Hansen falsified: His extreme sea level rise projections are drowning in hubris

After yesterday’s tongue-in-cheek mention of Obama’s healing the planet (and sea level rise with it) here’s the real lowdown on the current knowledge. It seems that all the science that Hansen uses to base his 5-6 meter sea level rise has now been overturned by more recent scientific findings.  Basically, there is no longer any…

New research projects mitigation of sea level rise

Recent snowfall anomalies in Dronning Maud Land, East Antarctica Enhanced snowfall on the East Antarctic ice sheet is projected to significantly mitigate 21st century global sea level rise. In recent years (2009 and 2011), regionally extreme snowfall anomalies in Dronning Maud Land, in the Atlantic sector of East Antarctica, have been observed. It has been…

NCAR says targeting specific pollutants would slow SLR

From the  National Center for Atmospheric Research/University Corporation for Atmospheric Research I can see the EPA jumping all over this one. Black carbon is likely a contributor, as it changes the albedo of ice sheets and one that is much easier to manage. Problem is, the USA isn’t much of a black carbon emitter any…

Uncertainty be damned, let's make ice and sea level projections anyway

‘A better path’ toward projecting, planning for rising seas on a warmer Earth From Princeton University, by Morgan Kelly, Office of Communications More useful projections of sea level are possible despite substantial uncertainty about the future behavior of massive ice sheets, according to Princeton University researchers. In two recent papers in the journals Nature Climate…

Modeling sea level rise is an 'uneven' proposition

From the British Antarctic Survey New projections of ‘uneven’ global sea-level rise Reporting in the journal Geophysical Research Letters researchers have looked ahead to the year 2100 to show how ice loss will continue to add to rising sea levels Sophisticated computer modelling has shown how sea-level rise over the coming century could affect some…

Paleo sea level and CO2

From the National Oceanography Centre, Southampton (UK) New study documents the natural relationship between CO2 concentrations and sea level By comparing reconstructions of atmospheric CO2 concentrations and sea level over the past 40 million years, researchers based at the National Oceanography Centre, Southampton have found that greenhouse gas concentrations similar to the present (almost 400…
