Scientists meet in Japan after grim climate forecast

YOKOHAMA: International scientists gathered near Tokyo on Tuesday for a week-long meeting centred on a grim climate change report that warned of floods and drought that could stoke conflicts and wreak havoc on the global economy. 

A draft of their document, seen by AFP, is part of a massive overview by the Intergovernmental Panel on Climate Change (IPCC), likely to shape policies and climate talks for years to come. 

Scientists and government representatives are meeting in Yokohama, south of Tokyo, to exchange ideas and release a full report at the end of the conference on March 31. 

"We have a lot clearer picture of impacts and their consequences ... including the implications for security," said Chris Field of the United States' Carnegie Institution, who headed the probe. 

The work comes six months after the first volume in the long-awaited Fifth Assessment Report declared scientists were more certain than ever that humans caused global warming. 

Rising greenhouse-gas emissions will "significantly" boost the risk of floods, with Europe and Asia particularly exposed, the draft says. 

Temperature increase was also leading to the decline of renewable water resources, while the rising sea level was seen to displace "hundreds of millions" of coastal dwellers by 2100, according to the draft report. 

Average yields of wheat, rice and corn were seen to fall, while demand for crops will likely rise sharply due to expanding population. 

Poverty, migration and hunger are invisible drivers of turbulence and war, as they sharpen competition for dwindling resources, the report warns. 

By reducing carbon emissions "over the next few decades", the world can stave off many of the worst climate consequences by century's end, says the report. 

The panel has issued four previous "assessment reports" in its quarter-century history. 

The Yokohama volume goes further than its predecessors in forecasting regional impacts in greater detail and emphasizing the risk of conflict and rising seas. 

At the opening of the meeting, IPCC chairman Rajendra Kumar Pachauri said it would be of "enormous value". 

"This working group report will now enhance our understanding of issues related to impacts, vulnerability, and adaptation in the field of of climate change. 

"Of particular significance is detailed assessment of regional aspects which will give us much clearer understanding of impacts in the past, and those projected for the future in different regions," he said. 

The IPCC's last big report in 2007 helped unleash political momentum leading to the 2009 UN climate summit in Copenhagen. But its reputation was dented by several mistakes, seized upon by climate sceptics as proof of bias. 

Hosts Japan said the country's innovations could play an important role in mitigating the damaging effects of climate change. 

Environment minister Nobuteru Ishihara said Tokyo was eager to showcase its energy-efficient technology and environmental knowhow. 

"Japan is committed to exercising its leadership in negotiations for a new international framework for 2020 and beyond," he said.
