WUWT is hosting a guest post by Reed Coray. If his thought experiment is as I read it then it is an epic fail. Continue reading

New Paper “Parameterization Of Instantaneous Global Horizontal Irradiance At The Surface. Part II: Cloudy-Sky Component” By Sun Et Al 2012
There is yet another paper that documents the lack of skill in multi-decadal global climate models to skillfully predict climate conditions in the coming years. This paper involves the question of accuracy lost when radiation parameterizations are used at time intervals that are long compared to other physical processes in the models. Continue reading
Further Confirmation Of The Misinterpretation Of Miniumum Land Surface Temperature Trends By NCDC, CRU, GISS And BEST As Part Of A Diagnostic Of Global Warming
In post Guest Post By Richard McNider On The New JGR – Atmosphere Article “Response And Sensitivity Of The Nocturnal Boundary Layer Over Land To Added Longwave Radiative Forcing” Dick McNider reported in our new paper Continue reading
Medieval Warm Period found in 120 proxies. Plus Roman era was similar to early 20th Century.
Two major proxy studies, larger than ever, were released in April and June 2012. They show that the Medieval Warm Period (MWP) existed, and was similar to current temperatures. Continue reading
Roy W. Spencer: JGR Paper Submitted: Modeling Ocean Warming Since 1955
This is meant to be just a heads up that we have submitted a paper to Journal of Geophysical Research (JGR) which I think is quite significant. We used a 1D forcing-feedback-diffusion model of ocean temperature change to 2,000 meters depth to explain ocean temperature variations measured since 1955. Continue reading
Roger Pielke Sr.: Two More Papers On the Complexity Of Climate Science
In response to the post A Research Paper “C4 Grasses Prosper As Carbon Dioxide Eliminates Desiccation In Warmed Semi-Arid Grassland” By Morgan Et Al 2011 I was alerted to the two papers below. Continue reading
Forest fires, wood-burning stoves may have stronger climate impacts than previously thought
Well look at that. We’re getting to the point there isn’t much room left for CO2-forced warming at all after accounting for black soot, brown soot, land use change, urban heat islands, cloud cover changes and solar effects. Does carbon dioxide have any net effect? We’re still not sure. Continue reading
Two More Papers On The Important Role Of Regional Circulations on Climate Including Extreme Weather Events
The importance of regional atmospheric and ocean circulations has been a major theme in my posts on the possible role of humans on the climate system; e.g. see What is the Importance to Climate of Heterogeneous Spatial Trends in Tropospheric Temperatures? Continue reading
IPCC Rejects Political Claim By ‘New Scientist’
THE UN Intergovernmental Panel on Climate Change has defended itself against charges by New Scientist that it was “putting politics before science” by imposing geographical and even gender quotas in the selection of its contributing scientists. Continue reading
New Paper “Climate Physics, Feedbacks, And Reductionism (And When Does Reductionism go Too Far?)” By Dick Lindzen
I was alerted to an important, informative new paper by Dick Lindzen on the issue of climate. The paper is R.S. Lindzen, 2102: Climate physics, feedbacks, and reductionism (and when does reductionism go too far?). Eur. Phys. J. Plus (2012) 127: 52 DOI 10.1140/epjp/i2012-12052-8. Continue reading
Clive Hamilton: Science under siege
“Most climate researchers expect to work quietly in a lab, not deal with an angry and threatening public.“
Why yes, Clive, that is true but perpetrating fraud, lying to the public for personal advancement and constantly threatening the public with imaginary/fabricated boogeymen tends to get them angry and the more effervescent lash out. Continue reading
Den Tandt: Blind faith won’t make gaps in climate science go away
Here’s the irony about Canada’s two-decade, shambolic, inept, half-hearted and contradictory response to the incontrovertible fact that the planet’s surface climate has, over the past 150 years, warmed: It mirrors uncertainty about the predictive ability of climate science. In a way, the chaos of our response epitomizes the gaps in what we know. Our failure is, in fact, a direct consequence of those gaps. Continue reading
Historical Storm Trends in France
With respect to extreme weather events, Dezileau et al. (2011) write that the major question of the day is: “are they linked to global warming or are they part of natural climate variability?” Continue reading

Climate Regulation and Dimethylsulfide (DMS)
Dimethylsulfide or DMS is an organosulfur compound with the formula (CH3)2S. It is the most abundant biologically-produced sulfur compound to be found in the atmosphere, being emitted to the air primarily by marine phytoplankton. P Continue reading
Hockey Schtick: New paper contradicts a tenet of global warming theory
A paper published today in Atmospheric Chemistry and Physics finds that clouds located in the stratosphere over the poles act to cool the stratosphere by adiabatic cooling, which is the cooling of air parcels as they rise and expand, rather than by ‘trapping heat’ below the clouds resulting in ‘radiative cooling’ of the stratosphere above.

Pierre Gosselin: New PNAS Paper Shows Light Causes Atmospheric Aerosols To Grow – Impact Our Climate
Scientists keep finding major knowledge gaps in their “science-is-settled” field of climatology. Continue reading
Hockey Schtick: New paper finds water vapor feedback is strongly negative
The IPCC manufactures climate alarm by assuming CO2 controls water vapor to produce a runaway positive feedback system. Continue reading

Climate Change Impacts Human Evolution
Most scientists agree that the Earth is undergoing significant climate change, partly due to the greenhouse gases produced when fossil fuels like oil, gas and coal are burned. Continue reading

Emissions cut hiatus slows work to limit warming
Reluctance to raise ambitions to cut greenhouse gas emissions due to economic constraints is threatening progress towards limiting global warming, delegates at United Nations’ climate talks in Germany warned on Monday. Continue reading
