Planet Earth – the most complex thing in the universe. Warmed and cooled by natural trends, heated by greenhouse gases from humans. Scientists are striving to work it all out. In the Pacific for instance, the warming El Nino current is likely to bring floods where there is normally drought and drought where there's normally rain. Corals were bleached by the last big El Nino in 1998. The new El Nino will heat the world; so will a separate climate event in the Pacific. But these will be offset somewhat by a cooling event in the Atlantic. Three big shifts at once.

地球是宇宙中最为复杂的物体。它随自然气候变换，冷热交替；它也因人类活动排放的温室气体而变暖。科学家们企图知晓地球万物的所有规律。比如，太平洋厄尔尼诺暖流会使往常干旱地区洪水泛滥或让雨水丰润地区迎来干旱。1998年厄尔尼诺现象使珊瑚颜色白化。目前新一轮厄尔尼诺现象将使全球气温升高；太平洋中的另一股气候变化活动也会引发相同结果。不过大西洋降温会部分抵消温室气体的增暖作用使全球增暖趋势停滞。三个重要气候变化活动同时发生。

You're watching what doctors describe as one of the most revolutionary advances in the history of surgery. Here at the Royal Marsden Hospital in London consultant surgeon Declan Cahill seems to sit within the robot – a blend of man and machine. He remains, though, very much in control. It's a tool just like his scalpel or forceps, albeit far more sophisticated.

你正在看到的画面被医生们描述为手术史上“最具革命性的进步”。在伦敦皇家马斯登医院，外科顾问医生戴克澜·卡希尔（Declan Cahill）坐在机器人身体里 – 人机合二为一。尽管如此，手术还是完全由卡希尔医生来掌控。这台机器虽然看起来无比精密，但它其实就是一个像手术刀或手术钳的工具用来协助医生完成手术。

These are embaixadores da alegria – or happy ambassadors – made up of dancers of all disabilities. They're rehearsing for the 'Paralympics – one year to go' celebrations. Every year they perform at the Rio Carnival. But it wasn't until 2013 that they were allowed to parade with everyone else.
