If left unabated, some scientists say climate change could elevate sea levels (meaning more flooding, fewer beaches and less land) and alter weather patterns (hurting agriculture and producing more extreme weather events), among other repercussions.
Some of the most frightening forecasts in the report centre on the increasing pace of coastal erosion expected to accompany climate change, as sea levels continue to rise and low-lying shores become more vulnerable to storm surges.
Recognising that a number of climate models were predicting sea level rises of tens of centimetres by 2100, the scientist said some of the assumptions that underpinned the computer work and the global warming hypothesis in general would almost certainly need to be reviewed.
This warming is causing glaciers and ice shelves to melt, releasing large volumes of fresh water into the oceans which not only raises sea level, but also influences regional climate change.
Climate change models of Arctic sea ice cover in September, the month when ice is usually at its minimum, suggest an average loss of 2.5 percent of ice cover per decade from 1953 to 2003.
