Climategate Update III

By -



In Update I, we discuss the deletion of the raw data that comprised the CRU database, the most widely used to “demonstrate” global warming.  In Update II, we talked about the warm bias in the data caused by improperly sited thermometers.

Here is the CRU temperatures for the last 150 years.



In part III, we discuss what may be an intentional bias built into the CRU computer code.  This is the part of Climategate that has been underreported.  It is based on a file called “Harry Read Me” which part of the FORTRAN code where a programmer “comments” on what he/she is doing and why.  I have read the Harry Read Me but have not attempted to analyze the code itself.  It has been a long time since I did FORTRAN programming in college and I don’t trust my skills.  If you wish to look at the code itself and multiple comments on it, go here and here.

I can state:  It is absolutely clear that the code is a complete mess.  Nothing any rational person would bet trillions of dollars on.

And, there are programmers who have examined the code who allege there are subroutines that artificially lower temperatures in the 1930's and inflate them in recent years.  I cannot confirm this.  


What I can confirm is that regional temperatures seem not to confirm the worldwide trends depicted in the CRU temperature plots.

Great Britain:


This is from the longest continuous thermometer record in the world.  Blue is 20th Century.  Red is 18th Century.  There is no significant warming.  Of course, this is just one point in the world.  Lets look at another.  New Zealand.

Little warming in 150 years.

Steve McIntyre (who more and more looks like he should have been given the Nobel Prize) identified this two years ago as the "Where's Waldo" problem:  None of the regional raw data plots seem to show the huge warning the world data plots from CRU show.  Let me state it another way: If Britain and New Zealand don't show the huge rise, there must be a giant rise somewhere else to average into the large 1990's rise shown by the CRU (and NASA) databases.  This illusive giant rise was named "Waldo" by McIntyre.

He couldn't find the rise in the United States, Antarctica (/www.climateaudit.org/?p=1985) or South America ( www.climateaudit.org/?p=44 ) or China.

So, here is where we are:  CRU's data says there has been a giant temperature rise, but its system for computing the rise is -- at best -- a mess.  Some contend there is fudging in the code (which I cannot confirm).  Steve McIntryre and others are not able to find, in the regional data, a large temperature rise that tracks CRU's.

But, its got to be out there somewhere, right?  After all the Arctic ice is melting and, according to the Associated Press, as recently as November 2, 2009, Kilimanjaro is melting due to "global warming."

Maybe not.  The subject of the next post.

UPDATE:  I hardly get these posted and there is a new development.  "Waldo" isn't in Alaska, either.  This is also pertinent to update IV (out of order) with regard to Arctic ice.

Hilary's Forecast Path Shifts West; Updated 9:20am PDT

By -

The forecast path of the center of Hilary has shifted a bit to the west. This increases the threat to the Southland, especially in terms of flooding.  Rainfall Note the heavy rains are forecast for Los Angeles County. Serious flash flooding may result. Because the forecast path has shifted to the west, that increases the threat of serious flooding in Los Angeles County north into Yosemite and the southern Sierra. It lessens the threat in Utah and western Arizona. While the threat of widespread flooding in Utah and Arizona lessens, note that some thunderstorms with localized heavy rain show up on the map.  In Nevada, the more western path increases the risk of serious flooding around Mt Charleston and into the central part of the state.  Here is the updated  (9am PDT) flash flood risk map. Wind There are already about 40,000 people without power in California, mostly in the center of the state.  The maps above are the peak gusts forecasted with the storm. The highest winds, in general,

-- Note, more current info available. Scroll up. --- Updated Information as of 8am PDT You are risking your life if you attempt to travel through the purple area.  While the rain has not begun in coastal California, I would urge you to use this time to make any preparations. Power outages have occurred already in southeast California. Here is the latest radar as of 7:55am PDT. As of 6:40am PDT , the radar indicates moderate to heavy rain falling over desert areas of Southern California and far western Arizona (click to enlarge).  Rainfall amounts for the 24 hours ending at 7am PDT show more than two inches have already fallen. There are reports from reliable sources that roads are already washed out and that people are stranded in isolated parts of the desert.  Below is a high-resolution computer model's rainfall forecast from 5am PDT to 11pm PDT Sunday. More than a foot of additional rain is forecast to fall. This will lead to catastrophic flooding.  Here is a map of current watc

Update on Tornado and Wind Potential; 12 Noon PDT

By -

There was at least one tornado and at least one funnel cloud yesterday.  --- original forecast --- Hilary (the swirly symbol) continues to move NNW paralleling the coast of Baja California, Mexico. The area outlined in red has a significant risk of tornadoe s the rest of the afternoon.  Below is a list of peak wind gusts so far.  Peak winds may increase farther north as the afternoon progresses.  Addition at 12 noon PDT: Sure enough, winds have increased.  Note: If you are in the San Diego area, I recommend not  traveling east on I-8. Heavy rains may cause flash flooding that will involve the highway.
