Africa faces climate adaptation costs in the range of $7 billion to $15 billion per year by 2020, and that figure could rise to around $350 billion annually by 2070 if global warming exceeds 2 degrees Celsius, a U.N. report said on Tuesday.

Even if the 2 degrees goal - agreed by nearly 200 governments in 2010 - were to be met, the cost of adapting to more extreme weather and longer-term climate shifts would still be around $35 billion per year by the 2040s and $200 billion per year by the 2070s, according to the U.N. Environment Programme (UNEP).

OSLO, Oct 3 (Reuters) - The world's oceans are under greater threat than previously believed from a "deadly trio" of global warming, declining oxygen levels and acidification, an international study said on Thursday.

The oceans have continued to warm, pushing many commercial fish stocks towards the poles and raising the risk of extinction for some marine species, despite a slower pace of temperature rises in the atmosphere this century, it said.
