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 on 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 great damage 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 of 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(热)expansion of sea water, and additional water from melting sources of ice. Both processes are caused by global warming. The ice sheet that sits at the top of 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 confusing 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(与…一致)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.

Comprehensive lifestyle changes including a better diet and more exercise can lead not only to a better physique, but also to swift and dramatic changes at the genetic level, U.S. researchers said on Monday. In a small study, the researchers tracked 30 men with low-risk prostate cancer(前列腺癌)who decided against conventional medical treatment such as surgery and radiation or hormone therapy.

The men underwent three months of major lifestyle changes, including eating a diet rich in fruits, vegetables, whole grains, legumes and soy products, moderate exercise such as walking for half an hour a day, and an hour of daily stress management methods such as meditation(冥想). As expected, they lost weight, lowered their blood pressure and saw other health improvements. But the researchers found more profound changes when they compared prostate biopsies taken before and after the lifestyle changes. After the three months, the men had changes in activity in about 500 genes -- including 48 that were turned on and 453 genes that were turned off. The activity of disease-preventing genes increased while a number of disease-promoting genes, including those involved in prostate cancer and breast cancer, shut down, according to the study published in the journal Proceedings of the National Academy of Sciences.

The research was led by Dr. Dean Ornish, head of the Preventive Medicine Research Institute in Sausalito, California, and a well-known author advocating lifestyle changes to improve health. "It's an exciting finding because so often people say, 'Oh, it's all in my genes, what can I do?' Well, it turns out you may be able to do a lot," Ornish, who is also connected with the University of California, San Francisco, said in a telephone interview. "'In just three months, I can change hundreds of my genes simply by changing what I eat and how I live'. That's pretty exciting," Ornish said. "The implications of our study are not limited to men with prostate cancer."
