Marcott et al claim of ‘unprecedented’ warming compared to GISP ice core data

Posted on March 8, 2013 by

The very first sentence of the Marcott et al (which is getting heavy press) abstract says: Surface temperature reconstructions of the past 1500 years suggest that recent warming is unprecedented in that time. Okay, let’s have a look at the … Continue reading →

Modeling sea level rise is an ‘uneven’ proposition

Posted on February 21, 2013 by

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 →

Chris Mooney’s Chartsmanship in the Service of Alarmism

Posted on February 7, 2013 by

Guest Post by Willis Eschenbach I came across this beautiful example of chartsmanship today in a Chris Mooney post of raw, pure, visceral alarmism, it’s a gem. It’s from the Mother Jones website and comes with the lovely headline “Humans … Continue reading →

First complete ice core record of last interglacial period shows the climate of Greenland to be significantly warmer than today

Posted on January 24, 2013 by

Study: ‘ Greenland ice sheet is not as sensitive to temperature increases and to ice melting and running out to sea in warm climate periods ‘. From the University of Copenhagen Greenland ice cores reveal warm climate of the past … Continue reading →

Glacially modeled snow job

Posted on December 12, 2012 by

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 →

Why ice loss and sea level measurements via satellite and the new Shepherd et al paper are highly uncertain at the moment

Posted on December 3, 2012 by

There’s a paper (Shepherd et al) on ice loss and sea level rise that has been making the rounds in media (such as this article in Science Recorder, claiming it validates global warming) that is causing some stir, mainly because … Continue reading →

More hype on Greenland’s summer melt

Posted on August 15, 2012 by

You may recall the bogus claim of “97% of Greenland Ice melted”, that was dialed back (REP’s last story on WUWT). Now there’s more of the same sort of stuff. See this PR, and note my bold for the money … Continue reading →
