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.

Remembering names is an important social skill. Here are some ways to master it.

Recite and repeat in conversation.

When you hear a person’s name,repeat it. Immediately say it to yourself several times without moving your lips. You could also repeat the name in a way that does not sound forced or artificial.

Ask the other person to recite and repeat.

You can let other people help you remember their names. After you’ve been introduced to someone,ask that person to spell the name and pronounce it correctly for you. Most people will be pleased by the effort you’re making to learn their names.

Admit you don’t know.

Admitting that you can’t remember someone’s name can actually make people relaxed. Most of them will feel sympathy if you say. “I’m working to remember names better. Yours is right on the tip of my tongue. What is it again?”

Use associations.

Link each person you meet with one thing you find interesting or unusual. For example,you could make a mental note: "Vicki Cheng -- tall, black hair.” To reinforce you’re your associations, write them on a small card as soon as possible.

Limit the number of new names you learn at one time.

When meeting a group of people, concentrate on remembering just two or three names. Free yourself from remembering every one. Few of the people in mass introductions expect you to remember their names. Another way is to limit yourself to learning just first names. Last names can come later.

Go early.

Consider going early to conferences, parties and classes. Sometimes just a few people show up on time. That’s fewer names for you to remember. And as more people arrive, you can hear them being introduced to others-an automatic review for you.
