Greenland Ice Core CO2 Concentrations Deserve Reconsideration

Guest post by Renee Hannon IntroductionIce cores datasets are important tools when reconstructing Earth’s paleoclimate. Antarctic ice core data are routinely used as proxies for past CO2 concentrations. This is because twenty years ago scientists theorized Greenland ice core CO2 data was unreliable since CO2 trapped in air bubbles had potentially been altered by in-situ…

Earth’s Ice Ages

By Andy May The phrase “Ice Age” is poorly defined and often abused, so let’s first define the climate state during most ice ages. It is called “Icehouse Earth.” The earth is in an icehouse state when either or both poles are covered in a thick, permanent icecap (Scotese 2015). Today, both poles are covered…

The big Arctic Sea-Ice shift of 2007: Ice refuses to melt

by Javier I have maintained since 2015 that in the 2006-2007 season the Arctic underwent a cyclical phase shift, and the rapid sea-ice melting observed over the previous decades ended. A few scientists predicted or explained this shift based on their study of multi-decadal oscillations (see bibliography). They were ignored by mainstream climatology and the…

Strong Arctic sea-ice growth this year

Guest Post by Javier February is not over, and Arctic sea-ice extent is already over half a million square kilometers higher than last year at this day. The growing season has not ended, and 2019 Arctic sea-ice extent is already higher than the previous four years and six out of the last 14 years.  …

The planet is no longer warming

Guest Post By Javier         We define “warming” as a positive rate of temperature change over time. 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…

The Heartland Greenpeace Business Report

By Andy May An intriguing report on the Greenpeace business model and philosophy has just been published by the Heartland Institute and can be downloaded here. The report was researched and written by Dr. Michael Connolly, Dr. Ronan Connolly and Dr. Imelda Connolly all of Ireland, Dr. Patrick Moore of Canada is one of the…

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…

An Assessment of the 4th National Climate Assessment

By Andy May The U.S. Fourth National Climate Assessment (NCA4) Volume II is out and generating a lot of discussion. Volume II, Impacts Risks and Adaptation in the United States to climate change can be downloaded here (Reidmiller, et al. 2018). Volume I, published last year, on the physical science behind the assessment is here (Wuebbles, et al. 2017). The mainstream…

We can eliminate fossil fuels, no problem!

By Andy May French President Macron has implemented a new fuel tax to discourage drivers from burning fossil fuels in their cars. The resulting higher fuel prices have caused more than 250,000 people to protest, with some rioting. Polls indicate that 62 percent of the population think that prioritizing man-made climate change over fuel prices…
