Which mercury reading in Mercury is the right one?

How can two stations less than 1/2 mile apart be so different? How can one set a new record and best it by two degrees while the other doesn’t? I…

Australia and ACORN-SAT

Guest Post by Willis Eschenbach As Anthony discussed here, some Australian climate scientists think that there was an “angry summer” in 2012. Inspired by the necromantic incantations in support of…

The monthly report NOAA never produces – from the Climate Reference Network

Here is the latest monthly value from the state of the art Climate Reference Network, (CRN) which never seems to make it into NOAA’s monthly and yearly climate reports. But,…

Via experiment, NOAA establishes a fact about station siting: 'nighttime temperatures are indeed higher closer to the laboratory'

WUWT readers may recall that I wrote about this experiment being performed at Oak Ridge national Laboratory to test the issues related to station siting that I have long written…

Announcing the first ever CONUS yearly average temperature from the Climate Reference Network

UPDATE: NOAA plans to release SOTC at 1PM EST today. Look for updates soon and a special report on today’s release. The map below will automatically update when we have…

New national temperature resource almost ready

I had hoped to have this ready in time for heat wave season, as it would have been quite useful in July. Pursuant to my post about July average temperatures…

A new paper showing how UHI and energy consumption are linked to long-term temperature change in China

Dr. Roger Pielke Sr. highlighted this major new paper in JGR yesterday, I consider it important as it relates to the works I’m doing on station siting. The key points…

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…

Sea Ice News – Volume 3 Number 11, part 2 – other sources show no record low Arctic ice extent

Earlier today in part1, I posted about the new record low claimed by NSIDC: Sea Ice News – Volume 3 Number 11, part 1 – new Arctic satellite extent record.…

An 'inconvenient result' – July 2012 not a record breaker according to data from the new NOAA/NCDC U.S. Climate Reference Network

I decided to do myself something that so far NOAA has refused to do: give a CONUS average temperature for the United States from the new ‘state of the art’…
