed.)

U.N. climate report: We must focus on “decarbonization,” and it won’t wreck the economy

Rajendra Pauchari, chair of the IPCC, tells us to get a move on.

So far, climate change is following the plot of an epic disaster movie.

In the last few years, giant megafires have burned out of control, we’ve been hit with superstorms, our fields have wilted, and there’s barely any ice left at the North Pole. Despite all we think we’ve done so far to change course, emissions are still increasing.

We’ve now advanced to the part when the world’s best scientists emerge from their conclave to announce a range of possible plans that could save us from going over the climate cliff.

On Sunday, they made their announcement, calling for a “fundamental decarbonization” of the world economy. Sounds daunting, but overwhelmingly the message from scientists to the world was one of hope.

Unlike so many previous climate change reports, this time there’s significant good news: The world doesn’t need to sacrifice economic growth to get the job done. The task can largely be achieved with existing technology. And hey, we’ll end up with a better planet at the end, too.

Now, we just need to take action. World, this is our Ben Affleck moment.

Snow’s melting in Alaska and pelting the South. What’s going on?

Earlier this month, squeals of delight (and/or searing pain) gripped much of the country as we were collectively introduced to the wonders of the polar vortex. But now the novelty’s over, and for the second time this month, an extreme weather pattern is sending Arctic weather toward the Deep South.

An uncommonly sharp kink in the jet stream is partly responsible for plunging more than half of the United States into the freeze. Meanwhile, (and for the same reason), Alaska is toasty warm. But we’ll get to that in a minute.
