26、Ò»¸ö×î¼ÑÑ¡Ïî¡£Climate Change: The Long Reach1. Earth is warming. Sea levels are rising. There's more carbon in the air, and Arctic ice ismelting faster than at any time in recorded history. Scientists who study the environment

27、 to bettergauge (ÆÀ¹À) Earth's future climate now argue that these changes may not reverse for a very longtime.2. People burn fossil fuels like coal and oil for energy. That burning releases carbon dioxide, acolorless gas. In the air, this gas traps heat at Earth¡¯s

28、 surface. And the more carbon dioxidereleased, the more the planet warms. If current consumption of fossil fuels doesn¡¯t slow, thelong-term climate impacts could last thousands of years ¡ª and be more severe than scientists hadbeen expecting. Climatologist Richard Zeebe of the U

29、niversity of Hawaii at Manoa offers thisconclusion in a new paper.3. Most climate-change studies look at what's going to happen in the next century or so. Duringthat time, changes in the planet's environment could nudge (Íƶ¯) global warming even higher.For example: Snow

30、and ice reflect sunlight back into space. But as these melt, sunlight can nowreach ¡ª and warm ¡ª the exposed ground. This extra heat raises the air temperature even more,causing even more snow to melt. This type of rapid exaggeration of impacts is called a ¡°fastfeedba

31、ck.¡±.4. Zeebe says it's important to look at fast feedbacks. However, he adds, they're limited. From aclimate change perspective. "This century is the most important time for the next fewgenerations,¡± he told Science News. ¡°But the world is not ending in

32、 2100.¡± For his new study,Zeebe now focuses on ¡°slow feedbacks¡±. While fast feedback events unfold over decades orcenturies, slow feedbacks can take thousands of years. Melting of continental ice sheets and themigration of plant life ¡ª as they relocate to

33、more comfortable areas ¡ª are two examples of slowfeedbacks.5. Zeebe gathered information from previously published studies investigating how suchprocesses played out over thousands of years during past dramatic changes in climate. Thenhe came up with a forecast for the future that account

34、s for both slow and fast feedbackprocesses. Climate forecasts that use only fast feedbacks predict a 4.5 degree Celsius (8.1degree Fahrenheit) change by the year 3000. But slow feedbacks added another 1.5 ¡ãC ¡ª fora 6¡ã total increase, Zeebe reports. He also found that

52、 The Mir Space StationThe Russian Mir Space Station, which came down in 2001 at last after 15 years of pioneeringthe concept of long-term human space flight, is remembered for its accomplishments in the humanspace flight history. It can be credited with many firsts in space.During Mir¡¯s l

53、ifetime, Russia spent about US $4.2 billion to build and maintain the station.The Soviet Union launched Mir, which was designed to last from three to five years, onFebruary 20, 1986, and housed 104 astronauts over 12 years and seven months, most of whomwere not Russian. In fact, it became the first

54、international space station by playing host to 62people from 11 countries. From 1995 through 1998, seven astronauts from the United States tookturns living on Mir for up to six months each. They were among the 37 Americans who visited thestation during nine stopovers by space shuttles.The more than

55、400 million the United States provided Russian for the visits not only kept Miroperating, but also gave the Americans and their partners in the international station projectvaluable experience in long-term flight and multinational operations.A debate continues over Mir¡¯s contributions to

56、science. During its existence, Mir was thelaboratory for 23,000 experiments and carried scientific equipment, estimated to be worth $80million, from many nations. Experiments on Mir are credited with a range of findings, from thefirst solid measurement of the ration of heavy helium atoms in space to

57、 how to grow wheat inspace. But for those favouring human space exploration, Mir showed that people could live andwork in space long enough for a trip to Mars. The longest single stay in space is the 437.7 daysthat Russian astronaut Valery Polyakov spent on Mir from 1994 to 1995. And Sergie Avdeyeva

58、ccumulated 747.6 days in space in three trips to the space station. The longest American stay wasthat of Shannon Lucid, who spent 188 days aboard Mir in 1996.Despite the many firsts Mir accomplished, 1997 was a bad year out of 15 for Mir. In 1997, anoxygen generator caught fire. Later, the main comp

59、uter system broke down, causing the station todrift several times and there were power failures.Most of these problems were repaired, with American help and suppliers, but Mir¡¯sreputation as a space station was ruined.Mir¡¯s setbacks are nothing, though, when we compare them wit

60、h its accomplishments. Mirwas a tremendous success, which will be remembered as a milestone in space exploration and thespace station that showed long-term human habitation in space was possible. But it¡¯s time to moveon to the next generation. The International Space Station being built w

66、; Eye-tracker Lets You Drag and Drop Files with a Glance£¨2014Ö°³ÆÓ¢ÓïÀí¹¤A¿¼ÊÔÕæÌâÖеÄÔĶÁÀí½â£©Bored of using a mouse?

67、 Soon you'll be able to change stuff on your computer screen¡ªandthen move it directly onto your smartphone or tablet ¨C with nothing more than a glance.A system called EyeDrop uses a head-mounted eye tracker that simultaneously records yourfield of view so it knows where you are

68、looking on the screen. Gazing at an object¡ªa photo, say ¨Cand then pressing a key, selects that object. It can then be moved from the screen to a tablet orsmartphone just by glancing at the second device, as long as the two are connected wirelessly."The beauty of using gaze to s

69、upport this is that our eyes naturally focus on content that wewant to acquire," says Jayson Turner, who developed the system with colleagues at LancasterUniversity, UK.Turner believes EyeDrop would be useful to transfer an interactive map or contactinformation from a public display to your sma

70、rtphone or for sharing photos.A button needs to be used to select the object you are looking at otherwise you end up withthe "Midas touch" (µãʯ³É½ð) effect, whereby everything you look at gets selected by your gaze,says Turner. "Imagine if your

71、 mouse clicked on everything it pointed at," he says.Christian Holz, a researcher in human-computer interaction at Yahoo Labs in Sunnyvale,California, says the system is a nice take on getting round this fundamental problem of usinggaze-tracking to interact. "EyeDrop solves this in a slick

72、 way by combining it with input on thetouch devices we carry with us most of the time anyway and using touch input as a clutchingmechanism," he says. "This now allows users to seamlessly interact across devices far and closein a very natural manner."While current eye-trackers are rath

73、er bulky, mainstream consumer devices are not too faraway. Swedish firm Tobii is developing gaze-tracking technology that can be installed in laptopsand tablets and is expected to be available to buy next year. And the Google Glass headset isexpected to include eye-tracking in the future.Turner says he has also looked at how content can be cut and pasted or drag-and-droppedusing a mix of gaze and taps on a touchscreen.
