Arctic Ice Thickness Measured From Buoys
Guest Post by Steven Goddard The Catlin Arctic Survey has generated quite a bit of discussion, more because of the difficulties they have faced than because of the scientific merit…
Guardian: Al Gore says "business leaders see the writing on every wall they look at"
Above: Al’s high five on ice caps (gone in five years) Guest post by Steven Goddard In today’s Guardian, Al Gore is quoted as saying: Gore says he has also…
Poll and Polar Ice Trends
Guest post by Steve Goddard Yesterday, Dr. Walt Meier from NSIDC again graciously updated us about the NSIDC sensor problem, and also about his current thinking with respect to polar…
NSIDC's Walt Meier responds on the sensor issue
I assume that everyone has seen the post on our website discussing the changes that NSIDC has instituted to make our sea ice data available again. I don’t want to…
George Will's battle with hotheaded ice alarmists
Regular WUWT readers know of the issues related to Arctic Sea Ice that we have routinely followed here. The Arctic sea ice trend is regularly used as tool to hammer…
Sea Ice Sensor Degradation Hits Cryosphere Today
You may recall that I posted about how the National Snow and Ice Data Center has an issue with the DMSP satellite sensor channel used to detect sea ice. Cryosphere…
NSIDC: satellite sea ice sensor has "catastrophic failure" – data faulty for the last 45 or more days
The DMSP satellite is still operating, but the SSM/I sensor is not Regular readers will recall that on Feb 16th I blogged about this graph of arctic sea ice posted…
Errors in publicly presented data – Worth blogging about?
In the prior thread I raised a question of why there was a large downward jump in sea ice extent on the graph presented by NSIDC’s Artic Sea Ice News…
NSIDC makes a big sea ice extent jump – but why?
Something odd is going on at the National Snow and Ice Data Center. Look at this image: The image is directly from NSIDC’s Artic Sea Ice News page today. Of…
Arctic Sea Ice Increases at Record Rate
Arctic Sea Ice Increases at Record Rate Guest Post by Jeff Id on February 3, 2009 Something I’ve been interested in for the last several months is sea ice data. What…
Antarctica warming? An evolution of viewpoint
Above: Mt Erebus, Antarctica picture by Sean Brocklesby A press release today by the University of Washington makes a claim that Antarctica is warming and has been for the last…
Polar Sea Ice Changes are Having a Net Cooling Effect on the Climate
A guest post by Steven Goddard One of the most widely discussed climate feedbacks is the albedo effect of polar sea ice loss. Ice has a relatively high albedo (reflectance)…
UAH is out, like RSS it is down a bit
Although the webserver file for the UAH dataset has not been updated yet, the man who is “in the know” because he’s a major part of the process has released…
NSIDC issues documentation corrections – WUWT guest post a catalyst
You may recall the guest post from Jeff Id of the Air Vent I carried about a week ago called Global Sea Ice Trend Since 1979 – surprising In that…
NOAA Determines Ribbon Seals Should Not be Listed as Endangered – say ice will continue to form
(Note: image above and my emphasis added below. What is unlcear is what climate models the reviewed and whether they accepted or rejected it’s results. – Anthony) Contact: Sheela McLean …
Polar Albedo Feedback
by Steven Goddard Today is a day of note in Antarctic. The sun has reached it’s highest point in the sky, and never sets. The amount of incoming solar radiation…
The CO2 – Temperature link
Guest Post By Frank Lansner, civil engineer, biotechnology. More words on the topic first presented here: http://icecap.us/images/uploads/FlaticecoreCO2.pdf I wrote: It appears from this graph that CO2 concentrations follows temperature with…
Global Sea Ice Trend Since 1979 – surprising
Much importance has been ascribed to tracking the change in Arctic sea ice, but what about the global trend? That doesn’t seem to get much press. However there is some…
Gore: "Entire north polar ice cap will be gone in 5 years"
This is from his address in Germany, recorded from German TV: Write this date down so you can contact Mr. Gore in 5 years, then place your bets. I’m sure…
Something is rotten in Norway – 500,000 sq-km of sea ice disappears overnight
I had planned to do a post yesterday evening about how sea ice area and extent had returned to very near normal levels. But I was tired, so I saved…
Sea ice area approaching the edge of normal standard deviation
10/31 NEWS: See updated graphs here UPDATED: 10/22/08 The new images below are even closer Watching arctic sea ice rebound this year has been exciting, more so since a few…
Researchers find arctic may have had less ice 6000-7000 years ago
I love field work. I think any climate scientist that basically becomes a data jockey should be forced to go out and examine real world measurement systems and weather stations…
