Dueling press releases on ice melt – one says ‘uncertainty is large’ the other quantifies a number

Once again, it looks like claims of ‘consensus’ are overblown. In our previous news item we have this: …ice sheets are the largest potential source of future sea level rise – and they also possess the largest uncertainty over their … Continue reading

New study: Antarctic and Greenland ice sheet melt may be natural event, no consensus on cause

Ice sheets are the largest potential source of future sea level rise – and they also possess the largest uncertainty over their future behaviour From the University of Bristol Continuous satellite monitoring of ice sheets needed to better predict sea-level … Continue reading

Good news: World’s biggest ice sheets likely more stable than previously believed – upsets previous estimates of melting and sea level

Researchers show that high ancient shorelines do not necessarily reflect ice sheet collapse millions of years ago From the Canadian Institute for Advanced Research: For decades, scientists have used ancient shorelines to predict the stability of today’s largest ice sheets … Continue reading

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 … Continue reading

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 … Continue reading

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. … Continue reading

Antarctic weight loss seems to be in the eye of the beholder

From Newcastle University New understanding of Antarctic’s weight-loss New data which more accurately measures the rate of ice-melt could help us better understand how Antarctica is changing in the light of global warming. The rate of global sea level change … Continue reading

ICESAT Data Shows Mass Gains of the Antarctic Ice Sheet Exceed Losses

The results of ICEsat measurements are in for Antarctica, and it seems those claims of ice mass loss in Antarctica have melted now that a continent wide tally has been made. This was presented in the SCAR ISMASS Workshop in … Continue reading

NASA: Warm Ocean Currents Cause Majority of Ice Loss from Antarctica

Breaking news from NASA and the ICEsat team, that’s their headline, not mine. This really makes all the hype over the now discredited Steig et al. paper, which attempted to establish an air temperature warming trend as one of the … Continue reading

New paper: A high-resolution surface mass balance map of Antarctica shows “no significant trend in the 1979–2010 ice sheet”

Uh, oh. Another talking point bites the dust. Leif Svalgaard writes in to tell me of a significant new paper. While Gore, Hansen, Branson, and a gaggle of hangers on just finished a publicity stunt tour of Antarctica to tell … Continue reading

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 … Continue reading

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 … Continue reading

Antarctic ice models “not correct”, sea level rise “complicated”

There’s some surprising reaction to the press release we covered on WUWT recently. Here’s some excerpts:
