IPCC: human-induced climate change may cause significant sea level rise

The Intergovernmental Panel on Climate Change (IPCC) has warned that human-induced climate change could end up increasing sea levels across the world substantially.

According to Valerie Masson-Delmotte, co-chair of IPCC Working Group I, human activities and the resulting climate change have been causing major changes in the Greenland ice sheet and this is affecting the sea levels around the world with levels rising in recent decades. Sea-level rise is enhancing coastal submersion risks.

The scientist pointed out that warming of the air about the Greenland ice sheet has been strongly related to human influence on the climate system. She added that despite a greater global awareness of the effects of climate change, recent extreme weather events such as those which have been witnessed in the Arctic, France and Syria, can all be traced back to human influence.

“The drought in Syria from 2007 to 2010 was unusual in a multi-centennial context, and human influence was discerned in the two components of drought — lack of rainfall and increased temperatures,” she said.

“This occurs in a region where climate models project increasing water stress in a changing climate, due to a change in large-scale atmospheric circulation for the Mediterranean area.”

Meanwhile she added that recent flooding in France’s “bread basket area” came about as heavy rainfall in that region tends to occur in a warmer climate.

“Warmer seas and warmer air allow the atmosphere to transport more moisture, so that the same rare meteorological situation favouring heavy rainfall is associated with more intense rainfall in a warmer world,” the climate scientist said.

“This event in France had major impacts on crop yields in our bread basket area.”
