The Yin and Yang of Holocene Polar Regions

Guest post by Renee Hannon Introduction The Arctic and Antarctic regions are different and yet similar in many ways. The Arctic has ocean surrounded by land and the Antarctic is a continent surrounded by water. Both are cold, glaciated and located at Earth’s poles some 11,000 miles apart. While sea ice has been retreating in…

According to the main hypothesis, warming since 1951 has been due almost exclusively to the increase in GHGs (greenhouse gases), of which CO2 is the most important one. The IPCC does not find anything else…

Modern Climate Wavelet Patterns

Guest Post by Renee Hannon Wavelet analyses of modern global temperature anomalies provides an excellent visualization tool of temperature signal characteristics and patterns over the past 150 years. Scafetta recognized key temperature oscillations of about 9, 20 and 60-years using power spectra of global surface temperature anomalies. There has been much discussion about the 60-year…

Scientific Apophenia

Guest Essay by Kip Hansen   Science, as a whole, advances or fails to advance in large part in a direct relationship to the presence or absence of bias in its research efforts.  There are many types of bias, and these have been discussed in the pages of various Climate Science blogs and publications over…

Quiz: Which 30-Year Warming Period Is Recent?

Guest Post by Bob Tisdale THREE MAPS ILLUSTRATING SIMILAR GLOBAL SURFACE TEMPERATURE CHANGES OVER DIFFERENT 30-YEAR PERIODS The GISS map-making webpage allows users to create global maps of surface temperature anomalies for specific time periods or to create maps of the change in surface temperatures over user-defined time periods based on local linear trends. My…

More Alarmist Nonsense with the Release of the Redundant* NOAA Global Temperature Data for February 2016

Guest Post by Bob Tisdale *Or Maybe the GISS Land-Ocean Temperature Index is Redundant. In the post Alarmism Cranked Up to Absurd Level, we discussed the misleading media reports about the temporary February 2016 El Niño-related uptick in monthly global surface temperature data from the Goddard Institute of Space Studies. There have been numerous new…
