（2013-11-20）Africa faces costs to adapt to the effects of climate change that will rise to $350 billion a year by the 2070s if governments fail to rein in runaway emissions, according to a report from the UN Environment Program.
The costs of adapting Africa's infrastructure to the rising seas and stronger storms caused by global warming will likely total $7 billion to $15 billion by 2020 and "rise rapidly" thereafter because of ever-higher temperatures, UNEP said today in a report released at UN climate talks in Warsaw.
Envoys in the Polish capital are trying to craft by 2015 a new agreement binding all nations to limit greenhouse gas emissions from 2020, with the ultimate goal of limiting the temperature rise since industrialization to 2 degrees Celsius.
Adaptation costs and losses may total as much as 4 percent of the continent's economic output by 2100 if the planet remains on a track to warm by 4 degrees Celsius, according to the report.
Without adaptation measures, damages would total 7 percent of gross domestic product, the report indicated.
