Truthout combats corporatization by bringing you trustworthy news: click here to join the fight!
On Sunday, 19 members of the Granite Mountain Hotshots, an elite wildfire-fighting team, were killed when a burst of wind pushed a blazing forest fire in their direction.
Their deaths were a tragedy, but the biggest tragedy is that they could have been prevented. They could have been prevented if we listened to the scientists who told us nine years ago that global warming would lead to harsh droughts, baking heat, and deadly forest fires.
In 2004, Liza Sloan, a professor of Earth science at the University of California at Santa Cruz, published a study in the journal Geophysical Research titled “Disappearing Arctic sea ice reduces available water in the American west.” In that article, which she wrote with graduate student Jacob Sewall, Sloan predicted that as Arctic sea ice melted because of accelerating climate change, the American west would become increasingly susceptible to the kind of lengthy droughts and heat waves we’re seeing right now in the summer of 2013.The same kind of droughts and heat waves that caused the fire that killed 19 Granite Mountain Hotshots.
The logic behind their study was simple. When cool sea ice melts, it makes it easier for warm air to rise out of the ocean over the polar regions and funnel up into the atmosphere. Sewall explained the process to the UC Santa Cruz newspaper at the time:
“The sea ice acts like a lid over the ocean surface during the winter, blocking the transfer of heat from the ocean to the atmosphere… Where the sea ice is reduced, heat transfer from the ocean warms the atmosphere, resulting in a rising column of relatively warm air.”
As the two scientists discovered, that change in normal arctic air patterns in turn pulls normal winter storm systems from the American west up north over Canada, significantly reducing annual rainfall throughout the American west .
When Sloan and Sewall ran their data through one of the National Center for Atmospheric Research’s modeling computers, they found that such a shift would lead to as much as a 30 percent or a 17 percent drop in precipitation by 2050 in some parts of the Western United States. In other words: drought.
A new and improved version of Sloan and Sewall’s study came out in 2005, concluding pretty much the same thing: that melting Arctic sea ice would lead to drastic reductions in rainfall in the American West.
No one listened to Jacob Sewall and Lisa Sloan when they published their study almost a decade ago, but we should have. Their predictions are coming true. The Western U.S. is currently in the middle of a record busting heat-wave and drought.
When contacted by ThinkProgress to comment on the current climate crisis west of the Mississippi, Jacob Sewall said that current conditions match up with or are even worse than what he and Sloan predicted almost a decade ago. Arctic sea ice reached its projected concentration in 2011, a shocking fact when you consider that those predictions were for the year 2050. And precipitation levels in places like California are 15 percent lower than what Sloan and Sewell originally estimated, that doesn’t mean their research was wrong. As Sewall told ThinkProgress, ““I think the hypothesis from 2004 and 2005 is being borne out by current changes. The only real difference is that reality is moving faster than we thought it would almost a decade ago.”
That’s right – faster. Terrifying stuff.
But that’s not even the scariest part. Sloan and Sewall didn’t even factor in the compounded effects of atmospheric greenhouse gasses on climate patterns in the West in their 2004 and 2005 studies. According to Sewall, “In a scenario with increased greenhouse gases, we would expect to see other effects on the climate that would interact with the effects of reduced sea ice.” That is, if fossil fuel companies continued to pump toxic carbons into the atmosphere – as they have in the nine years since Sewall and Sloan’s initial study – droughts would be even worse than their research predicted.
The debate is over.
As President Obama told students and Georgetown University last week, we don’t have time to listen to the “flat earth society” when it comes to climate change.
If you had an infection on your foot, you wouldn’t wait ten years and visit 99 different doctors before you found the one quack who says you don’t need to need to do anything about it. You’d take the advice of the first, second, and third, the 99 out of 100 doctors and fix the problem.
Global warming is real, global warming is deadly, and it’s worse than many of our best scientists predicted just nine years ago.
We need to listen to the 99 percent of the scientific community who know this before we miss another chance, like we did with the Western drought, to take preventative action to save lives and save communities.
We also need to turn scientific evidence into concrete public policy. We need to institute a nationwide carbon tax to make the fossil fuel industry pay to clean up its waste.
Every other industry in the country pays to dispose of their waste, and so should the companies that are singlehandedly destroying our planet.
We can’t resurrect the 19 firefighters who gave their lives in Arizona this weekend, but we can start to listen to what the scientific community is telling us about the health of our planet and we can start to push for policies that will stave off total climate disaster – and most importantly – save lives.
And the time to do that is now.
Truthout Is Preparing to Meet Trump’s Agenda With Resistance at Every Turn
Dear Truthout Community,
If you feel rage, despondency, confusion and deep fear today, you are not alone. We’re feeling it too. We are heartsick. Facing down Trump’s fascist agenda, we are desperately worried about the most vulnerable people among us, including our loved ones and everyone in the Truthout community, and our minds are racing a million miles a minute to try to map out all that needs to be done.
We must give ourselves space to grieve and feel our fear, feel our rage, and keep in the forefront of our mind the stark truth that millions of real human lives are on the line. And simultaneously, we’ve got to get to work, take stock of our resources, and prepare to throw ourselves full force into the movement.
Journalism is a linchpin of that movement. Even as we are reeling, we’re summoning up all the energy we can to face down what’s coming, because we know that one of the sharpest weapons against fascism is publishing the truth.
There are many terrifying planks to the Trump agenda, and we plan to devote ourselves to reporting thoroughly on each one and, crucially, covering the movements resisting them. We also recognize that Trump is a dire threat to journalism itself, and that we must take this seriously from the outset.
After the election, the four of us sat down to have some hard but necessary conversations about Truthout under a Trump presidency. How would we defend our publication from an avalanche of far right lawsuits that seek to bankrupt us? How would we keep our reporters safe if they need to cover outbreaks of political violence, or if they are targeted by authorities? How will we urgently produce the practical analysis, tools and movement coverage that you need right now — breaking through our normal routines to meet a terrifying moment in ways that best serve you?
It will be a tough, scary four years to produce social justice-driven journalism. We need to deliver news, strategy, liberatory ideas, tools and movement-sparking solutions with a force that we never have had to before. And at the same time, we desperately need to protect our ability to do so.
We know this is such a painful moment and donations may understandably be the last thing on your mind. But we must ask for your support, which is needed in a new and urgent way.
We promise we will kick into an even higher gear to give you truthful news that cuts against the disinformation and vitriol and hate and violence. We promise to publish analyses that will serve the needs of the movements we all rely on to survive the next four years, and even build for the future. We promise to be responsive, to recognize you as members of our community with a vital stake and voice in this work.
Please dig deep if you can, but a donation of any amount will be a truly meaningful and tangible action in this cataclysmic historical moment.
We’re with you. Let’s do all we can to move forward together.
With love, rage, and solidarity,
Maya, Negin, Saima, and Ziggy
