Two Papers – “The Role Of Atmospheric Nuclear Explosions On The Stagnation Of Global Warming In The Mid 20th Century” by Fijii 2011″ And “Comets And Climate” By Zecca, Antonio and Luca Chiari 2009

I have been alerted to two very interesting papers [h/t to Paul Andrew Farquharson who is research student in the Ancient History department at Macquarie University in Australia studying the climate of the British Isles between AD 500 and 1500 from documentary sources – which all of us look forward to learning more about when he has completed his study!].

The first paper is

Fujii, Yoshiaki, 2011: The role of atmospheric nuclear explosions on the stagnation of global warming in the mid 20th century, Journal of Atmospheric and Solar-Terrestrial Physics Volume 73, Issues 5-6, April 2011, Pages 643-652

The abstract reads

“This study suggests that the cause of the stagnation in global warming in the mid 20th century was the atmospheric nuclear explosions detonated between 1945 and 1980. The estimated GST drop due to fine dust from the actual atmospheric nuclear explosions based on the published simulation results by other researchers (a single column model and Atmosphere-Ocean General Circulation Model) has served to explain the stagnation in global warming. Atmospheric nuclear explosions can be regarded as full-scale in situ tests for nuclear winter. The non-negligible amount of GST drop from the actual atmospheric explosions suggests that nuclear winter is not just a theory but has actually occurred, albeit on a small scale. The accuracy of the simulations of GST by IPCC would also be improved significantly by introducing the influence of fine dust from the actual atmospheric nuclear explosions into their climate models; thus, global warming behavior could be more accurately predicted.”

The second paper is

Zecca, Antonio and Luca Chiari, 2009: Comets and climate.  Journal of Atmospheric and Solar-Terrestrial Physics, Volume 71, Issues 17-18, December 2009, Pages 1766-1770

The abstract reads

“No connection between comets and climate has been proposed until now; here, we show that such a connection exists. We use a model to evaluate the shadowing effect due to cometary dust released by comet 1P/Halley in the inner solar system. We find that comet Halley has left a detectable fingerprint in the climate records of the last two millennia. The print shows up as a periodic cooling of the order of 0.08 °C. This temperature drop is comparable with other natural fluctuations. The finding will add a brick to our knowledge of the climate system and could allow to improve our predictive capacity of future climate.”
