The world's oceans have warmed 50 percent faster over the last 40 years than previously thought due to climate change, Australian and US climate researchers reported Wednesday. Higher ocean temperatures expand the volume of water, contributing to a rise in sea levels that is submerging small island nations and threatening to wreak havoc in low-lying, densely populated delta regions around the globe. The study, published in the British journal Nature, adds to a growing scientific chorus of warnings about the pace and consequences rising oceans. It also serves as a corrective to a massive report issued last year by the Nobel-winning UN Intergovernmental Panel on Climate Change (IPCC), according to the authors. Rising sea levels are driven by two things: the thermal expansion of sea water, and additional water from melting sources of ice. Both processes are caused by global warming. The ice sheet that sits atop Greenland, for example, contains enough water to raise world ocean levels by seven metres (23 feet), which would bury sea-level cities from Dhaka to Shanghai. Trying to figure out how much each of these factors contributes to rising sea levels is critically important to understanding climate change, and forecasting future temperature rises, scientists say. But up to now, there has been a perplexing gap between the projections of computer-based climate models, and the observations of scientists gathering data from the oceans. The new study, led by Catia Domingues of the Centre for Australian Weather and Climate Research, is the first to reconcile the models with observed data. Using new techniques to assess ocean temperatures to a depth of 700 metres (2,300 feet) from 1961 to 2003, it shows that thermal warming contributed to a 0.53 millimetre-per-year rise in sea levels rather than the 0.32 mm rise reported by the IPCC. 1. Ultimately, the new study should help scientists to ____. A. lower water levels. B. better predict climate change. C. bury sea-level cities like Dhaka and Shanghai. 2. The rise in water levels is especially dangerous for small island nations and ____. A. low-lying urban areas. B. all coastal cities. C. people who live on the beach. 3. What happens when the ocean's temperature rises? A. It causes sea levels to rise. B. It causes sea levels to remain constant. C. It causes sea levels to decrease. 4. What was the main finding of the study? A. not enough is being done about global warming. B. ocean waters have warmed faster than scientists had previously thought. C. the warming of the world's oceans is not a threat. 5. The new study ____. A. shows that thermal warming contributed to a 0.32 millimeter-per-year rise in sea levels. B. did not reveal anything that scientists didn't already know. C. used new techniques to assess ocean temperatures. D. WRITING I. Rewrite the sentences, using perfect gerunds. 1.

One of the factors in global warming is carbon monoxide. The more carbon monoxide in the atmosphere, the less the atmosphere is able to clean itself. The result is a warming of the atmosphere, the so-called global warming, and possibly ozone damage. Earlier, it was found that carbon monoxide was concentrated in the Southern Hemisphere, and could be attributed to deforestation. Huge areas of forest and grasslands in South America and Africa have been burned, putting carbon monoxide into the atmosphere. Recently, however, the Southern Hemisphere has been found to be clean, while the Northern Hemisphere is more polluted than expected. The latest research was done during the northern winter. The high levels in the Northern Hemisphere could be because of this. In winter carbon monoxide is destroyed more slowly. There are also more fires burned in winter, and possibly industrial processes work harder. It could also reflect the ever-increasing number of cars on the roads. Optimists hope that the reason why the North has overtaken the South as the major area of carbon monoxide is that at last the burning has stopped, or at least slowed down. 1. Which of the following is the best title for the passage? A Global warming. B. Carbon monoxide in the atmosphere. C. The warming of the atmosphere. D. Ozone damage. 2. Which of the following is NOT a reason for carbon dioxide? A. Ozone damage. B. Burning of forest. C. Traffic. D. Industry. 3. According to the author which of the following is a reason why in winter there is more carbon-monoxide in the atmosphere? A. Fewer factories are working. B. There is a decrease in the amount of traffic on the roads. C. Central heating means there are fewer fires nowadays. D. Carbon monoxide is not absorbed so fast. 4. Why are the optimists happy? A. People are buying more cars. B. There is more carbon dioxide in the North. C. They are possibly burning fewer forests in the Southern Hemisphere. D. Industry must be doing better. 5. What is the attitude of the author towards the new findings? A. He is biased in favor of the South. B. He is neutral. C. He agrees with the optimists. D. He is worried about the North. VIII.
