Declaring that "human influence on the climate system is clear," a U.N.-assembled panel of scientists reported Friday that "it is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century."
Scientists and government representatives are meeting in Stockholm this week to produce the latest high-level review of climate change. It's thousands of pages of material, and if it's done right, it should harbor very few surprises.
That's because it's supposed to compile what scientists know — and what they don't — about climate change. And that's left some scientists to wonder whether these intensive reviews are still the best way to go.

Scientists claim they have evidence that explains why lifestyle changes known to be good for you — low-fat diets, exercise, reducing stress — can lengthen your life.
Based on a small, exploratory study, researchers say these good habits work by preventing chromosomes in our cells from unraveling. Basically, they assert that healthy living can reverse the effects of aging at a genetic level.
How often do whales clean their ears? Well, never. And so, year after year, their earwax builds up, layer upon layer. According to a study published Monday, these columns of earwax contain a record of chemical pollution in the oceans.
The study used the earwax extracted from the carcass of a blue whale that washed ashore on a California beach back in 2007. Scientists at the Santa Barbara Museum of Natural History collected the wax from inside the skull of the dead whale and preserved it. The column of wax was almost a foot long.

A 4-year-old child who died of a rare brain infection in early August has led Louisiana health officials to discover that the cause is lurking in the water pipes of St. Bernard Parish, southeast of New Orleans.
There are a lot of fascinating details hiding below the surface in the world of color. For instance, scientists once thought the average color of the entire universe was turquoise — until they recalculated and realized it was beige.
In Japan, you wait at a stoplight until it turns from red to blue, even though it's the same green color as American stoplights.
And in World War II, the British painted a whole flotilla of warships pinkish-purple so they'd blend in with the sky at dusk and confuse the Germans. That's right — pink warships.
For several weeks now, two unmanned spy planes have been flying over the Atlantic on an unusual mission: gathering intelligence about tropical storms and hurricanes.
The two Global Hawk drones are a central part of NASA's five-year HS3 (Hurricane and Severe Storm Sentinel) Mission investigating why certain weather patterns become hurricanes, and why some hurricanes grow into monster storms.

Think about this: You wake up in New York City, decide to go for a stroll, head east after breakfast, and a short time later, still on foot, you find yourself in Morocco. Three hundred million years ago, you could have done that! There was no civilization back then, no cities, no countries, no people, but the land was there, so take a look at this map.
We've all had the experience of cruising along the highway only to come upon a police cruiser nestled behind some trees with the officer holding a radar gun. Even if you're driving the speed limit, your first reaction may be to slam on the brakes.
That technology is about 70 years old, and got its start right here in Connecticut.
Ever been caught doodling during a meeting a work? A boring class? You’re not alone. Did you get yelled at? “Get your head in the game! You’re distracted! You're not serious!"
Our guest Sunni Brown, author of The Doodle Revolution: Unlock the Power to Think Differently, says doodling involves a lot of the senses... movement, sound, and visuals… and, far from being a distraction, it actually can enhance learning.
This deceptively simple question is the single most important problem facing science as we probe more deeply into the fundamentals of the universe. All of the mysteries physicists and cosmologists face—from the Big Bang to the future of the universe, from the puzzles of quantum physics to the unification of forces and particles—come down to the nature of time. The fact that time is real may seem obvious. You experience it passing every day when you watch clocks tick, bread toast, and children grow. But most physicists, from Newton to Einstein to today’s quantum theorists, have seen things differently. The scientific case for time being an illusion is formidable. That is why the consequences of adopting the view that time is real are revolutionary.
Our brains are marvels, hard-wired by millions of years of evolution to boast a number of mental shortcuts, biases, and tricks that allow us to negotiate our complicated lives without overthinking every choice and decision we have to make.
Unfortunately, those ancient shortcuts don't always work to our advantage in our modern lives-when we don't also think slowly and rationally, those hard-wired habits can trip us up.
We all know love matters, but today, positive emotions expert Barbara Fredrickson joins Faith to show us just how much. Even more than happiness and optimism, love holds the key to improving our mental and physical health as well as lengthening our lives. Using research from her own lab, Fredrickson redefines love not as a stable behemoth, but as micro-moments of connection between people—even strangers. She demonstrates that our capacity for experiencing love can be measured and strengthened in ways that improve our health and longevity. Finally, she introduces us to informal and formal practices to unlock love in our lives, generate compassion, and even self-soothe.
The printing press, the pencil, the flush toilet, the battery—these are all great ideas. But where do they come from? What kind of environment breeds them? What sparks the flash of brilliance? How do we generate the groundbreaking ideas that push forward our lives, our society, our culture?
In a leaked climate report, the Intergovernmental Panel on Climate Change (IPCC) — a United Nations scientific body that makes definitive assessments on climate change — has determined with 95 percent certainty that humans are responsible for global warming.
The report also increased its estimate for sea level rise, as a result of the warming planet.
The final report is due to come out in September. A draft was leaked over the weekend.

The Centers for Disease Control and Prevention says 300,000 Americans are getting Lyme disease every year, and the toll is growing.
"It confirms what we've thought for a long time: This is a large problem," Dr. Paul Mead tells Shots. "The bottom line is that by defining how big the problem is we make it easier for everyone to figure out what kind of resources we have to use to address it."
Why do the smartest students often do poorly on standardized tests? Why did you tank that interview or miss that golf swing when you should have had it in the bag? Why do you mess up when it matters the most—and how can you perform your best instead?
Scientists have known for years that dolphins recognize each other by the sound of each animal's signature whistle. But it wasn't known for just how long dolphins could remember these whistle calls.
The individually specific whistle that each dolphin generates before its first birthday "for them functions like a name," says Jason Bruck, who studies animal behavior at the Institute for Mind and Biology at the University of Chicago.
One office worker says he enjoys sitting and he’s tired of the “superior moral attitude” from the standers around him.
Writer Ben Crair told Here & Nowhe accepts the medical studies showing that sitting at your desk is bad for your health. His objection to standing is based on “the pure satisfaction I get from sitting,” he said.
He argues there are other solutions to the health problem of sitting too long.
The Wave. Water waves. Not lazy surf lapping at your toes along the beach. Colossal, ship-swallowing rogue waves; scientists scrambling to understand the phenomenon; and extreme surfers seeking the ultimate challenge. Susan Casey’s account follows the exploits of boarders conquering suicidally large, 70- and 80-foot waves and the physicists trying to grapple with the destructive powers of 1,740-foot waves off the coast of Alaska and tsunamis in the Pacific. Casey is our guest.
According to Wyoming's Game and Fish Department, there has been a 70 percent decline in migratory elk calf production in Yellowstone since 1992. For years, researchers suspected predatory wolves were to blame. Now, a new study details a more complex set of circumstances that account for the low calf numbers.
If you want to think about the way our diminished interest in the humanities amounts to playing with fire, consider the present moment, which includes wind-driven deadly wildfires in Arizona and a tornado in Windsor and the recurrent suggestion that this is "the new normal."
The new normal is incredibly dangerous and getting worse. We have enormous amounts of scientific information that explains why some of this is happening, and what we should do to keep it from getting worse. But as a planet and a nation, we're not doing much. Why?
