Researchers in the United States say analysis of temperature records over more than 50 years indicates that the western Antarctic Ice Sheet is warming nearly twice as fast as previously thought. In a new study the researchers say they’ve also found the first evidence of warming during the southern hemisphere’s summer months, which they fear could contribute to a rise in sea levels.
美国研究者称过去50多年来对温度记录的分析表明,南极冰原西部正以比料想的两倍速度开始变暖。研究者在一份新研究中称,他们还发现南半球夏季月份变暖的首份证据,他们担心这将导致海平面上升。
Rebels in the Central African Republic have seized the city of Bambari, the third largest in the country. It’s the sixth town they have taken since launching their campaign earlier this month. The rebels want to overthrow President Francois Bozize, who they accuse of failing to honour peace deal. Our West Africa correspondent Thomas Fessy reports.
中非共和国叛军占领该国第三个城市班贝利,这是本月初发起军事行动以来占领的第6个城市。叛军希望推翻总统弗朗索瓦·博齐泽,他们指责总统未能遵守和平协议。
The coalition of rebel groups, which has advanced rapidly over the past ten days, is now in control of Bambari, a town at a key crossroads between diamond mining sites and routes to the east. Regional leaders backed a call for negotiations on Friday. Each side accuses the other of breaking the ceasefire. But observers say that the rebels may have decided to push forward in a show of force to put more pressure on the administration before sitting down for talks.
