The “Statisticians: ‘Global Cooling’ a Myth” story

28 10 2009

By William M. Briggs, professional statistician

Your statistical model!

J’accuse! A statistician may prove anything with his nefarious methods. He may even say a negative number is positive! You cannot trust anything he says.”

Sigh. Unfortunately, this oft-hurled charge is all too true. I and my fellow statisticians must bear its sad burden, knowing it is caused by our more zealous brethren (and sisthren). But, you know, it really isn’t their fault, for they are victims of loving not wisely but too well their own creations.

First, a fact. It is true that, based on the observed satellite data, average global temperatures since about 1998 have not continued the rough year-by-year increase that had been noticed in the decade or so before that date. The temperatures since about 1998 have increased in some years, but more often have they decreased. For example, last year was cooler than the year before last. These statements, barring unknown errors in the measurement of that data, are taken as true by everybody, even statisticians.

Th AP gave this data—concealing its source—to “several independent statisticians” who said they “found no true temperature declines over time” (link) Read the rest of this entry »





UK Met Office backpedals on Arctic Ice – “…unlikely that the Arctic will experience ice-free summers by 2020.”

28 10 2009

But they do say that “first ice-free summer expected to occur between 2060 and 2080″. By then there will be nobody that remembers this forecast.

Yet on the same day, bumbling Arctic explorer Pen Hadow says in a UK Telegraph interview:

To all intents and purposes the Arctic will be ice free in a decade. I do find the implications of this happening in my lifetime quite shocking.“.

Gosh, who to believe? Somebody that fakes biotelemetry data or somebody that won’t hand over climate data for replication studies?

From a Met Office press release on October 15th

Arctic sea-ice

The extent of Arctic sea ice has been decreasing since the late 1970s. In 2007 it decreased dramatically in a single year, reaching an all-time low. At the time it was widely reported that this was caused by man-made climate change and that the rate of decline of summer sea ice was increasing.

Modelling of Arctic sea ice by the Met Office Hadley Centre climate model shows that ice invariably recovers from extreme events, and that the long-term trend of reduction is robust — with the first ice-free summer expected to occur between 2060 and 2080. It is unlikely that the Arctic will experience ice-free summers by 2020. Read the rest of this entry »

Antarctica’s ice story has been put on ice

8 10 2009

From World Climate Report: Antarctic Ice Melt at Lowest Levels in Satellite Era

Where are the headlines? Where are the press releases? Where is all the attention?

The ice melt across during the Antarctic summer (October-January) of 2008-2009 was the lowest ever recorded in the satellite history.

Such was the finding reported last week by Marco Tedesco and Andrew Monaghan in the journal Geophysical Research Letters:

A 30-year minimum Antarctic snowmelt record occurred during austral summer 2008–2009 according to spaceborne microwave observations for 1980–2009. Strong positive phases of both the El-Niño Southern Oscillation (ENSO) and the Southern Hemisphere Annular Mode (SAM) were recorded during the months leading up to and including the 2008–2009 melt season.


Figure 1. Standardized values of the Antarctic snow melt index (October-January) from 1980-2009 (adapted from Tedesco and Monaghan, 2009).

The silence surrounding this publication was deafening.

It would seem that with oft-stoked fears of a disastrous sea level rise coming this century any news that perhaps some signs may not be pointing to its imminent arrival would be greeted by a huge sigh of relief from all inhabitants of earth (not only the low-lying ones, but also the high-living ones, respectively under threat from rising seas or rising energy costs).

But not a peep.

But such is not always the case—or rather, such is not ever the case when ice melt is pushing the other end of the record scale. Read the rest of this entry »





UAH: global temperature down in August by .181°C, SH sees biggest drop of 0.4°C

August 2009 saw a modest fall in the global average tropospheric temperature anomaly, from +0.41 deg. C in July to +0.23 deg. C in August. The tropical and Northern Hemispheric troposphere remain quite warm, but the Southern Hemisphere cooled by over 0.4 deg. C in the last month. Read the rest of this entry »





Spencer: Always question your results

Spurious SST Warming Revisited

Dr. Roy Spencer August 31st, 2009

My previous post described what I called “smoking gun” evidence of a spurious drift in the NOAA sea surface temperature (SST) product when compared to SSTs from the TRMM satellite Microwave Imager (TMI). The drift seemed to be mostly confined to 2001, almost a ’step’ jump. The moored buoy validation statistics of the TMI sea surface temperatures from Frank Wentz’s web site (SSMI.com) suggested that the TMI SSTs had good long-term stability.

