Well, years ago one could read about different opinions concerning global warming. I remember an article in the "SPIEGEL" (big german magazin) where a biologist gave lecture on the benefits of a warmer climate. There were discussions e.g. about the Sahara and wether this desert would become more green or more dry.
Gradually the tone changed from a discussion to alarmism. We all had to change behaviour, drive less, heat less, eat less, but pay more to save the world. The west supposedly is responsible for drought in other countries, causing people to starve and to flee, for rising sea levels and so on. Peak of hysteria was a professor (for music) in the Austrian city Graz who demanded death penalty for everbody who denied a global warming. Todesstrafe für Leugner des Klimawandels (german).
Most opposite views vanished from the mainstream media and moved to blogs, many of them pretty scientific and backed up by data. Sahara is becoming greener, the number of polar bears is greater than some years ago, and the global climate does not match in any way the predictions made by the state scientists, it´s cooler. The rise of the sea level(s) is slowly but steadily the same til the end of the last ice age. The only source who comes to a different conclusion is NASA with satelitet data. NASA claims a higher rise, but its one source against many monitoring stations around the globe. And as we know, EU want the rising sea level to grant asylum for refugees.
The PIK, the "Potsdamer Institut für Klimaforschung" (institute for climate research) is completely state ownend. Everbyody can read their work in the net, they provide two variations: The first is pretty scientific, they admit that reality does not match predictions. The second is a much shorter dossier distributed among politics and media. And in this dossier one can read that every measure has to be taken to prevent the climate becoming hell.
Furthermore, the AGW fabrication is utilized e.g. by Angel Merkel to increase state power. 500 billions Euro are the costs of the so called "Energiewende" so far. Meanwhile even some mainstream media question this waste of money, however a small number of journalists (the best, of course) left the state media and make their own blogs. Politicians talk about banning the gas driven cars within the next 13 years or so. I personally hope they make it earlier. Still too many people are not aware how fascism sneaks in, and what of manness is left in Europe might fortuntately end in an uprise when they come and take away your car
