Some areas experienced historic floods, others saw historic droughts. Is climate change to blame?
Natural Resources Defense Council
A once-in-five-hundred-year flood inundated the Mississippi River valley. A once-in-a-century drought in Texas shriveled the summer's crops and sparked sweeping forest fires. The deadliest tornado season on record tore communities to splinters. 2011 was clearly a year of extreme weather.
Perhaps it is a sign of the pending 2012 apocalypse, but more likely, it is the result of a changing climate that is amplifying extremes. The chart above marks more than 2,900 separate weather records broken this year, and these records were costly. In all, Mother Nature inflicted $52 billion dollars in damage on the United States.
However, 2011 is not the most expensive natural disaster year on record. That distinction belongs to 2005, the year Hurricanes Katrina and Rita caused more than $150 billion in destruction along the Gulf Coast. The difference is that 2005 had only five disasters that reached the billion dollar mark; 2011 had 12, and according to the National Oceanic and Atmospheric Administration, that sets a new record.
Two of the most consequential weather stories of the year were the drought in Texas and the tornado season in the Midwest. For most of the spring, summer, and fall, the Lone Star state was plagued by exceptional drought -- the highest level recorded by the U.S. drought monitor. The situation has eased somewhat in recent weeks, but climatologists say that because of the persistent pattern of La Niña (cooling off the coast of South America influencing the jet stream over North America), the drought is likely to linger into the new year.
The impacts of the record-breaking summer were enormous. Texas reservoirs sank to their lowest levels in years, even revealing long-forgotten underwater ghost towns. Authorities began predicting long-term water shortages in the state. Crops withered. Cattle herds died in the sun, causing the price of beef and other staples to increase across the country. Nearly half a billion trees perished for lack of rain. On this map comparing average temperature and average rainfall for Texas summers, it is not difficult to find the outlier.
And of course, some of the most powerful images of nature's destruction this year came from Joplin, Missouri, where an EF-5 tornado killed 159 people and destroyed 700 homes. But this was only one of several deadly tornado outbreaks in 2011. In total, 552 Americans died in twisters this year, 12 times the number of tornado deaths of last year and the most since the 1950s.
While it is hard to blame all of this meteorological activity on global warming, 2011 provides evidence of a planet with a wilder climate.
"This year we had three weather events that matched or exceeded three U.S. weather extremes," Jeff Masters, a meteorologist and founder of The Weather Underground blog, says. The Mississippi flood was higher than any other, the Texas drought was drier than any other, and the tornado season was deadlier than any other. "It boggles my mind."
Additionally, Masters finds the records broken this year to be indicative of a more extreme planet. "Fifty-six percent of the U.S. had a top 10 percent wettest or driest year. That's a record." That divergent pattern is to be expected with climate change -- the wet areas will grow wetter, the dry areas drier.
These billion dollar disasters are only likely to increase in the coming years, Masters says, and population growth and increasing wealth factor in as well. If there are more structures to destroy, one storm will cause increasing amounts of damage.
"The climate has changed," Kevin Trenberth, Distinguished Senior Scientist at the National Center for Atmospheric Research, tells me via email. He says since the 1970s, the water vapor over the oceans has increased by 4 percent. That water vapor acts as fuel to weather systems, contributing to the severity of the Mississippi flood, and to the thunderstorms which produced the spring's tornadoes.
"Hurricane Irene flooding had a component (5 to
10 percent) from human-induced global warming," he says. "It may not sound like much but it is often the straw that breaks the camel's back."
Here's a recap of the some of the top weather disasters in 2011. (This list is limited to the U.S. The rest of the world had its own share of nature-inflicted tragedy this year, including the 9.0 Japanese earthquake that killed 10,000 people and cost $309 billion.)
Today’s empires are born on the web, and exert tremendous power in the material world.
Mark Zuckerberg hasn’t had the best week.
First, Facebook’s Free Basics platform was effectively banned in India. Then, a high-profile member of Facebook’s board of directors, the venture capitalist Marc Andreessen, sounded off about the decision to his nearly half-a-million Twitter followers with a stunning comment.