But 2001 was also the year that the TRMM satellite was boosted into a higher orbit, which concerned me. I asked Frank about the effect of this event on the TMI SSTs (which also come from his web site). Frank couldn’t remember the details, but said he spent quite a bit of time correcting for the altitude change on the retrieved SSTs since the microwave emission of the sea surface depends upon the TMI instrument’s view angle with respect to the local vertical.

I know from our many years of work together on the AMSR-E Science Team that Frank is indeed a careful researcher, yet it seemed like more than a coincidence that the TMI and NOAA sea surface temperatures diverged during the same year as the orbit boost. So, I went back to see what might have caused the problem. I went back and thought about the different ways in which one can compute area averages from satellite data.

To make a long story short, because the orbit boost caused the TMI to be able to “see” to slightly higher latitudes, the way in which individual latitude bands are handled has a significant impact on the resulting temperature anomalies that are computed over time. The previous results I presented were for the 40N to 40S latitude band, which is nominally what the TMI instrument sees today. But before 2001, the latitudinal extent was slightly smaller than it was after 2001. Read the rest of this entry »





Satellite Imagery Shows Typhoon Vamco Has a Huge 45-mile Wide Eye

Typhoon Vamco is being as stubborn in its quest to live in the Pacific Ocean as Bill is in the Atlantic Ocean this past week, and NASA satellite data confirmed that the large storm has a huge eye, about 45 miles in diameter!

NASA’s Aqua satellite flew over Typhoon Vamco early today, Monday, August 24, and infrared imagery from Aqua’s Atmospheric Infrared Sounder (AIRS) instrument clearly showed Vamco’s 45-mile in diameter eye. Around the huge eye, AIRS showed Vamco’s cold high thunderstorm cloud temperatures were colder than minus 63 Fahrenheit. That’s an indication that the storm is still strong, and it is still a category one typhoon.

Also on NASA’s Aqua satellite, the Moderate Imaging Spectroradiometer (MODIS) instrument captured a stunning look at Typhoon Vamco’s clouds at 0255 UTC (August 23 at 10:55 p.m. EDT).

GISS Step 1: Does it influence the trend?

22 07 2009

Guest post by John Goetz

The GISStemp Step 1 code combines “scribal records” (multiple temperature records collected at presumably the same station) into a single, continuous record. There are multiple detailed posts on Climate Audit (including this one) that describe the Step 1 process, known affectionately as The Bias Method.

On the surface seems like a reasonable concept, and in reading HL87 the description of the algorithm makes complete sense. In simple terms, HL87 says that:

  1. The longest available record is compared with the next longest record, and the period of overlap between the two records is identified.
  2. The average temperature during the period of overlap is calculated for each station.
  3. The difference between the average temperature for the longer station and shorter station is calculated, and that difference (a bias) is added to all temperatures of the shorter station to bias it – bringing it in line with the longer station.
  4. The two records can now be combined as one, and the process repeats for additional records.

In looking at numerous stations with multiple records, more often than not the temperatures during the period of overlap are identical, so one would expect the bias to be zero. However, we often see a slight bias existing in the GISS results for such stations, and over the course of combining multiple records, that bias can be several tenths of a degree.

This was one of Steve McIntyre’s many puzzles, and we eventually figured out why we were getting bias when two records with identical overlap periods were combined: GISStemp estimates the averages during the overlap period. Read the rest of this entry »





And now, the most influential station in the GISS record is …

20 07 2009

Guest post by John Goetz

#17 - Selinsgrove, PA (in 2003)

The GISS temperature record, with its various adjustments, estimations, and re-estimations, has drawn my attention since I first became interested in the methods used to measure a global temperature. In particular, I have wondered how the current global average can even be compared with that of 1987, which was produced using between six and seven times more stations than today. Commenter George E. Smith noted accurately that it is a “simple failure to observe the standard laws of sampled data systems.” GISS presents so many puzzles in this area, it is difficult to know where to begin.

My recent post on the June, 2009 temperature found that the vast majority of temperatures were taken from airports and urban stations. This would cause some concern if the urban heat island (UHI) effect were not accounted for in those stations. GISS does attempt to filter out UHI from urban stations by using “nearby” rural stations – “nearby” meaning anything within 1000 KM. No attempt is made to filter UHI from airports not strictly listed as urban.

If stations from far, far away can be used to filter UHI, then it stands to reason some stations may be used multiple times as filters for multiple urban stations. I thought it would be amusing to list which stations were used the most to adjust for UHI. Fortunately, NASA prints that data in the PApars.statn.use.GHCN.CL.1000.20 log file.

The results were as I expected – amusing. Here are the top ten, ranked in order of the number of urban stations they help adjust: Read the rest of this entry »





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 »

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 »
