Big climate changes in the last million years might have come from something very small dust from outer space.
Earth changes between ice ages and warm periods in a(n) (41)Cthat includes several cycles,including a (42)H one that lasts 100,000years.Scientists (43)Asuggested this cycle might be due to changes in the inflow of cosmic(宇宙) dust.
The idea is that Earth (44)Eabove and below the imaginary planet that runs through the sun and Jupiter(木星),completing a cycle every 100,000years.So maybe it encounters (45)Gvarying amounts of dust during each cycle that produce the climate trend.
Now there is some (46)J,from ancient cosmic dust recovered in ocean-floor drilling near the Azores islands west of Portugal.The large quantity of the dust rises and falls with a wonderful 100,000year cycle during the period analyzed,253,000years to 458,000years ago.Periods of more dust are related to(47)F climates.
But that is a long way from showing that the dust (48)Bclimate.Some scientists argue that it is not clear how cosmic dust would make the climate warmer while dust from volcanoes is known to make it cooler.They say the cosmic dust is so thin that it is hard to see how it could have any climate(49)I.
Nevertheless,the new study shows scientists have to take the cosmic dust idea seriously.

Like many other young people,Lin Chi-ying (Vicky) and Chiang Chiu-ping (Pinky) dreamed of traveling the world.What makes them special is that they actually did it; what's more,they did it on bicycles.
At 18,Vicky read the famous Cycling Diary of Hu Rong-hua and was(41)H to take a bike tour of southern China by herself.In 1991,while riding along the island's east coast,she met a Japanese (42)F,who invited her to join him on a world cycling tour.
In July 1998,they began their trip in Alaska.Vicky soon realized,however,that their travel philosophies were quite different.Her partner seemed intent on testing his endurance,while she preferred (43)C the fantastic scenery and meeting the locals.They parted after a month.Vicky cycled alone through the Rocky Mountains down to the western United States.By this time,her (44)E efforts to persuade her college friend,Pinky,to join her had succeeded.
Once,in California,Vicky and Pinky were unable to find any cheap (45)B,so they camped in a park.They were woken up by (46)D police officers,who told them camping there was illegal.In cities,they would (47)J through colleges and libraries,"in need of air-conditioning,"Pinky joked.
Vicky and Pinky praise friends back in China who supported them (48)G,as well as people who assisted them along the way.They have fond (49)I of the wonderful friendliness of the people in a Turkish village,where Vicky and Pinky farmed,cooked,and danced with the locals.
