The Global Warming Sceptic  (2020-202x)

STATEMENT:
This page does not represent an official position of the Lycée Classique de Diekirch or the Ministry of Education on climate change and global warming. The official position of the Ministry of Environment of Luxembourg can be found here. If you do not want to read the following links and discussions, please go back!

Please take a step back, and stay cool for a moment. Shut your ears off from the deafening cries and shouts of the global warming advocates, and sharpen your mind. Try to answer the questions outlined in the papers given hereafter, and be open for good reasoning: these pages might make you think again, and wonder, if the mobiles of all these climate catastrophers are pure .... 

Working for clean air and an unpolluted atmosphere is a laudable aim, but forgetting to compare the magnitude of man-made pollutants to the natural sources, or having an absolute faith in measurement data of often dubious origin, is unscientific at least, and foolish certainly. The climate  is "the changing state of the atmosphere", so do not expect a steady state situation. Do not forget either that the sun is the engine which drives everything, and that the output of that engine is in constant change!

There is no Climate Emergency

800 scientists wrote a letter to the UN Secretary-General with the message that there is no climate emergency.They write that "warming is far slower as predicted", that "climate policy must respect scientific and economic realities" and that "our advice to political leaders is that science should strive for a significantly better understanding of the climate system, while politics should focus on minimizing potential climate damage by prioritizing adaption strategies based on proven and affordable technologies"

Decadal Changes of the Reflected Solar Radiation and the Earth Energy Imbalance

 

Steven DeWitte et al. (RMI and Uni. Brussels)have published a very interesting paper on the changes of the imbalance of the Earth's radiative budget during the period 2010-2018. Despite an increasing concentration of atmospheric greenhouse gases this imbalance has not increased (as one would expect) but ***decreased***, in correlation with the changes in the heat content of the oceans. They also find that the influence of changes in global sea ice to the amount of reflected solar radiation is small.
We’ve just had the best decade in human history. Seriously. For the coming days of joy and appeasement, read this optimistic comment of Dr. Matt Ridley in The Spectator. "A modern irony is that many green policies advocated now would actually reverse the trend towards using less stuff....Environmental opposition to nuclear power has hindered the generating system that needs the least land, least fuel and least steel or concrete per megawatt...Technology has put us on a path to a cleaner, greener planet. We don’t need to veer off in a new direction. If we do, we risk retarding progress.".

The Toxic Rhetoric of Climate Change Excellent text by Prof. Judith Curry from Climate etc. (14-Dec_2019):
 
" ...Over the past century, there has been a 99% decline in the death toll from natural disasters, during the same period that the global population quadrupled....
... We still don’t have a realistic assessment of how a warmer climate will impact us and whether it is ‘dangerous.’ ...
... We have not only oversimplified the problem of climate change, but we have also oversimplified its ‘solution’".
Has global warming already arrived? An interesting paper by Varotsos and Efstathiou (Climate Research Group, Uni Athens) published in the Journal of Atmospheric and Solar-Terrestrial Physics:  The authors analyze satellite data and find that the observed temperature field in the global troposphere and lower stratosphere is different from what global warming theory says. They conclude that
"...it is not possible to reliably support the view of the presence of global warming in the sense of an enhanced greenhouse effect due to human activities".
Capacity factors for wind and solar in the UK (2002-2018) Here are the capacity factors for UK wind and solar production from 2002 to 2018, and notice how solar PV remains practically constant at an appalling low figure of 10% (to be compared to nuclear or gas at ~90%). More here.

Interview with Prof. Hans von Storch Prof. Hans von Storch (Institut f. Meteorlogie, Uni Hamburg) gave a resounding interview (in German) to FOCUS online: On the climate protests of Fridays for Future: "Wenn es sich in der Forderung nach symbolischen Akten erschöpft, bringt es nichts...Panik ist ein miserabler Ratgeber..."
On (some) climate researchers: "Sie sollten nur nicht anfangen zu sagen, dass ihr Problem viel wichtiger ist als andere Probleme..." Read also here.
Climate limits and timelines Read the comments by Prof. Judith Curry.
Podcast Dr. Stefan Kröpelin (Uni Köln), one of the best desert specialists, has been interviewed by 2 journalists of the Rheinische Post (in German). Listen to this exciting podcast (46 minutes) where he resists to accept continuous suggestions to scary climate change:

International Energy Outlook 2019 ... published by the EIA (US Energy Information Administration).
Consumption of petroleum and other liquid fuels is expected to rise in 2050 from actual 50 to about 80 million barrels/day in non-OECD countries, and remain more or less stable at 45 in OECD countries; so total world consumption would be about 130 million barrels/day in 2050 (about 100 in 2018).
Observational data from tide-gauges

Even if some alarmist (German) climatists speak of accelerating global sea-level rise, this is not so. Read this comment and this report from Prof. Judith Curry. Click here for observational data from tide-gauges (Prof. Ole Humlum's climate4you web site) for many locations. The level measured by tide-gauges (relative sea-level) is what counts for eventual adaptation measures!German (Wismar) and Dutch (Den Helder) tide gauges show an unspectacular linear trend of about 1.41 mm/y since 1860 (i.e. the end of the Little Ice Age cooling).

Interruption of two decades of Jakobshavn Isbrae acceleration and thinning as regional ocean cools In these times where media news of Arctic and NH glacier meltdown might drive you into depression, recover to sanity by reading this paper by Khazendar et al, published by Nature GeoScience (paywalled, full version easy to find). This glacier is the biggest contributor to Greenland ice loss. Since 2016 its retreat and thinning has stopped: it is now thickening and advancing!
The cause is the well-documented North Atlantic cooling, itself probably influenced by the AMO (Atlantic Multidecadal Oscillation).
Propagation of Error and the Reliability of Temperature Projections

This paper by Dr. Patrick Frank (SLAC, Princeton University) did much furore and lead to many lively discussions, also among climate realists. Applying standard text-book error/uncertainty calculations, he shows that the temperature projections by the climate models can not be trusted, as the small predicted increase is buried in a huge uncertainty (because these models ignore/do not properly account for cloud forcing uncertainty).
