...results are unambiguous.
406.55 ppm, week ending December 10, 2017, at the Mauna Loa Carbon Dioxide Observatory
Here's a picture of what's happening, in case you don't get it, of the annual increases of carbon dioxide from Mauna Loa :

This is the measurement of carbon dioxide in the planetary atmosphere, increases in which are accelerating, no decelerating, all the useless bullshit about Germany notwithstanding.
I have no use whatsoever for the German energy program. It's a waste of money and time, and is, in fact, counter productive.
If it were working, this news item would not have appeared last month:
As Germany hosts green summit, an energy firm is razing a nearby forest
They're destroying an old growth forest to dig coal.
I don't give a shit, in general, about journalistic crap however and am unimpressed by decade after decade after decade of "percent talk" about what happened on some sunny windy day. It's illiterate.
I've been hearing this bull here for more than 15 years, and elsewhere, much longer. I'm not drunk on wishful thinking. I'm soberly facing some hard cold reality.
The only amount of dangerous fossil fuels that should be utilized in percent terms is um, zero percent, not just on windy sunny days when journalists somewhere are drooling all over themselves, but every day, every night, every damned second.
The mere fact that this useless scheme to provide so called "renewable energy" is so damned popular is probably a function of the fact that one cannot get a journalism degree on this planet if one has passed an introductory college level science course.
I read the primary scientific literature, a lot of it, and the conclusion I've come to have 30 years of nearly obsessive reading is that the German, and by extension the world approach to addressing climate change as expressed in the faith based worship of the toxic, expensive and unsustainable solar and wind industries is not merely ill advised but is, in fact, a crime against all future generations.
The German program is a very, very, very, very, very bad joke.
Enjoy the coming work week.