“Anti-colonialism has been economically catastrophic for the Indian people for decades,” Andreessen wrote. “Why stop now?”
After that, the Internet went nuts.
Andreessen deleted his tweet, apologized, and underscored that he is “100 percent opposed to colonialism” and “100 percent in favor of independence and freedom.” Zuckerberg, Facebook’s CEO, followed up with his own Facebook post to say Andreessen’s comment was “deeply upsetting” to him, and not representative of the way he thinks “at all.”
By announcing the first detection of gravitational waves, scientists have vindicated Einstein and given humans a new way to look at the universe.
More than a billion years ago, in a galaxy that sits more than a billion light-years away, two black holes spiraled together and collided. We can’t see this collision, but we know it happened because, as Albert Einstein predicted a century ago, gravitational waves rippled out from it and traveled across the universe to an ultra-sensitive detector here on Earth.
This discovery, announced today by researchers with the Laser Interferometer Gravitational-wave Observatory (LIGO), marks another triumph for Einstein’s general theory of relativity. And more importantly, it marks the beginning of a new era in the study of the universe: the advent of gravitational-wave astronomy. The universe has just become a much more interesting place.
Once it was because they weren’t as well educated. What’s holding them back now?
Though headway has been made in bringing women’s wages more in line with men’s in the past several decades, that convergence seems to have stalled in more recent years. To help determine why, Francine D. Blau and Lawrence M. Kahn, the authors of a new study from the National Bureau of Economic Research parse data on wages and occupations from 1980 to 2010. They find that as more women attended and graduated college and headed into the working world, education and professional experience levels stopped playing a significant role in the the difference between men and women’s wages. Whatever remains of the discrepancy can’t be explained by women not having basic skills and credentials. So what does explain it?
By mining electronic medical records, scientists show the lasting legacy of prehistoric sex on modern humans’ health.
Modern humans originated in Africa, and started spreading around the world about 60,000 years ago. As they entered Asia and Europe, they encountered other groups of ancient humans that had already settled in these regions, such as Neanderthals. And sometimes, when these groups met, they had sex.
We know about these prehistoric liaisons because they left permanent marks on our genome. Even though Neanderthals are now extinct, every living person outside of Africa can trace between 1 and 5 percent of our DNA back to them. (I am 2.6 percent Neanderthal, if you were wondering, which pales in comparison to my colleague James Fallows at 5 percent.)
This lasting legacy was revealed in 2010 when the complete Neanderthal genome was published. Since then, researchers have been trying to figure out what, if anything, the Neanderthal sequences are doing in our own genome. Are they just passive hitchhikers, or did they bestow important adaptations on early humans? And are they affecting the health of modern ones?
The city has filed a suit demanding $500 in payment for emergency treatment for the boy after a police officer fatally shot him.
Updated on February 11 at 2:34 p.m.
What’s more outrageous than having a police officer shoot an unarmed 12-year-old, failing to provide medical care, keeping his family forcibly from the scene, and then declining to indict the officer for the death? In most cases, little. But the city of Cleveland has found a way: It is suing Tamir Rice’s family for not paying the ambulance bill after a Cleveland cop shot and killed the boy in November 2014.
As the Scene reports, Cleveland has filed a claim in probate court, seeking $500 from Rice’s estate to pay for emergency medical services rendered after Officer Timothy Loehmann fatally shot the boy. The charge is especially galling because Loehmann and another officer apparently had no training or equipment to provide aid to Rice after they shot him. They did nothing for four minutes until an FBI agent who happened to be nearby took over.
If Bernie Sanders is serious about a political transformation in America, he needs a better plan.
If there’s one thing that fires up Bernie Sanders supporters—and makes his detractors roll their eyes—it’s his call for a “political revolution.” To his base, it’s the very point of his anti-establishment, anti-elite candidacy. To his critics, it’s the very embodiment of his campaign’s naïve impracticality and vagueness.
