'Game changer' – Antarctic melt due to warm water, not air temperature

New paper from NOAA demonstrates that El Niño has more impacts than climate on winter weather in the USA

While AP’s Seth Borenstein cites opinions of activist scientists in erroneously claiming that ‘climate change’  increasing atmospheric moisture is the main driver for winter weather events, it turns out that…

NCDC's new USHCN hockey stick trick

Yesterday, NCDC released Version 2.5 of the USHCN data set. For those who don’t know, this is the U.S. Historical Climatology Network (USHCN) which NCDC considers a “gold standard” for…

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…

PBS backtracks due to viewer pressure

This just appeared on the PBS Blog, apparently the mere presence of my interview was enough to push NOAA into responding. It seems they are in full damage control mode.…

Not so hot – ocean temperatures around the USA are not anywhere near record levels

While there’s wailing and gnashing of teeth over the US CONUS surface temperature being the “hottest ever” a cursory review of the sea surface temperatures in U.S.Coastal waters shows no…

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