GISS: World’s airports continue to run warmer than ROW

15 07 2009

Guest post by John Goetz

AIRLNRAD1As noted in the previous post, GISS has released their monthly global temperature summary for June, 2009. This month’s whopping anomaly of 0.63C is once again much higher than that of RSS, UAH, and even NOAA, which is the source of the GISS temperature data. Not only is the anomaly higher than the other metrics, but it is trending in the opposite direction.

Temperature data from 1079 stations worldwide contributed to the analysis, 134 of them being located in the 50 US states. Data from essentially the same few stations have been used for the past twenty-four months. Many, many hundreds of stations that have historically been included in the record and still collect data today continue to be ignored by GISS in global temperature calculations.

Once again, the bulk of temperatures comprising the present-day worldwide GISS average come from airports – in this case 554 airports, according to the NOAA metadata from the V2 station inventory. In the US, the ratio of airports to total stations continues to run very high, with 121 out of the 134 reporting stations being located at airports.

Why worry about airports? Aside from recent posts on this site documenting problems with airport ASOS equipment in the US, WUWT has also documented a number of equipment siting problems, notably the typical close proximity of the equipment to a tarmac heat sink. Airports can introduce a mini-UHI effect where one would otherwise not be found.

The NOAA metadata is not entirely accurate, and several stations located at airports are not noted as such. Some examples include Londrina and Brasilia in Brazil, Ely / Yelland in Nevada, and Broome in Austrailia. Those stations were easy to find because they had “airport” (or some variant) in the station name. A check of coordinates using Google Earth confirmed the airport locations.

Let’s examine the metadata a little further, shall we? Read the rest of this entry »





A significant editorial on weather stations and data quality

5 06 2009

I was surprised to learn today, that one of the most prominent newspapers in the USA, the Orange County Register in the Los Angeles area, carried an editorial of which my work was the subject. It is quite a turnaround from the brush off I got last year by their Science Dude blogger who wrote a story on the warming of Santa Ana, CA.

By the way here is what the official NOAA weather station for Santa Ana looks like, note the a/c heat exchanger exhausts:

The editorial about my work was published in the OC Register on Monday, June 1st. I’ve reposted it below.

Editorial: Cooling down with global-warming data

U.S. and world temperature records are compromised by monitoring station errors.

An Orange County Register editorial

If fighting global warming may cost the economy $9.6 trillion and more than 1 million lost jobs by 2035, as the Heritage Foundation forecasts, it’d be a good idea to be sure there’s a sound basis before making such a massive sacrifice.

We’ve noted before that climate change is occurring as it always has, but the claim that man-made greenhouse gases will cause catastrophic temperature increases is based on questionable science and projections. Man’s contribution to greenhouse gases is minuscule. There are some theories but no convincing proof that increased emissions cause increased temperature.

Now another serious doubt has been raised concerning how much of the 1-degree centigrade increase over the past century allegedly caused by escalating emissions has even occurred.

“We can’t know for sure if global warming is a problem if we can’t trust the data,” said Anthony Watts, veteran broadcast meteorologist, who for three years organized an extensive review of official ground temperature monitoring stations, in conjunction with Dr. Roger Pielke Sr., senior research scientist at the Cooperative Institute for Research in Environmental Sciences and professor emeritus of the Department of Atmospheric Science at the University of Colorado.

Recent Differences Between GISS and NCDC SST Anomaly Data And A Look At The Multiple NCDC SST Datasets

18 05 2009

OR…. There are Increases in Trend with Each Update While The Causes of Downward Biases Are Deleted

Guest Essay by Bob Tisdale:

In the recent WUWT post Something hinky this way comes: NCDC data starts diverging from GISS, the differences between GISS and NCDC global temperature anomaly data was discussed. I commented that the GISS and NCDC global surface temperature anomaly data relied on two different SST datasets.

NCDC has their own SST anomaly dataset for their global surface temperature product, and they calculate anomalies against the base years of 1901 to 2000. GISS has used the NCDC OI.v2 SST anomaly data since December 1981, and before that they had used the Hadley Centre’s HADSST data. GISS then splices the two datasets together. This post does not discuss the HADSST data, but delves into the differences between the multiple NCDC SST anomaly datasets, one of which is used by GISS. Read the rest of this entry »





Audio from the NOAA/SWPC press teleconference

Well, it took me a week to get it, and finally here it is. Last Friday, May 9th as you may recall NOAA’s Space Weather Prediction Center had a teleconference which I was not invited to listen in on. But, Doug Biesecker kindly provided the audio.

