Global sea levels could rise by about 30cm during this century if current trends continue, a study warns.THAT IS TOTAL PREDICTED RISE FOR THE ENTIRE CENTURY. BIG DEAL! That's something to YAWN about!
Australian researchers found that sea levels rose by 19.5cm between 1870 and 2004, with accelerated rates in the final 50 years of that period. The research, published in the journal Geophysical Research Letters, used data from tide gauges around the world.
Over the entire period from 1870 the average rate of rise was 1.44mm per year.
Over the 20th Century it averaged 1.7mm per year; while the figure for the period since 1950 is 1.75mm per year. ... If the acceleration continues at the current rate, the scientists warn that sea levels could rise during this century by between 28 and 34cm.
