Rising sea levels could cost the world $14 trillion a year by 2100:
Failure to meet the United Nations’ 2ºC warming limits will lead to sea level rise and dire global economic consequences, new research has warned.
Published today in Environmental Research Letters, a study led by the UK National Oceanographic Centre (NOC) found flooding from rising sea levels could cost $14 trillion worldwide annually by 2100, if the target of holding global temperatures below 2 ºC above pre-industrial levels is missed.
Antarctic ice loss has tripled in a decade. If that continues, we are in serious trouble:
Antarctica’s ice sheet is melting at a rapidly increasing rate, now pouring more than 180 billion tonnes of ice into the ocean annually and raising sea levels a half-millimetre every year, a team of 80 scientists reported Wednesday.
The melt rate has tripled in the past decade, the study concluded. If the acceleration continues, some of scientists’ worst fears about rising oceans could be realized, leaving low-lying cities and communities with less time to prepare than they had hoped.
The result also reinforces that nations have a short window — perhaps no more than a decade — to cut greenhouse-gas emissions if they hope to avert some of the worst consequences of climate change.
Harvard Scientist: Climate Change May Be Worse Than We Think:
“We’re likely to see 4 maybe even 6 degrees (Celsius) of (global) warming over the next 100 years,” says Schrag, “and it’s happening more than 100 times faster than climate change we’ve experienced in the past.” Schrag believes there might be even more to be concerned about, saying there might be additional factors worsening climate change that scientists have not anticipated.
Adding to his grim forecast, Schrag says reversing the trend will be neither easy nor quick. For one thing, more than half of the CO2 currently affecting climate change will remain in our atmosphere 1,000 years from now. “A silver-bullet solution is not around the corner. It will require innovative investments sustained for at least the next century,” he says.
