Actually, the group of scientists who spread the climate catastrophe is very small. But as usual, they get their money from the state and are backed up by the media.
The rest keep their mouths shut - if you do not sing with the chorus, you are a climate-denier, you are evil and do not care about the future, if you still argue you are a nazi. Most facts against the so called CO2 catastrophe come from retired scientists.
Same with the so called "Energiewende" in Germany, those ridiculous windmills: I know many engineers in Germany, but not a single one who is convinced this "technology" could work. I mean its easy - everbody with just basic physical knowledge knows that it won´t work, wind energy (or solar panels) is not sufficient to deliver power for an industrialized country.
But meanwhile there is whole industry depending on state money, e.g. many people make money letting a parcel of land for rent for windmills. They will never vote for any party who would want to stop this madness.
