Newest Climate Model Still Useless, German Scientist Says. And: Green Energy Turning Into An Ecological Disaster

One of the fathers of the German environmental movement, Prof. Fritz Vahrenholt, comments on models, Friday school strikes and the environmental destruction by green energies.
===============================

Ladies and Gentlemen,

New climate model is useless

Over 80(!) authors, led by Jean Christophe Golaz of Lawrence Livermore National Laboratory, have recently developed a new climate model (produced for the upcoming IPCC 6th Assessment Report). While so far the models have been parameterized on the basis of a period of pronounced warming (mostly between 1976 and 2005), the current work of Golaz et al (2019) takes a different approach: the pre-industrial conditions around 1850 were taken as the starting point.

Until around 1955 the model did well with the “tuning” of 1850, even though it did not reflect the warming of around 0.4°C between 1925 and 1945. After that, however, it literally goes out of control. We see a reduction in the temperature level of up to 0.5°C until about 1996, then a warming rate of over 0.5°C/decade. The observations do not show this:

The paper also explains how this happens: The aerosols (they cool by shading the solar radiation) have far too great an effect in the model and the climate sensitivity to greenhouse gases is also clearly too high. Björn Stevens of the Max Planck Institute for Meteorology Hamburg (MPI) also addresses the problem that models compensate too high a sensitivity to greenhouse gases by too much (negative) aerosol forcing.

Natural variability not taken into account

It seems to be a fundamental problem of all models that do not sufficiently take natural variability into account and want to explain temperature development solely by anthropogenic influences. In the end, Golaz et al. (2019) comes to the conclusion that both the (negative) aerosol propulsion and climate sensitivity to greenhouse gases (especially CO2) must be reduced in models in order to simulate the recent past from 1960 onwards with the necessary precision.

“Little to do with reality”

For the declared purpose (the development of scenarios up to 2100 – i.e. the next 80 years), even the latest “sophisticated” models turn out to be unsuitable. They predict a catastrophic development because of faulty modeling that has little to do with the reality of the last 50 years.

Greta and the world of models

Greta and her German followers derive their demands for an immediate end to our lifestyle from this very false model world. In fact, climate researchers who are familiar with the unreliability of climate models should steer the children’s crusade to a sensible direction, for example with reference to the contribution by Jochem Marotzke, who recently came to the conclusion in Spiegel that “our remaining CO2 budget for the 1.5 degree target is probably at least twice as large as we thought it would be“.

Yet the very same Marotzke now supports the Fridays for Future demands for a short-term coal phase-out in Germany by 2030, bot in China where the annual CO2 increase is about as high as Germany’s total emissions. And Marotzke is assisted by climate researchers Claussen, Schellnhuber, Rahmstorf, Latif, Mosbrugger, Stocker and Anders Levermann (this is the one who claimed in the scientific committee of the German Bundestag that CO2 is an angled molecule and therefore a greenhouse gas).

He probably missed too many chemistry classes on Friday as well.

New headlines on environmentally friendly alternatives

The number of wind turbines is to be doubled to tripled in the course of the Energiewende [transition to green energies] energy revolution, one wind turbine every 2.7 km. But now there are new warnings about the environmental impact.

According to a DLR model analysis carried out at the end of 2018, flying insects (e.g. the admiral, ladybirds) seek high rapid air currents shortly before laying their eggs in order to be carried by the wind to distant breeding sites. The currents are above 60 -100 m and hit a rotor area of 200 million m². An air throughput of 10 million km³, which is more than ten times the German airspace (up to 200 m height), will be sucked in by the rotors.

1200 tonnes of insects to be destroyed

1200 tons of insects will be destroyed by the rotors, which is 1200 billion insects. One of the authors estimates that this corresponds to the size of the insects destroyed by 40 million cars. Remarkably, the decline of flying insects and the expansion of wind turbines over a total height of 100 m to 200 m coincided 15 years ago. Coincidence? We do not know.

“Shut down wind turbines from April to October”!

The scientists demand a shut down the wind turbines from April to October at temperatures above 10°C. For our parliamentarians in the German Bundestag: The Federal Agency for Nature Conservation has so far rejected an investigation.

Green Energies’ “Silent Spring”

Maybe our striking students should take a look at this topic in class. Because if the fear turns out to be true, it’s not just about flying insects, but also about the whole ecosystem. Silent Spring – without chemicals – simply through the transition to0 green energies without technology assessment. It started with corn crops and biogas and ends with wind turbines.
