Dependence of Earth’s Thermal Radiation on Five Most Abundant Greenhouse Gases,

W.A.Wijngaarden (York Uni., Canada) and W. Happer (Princeton Uni.,USA) have published a remarkable paper on the influence of doubling the actual concentrations of greenhouse gases (GHG). The paper is very math-heavy and not easy to read, but 2 conclusions are important:

1. at current concentrations the forcings from all GHG are saturated, so...
2. doubling the concentrations of 5 GHG increases the forcings only by a few percent in the cloud-free atmosphere

James Randi, the master of the skeptical scientists and magician extraordinaire passed away 92 years old. Read the New York times obituary of this outstanding debunker of scientific and paranormal fraud, and read here what he had to say on climate change.

A new paper by Margaritelli et al. published in Nature - Science Reports (link) shows that the Mediterranean surface water temperature were during the Roman Warm Period about 2°C warmer than today! CO2 levels are assumed < 280 ppm at these times, which should make you think again. The authors conclude that during the Roman Optimum " ... developed the greatest ancient civilization of all time, the Roman one. We hypothesise the relevance that these climate conditions may had in the expansion of the Roman Empire and its collapse with the general development of colder conditions." (the original figure left has been edited by me by adding text and arrows).

Tell this the climate alarmists of today!

A very important new paper by Kramm et al. shows how historic papers from 1850 to 1910 evaluate zonal yearly average temperatures, and how they differ to the "consensus" values.
The authors conclude that the historic data do not show global warming during the last 100 years, as the older temperatures are higher than those given by the consensus climatology.

A very interesting paper by Bohleber et al. published in "Climate of the Past". From 2 ice core drillings done at the Colle Gnifetti (Monte Rosa) they deduce from the observed dust layers a temperature profile going back to 800 AD. And surely, the MWP (Medieval Warm Period) and the LIA (Little Ice Age) are there, all periods which have been belittled in the TAR of the IPCC (because old warming periods not caused by CO2 do not fit into the narrative!).

Outstanding article by Thea Dorn in the German ZEIT online "Nicht predigen sollt ihr, sondern forschen!"
"...Wissenschaftler haben durch Zweifel zu glänzen, nicht durch Rechthaberei...Eine der tragischsten Taten, die eine Demokratie begehen kann, ist Selbstunterwerfung unter die rigiden Handlungsvorschriften einer klerikal auftretenden Naturwissenschaft aus Angst vor dem Unterworfensein unter die Macht der Natur..."

Impact des EnR: Watch this very interesting video of the presentation of Marc Jancovici on the impact of renewable energy in France (French spoken). I do not agree with Jancovici on his appreciation of climate urgency, but as an engineer he has very clear and solid arguments concerning intermittent renewables and nuclear energy.
Especially interesting is his graph showing that  the price of "renewable" electricity risks becoming negative above a certain percentage of produced wind-power w.r. to the installed capacity (a more and more frequent situation in Germany, for instance).
 

Open letter to the KNAW (Royal Netherlands Academy of Arts and Sciences) by Prof. Guus Berkhout, founder of CLINTEL (Climate Intelligence Foundation), asking for not excluding scientists with alternative views.
" What concerns me about this embarrassing state of affairs is that science is being misused to provide spurious justification for wishful climate policy and that the scientific establishment is looking the other way...The IPCC was supposed to be a scientific initiative – I was a strong supporter of it myself. However, it has emerged as a political organisation that abuses science."

"On Behalf of Environmentalists I apologize for the Climate Scare"

writes well known environmentalist and climate activist Michael Shellenberger. In his list of what to do note this:

- 100% renewables would require increasing the land use for energy from today's 0.5% to 50%
- the most important thing for reducing air pollution and carbon emissions is moving from wood to coal to petroleum to natural gas to uranium

Prof. Richard Lindzen has published a very interesting paper "An oversimplified picture of the climate behavior based on a single process can lead to distorted conclusions".

ICE SAINTS

The Frost Saints or Ice Saints days ("Eisheiligentage") are cooling since 1998 at meteoLCD, and still longer in Germany. Did you hear about that in the media? More on the blog.

Research done at a geothermal power station in Iceland has shown that gazeous CO2 dissolved in water which is injected into underground basalt rocks mineralizes in just 2 years, and such will be safely stored away indefinitely without any risk of leakage as they may exist in traditional CCS (Carbon Capture and Storage) systems..

The ongoing solar minimum continues to increase the cosmic radiation at the altitudes of transatlantic flights (20000 - 40000 feet). The hourly dose may reach about 3800nSv, to be compared to the 80nSv common at ground level (look at our radioactive measurements!)

Read this interesting article on HALEU (high-assay, low enriched) nuclear fuel from disused ERBII reactor and its planned use in the Oklo Aurora micro-reactor at INL (Idaho National Laboratory). HALEU is seen by many as the fuel for small reactors and as a tool to recup energy from spent nuclear fuel.

The Oklo Aurora reactor is a reactor running on metallic fuel, without any liquid circuits.

The German philosoph Gunnar KAISER asks 12 very logical, but easy to understand questions regarding climate and its variation; he asks these questions to the famous TV physics professor Harald Lesch. Watch the YouTube video (German spoken, about 17 minutes) and just try to follow the logic!

Look at these graphs which show a similar 60-year sinus-pattern for the velocity of warming and the change in ocean heat content. Note also that the velocity of warming seems to be uncorrelated to the yearly CO2 emissions (here gigaton C/year, right axis, red plot).

Clive BEST has a good article on the baseline problem of temperature series, and why the choice of the baseline period is influencing the concordance (or discordance) between models and observational data: "It is the model projections which change dramatically when using different baselines. One should always bear this in mind whenever  an ensemble of models seem to perfectly  match the data well."
