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

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…

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…

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

More hype on Greenland's summer melt

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.…

Crack in the Earth: Greenland glacier loses ice island twice the size of Manhattan

It’s business as usual at the Petermann glacier, doing what a glacier does, calving ice into the sea. We reported on another chunk in 2010, four Manhattans in size. Borrowing…

'We don’t believe the ice cores can be interpreted purely as a signal of temperature'
