Human influence likely dominant cause of global warming, say climate expertsListen /
Leading climate experts have singled out human influence as the most likely dominant cause of global warming.
A report by the Intergovernmental Panel on Climate Change (IPCC) says global warming is unequivocal, adding that global temperatures have risen successively over the past three decades.
The panel says its assessment of scientific evidence finds that the atmosphere and the ocean have warmed, the amount of snow and ice has diminished, sea level has risen and concentrations of greenhouse gasses have increased.
The panel says global surface temperatures are likely to increase by between 1.5 and 2.0 degrees centigrade by the end of the century, the consequence of which may be increased frequency and duration of heat waves, more rain in wet regions and less rain in the dry regions.
It further adds that the sea level will continue to rise at a faster rate than that experienced over the past 40 years as the oceans get warmer and glaciers and ice sheets reduce.
The panel says limiting climate change will require substantial and sustained reductions of greenhouse gas emissions.
