sea level rise accelerates.
Scientists have recently observed major changes in these glaciers: several have broken up at the ocean end (the terminus), and many have doubled the speed at which they are retreating.2, 5 This has meant a major increase in the amount of ice and water they discharge into the ocean, contributing to
sea -
level rise, which threatens low - lying populations.2, 3,5
Accelerated melting also adds freshwater to the oceans, altering ecosystems and changing ocean circulation and regional weather patterns.7 (See Greenland ice sheet hotspot
for more information.)

for 1992 - 2011.
Obviously, no one disputes that
Sea Level has been
rising since the last Ice Age - very slowly; and certainly, if
