Professor Emeritus of Geology at Western Washington University Debunks Climate Change Report — Point by Point

From the Climate Depot — July 18, 2014

Geologist Dr. Don Easterbrook, professor emeritus of geology at Western Washington University and author of 150 scientific journal articles and 10 books, including “Evidence Based Climate Science,” issued a point-by-point rebuttal to the new NOAA climate report and the media articles surrounding it.
Live Science: ‘Climate Records Shattered in 2013’ – By Becky Oskin, Senior Writer | LiveScience.com – July 18, 2014 – “The climate is changing more rapidly in today’s world than at any time in modern civilization,” said Thomas Karl, director of NOAA. (NOAA State Of The Climate In 2013: ‘Our Planet Is Becoming A Warmer Place’)

Climate Claim: “The planet ranged well outside of normal levels in 2013, hitting new records for greenhouse gases.”
Dr. Easterbrook comment: “NOT TRUE–CO2 levels for the past 500 million years were consistently greater than 3,000 ppm. 400ppm is abnormally low.

[Climate Depot Related Links: CO2 at 400ppm: ‘Scientists note that geologically speaking, the Earth is currently in a ‘CO2 famine’ and that the geologic record reveals that ice ages have occurred when CO2 was at 2000 ppm to as high as 8000 ppm. In addition, peer-reviewed studies have documented that there have been temperatures similar to the present day on Earth when carbon dioxide was up to twenty times higher than today’s levels’ – And, a peer-reviewed study this year found that the present day carbon dioxide level of 400 ppm was exceeded — without any human influence — 12,750 years ago when CO2 may have reached up to 425 ppm.]

Climate Claim: “The levels of carbon dioxide in Earth’s atmosphere at Mauna Loa Observatory in Hawaii hit 400 parts per million (ppm) for the first time in 2013. The worldwide average reached 395.3 ppm, a 2.8 ppm increase from 2012, NOAA reports. (Parts per million denotes the volume of a gas in the air; in this case, for every 1 million air molecules, 400 are carbon dioxide.)”
Dr. Easterbrook comment: “The CO2 composition of the atmosphere changed by only 0.004% since the onset of recent global warming (1978-2000).”

Climate Claim: “The major greenhouse gases all reached new record high values in 2013,” said Jessica Blunden, a climate scientist with ERT, Inc., and a NOAA contractor who helped write the report.
Dr. Easterbrook comment: “So what? If you double nothing (0.004%), you still have nothing!”
