There was more positive news in South East Asia, however, with government policies helping to reduce forest loss.Tropical rainforests store hundreds of billions of tonnes of carbon in soils and woody trunks. But this new global record raises further questions about their resilience on a warming planet.

Many researchers are concerned some forests, such as parts of the Amazon, may be approaching a "tipping point", beyond which they could fall into irreversible decline."The tipping point idea is, I think, increasingly the right one," said Prof Matthew Hansen, co-director of GLAD laboratory at the University of Maryland, which produces the data.Prof Hansen described the new results as "frightening", and warned of the possible "savannisation" of the rainforest, where old-growth tropical forests die back and permanently switch to savanna.

"It's still a theory, but I think that that's more and more plausible looking at the data.", made a similar warning of possible significant dieback of the Amazon if global warming exceeds the

This would not only threaten the vibrant array of wildlife living in these most biodiverse habitats, but would also have serious ramifications for the global climate.

Until recently, the Amazon had been doing humanity a favour, absorbing more planet-warming carbon dioxide (CO2) than it released.He went back to the US and did his master's at Johns Hopkins University, and now works at Chinese tech giant Baidu.

But despite the degree from a prestigious American university, Mr Chen does not feel he has an edge because of the stiff competition from graduates in China.What also has not helped is the suspicion around foreign graduates. Beijing has ramped up warnings of foreign spies, telling civilians to be on the lookout for suspicious figures.

In April, prominent Chinese businesswoman Dong Mingzhu told shareholders in a closed-door meeting that her company, home appliance maker Gree Electric, will "never" recruit Chinese people educated overseas "because among them are spies"."I don't know who is and who isn't," Ms Dong said, in comments that were leaked and went viral online.