This press teleconference coincided with SWPC’s announcement of going with the lower Solar cycle 24 prediction curve. Read the rest of this entry »

A note on ICECAP

8 05 2009

Many have inquired in comments what’s happened to the ICECAP website. My query to Joe D’Aleo was answered this morning, looks like servicide.

I noticed the outage yesterday, AM.  I had emailed and spoke to the hosting customer at [my] hosting support yesterday morning and they said server with ICECAP had hardware failure and they were working in it. I was traveling giving a talk in Chicago yesterday and assumed/hoped it was back up. Found out last evening still out with no estimate for return. I was about to upgrade to a dedicated server with them.
I will talk to manager when he comes in this AM. It was not a DOS [attack] it appears. I am home today so I can stay on their case. Usually the outages last minutes with reboot all that has been needed They assure me they back up everything. God forbid if not. I had 3450 stories stored.
Losing a server is about as stressful as you can get in daily work. Been there, done that. – Anthony




New Zealand glacier findings upset climate theory

2 05 2009

From the :
nzherald.co.nz

Fox Glacier is one of the worlds climate change indicators.

Fox Glacier is one of the world's climate change indicators.

Research by three New Zealand scientists may have solved the mystery of why glaciers behave differently in the Northern and Southern Hemispheres.

Geologist David Barrell of GNS Science, Victoria University geomorphologist Andrew Mackintosh and glaciologist Trevor Chinn of the Alpine and Polar Processes Consultancy have helped provide definitive dating for changes in glacier behaviour.

They were part of a team of nine scientists, led by Joerg Schaefer of the Lamont-Doherty Earth Observatory at Columbia University in New York, who used an isotope-dating technique to get very precise ages for glacial deposits near Mt Cook.

They measured the build-up of beryllium-10 isotopes in surface rocks bombarded by cosmic rays to pinpoint dates when glaciers in the Southern Alps started to recede. The technology is expected to be widely applied to precisely date other glaciers around the world.

Glaciers are sensitive indicators of climate changes, usually advancing when it cools and retreating when it warms.

The first direct confirmation of differences in glacier behaviour between the Northern and Southern Hemispheres, the new work topples theories based on climate in the Northern Hemisphere changing in tandem with the climate in the Southern Hemisphere.

The research argues that at times the climate in both hemispheres evolved in sync and at other times it evolved differently in different parts of the world. Read the rest of this entry »





Catlin Crew Out Of Time

An Arctic Blizzard

As reported here two weeks ago, April 30 is the last safe date to recover explorers from the Arctic.  The people who rescued Pen Hadow from the Arctic in May, 2003 said this :

“People are at risk – the ice breaks and it shouldn’t really happen. No one should expect to be picked up from there later than 30 April … Going to the Pole this time of the year is a bit stupid and you put a lot of people’s lives at risk.”

Another inconvenient TV meteorologist

27 04 2009

From WOOD-TV, Grand Rapids, MI

Chief Meteorologist Bill Steffen has been a familiar face in West Michigan since 1975.

MSNBC needs to read Bill’s Blog

April 26th, 2009 at 4:55 pm by Bill Steffen under Bill’s Blog, Weather

MSNBC is running a four-part series entitled Future Earth. On their website they say you can “find out why Earth’s climate machine — the North Pole — is melting alarmingly fast. Learn about our planet’s future, and how you can stop its decline.”

First, the North Pole is not “Earth’s Climate Machine”.  There is far more heat and area in the Tropics than at the North Pole.

Second,  YOU can’t stop it’s decline (assuming it’s declining)!  Nature is big – you personally are insignificant compared to nature.  Don’t you wish you had the power to control icecaps!  If you don’t mind some profanity, check out George Carlin’s take on “Saving the Planet”.

Third, MSNBC does not know “our planet’s future”.  The scenario they portray in this piece is about as remote a possibility in the near future (and more than likely the very far future) as the Lions going 16-0 next season.  The Antarctic icecap (which is much bigger than the Arctic icecap) has been growing.  In Sept. 1979 (first year of satellite data) the Antarctic icecap was 18.4 million sq. km.  In Sept. 2008, the Antarctic icecap was at 19.2 million sq. km. That’s a 30-year trendRead the rest of this entry »





Ice Target Zero

Shooting At a Rapidly Moving Target

Guest post by Steven Goddard

Arctic ice area has recovered to normal (one standard deviation) levels, so ice area no longer matters.  The issue is now thickness, which is measured by a team of explorers (Catlin) with a tape measure, who intentionally seek out flat (first year) ice for their route.

