The Intergovernmental Panel on Climate Change (IPCC) presented the special report on the Ocean and Cryosphere in a Changing Climate Context.
Key Findings
The global mean sea level had risen by 16 cm between 1902 and 2015. The rate of increase had doubled in the last one decade.
The sea levels were rising because of thermal expansion of ocean waters due to rising temperatures as well as due to melting of glaciers and polar ice.
Examples
Greenland ice sheet – Between 2006 and 2015 lost ice-mass at an average rate of 278 billion tonnes every year.
Antarctic ice sheet - lost a mass of 155 billion tonnes every year between 2006 and 2015.
