“the great (CO2) climate myth” … “a graphic fairy tale”

The CO2 theory has failed miserably, says Jim Steele (read it all at the link here), another environmental scientist who has had an AHA moment, in this latest post, citing a number of papers to prove his point. This is the second part of his expose on the inability of science to show a real warming caused by CO2. This is a short excerpt: Guest essay by Jim Steele,

Director emeritus Sierra Nevada Field Campus, San Francisco State University and author of Landscapes & Cycles: An Environmentalist’s Journey to Climate Skepticism

In part one, I wrote “In the simplest of terms, every study that has attributed the recent warming of the 1980s and 90s to rising CO2 has been based on the difference between their models’ reconstruction of “natural climate change” with their models’ output of “natural climate change plus CO2.” However the persistent failure of their models to reproduce how “natural climate changed before,” means any attribution of warming due to CO2 is at best unreliable and at worse a graphic fairy tale.” […]


In the Atlantic, poleward intrusions of warm water driven by natural cycles have similarly altered sea ice and the distribution of marine organisms. Satellite pictures (below) clearly show that the recent loss of winter Arctic ice has occurred along the pathway by which warmer waters enter the Barents Sea, deep inside the Arctic Circle, while simultaneously air temperatures far to the south remain cold enough to maintain a frozen Hudson Bay. Before those warm water intrusions facilitated the loss of sea ice, air temperatures in the 80s and 90s reported a slight cooling trend contradicting CO2 theory.12


Much of the warming in the Arctic in the 20s and 40s, as well as in recent decades was likely due to increased ventilation of ocean heat after sea ice was reduced by intruding warm water and the altered atmospheric circulation. A comparison of Danish Sea ice records from August 1937 with satellite pictures from August 2013, illustrate very similar losses of Arctic ice. As would be expected, a slightly greater proportion of thicker sea ice formed during the Little Ice Age would likely remain during the first warming event compared to recent decades. The slightly warmer Arctic temperatures of the recent decade can be attributed to a greater loss of thicker multiyear ice that is ventilating more ocean heat. But past performance never guarantees the future. Scientific opinions and predictions must be validated by experimentation or future observations. If indeed natural cycles are the real climate control knobs, the next 15 to 20 years will settled the debate. While alarmists predict total loss of ice by 2030 (and earlier predictions have already failed), believers in the power of natural cycles expect Arctic sea ice to rebound by 2030. Until then the science is far from settled. And claims that the science is settled just one more of the great climate myths. (Part 3 will look at the chimeras created by averaging and meta-analyses)
