by the end of this century and 13 to 20 feet in coming centuries, scientists are reporting today.
It notes that: 80 % of carbon dioxide emissions come from only 19 countries; the amount of carbon dioxide per US$ 1 GDP has dropped
by 23 % since 1992, indicating some decoupling of economic growth from resource use; nearly all mountain glaciers
around the
world are retreating and getting thinner; and
sea levels have been rising at an average rate of about 2.5 mm per year since 1992.
Your «Oceans» image shows raw tidal gauge data for certain cities

The glaciers of West Antarctica are already responsible for the majority of the Antarctic continent's contribution to global
sea level rise, and if these glaciers were to completely collapse,
sea levels could rise
by at least four feet, potentially inundating coastal cities
around the
world.
This could raise average global
sea level by up to 15 feet, inundating highly populated coastal areas
around the

The new study, the culmination of a decade of work
by three teams of far - flung scientists, has charted what they called an «acceleration» in

around the
world and the rise will be fairly gradual in any case and coastal communities will have time to mitigate its effect.
The authors observe that wide variations in rates of tectonic uplift and subsidence in different locations

seas insist on not getting acidic, the rainforest is still
around, islands have not sunk under the
sea, the ozone holes haven't got bigger, the
world hasn't entered a new ice age, acid rain appears to have fallen somewhere that can't quite be located, the Gulf Stream hasn't stopped, extreme weather events have been embarrassingly sparse in recent years and guess what?
