New Study: German Mid-Sized E-Cars Produce Less CO2 Than Diesel Autos…After 364,000 Miles!

by P. Gosselin, September 19, 2018 in ClimateChangeDispatch

The German ADAC association, the equivalent of America’s AAA, carried a CO2 comparison for a variety e-autos and combustion engine cars. The results were very surprising, says German magazine Autobild here.

Today’s electric cars are being pushed as a clean and environmentally friendly alternative, while diesel and gasoline burning engines are being villainized as polluters and climate killer …

Les côtes de Flandre n’ont pas toujours été aussi paisibles qu’aujourd’hui, et je n’oublie pas le raz-de-marée du 31 janvier 1953 qui toucha les Pays-Bas et notre littoral, faisant plus de 1800 morts et des dégâts considérables. (photo : à Ostende).

Pêchés dans diverses chroniques et ouvrages (notamment “La Flandre mystérieuse” de Saint Hilaire), j’en ai fait une compilation qui n’a bien entendu aucune prétention scientifique ou historique, mais ces événements avaient laissé une trace dans la mémoire populaire, trace qui a hélas fortement tendance à s’effacer.

J’y ajoute quelques événements survenus en France et aux Pays-Bas, dont on peut raisonnablement penser au vu de leur localisation, qu’ils eurent des conséquences sur nos côtes

How constant is the “solar constant?”

by Andy May, September 19, 2018 in WUWT

The IPCC lowered their estimate of the impact of solar variability on the Earth’s climate from the already low value of 0.12 W/m2 (Watts per square-meter) given in their fourth report (AR4), to a still lower value of 0.05 W/m2 in the 2013 fifth report (AR5), the new value is illustrated in Figure 1. These are long term values, estimated for the 261-year period 1750-2011 and they apply to the “baseline” of the Schwabe ~11-year solar (or sunspot) cycle, which we will simply call the “solar cycle” in this post. The baseline of the solar cycle is the issue since the peaks are known to vary. The Sun’s output (total solar irradiance or “TSI”) is known to vary at all time scales (Kopp 2016), the question is by how much. The magnitude of short-term changes, less than 11 years, in solar output are known relatively accurately, to better than ±0.1 W/m2. But, the magnitude of solar variability over longer periods of time is poorly understood. Yet, small changes in solar output over long periods of time can affect the Earth’s climate in significant ways (Eddy 1976) and (Eddy 2009).

Statistical study of past temperature records suggest possible undetected natural climate forcing cycles

Godfrey Dack writes in with this:

Everyone will be familiar with the difficulty of listening to a conversation held with a friend in a crowded room with many other conversations going on at the same time. So it is with many fields of scientific investigation where it is difficult to tease a particular trend out from masses of data. In the first case, we could call the friend’s conversation ‘The Signal’, and the background conversations ‘The Noise’.

In looking at climate data, trends (the signal) can be graphically represented by a (generally) smooth curve, usually flanked by a range of experimentally predicted or actually measured values (the noise). Joining up every point on a graph of such data would give a jagged line which could be thought of as a combination of many alternating functions over a wide range of frequencies.
