Scientists are well known to make up whatever, for banks and governments, especially when it is about issuing new tax backed bonds. Scientists just don't have the dexterity to cash in on it for themselves.
That's grade-A conspiracy nuttery, unsupported by any actual evidence.
Astronomy is not as statistical as environmental science.
It's quite similar. You can't run lab experiments with stars or dark matter, for example, but you can collect statistics on it, theorize on it, and run models for it. Yet nobody claims astronomy is a socialist plot. Go fig.
Whilst they may see some level of correlation between CO2 and temperature, and may run simulations, throwing parameters at things to invent explanations is a game, not science.
You're ignoring all the direct evidence for global warming, like stratospheric cooling, increasing backradiation and decreasing OLR in the GHG bands. Those are all smoking guns for human-caused global warming, and they don't use any models. No "natural cycles" theory explains such evidence, hence those "natural cycles" theories are wrong.
You didn't even know that evidence existed, because your cult didn't bother to inform you. There's no conspiracy. You're just poorly informed on the science.
You last statement is a good example of a religious deflection on known facts. But even forgetting that, try to keep any army fightworthy in today's England with only Roman red towels and no shirts and pants. Obvious, that climate is still colder. And then, the normal temperature of Earth has always been ~25C, several degrees higher than the current glaciation age.
Looks like somebody has been watching "300" too often, and thinks that Roman soldiers were like the Greeks in that movie, dressed only in red capes and speedos. Back in reality, the Romans, not being morons, were quite capable of dressing for colder weather.
