Inverse Underwater Hockey Sticks?

From the University of Toronto,  Underwater ‘tree rings’ Calcite crusts of arctic algae record 650 years of sea ice change Almost 650 years of annual change in sea-ice cover can been seen in the calcite crust growth layers of seafloor algae, says a new study from the University of Toronto Mississauga (UTM). “This is the…

The early chill in the Arctic continues

Temperature above 80 degrees north drops below freezing early, and continues to drop. Many people have been watching the remarkable early drop in air temperature at the DMI plot here: This drop looks to be about two weeks early. As this next analysis of sea surface temperature shows, much of the area is below freezing.…

UW issues statement on the ‘North Pole Lake’

From the University of Washington: Santa’s workshop not flooded – but lots of melting in the Arctic By Hannah Hickey Santa’s workshop at the North Pole is not under water, despite recent reports. A dramatic image captured by a University of Washington monitoring buoy reportedly shows a lake at the North Pole. But Santa doesn’t…

Remarkable correlation of Arctic sea ice to solar cycle length

This is interesting, especially since Solar Cycle 23 was quite long. The Hockey Schtick writes: A paper published by the Danish Meteorological Institute finds a remarkable correlation of Arctic sea ice observations over the past 500 years to “the solar cycle length, which is a measure of solar activity. A close correlation (R=0.67) of high significance (0.5…

Avaaz! Save the world from a slushy death, just £2

People send me stuff. This is an email solicitation claiming that if you send Avaaz £2 a week (About $3.07 USD at current exchange rate) they’ll somehow be able to help NSIDC’s Julienne Stroeve get started putting back that Arctic ice, much like as a previous subscriber, you may have given money to help dolphins from…

A data review to supplement the UK Met Office ‘Disappointing Weather Meeting’

A graphical review of 14.5 years disappointing UK weather Guest essay by Neil Catto A meeting today (18th March 2013) took place at the UK Met Office HQ in Exeter. See the report here: http://www.metoffice.gov.uk/news/releases/archive/2013/meeting-unusual-seasons It was arranged to include the best climatologists and meteorologists to gain better understanding of the ‘disappointing UK weather over…

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 out jet stream changes and thin cloud cover was the driver. Also “the analysis shows that ocean temperatures and Arctic sea-ice cover were relatively unimportant…

SEARCH sea ice contest, call for contributions

WUWT has participated for the last two years, and I’ll post up a poll for the WUWT submission tomorrow. In the meantime, you can get a look at the current state of the Arctic Sea Ice at the WUWT Sea Ice Reference Page.

Modeling sea ice loss

From Wiley Study explores atmospheric impact of declining Arctic sea ice There is growing recognition that reductions in Arctic sea ice levels will influence patterns of atmospheric circulation both within and beyond the Arctic. New research in the International Journal of Climatology explores the impact of 2007 ice conditions, the second lowest Arctic sea ice…

Climate models getting worse than we thought

New paper finds climate models are getting worse rather than better Via the Hockey Schtick: A paper published today in Geophysical Research Letters finds that the latest climate models are performing even worse than the earlier generations of climate models in predicting “…both the mean surface air temperature as well as the frequency of extreme…

Michael Tobis has bupkis

UPDATES have been added:  see below. Not only does Tobis have bupkis, he’s been caught out in a Janus moment from 2010 where he says the exact opposite. – Anthony I wrote a post yesterday pointing out how a WWF zealot immediately linked a heavy snowfall event in Moscow, Russia to ‘global warming’. Marc Morano…

Matt Ridley: A Lukewarmer’s Ten Tests

What it would take to persuade me that current climate policy makes sense Guest post by Matt Ridley I have written about climate change and energy policy for more than 25 years. I have come to the conclusion that current energy and climate policy is probably more dangerous, both economically and ecologically, than climate change…

Alice in Wonderland science

Our energy and environment deserve better – in South Africa and Qatar Guest post by Dr. Kelvin Kemm A few weeks ago, perhaps as a prologue to the “global warming disaster” convention in Doha, Qatar, South Africa’s Department of Environment Affairs took out a full-page advertisement in our country’s newspapers, promoting National Marine Week.

Hamster wheels and sea ice explained

From the University of Calgary Utoday: Melting Arctic ice cap at record low – By Heath McCoy Think of a poor hamster on a spinning wheel, caught up by momentum and unable to stop until it’s overwhelmed, sent tumbling, crashing out of control inside. That’s the analogy John Yackel, head of the department of geography, makes…
