The gas revolution isn’t all roses 다운로드. People have legitimate worries about the environmental impacts of fracking—notably on air and water. There are also some worrying signs that fracking operations might emit lots of greenhouse gases—which, if true, would negate much (perhaps all) of the climate change benefits from a shift to gas 제인도 다운로드. My read of that literature is that those fears have been overblown and new estimates based on serious measurement will be more reassuring.
Only time will tell how this new ‘gas age’ affects the planet 다운로드.
Most people know the traditional banking model, if only from George Bailey in It’s A Wonderful Life다운로드.
In simplified form: A bank takes deposits from savers, and pays them a low interest rate. Then it lends that money out to borrowers at a higher interest rate 다운로드. The bank’s profits come from the difference between the rates.
The two most important ‘extra’ activities are charging fees and the outright investing of their own money. Here is how it breaks down:
$48 billion – interest from loans
$35 billion – fees
$11.5 billion – trading
A little less than half of the bank’s revenue comes from non-traditional banking activities (fees, trading) 다운로드. Not so bad, especially with trading accounting for so little. Remember, one of the root causes of the financial crisis was all the big banks exploding their trading 다운로드. When the market collapsed so did they, but were “too big to fail” and we had to bail them out.
Suffice it to say that banking with deposits and loans is very hard (George Bailey nearly went under), add in too much trading and banks become very unstable 다운로드.
This full-circle scene combines 817 images taken by the panoramic camera (Pancam) on NASA’s Mars Exploration Rover Opportunity 스틱맨 다운로드. It shows the terrain that surrounded the rover while it was stationary for four months of work during its most recent Martian winter.
Its release this week coincides with two milestones: Opportunity completing its 3,000th Martian day on July 2, and NASA continuing past 15 years of robotic presence at Mars 유튜브 영화 다운로드.
On Aug 다운로드. 5 or Aug. 6, depending on which part of the country you’re in, the Curiosity spacecraft careening toward Mars will hit the Red Planet’s atmosphere, deploy a supersonic parachute and either land safely on the planet’s surface or perish 다운로드. It’s dramatic stuff, and NASA has produced this Hollywood-style YouTube video, complete with animation and suspenseful music, to preview the landing, evoke that drama and put viewers on the edge of their seats 다운로드.
As engineers explain, it will take seven minutes for Curiosity to travel from the edge of Mars’ atmosphere to the surface, going from a speed of 13,000 mph to zero2010 엑셀 무료. “If any one thing doesn’t work just right, it’s game over,” engineer Tom Rivellini says.
Because Mars is so far away, it actually takes 14 minutes for the spacecraft’s signal to reach Earth 다운로드. So by the time we learn the spacecraft has hit the top of Mars’ atmosphere, Curiosity will have either have survived the landing or perished for a full seven minutes 패러렐 즈 무료 다운로드.
The time has come. We’re finally giving female surfers the love they deserve in a brand-new, all-girls magazine, SALTED. The mag, created by the editors of SURFER Magazine, features the best female surfers on the planet, trips to the most idyllic locales, profiles, interviews, history, fashion features, and more 다운로드. It’s is a much-overdue homage to women’s surfing, all made with the quality, authenticity, and top-notch imagery you’ve come to expect from SURFER 다운로드.
Hitting newsstands August 14, SALTED is nearly 100 pages of uninterrupted female surf content in an oversized, glossy format. Find it at your local surf shop or bookstore 다운로드. The digital version will also be available on the Apple Newsstand beginning August 6.
The official position of planet Earth at the moment is that we can’t raise the temperature more than two degrees Celsius.
Some context: So far, we’ve raised the average temperature of the planet just under 0.8 degrees Celsius, and that has caused far more damage than most scientists expected 다운로드. (A third of summer sea ice in the Arctic is gone, the oceans are 30 percent more acidic, and since warm air holds more water vapor than cold, the atmosphere over the oceans is a shocking five percent wetter, loading the dice for devastating floods.)
Scientists estimate that humans can pour roughly 565 more gigatons of carbon dioxide into the atmosphere by midcentury and still have some reasonable hope of staying below two degrees 다운로드.
We’re not getting any free lunch from the world’s economies, either. With only a single year’s lull in 2009 at the height of the financial crisis, we’ve continued to pour record amounts of carbon into the atmosphere, year after year 바둑 대국. In late May, the International Energy Agency published its latest figures – CO2 emissions last year rose to 31.6 gigatons, up 3.2 percent from the year before 다운로드.
America had a warm winter and converted more coal-fired power plants to natural gas, so its emissions fell slightly
China kept booming, so its carbon output (which recently surpassed the U.S.) rose 9.3 percent
Japanese shut down their fleet of nukes post-Fukushima, so their emissions edged up 2.4 percent 엑시트 1080p 다운로드.
In a surprise find, astronomers have discovered a planet possibly covered with oceans of magma “right around the corner.”
Thirty-three light years away, “we have a sub-Earth-sized planet that’s slightly larger than Mars and essentially right around the corner, at least on a cosmic scale,” said Kevin Stevenson, a planetary scientist now at the University of Chicago
UCF-1.01 is about 5,200 miles (8,400 kilometers) wide, making about a quarter the volume of Earth 스트림 다운로드. And with a year that lasts only 1.4 Earth days, the new planet’s orbit takes UCF-1.01 searingly close to its star.
“It could be a thousand degrees Fahrenheit [540 degrees Celsius] fobs. That may be hot enough to make an ocean of molten rock.”
Researchers using NASA’s Spitzer Space Telescope essentially stumbled upon the new planet while studying a hot, Neptune-size planet called GJ 436b 찬송가 무료 다운로드.
