Giving thanks

As this year draws to a close, I think back about what I’ve accomplished on this blog in the last year, and it occurs to me that I have a lot of people to thank. It truly has been a team effort in a lot of ways, with many people contributing from many different angles…

Weathering and Thermometer Shelters

Former Virginia State Climatologist Patrick J. Michaels wrote an op-ed about his paper with Ross McKitrick from Canada’s University of Guelph in an American Spectator column today about the surface temperature record. This paragraph really caught my eye: “Weather equipment is very high-maintenance. The standard temperature shelter is painted white. If the paint wears or…

Blogging Holiday – please drive/bike/walk safely

I’m taking a few days off blogging for friends and family. Seeing the pandemonium that has gripped the streets of my town while people scurry about trying to pull off that last minute shopping, and seeing my in-laws already getting into a small accident (even though they tried to avoid the traffic glut) and seeing local cycling…

Moon and Mars show tonight, Sunday Dec 23rd

Sky note:  After sunset on Sunday, Dec. 23rd, the full Moon and Mars will rise in the east less than 2 degrees apart. They’ll be two brightest objects in the evening sky, as Mars is very near it’s closest approach (opposition) to Earth, which happened just a couple of days ago.  It will look something like…

Record cold events around the world in 2007

Below is an opinion from the Washington Times by Geophysicist David Denning, to which I’ve added photos and links to the events he’s written about.   A caveat: I caution the reader that annual weather does not equate to long term climate. Yes we have had a number of record cold events in 2007, and the winter in…

U.S. Senate Report: Over 400 Prominent Scientists Disputed Man-Made Global Warming Claims in 2007

U.S. Senate Report: Over 400 Prominent Scientists Disputed Man-Made Global Warming Claims in 2007  from this link: http://epw.senate.gov/public/index.cfm?FuseAction=Minority.SenateReport The variety and reach of this is quite large. This is a report gathered from many independent publications, it is not one of those “Internet Petitions” which can be easily loaded up with fake names by those…

The Best Christmas Present Anybody Could Ever Have

My coffee buddy, Butte County Sheriff Perry Reniff helps Alexis Dominguez exit the helicopter (Photo: Bill Husa, Chico Enterprise Record)  Today was a good day. No, strike that, today was a GREAT day! The saga of the Dominguez family lost in the snow looking for a Christmas tree hit home with me in a big…

Study: Greenland prior eras as warm or warmer than today

I was forwarded a slide show presentation done by Thomas Lowell et al of the University of Cincinnati titled: Organic Remains from the Istorvet Ice Cap, Liverpool Land, East Greenland: A Record of Late Holocene Climate Change It was presented last week at AGU’s Greenland Climate Change Past and Present session. It has some very interesting…

Told Ya So!

As I blogged about earlier this year, Vista sucks. Now comes vindication of my views from PC World’s The 15 Biggest Tech Disappointments of 2007 unsurprisingly, Windows Vista has been rated the most disappointing product of 2007.  It’s delicious irony that this OS runs best on an Apple Macbook. See below. Maybe Steve Ballmer will finally…

One more thing to worry about

While we are all recovering from the news of the terrible fate that awaits us as outlined recently in Bali, astronomers have, for the first time, witnessed a super-massive black hole hitting a nearby galaxy with a “death-star-like” beam of energy. The story also has a video with simulations, pictures, and explanations. “The ‘death star galaxy,’…

Climate Audit back up soon

I’m getting lots of emails from worried folks about the status of the Climate Audit website.  It’s a DNS snafu caused by closing a billing for hosting service that isn’t used anymore. I’ve already cured the problem but the trickle through of new DNS entries takes time, web-wide. For those with Windows try this: Open…

Significant Storms Headed to Northern California

You can click the image to see an animation that shows the current data at the time you are viewing, which depending on when you click, may not match the image above. Looks like after the midwest and east coast got heavy winter weather, now it’s our turn here in California. These are two cold wet storms…

Spotting Weather Stations in SFO

San Francisco’s official weather stations, new and old locations are in this photo – can you find them? Last Thursday evening I had the pleasure of meeting up with Steve McIntyre, Steve Mosher, and “jeez” (who lives in San Francisco, and currently wishes to remain anonymous) from Climate Audit. We had dinner at Umbria in…

From AGU – the cause of Aurora Borealis and TSI questions

Scientists think they have discovered the energy source of auroras borealis and australis, the spectacular upper atmospheric color displays seen in the highest latitudes of the our planet. At the same time, this discovery raises questions about our understanding of Total Solar Irradiance (TSI). Results were presented Tuesday at the American Geophysical Union  (AGU) meeting. NASA…

Signs of a new solar cycle?

From NASA: The solar physics community is abuzz this week. No, there haven’t been any great eruptions or solar storms. The source of the excitement is a modest knot of magnetism that popped over the sun’s eastern limb on Dec. 11th, pictured below in a pair of images from the orbiting Solar and Heliospheric Observatory…

Off to AGU

I’m off to San Francisco to the AGU meeting and to meetup with Steve McIntyre and others. So I won’t be posting for awhile. I’ll have some new material over the weekend.

How not to measure temperature, part 45

I’ve covered California’s temperature stations and their exposure problems extensively, now it’s time to head north to Alaska. When you think of Alaska, you think of cold, snowy, pristine remote wilderness, right? Surely there are no worries about urbanization affecting thermometers in the great white north. Well as I’ve said before, the NOAA MMTS system…

Spot the thermometer in this photo

I have a new tool for evaluation of the micro-site measurement environment near thermometers. The first site I’ve surveyed has not one but two potential biases. Can you spot them? Can you guess what they are? This may be the first image of it’s kind. I don’t recall seeing IR photo’s of NOAA thermometers in situ…

USHCN National Weather Station Quality Plot

Early in the project, one of the criticisms heard against the surfacestations.org effort was that there had been “cherry picking” going on in the selections of stations to survey, and that the project wasn’t reaching a wide area. In this first map of it’s kind, one can clearly see the how the quality distribution of the…

How not to measure temperature, part 44

I’ve seen a couple of weather stations mounted on rooftops before, for example the station in Eureka, CA was on the roof of the post office for many years. This station in downtown Oakland, CA is unique because not only is it in on a rooftop, in the middle of an urban setting, it’s also…

NASA/NOAA may have lost GOES East satellite

  The GOES East satellite (GOES 12) went through a station keeping maneuver (used to maintain orbit and attitude) yesterday, and then shortly afterwards communications ceased. GOES 12 is no longer delivering satellite imagery. This satellite is used for most eastern US weather forecasting, as well as tropical storm tracking and marine forecasting. Here is the bulletin…

How not to measure temperature, part 43

 Continuiung our tour of California climate monitoring stations, we visit the Portola train yard, where they not only switch freight, but measure the temperature too. This station is # 04-7085 and is part of the COOP climate monitoring network operated by the NWS.  The wealth of roadbed ballast gravel and vehicles makes this location almost an…

How not to measure temperature, part 42

Continuing our tour of some of the worst climate monitoring stations in California, we come to San Jose. In previous posts we’ve seen stations put next to parking lots. In this case we have not only that, but also a station next to a major city intersection. It never ceases to amaze me when I find…

How not to measure temperature, part 41

Lately we’ve been touring COOP weather stations in California to illustrate how they are prone to biases in their siting. This problem is documented in the recent paper LaDochy, S., R. Medina, and W. Patzert. Recent California climate variability: spatial and temporal patterns in temperature trends which is available for review in my post here. The picture below…
