…the estimates currently differ by almost five meters (16.5 feet).
The United Nations’ forecast of how quickly global sea levels will rise this century is vital in determining how much money might be needed to combat the phenomenon. But predictions by researchers vary wildly, and the attempt to find consensus has become fractious.
It is a number which will ultimately establish how billions in taxpayer money will be spent — and it is one which is the subject of heated debate, both among politicians and scientists.
When the next report from the United Nations Intergovernmental Panel on Climate Change (IPCC) is issued in two years, it will include a forecast for how high the world’s oceans might rise by 2100. With 146 million people in the world currently living less than one meter above sea level, the forecast will be vital in determining how much money governments must spend on measures to protect people from the rising waters and to resettle those in the most acute danger.
Eighteen scientists from 10 countries are involved in the task, and their first step is to determine which of the myriad studies relating toon ocean levels to consider. In the end, they are to establish a possible range, with the maximum being the most decisive — and most — number. Even more challenging, the estimates currently differ by almost five meters (16.5 feet).
