'Let’s face it. The climate has never been more boring.'

Why you won’t see headlines as climate science enters the doldrums Guest post by Dr. Robert G. Brown, Physics Department of Duke University (elevated from a  comment on this thread: RSS Reaches Santer’s 17 Years) This (17 years) is a non-event, just as 15 and 16 years were non-events. Non-events do not make headlines. Other…

An Engineer's Take On Major Climate Change

Guest essay by Ronald D. Voisin Let’s examine, at a high and salient level, the positive-feedback Anthropogenic Global Warming, Green-House-Gas Heating Effect (AGW-GHGHE) with its supposed pivotal role for CO2. The thinking is that a small increase in atmospheric CO2 will trigger a large increase in atmospheric Green-House-Gas water vapor. And then the combination of…

Last three years prove AGW is not responsible for tornadoes

By Joseph D’Aleo, CCM Tuesday was an active severe weather day with 29 reported tornadoes (preliminary). Enlarged But for the season thus far, we are at the bottom end of the frequency as of the date. When it was active in 2011, the ignorant and opportunists blamed it on global warming. Last spring was very…

AGW Bombshell? A new paper shows statistical tests for global warming fails to find statistically significant anthropogenic forcing

From the journal Earth System Dynamics billed as “An Interactive Open Access Journal of the European Geosciences Union” comes this paper which suggests that the posited AGW forcing effects simply isn’t statistically significant in the observations, but other natural forcings are. “…We show that although these anthropogenic forcings share a common stochastic trend, this trend…

Support for the saturated greenhouse effect leaves the likelihood of AGW tipping points in the cold

From The Hockey Shtick, word of a new paper that supports Miskolczi’s theory of saturated greenhouse effect. We’ve seen this before, in the form of this graph. In 2006, Willis Eschenbach posted this graph on Climate Audit showing the logarithmic net downward IR forcing effect of carbon dioxide relative to atmospheric concentration: The flatter portion…

Abrupt changes in GHCN station-level temperature records contradict the anthropogenic global warming (AGW) claims.

Guest post by Jens Raunsø Jensen Preamble Inspired by a statement by Dr. Kevin Trenberth in the e-mails referred to as Climategate 2.0 (#3946 discussed here), it is hoped that climate scientists will have “an open enough mind to even consider” that the global warming of the 20th century could have occurred mainly as abrupt…
