Sea Level Rise by 2100
According to the studies of an international panel of scientists, human activity is the cause of most of the temperature increases in recent decades, and warns that sea levels could conceivably rise by more than 3 feet by 2100 if emissions continue at a runaway pace.
The findings of the scientists have been reported in a draft summary of the next big U.N. climate report. The report largely dismiss the belief that there has been a slowdown — often cited by those sceptical of climate change — in the pace of global warming, attributing it most likely to short-term factors.
The report emphasises that the basic facts about future climate change are now more firmly established than ever, justifying the rise in global concern. It also reiterates that the consequences of escalating emissions are likely to be profound.
A 3-foot rise would endanger many of the world’s great cities — among them are
1. London
2. Shanghai
3. Venice
4. Sydney
5. Miami
6. New Orleans and
7. New York.
“It is extremely likely that human influence on climate caused more than half of the observed increase in global average surface temperature from 1951 to 2010,” the draft report says. “There is high confidence that this has warmed the ocean, melted snow and ice, raised the global mean sea-level and changed some climate extremes in the second-half of the 20th century.”
At the worst condition, the report considers a scenario in which emissions, which have soared in recent years, continue at a runaway pace. Under those conditions, sea level could be expected to rise at least 21 inches by 2100 and might rise a bit more than 3 feet.
Hundreds of millions of people live near sea level, and either figure would represent a challenge for humanity, report says.
The draft document was prepared by the Intergovernmental Panel on Climate Change(IPCC), a large, international group of scientists appointed by the United Nations. The group does no original research, but instead periodically assesses and summarizes the published scientific literature on climate change.
