3 . I. M. Pei, whose modern designs and high-profile projects made him one of the best-known and most prolific architects of the 20th century, has died. He was 102. A spokesman for Pei’s New York architecture firm confirmed his death to the Associated Press. Pei, whose designs included a controversial renovation of Paris’ Louvre Museum and the Rock and Roll Hall of Fame in Cleveland, died overnight, his son Chien Chung Pei told The New York Times.

Ieoh Ming Pei, the son of an outstanding banker in China, left his homeland in 1935, moving to the US and studying architecture at the Massachusetts Institute of Technology and Harvard. After teaching and working for the US government, he went to work for a New York developer in 1948 and started his own firm in 1955.

The museums, municipal buildings, hotels, schools and other structures that Pei built around the world showed precision geometry (几何学) and an abstract quality with much respect for light. They were composed of stone, steel and glass and, as with the Louvre, Pei often worked glass pyramids into his projects.

The Louvre, parts of which date to the 12th century, proved to be Pei’s most controversial work, starting with the fact that he was not French. After being chosen for the job by the then president, François Mitterrand, surrounded by much secrecy, Pei began by making a four-month study of the museum and French history. He created a futuristic (未来主义的) 70ft-tall steel-framed, glass-walled pyramid as a grand entrance for the museum with three smaller pyramids nearby. It was a striking contrast to the existing Louvre structures in classic French style and was violently criticized by many French.

Pei said the Louvre was undoubtedly the most difficult job of his career. He said he had wanted to create a modern space that did not detract from the traditional part of the museum. “Contemporary architects tend to impose modernity on something,” he said in a New York Times interview in 2008. “There is a certain concern for history but it’s not very deep. I understand that time has changed, we have evolved. But I don’t want to forget the beginning. A lasting architecture has to have roots.”

When Pei won the international Pritzker Architecture Prize in 1983, he used the $100,000 award to start a programme for a spiring Chinese architects to study in the US. Even though he formally retired from his firm in 1990, Pei was still taking on projects in his late 80s, such as museums in Luxembourg, Qatar and his ancestral home of Suzhou.

4 . By the end of the century, if not sooner, the world’s oceans will be bluer and greener thanks to a warming climate, according to a new study.

At the heart of the phenomenon lie tiny marine microorganisms(海洋微生物) called phytoplankton. Because of the way light reflects off the organisms, these phytoplankton create colourful patterns at the ocean surface. Ocean colour varies from green to blue, depending on the type and concentration of phytoplankton. Climate change will fuel the growth of phytoplankton in some areas, while reducing it in other spots, leading to changes in the ocean’s appearance.

Phytoplankton live at the ocean surface, where they pull carbon dioxide(二氧化碳) into the ocean while giving off oxygen. When these organisms die, they bury carbon in the deep ocean, an important process that helps to regulate the global climate. But phytoplankton are vulnerable to the ocean’s warming trend. Warming changes key characteristics of the ocean and can affect phytoplankton growth, since they need not only sunlight and carbon dioxide to grow, but also nutrients.

Stephanie Dutkiewicz, a scientist in MIT’s Center for Global Change Science, built a climate model that projects changes to the oceans throughout the century. In a world that warms up by 3℃, it found that multiple changes to the colour of the oceans would occur. The model projects that currently blue areas with little phytoplankton could become even bluer. But in some waters, such as those of the Arctic, a warming will make conditions riper for phytoplankton, and these areas will turn greener. “Not only are the quantities of phytoplankton in the ocean changing. ” she said, “but the type of phytoplankton is changing.”

And why does that matter? Phytoplankton are the base of the food web. If certain kinds begin to disappear from the ocean, Dutkiewicz said, “it will change the type of fish that will be able to survive.” Those kinds of changes could affect the food chain.

Whatever colour changes the ocean experiences in the coming decades will probably be too gradual and unnoticeable, but they could mean significant changes. “It’ll be a while before we can statistically show that the changes are happening because of climate change,” Dutkiewicz said, “but the change in the colour of the ocean will be one of the early warning signals that we really have changed our planet.”
