An interesting plot twist – call it an anomaly

We’ve covered this topic before, but it is always good to mention in again. Howard Goodall asks this on Twitter: “Ever wondered why climate scientists use anomalies instead of temperatures? 100 years of catastrophic warming in central England has the answer.” He provides a link to the Central England Temperature data at the Met Office…

UAH finds a warming error in satellite data, lowers “tropical hotspot” temperature trend, contradicts IPCC models

From the University of Alabama, Huntsville via email from Dr. John Christy. Weather Satellite Wanders Through Time, Space, Causing Stray Warming to Contaminate Data In the late 1990s, the NOAA-14 weather satellite went wandering through time and space, apparently changing the record of Earth’s climate as it went. Designed for an orbit synchronized with the…

DO-IT-YOURSELF TEMPERATURE RECONSTRUCTION

Guest essay by Dr Michael Chase SCOPE This article describes a simple but effective procedure for regional average temperature reconstruction, a procedure that you, yes you dear reader, can fully understand and, if you have some elementary programming skills, can implement. To aid readability, and to avoid the risk of getting it wrong, no attempt is…
