3月10日當天，科學會議海平面上升議程的主講人、澳洲天氣和氣候研究中心的區奇博士(Dr. John Church)告訴與會者，從最近期的衛星和地面研究顯示，從1993之後，海平面將會持續以每年0.03公分的速度上升，上升速度遠超過20世紀的平均值。
About 600 million people, or nearly 10 percent of the world's population, live in low-lying areas at risk of flooding as sea levels rise due to climate change, according to research presented today at the International Scientific Congress on Climate Change in Copenhagen.
Even in the lower ranges of current predictions, it looks increasingly likely that sea level rise will be at least 50 cm (19.6 inches) by 2100, scientists told the Congress, and the upper range of sea level rise could be at least one meter (39 inches) by the end of this century
This means that if emissions of greenhouse gases are not reduced quickly and substantially, even in the best case scenario rising seas may inundate low lying coastal areas housing about one in every 10 people on the planet.
Organized by International Alliance of Research Universities, the three-day meeting opened today with more than 2,000 participants. The congress has received almost 1,600 scientific contributions from more than 70 countries, making it one of the world's largest ever interdisciplinary conferences on climate change.
The preliminary conclusions from the congress will be presented Thursday at the closing session and will be developed in a synthesis report to be published in June. The Danish government will give the synthesis report to all participants at the UN Climate Change Conference here in December. At that meeting, governments are expected to finalize a new global climate agreement that will pick up where the Kyoto Protocol leaves off in 2012.
Today, lead speaker in the sea level session, Dr. John Church of the Centre for Australian Weather and Climate Research in Hobart, Tasmania told participants, "The most recent satellite and ground based observations show that sea level rise is continuing to rise at three millimeters per year or more since 1993, a rate well above the 20th century average.
An earlier study led by Church shows that even a modest sea level rise of 50 centimeters will increase the number of coastal flooding events. The last assessment report from the Intergovernmental Panel on Climate Change from 2007 projected a sea level rise of 18 to 59 centimeters (7 to 23 inches). But the report stated that not all factors contributing to sea level rise could be calculated at that time.
The uncertainty was centered on how ice sheets react to the effects of a warmer climate and how they interact with the oceans, explained Eric Rignot, professor of earth system science at the University of California Irvine and a senior research scientist at NASA's Jet Propulsion Laboratory in Pasadena.
"As a result of the acceleration of outlet glaciers over large regions, the ice sheets in Greenland and Antarctica are already contributing more and faster to sea level rise than anticipated," said Rignot. "If this trend continues, we are likely to witness sea level rise one meter or more by year 2100."
