From The Cliff Mass Weather Blog Last week we witnessed a major failure in science communication regarding the Northwest heatwave. A failure that misinformed you and millions of others, and a failure that highlighted glaring weaknesses in the media’s ability to cover important scientific issues. And it revealed the disappointing behavior of some members [...]
Original post of Ronald Stein can be viewed here Ancient tree stumps found under glaciers in Southeast Iceland are confirmed to be roughly 3,000 years old, RUV reports. A specialist believes the remarkably well-preserved stumps were part of a massive forest that disappeared after a long period of a warm climate. It is believed [...]
By Cliff Mass Reposted from The Cliff Mass Weather Blog During the past week, the Pacific Northwest experienced the most severe heat event of the past century. All-time high-temperature records were broken throughout the region, often by large margins. Many in the media, several local and national politicians, and some activist environmental scientists have [...]
In Part 1, we introduced the concepts of climate sensitivity to CO2, often called ECS or TCR. The IPCC prefers a TCR of about 1.8°C/2xCO2 (IPCC, 2013, p. 818). TCR is the short-term, century scale, response of surface temperature to a doubling of CO2, we abbreviate the units as “°C/2xCO2.” In these posts we review lower [...]
The IPCC claims, in their AR5 report, that ECS, the long-term temperature change due to doubling the atmospheric CO2 concentration or the “Equilibrium Climate Sensitivity,” likely lies between 1.5° and 4.5°C, and they provide no best estimate (IPCC, 2013, p. 85). But their average model computed ECS is 3.2°C/2xCO2. Here, “°C/2xCO2” is the temperature change [...]
Guest Post by Renee Hannon Introduction This post compares CO2 ice core measurements from Greenland to those from Antarctica over the last millennium. Paleoclimate studies typically use only Antarctic ice cores to evaluate past CO2 fluctuations. This is because the entire Greenland CO2 datasets were deemed unreliable due to chemical reactions with impurities in the ice and [...]
Thomas Wysmuller (right) with Rick Sanders and his wife Leonore in 2018. By Rick Sanders Thomas Wysmuller passed away on June 29, 2021. He was born into the famous Dutch Wijsmuller Zeesleeper family, and briefly sailed on Wijsmuller Tugs as a youth. Moving with his family to the United States, he studied Meteorology – even working [...]
Political debates over climate policy under the present zeitgeist of climate-change hysteria is like competing to see how many witches you can burn. This is how Professor William Happer described the situation after his recent lecture on the three greenhouse gases targeted by today's draconian national agricultural policies. Professor Happer gave this [...]
Greg Weiner has written a great essay in Law & Liberty, entitled: “Why We cannot Just ‘Follow the Science.‘” His point is that scientists and science are important, but relying only on “The Science” for decision making is both dangerous and foolish. Science is a methodology for proposing well-developed answers to questions about natural [...]
In the last post, I discussed the problems comparing modern instrumental global or hemispheric average temperatures to the past. Ocean temperature coverage was sparse and of poor quality prior to 2005. Prior to 1950, land (29% of the surface) measurements were also sparse and of poor quality. Only proxy temperatures are available before thermometers were [...]
