CLASS 9th TO 12th Unseen passage In ENG.A few tips and tricks to solve with exercise Set-3
Unseen passage
Q.Read following passage carefully and answers that follows
1. Scientists are peering into the clouds near the top of the world, trying to solve a mystery and learn something new about global warming. The mystery is the droplets of water in the clouds. With the North Pole just 685 miles away, they should be frozen, yet most of them are in a liquid state. Therefore, scientists are trying to determine whether the clouds are one of the causes or effects of the Earth's warming atmosphere. "Much to our surprise, we found that the Arctic clouds have got plenty of super-cooled liquid water inside them. Liquid water has even been detected in clouds at temperatures as low as minus 30 degrees Celsius (minus 22° F)," said Taneil Uttal.
2. With NASA reporting that 2005 was the warmest year on record worldwide, the debate over global warming marches on, but not here. The American and Canadian scientists at the Eureka Weather Station in the northern Canadian territory of Nunavut, like the Inuit who see their native habitat thaw, are beyond questioning the existence of climate change.
3. Uttal, Drummond and other American and Canadian scientists recently visited Eureka, an outpost established jointly by Canada and the United States in 1947, now equipped with instruments that sound like sci-fi inventions-the ozone spectrophotometer, for instance, or the tropospheric lidar. A lidar, an amalgamation of 'light' and 'radar', uses laser light to detect atmospheric particles.
"For a couple of decades now, we have known that super-cooled liquid water droplets could exist in clouds," Uttal said. "But the prevalence of it in the Arctic clouds was not really known until these specialised sensors started operating in the Arctic about eight years ago." In Nunavut, the melting is keenly felt. "In the old days, we used to have 10 months of winter; now it's six," said Simon Awa, an Inuit leader. "Every year, we're getting winter later and later."
4. For these 155,000 people of Canada, Greenland, Russia and the United States, it means less time to hunt caribou, walrus and polar bear. The permafrost ground that is continually frozen for at least two years is thawing, imperilling polar bears and forcing other animals to migrate farther north.
"The majority of the world's population hasn't really felt the global warming," said Awa. "But right now in the Arctic and in Nunavut, we're really worried because it's already affecting us."
