Study: Greenland Ice Sheet was smaller 3000-5000 years ago than today

From the University of Buffalo Clues in the Arctic fossil record suggest that 3-5,000 years ago, the ice sheet was the smallest it has been in the past 10,000 years…

NASA to do summer aerial melt watch for Greenland

NASA Begins Airborne Campaign to Map Greenland Ice Sheet Summer Melt For the first time, a NASA airborne campaign will measure changes in the height of the Greenland Ice Sheet…

The WUWT Hot Sheet for September 12th, 2013

Climate models wildly overestimated global warming, study finds Can you rely on the weather forecast? Maybe not, at least when it comes to global warming predictions over short time periods.…

When it comes to new high temperature records, 'shoot first, ask questions later'

Readers may recall my investigation over the weekend of an announcement by the Danish Meteorological Institute (DMI) about a new all-time high temperature record set in Greenland that was subsequently…

Surprise: Greenland ice gets a melt assist from Earth's hot mantle below

From the Helmholtz Association Greenland ice is melting — also from below Heat flow from the mantle contributes to the ice melt The Greenland ice sheet is melting from below,…

How not to measure temperature – Part 94 – Maniitsoq, Greenland all time high temperature rescinded?

UPDATE: 7/12/13 1045 PDT DMI concedes the record may not be valid, see here I’ve been working on this one for a week, and I finally confirmed my hunch about…

Oh, what a difference a year makes in Greenland melting

ARCTIC SUMMER SNOWSTORM By Joseph D’Aleo CCM Remember a year ago when few days of July ‘warmth’ with strong blocking over Greenland had the media abuzz over some melting? Last…

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…

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…

Great News from Greenland

Guest essay by Dr. Patrick J. Michaels I recently returned from a trip to Greenland’s Jokabshavn Glacier, which discharges more ice than any other in the Northern Hemisphere. Our route…

How “Science” Counts Bears

Guest essay by Jim Steele, director emeritus, San Francisco State University The Inuit claim “it is the time of the most polar bears.” By synthesizing their community’s observations they have…

New study using GRACE data shows global sea levels rising less than 7 inches per century

Finds sea levels have risen over the past 9 years [2002-2011] at a rate of only 1.7 mm/yr, equivalent to 6.7 inches per century, matching tide gauge data rates. The…

NOAA exaggerates 2012 Greenland Ice Mass Loss by 10x

[UPDATE: Several commenters, including myself, have remarked on a mathematical error in the author’s work. I note this here in the expectation that the author will return to clarify and…

Remember that 'unprecedented' Greenland ice sheet surface melt that was allegedly caused by global warming? Never mind

We covered this extensively at WUWT last summer, including the “unprecedented claim” where a researcher said it was a recurring 150 year event that was ‘right on time‘. It turns…

Multiple, Intense, Abrupt Late Pleistocene Warming And Cooling: Implications For Understanding The Cause Of Global Climate Change

Guest essay by Dr. Don J. Easterbrook Dept. of Geology, Western Washington University, Bellingham, WA The results of oxygen isotope measurements from ice cores in the Greenland and Antarctic ice…

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…

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…

Global warming whacks Earth's poles – is there anything it can't do?

Reader View from the Solent writes: Global warming shifts the Earth’s poles. North Pole heads for Greenland “Global warming is changing the location of Earth’s geographic poles, according to a…

The beginning of the end: warmists in retreat on sea level rise, climate sensitivity

The forecast: It seems there’s less chance of gloom and doom these days. For sea level rise, now a maximum of about two feet by 2100. As for climate sensitivity,…

The Stokes-Kaufman contamination protocol – a 'sticky' wicket

Over at Climate Audit, Steve McIntyre has found yet another unexplainable inclusion of a hockey stick shaped proxy in the PAGES2K paper. What is most interesting about it is that…

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…

Validity of Marcott et al. PART II

Validity of Marcott et al. contention that “Global temperatures are warmer than at any time in at least 4,000 years” and “Global temperature….. has risen from near the coldest to…

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…
