Greta Thunberg's climate change speech

Yeah, that place out 'there'. Anything not really Cambodia related should go here.

It's physics. Simple physics.

CO2 is a greenhouse gas which absorbs infrared radiation send out by the Earth (heated up by the sun) and converts it into heat. Thus heating up the atmosphere. The more of it there is, the more heating up there is. No scientist is doubting this.

That's the simple basics.

After that there's al kind of feedback mechanisms in place, or there aren't, or we aren't sure (yet), making it more difficult, but the basics are just what they are... The basics of physics...

Obviously some scientists received bad grades at school and don’t understand simple physics.
No, you don't understand, or you don't want to understand. Do some research on (long wave) radiation and greenhouse gasses in any science book and you'll find the facts. If there's more CO2 in the atmosphere, there's more absorption of infrared radiation and more heat is generated in the atmosphere instead of the radiation dispersing into the universe. That's physics. No scientist will doubt that.

What some scientists do (try to) question is how much of the current temperature change can be attributed to the rising CO2 levels. Some scientist suggest other factors might influence temperatures as well (which is in itself true of course) and the effect of the CO2 is only a part of the current change.

That's what the discussion is about.

And that is precisely what i asked when i began to write in this topic. Read my first messages here. But you chose to play smart pants and take on mentoring tone to explain greenhouse effect.

If my tone was mentoring, I’m sorry. You asked for proof of more CO2 leading to higher temperatures. I provided you with the basic physics of CO2 And UV radiation and why more CO2 leads to higher temperatures if you just consider those two variables. If that’s playing smart pants, fine.

That doesn't explain why in many post-communist societies, after some years some people start to vote for communists again, the very same people that used to suffer from it. It seems to be a bit more complex.

The main reason is they were young back then. Human memory is created such that it tends to dismiss and forget what was bad, otherwise humans would go crazy from mental suffering. Most of us will remember our young age as best part of our lives no matter what -ism we lived under at that time.
Add to that physical disabilities and impotences of old age and there is no surprise that some feel nostalgic.
Some people also held positions of power and developed sort of entitlement to benefits that those positions were giving them.

lol

so tell us how we should live, hunter8

so that everyone gets what they need
and as many as possible get what they want (beyond mere materialism)

forever

ps the opposite of 'capitalism sucks' is not 'soviet'
