We need to take prompt action to keep global temperatures below the warming limit set by the United Nations. If we don’t, a new study claims that by 2100 the world could pay $14 trillion every year mitigating flooding impacts.
In 2010, the parties to the UN Framework Convention on Climate Change determined that it will be necessary to keep global average warming to below 2°C, or 3.6°F, above pre-industrial levels. And the consequences of failing to meet these goals are likely to be significant.
When global temperatures increase, sea levels rise too. That’s due to the melting of glaciers and ice sheets, as well as thermal ocean water expansion. More than 600 million people live in low-elevation coastal areas, defined as being less than 10 meters above sea level.
“These extreme sea levels will have a negative effect on the economies of developing coastal nations, and the habitability of low-lying coastlines,” Dr. Svetlana Jevrejeva of the UK National Oceanographic Centre, explained in a statement.