The team systematically seeks out flatter ice because it is easier to travel over and camp on. Typically, the surface of first‐year ice floes is flatter than that of multi‐year ice floes.

Catlin Arctic Ice Survey first report offers no original drilling data, but anecdotally confirms satellite measurement

Note: One of the many integrity issues with Catlin is that none of their photos can be dated. Even embedded EXIF information (including date/time done by most digital cameras in use today) has been removed from gallery photos on the website. For all we know this photo above they included in their just released report could have been taken during training. The high photographic angle suggests the photographer was standing on something, but what? Further, no raw data is offered in their first report, we are expected to take it on faith I suppose. Given their admittedly fraudulent biometric readings, and lack of candor on their ice radar, how can we trust anything they publish? So far for a “science” mission I remain unimpressed with the effort or the transparency. – Anthony

Catlin Report Confirms that Satellite Data is Accurate

Catlin just came out with their first ice report (PDF)

The ice thickness measurements that Pen and the team have been able to phone in imply that they are travelling over predominantly thick first‐year ice. Satellite imagery of the area, especially passive microwave imagery (e.g. AMSR and QuikScat data), indicates the area is indeed covered primarily with first‐year ice and a scattering of multi‐year ice floes.

The report summary is :

The results collected in the first month of the Catlin Arctic Survey point to an unexpected lack of thicker Multiyear Ice. Read the rest of this entry »





Revealed: Antarctic ice growing, not shrinking

Article from: The Australian

ICE is expanding in much of Antarctica, contrary to the widespread public belief that global warming is melting the continental ice cap.

The results of ice-core drilling and sea ice monitoring indicate there is no large-scale melting of ice over most of Antarctica, although experts are concerned at ice losses on the continent’s western coast. Read the rest of this entry »





Quote of the Week #3

12 04 2009
qotw_cropped

Image from WUWT reader "Boudu"

This QOTW is from MIT’s  Dr. Richard Lindzen, from his response to critics on the WUWT post: Lindzen on negative climate feedbacks

…it has become standard in climate science that data in contradiction to alarmism is inevitably ‘corrected’ to bring it closer to alarming models.  None of us would argue that this data is perfect, and the corrections are often plausible.  What is implausible is that the ‘corrections’ should always bring the data closer to models.






What if the Catlin Arctic Ice Survey is for naught?

Guest post by Steven Goddard

Hell Hath No Fury….
A very hard day.

Catlin team member Ann Daniels had another very difficult day.

Today has been a difficult day of highs and lows, particularly for Ann, whose morning got off to a particularly bad start. In order to power the different technical components of the kit, the team use large batteries, which need to be heated to a certain temperature in order to extract the maximum amount of power. The process of heating batteries involves Ann, sitting by her stoves for several hours, using a specially insulated piece of equipment to capture the steam from boiling water, in order to get the batteries to the correct temperature.
Ann reached her lowest point of the expedition so far, when after tending the boiling pans of water for several hours, she realised she had pre-heated the wrong battery and had accidently picked up the dead battery from the previous day. It was a painful and frustrating realisation at the end of a cold morning.
On the plus side, at the end of the day, Ann felt warm enough to take off her sledging jacket when getting into her sleeping bag for the night. This is the first time in the 41 days of the expedition so far that she has felt warm enough for this luxury. She adds that she was still wearing 3 pairs of trousers, 2 thermal top layers, 2 hats and 4 pairs of gloves, but still, quite a landmark in the expedition so far!

Consider the following scenario.  All goes well and the team arrives home safely some time in the next six weeks.  Now, suppose that the Arctic continues to show recovery this summer, and the realization sinks in that the very premise of the expedition may have been flawed.

Catlin Crew Officially Has Hypothermia (and Frostbite)

Hypothermia Posted by Gaby Dean
Monday, 06 Apr 2009 15:58
In disadvantaged inner cities it’s known in medical circles as Urban Hypothermia.  GPs adopted the term after seeing an increase, during winter, of elderly patients who have switched off their heating, fearful of the cost, and become ill as a result because of the cold.

Chronic, as opposed to acute, hypothermia is the official term. Read the rest of this entry »
