![]() ![]() The ship was big, 395 feet long, and it offered five-course French cuisine complete with waiters, wine, cheese plates, and pastries. To answer their questions, the American scientists had chartered the R/V Marion Dufresne for 48 hours of round-the-clock coring work. One question the scientists were asking: How has climate change shaped the evolution of this estuary? Sediments, if you know how to read them, have a story to tell: they catch and hold the remnants of whatever washed into the Bay once upon a time, or blew into the Bay, or lived and died in these waters. “We were trying to learn more about the long-term history of the Chesapeake Bay,” says Debra Willard of the U.S Geological Service. The American scientists had questions about past climate changes and the sediments might hold answers–or at least clues. On board were a dozen American scientists, most of them geologists or geophysicists who were hoping to punch coring tubes down into the bottom of the Bay and bring up sediments buried there before the estuary formed. On June 2, 2003, a French vessel designed for deep-ocean research entered the Chesapeake Bay, an estuary noted for its shallow waters. Ice core indicators show that the Holocene, our current interglacial epoch, began some 11,000 years ago and brought a time of stable temperatures, interrupted by a cool-down 8,200 years ago and later by the Medieval Warm Period and the Little Ice Age. Why was the Pentagon suddenly worried about abrupt climate change? Because there was new evidence it had happened before. ![]() It was a speculative effort by defense strategists to dramatize all the security threats the country would face if the climate suddenly shifted. The report was never designed as a scientific prediction. Those implications included rising seas, flooded coastal cities, at least one drowned country, droughts, food shortages, failed states, and fortress states. The title of the Pentagon report was a mouthful: An Abrupt Climate Change Scenario and its Implications for United States National Security. IN OCTOBER 2003, A LITTLE-KNOWN THINK TANK in the Department of Defense quietly released a report warning that climate change could happen suddenly-so suddenly it could pose a major threat to our country's national security. Geological Survey, who analyzed sediment cores from the Chesapeake Bay and found evidence of abrupt climate change during the early evolution of the estuary. What is the number missing from the third target ? A).Thomas Cronin, a research geologist, collaborated with colleagues at the U.S. \( \Large 24 \bigtriangleup 4 \bigtriangleup 5 \bigtriangleup 4 \) A). Select the choice with the correct sequence of signs which when substituted makes the question as a correct equation. which are given as choices under each question. In the following question, \( \Large \bigtriangleup \) stands for any of the mathematical signs at different places. How far did the son meet his father from the starting point ? A). From here he went 100 metres to his north before meeting his father in a street. He went 20 metres before turning to his right again to look for his father at his uncle's place 30 metres from this point. He went 90 metres in the east before turning to his right. Find out the correct answer for the unsolved equation on the basis of the given equations. If SPARK is coded as TQBSL, what will be the code for FLAME ? A). which one of the following equations becomes correct ? A). After interchanging \( \Large \div \) and +, 12 and 18. Find the missing number from the given responses.
