The Intergovernmental Panel on Climate Change, or IPCC, will meet on April 12 in Berlin to chart ways in which the world can curb the greenhouse gas emissions that scientists say are overheating the planet.
It is also trying to give estimates on what it would cost.
In the third report of a landmark climate assessment, the IPCC is expected to say that to keep warming in check, the world needs a major shift in investments from fossil fuels — the principal source of man-made carbon emissions — to renewable energy.
