New re­search pre­dicts that sea lev­els might rise faster than any­one thought.

HWM (Malaysia) - - IMPACT - Alv­inSoon changes slowly and then all at once. What this means is that we might see the sub­mer­gence of low-ly­ing costal ar­eas like Bangladesh and the Nether­lands, and the ap­pear­ance of more su­per­storms like Hur­ri­cane Sandy, all within our life­times. Can

by A study*, pub­lished by James Hansen (a for­mer NASA cli­ma­tol­o­gist and the pioneer in cli­mate science) and 18 other co-au­thors has just passed for­mal peer re­view, after deep in­spec­tion by the sci­en­tific com­mu­nity.

This par­tic­u­lar study was so rig­or­ously in­ves­ti­gated be­cause it con­tains a star­tlingly rev­e­la­tion: Due to a feed­back cy­cle between the oceans and the ice sheets in Antarc­tica and Green­land, sea lev­els might rise two to five me­ters by the end of this cen­tury, which is five to 10 times faster than pre­vi­ous es­ti­mates.

The dif­fer­ence in es­ti­mates re­sults from Hansen and his as­so­ciates tak­ing into ac­count non-lin­ear rates of change on the cli­mate; in essence, the cli­mate sys­tem doesn’t change step by step, but *Ice melt, sea level rise and su­per­storms: ev­i­dence from pa­le­o­cli­mate data, cli­mate mod­el­ing, and mod­ern ob­ser­va­tions that 2 °C global warm­ing could be dan­ger­ous