But now that voters in Iowa and New Hampshire have spoken, it’s time to take the idea of political revolution more seriously—more seriously, indeed, than Sanders himself appears to have. It’s time to ask: What exactly would it take?
It starts with Congress. And here it’s instructive to compare Sanders and Donald Trump. Both rely on broad, satisfying refrains of “We’re gonna”: We’re gonna break up the big banks. We’re gonna make Mexico build the wall. We’re gonna end the rule of Wall Street billionaires. We’re gonna make China stop ripping us off.
When four American women were murdered during El Salvador’s dirty war, a young U.S. official and his unlikely partner risked their lives to solve the case.
On December 1, 1980, two American Catholic churchwomen—an Ursuline nun and a lay missionary—sat down to dinner with Robert White, the U.S. ambassador to El Salvador. They worked in rural areas ministering to El Salvador’s desperately impoverished peasants, and White admired their commitment and courage. The talk turned to the government’s brutal tactics for fighting the country’s left-wing guerrillas, in a dirty war waged by death squads that dumped bodies in the streets and an army that massacred civilians. The women were alarmed by the incoming Reagan administration’s plans for a closer relationship with the military-led government. Because of a curfew, the women spent the night at the ambassador’s residence. The next day, after breakfast with the ambassador’s wife, they drove to San Salvador’s international airport to pick up two colleagues who were flying back from a conference in Nicaragua. Within hours, all four women would be dead.
The number of American teens who excel at advanced math has surged. Why?
On a sultry evening last July, a tall, soft-spoken 17-year-old named David Stoner and nearly 600 other math whizzes from all over the world sat huddled in small groups around wicker bistro tables, talking in low voices and obsessively refreshing the browsers on their laptops. The air in the cavernous lobby of the Lotus Hotel Pang Suan Kaew in Chiang Mai, Thailand, was humid, recalls Stoner, whose light South Carolina accent warms his carefully chosen words. The tension in the room made it seem especially heavy, like the atmosphere at a high-stakes poker tournament.
Stoner and five teammates were representing the United States in the 56th International Mathematical Olympiad. They figured they’d done pretty well over the two days of competition. God knows, they’d trained hard. Stoner, like his teammates, had endured a grueling regime for more than a year—practicing tricky problems over breakfast before school and taking on more problems late into the evening after he completed the homework for his college-level math classes. Sometimes, he sketched out proofs on the large dry-erase board his dad had installed in his bedroom. Most nights, he put himself to sleep reading books like New Problems in Euclidean Geometry and An Introduction to Diophantine Equations.
Why the Syrian war—and the future of Europe—may hinge on one city
This week, the Syrian army, backed by Russian air strikes and Iranian-supported militias including Hezbollah, launched a major offensive to encircle rebel strongholds in the northern city of Aleppo, choking off one of the last two secure routes connecting the city to Turkey and closing in on the second. This would cut supplies not only to a core of the rebellion against Syrian President Bashar al-Assad, but also to the city’s 300,000 remaining civilians, who may soon find themselves besieged like hundreds of thousands of others in the country. In response, 50,000 civilians have fled Aleppo for the Turkish border, where the border crossing is currently closed. An unnamed U.S. defense official toldThe Daily Beast’s Nancy Youssef that “the war is essentially over” if Assad manages to seize and hold Aleppo.
After the New Hampshire landslide, the Democrats will debate for the first time on equal footing.
Who’s the Democratic front-runner now?
When Hillary Clinton and Bernie Sanders meet in Milwaukee tonight, you might think it’s Sanders. The sixth Democratic debate comes just three days after the Vermont senator’s landslide win in the New Hampshire primary, and the only question seems to be just how aggressive Clinton will be in going after him.
The former secretary of state was clearly humbled, if not outright humiliated, in the state that had once given both her and her husband new life in past presidential campaigns. Sanders had been expected to win handily, but his 22-point margin was even larger than forecast and cut across almost all demographics: Not only did he dominate among his core group of younger voters, but he even won among women overall, according to exit polls.
