Alarmists throw in the towel on poor quality surface temperature data – pitch for a new global climate reference network

From the Journal of International Climatology and the “if you can’t beat ’em, join ’em” department. To me, this feels like vindication. For years, I’ve been pointing out just how bad the U.S. and Global Surface monitoring network has been. We’ve seen stations that are on pavement, at airports collecting jet exhaust, and failing instruments…

Despite attempts to erase it globally, "the pause" still exists in pristine US surface temperature data

As readers know, the recent paper Karl et al. 2015, written by the head of the National Climatic Data Center now NCEI, went to great lengths to try to erase “the pause” from the surface temperature record using a series of adjustments. Those adjustments are deemed unacceptable and criticized by some climate scientists, such as…

Can Temperature Adjustments Right a Wrong?

Guest Post by John Goetz Adjustments to temperature data continue to receive attention in the mainstream media and science blogs. Zeke Hausfather wrote an instructive post on the Climate Etc. blog last month explaining the rationale behind the Time of Observation (TOBS) adjustment. Mr. Hausfather pointed to the U.S. Climate Reference Network (CRN) as a…

NOAA shows 'the pause' in the U.S. surface temperature record over nearly a decade

NOTE: significant updates have been made, see below. After years of waiting, NOAA has finally made a monthly dataset on the U.S. Climate Reference Network available in a user friendly way via their recent web page upgrades. This data is from state-of-the-art ultra-reliable triple redundant weather stations placed on pristine environments. As a result, these…

NOAA's 'Janus moment' – while claiming 'The American public can be confident in NOAA’s long-standing surface temperature record', they fund an experiment to investigate the effects of station siting and heat sinks/sources on temperature data

NOAA’s impersonation of the two faced god Janus just proved my point about station siting issues with their actions that speak louder than words. While there’s all this caterwauling about my PBS News hour interview, and my statements were apparently so threatening that NOAA itself asked PBS to publish a rebuttal in their apologetic story…

Errors in Estimating Mean Temperature – Part II

Guest post by Lance Wallace Last week (Aug 30), Anthony Watts posted my analysis of the errors in estimating true mean temperatures due to the use of the (Tmin+Tmax)/2 approach widely used in thousands of temperature measuring stations worldwide: http://wattsupwiththat.com/2012/08/30/errors-in-estimating-temperatures-using-the-average-of-tmax-and-tmin-analysis-of-the-uscrn-temperature-stations/ . The errors were determined using the 125 stations in NOAA’s recently-established US Climate Reference…
