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…

Glacially modeled snow job

From the Potsdam Institute for Climate Impact Research (PIK)  Alarmism, I think maybe they are a bit unclear on the concept of how glaciers work. As snowfall varies with the seasons, the flow of ice speeds up and slows down. Besides, it isn’t real data, but just another modeling scenario tweaked for a particular outcome.…

Antarctic ice – more accurate estimates

Guest post by Verity Jones @ Digging In The Clay Cracking ice shelves make headlines, but ice loss estimates that are revised downwards don’t.  While there is great hand wringing over coastal ice loss in Greenland and the West Antarctic Peninsula, East Antarctica has more than eight times the ice mass of either. Last week’s…

Why I'm not worried about Greenland's icecap right now

There’s some blogospheric carping about his statement in the JPL press release below regarding Greenland’s ice sheets:“… their cumulative loss could raise sea level by 15 centimeters (5.9 inches) by 2050.” Well sure, it could be, but as this recent surprise study from GISS’s neighbors at Columbia illustrates, even though we’ve had the GRACE (Gravity…
