单选题El Nino is the term used for the period when sea surface temperatures are above normal off the South American coast along the equatorial Pacific, sometimes called the Earth's heartbeat, and is a dramatic but mysterious climate system that periodically rages across the Pacific. El Nino means "the little boy" or "the Christ child" in Spanish, and is so called because its warm current is felt along coastal Peru and Ecuador around Christmas. But the local warming is just part of an intricate set of changes in the ocean and atmosphere across the tropical Pacific, which covers a third of the Earth's circumference. Its intensity is such that it affects temperatures, storm tracks and rainfall around the world. Droughts in Africa and Australia, tropical storms in the Pacific, torrential rains along the Californian coast and lush greening of Peruvian deserts have all been ascribed to the whim of EI Nino. Until recently it has been returning about every three to five years. But recently it has become more frequent--for the first time on record it has returned for a fourth consecutive year--and at the same time a giant pool of unusually warm water has settled down in the middle of the Pacific and is showing no signs of moving. Climatologists don't yet know why, though some are saying these aberrations may signal a worldwide change in climate. The problem is that nobody really seems sure what causes the El Nin o to start up, and what makes some stronger than others. And this makes it particularly hard to explain why it has suddenly started behaving so differently. In the absence of EI Nino and its cold counterpart, La Nina, conditions in the tropical eastern Pacific are the opposite of those in the west. the east is cool and dry, while the west is hot and wet. In the east, it's the winds and currents that keep things cool. It works like this. Strong, steady winds, called trade winds, blowing west across the Pacific drag the surface water along with them. The varying influence of the Earth's rotation at different latitudes, known as the Coriolis effect, causes these surface winds and water to veer towards the poles, north in the northern hemisphere and south in the southern hemisphere. The surface water is replaced by colder water from deeper in the ocean in a process known as upwelling. The cold surface water in turn chills the air above it. This cold dense air cannot rise high enough for water vapor to condense into clouds. The dense air creates an area of high pressure so that the atmosphere over the equatorial eastern Pacific is essentially devoid of rainfall.

单选题As any diplomat from Britain, Austria or Turkey can tell you, handling the legacy of a vanished, far-flung empire is a tricky business. But for Georgia, the gap between old glory and present vulnerability is especially wide. Today's Georgia is diminished by war, buffeted by geopolitics and recovering from post-Soviet chaos. But 800 years ago the country was a mighty military, cultural and ecclesiastical force. Its greatest monarch, Queen Tamara, defeated many foes (including her first husband) and built fine monuments. In her time, Georgia also had a big stake in the Christian life of the Holy Land. From Jerusalem to the Balkans, Georgia's priests, artists and church-builders were active and respected. So too were its poets, like Shota Rustaveli, the national bard who dedicated an epic to his beloved queen. In between seeking western aid and coping with power cuts, modern Georgia has pledged to keep a wary eye on every place where churches, inscriptions and frescoes testify to its golden age. That includes Greece, Turkey, Bulgaria, Romania and above all, Israel. Last year, Georgians were enraged when a fresco of Rustaveli, in a Jerusalem church under the care of the Greek Orthodox Patriarchate, was defaced, then badly restored. This year, a better restoration was done, but Georgians now want a promise that in all future restoration their own experts can take part. They also want to stop the seepage of Georgian frescoes and icons, supposedly under the Patriarchate's care, on to the art market. Several times, Georgia has had to use its meagre resources to buy back pieces of the national heritage. The hope is that things will improve with the recent election of a new Jerusalem Patriarch, after his predecessor was ousted under a cloud of scandal. Georgia's ties with Israel are good, thanks to a thriving Georgian-Jewish community with happy memories of its homeland. Georgia also gets along with Greece, amid a fug of sentimentality over legends about the Argonauts that link the two nations. But can these warm, fuzzy feelings translate into better protection for an ancient culture? That will be a challenge for Geld Bezhuashvili, who succeeds Salome Zourabichvili, the French-born diplomat who was sacked, after a power struggle, as Georgian foreign minister on October 19th.
