Computer models set to predict worst case scenario always predict temperatures will rise.

You're suggesting that temperature rise is always the worst scenario? If you like. But obviously irrelevant. Computer models are set to understand the climate.

The calculation of about 3°C per doubling of CO2 predates computers. It was first calculated in the late 1800s. (https://www.rsc.org/images/Arrhenius1896_tcm18-173546.pdf)

Data collected often demonstrates that co2 follows temperature, not leading temperature.

Look at that graph again: https://www.climate.gov/media/11048

No it fucking doesn't. (Not with respect to the current warming. The glaciation periods end with about 5 or 6 thousand years of warming, co-incident with CO2 rise, initiated by CO2 rise for a few hundred years, setting off the positive feedback loop of increased CO2 driving increased temperature driving increased CO2.)

But that's not what's happening now, and it relies on the fact that CO2 causes warming.

It may be that co2 has nothing to do with the cause of global temperature at all.

Not unless it's not a greenhouse. Which it is.

Look at methane, a far greater risk of being a greenhouse gas which is rarely spoken of

It's not rarely spoken of. For instance, in the last few days:

We only produce about 3% of that which is around 12ppm.

I gave you the sources to show that we've produced over half the CO2 in the atmosphere between 1750 and 2020. And you still claim a fucking stupidly low figure like 3%?

Why? What do you hope to gain by repeating obvious bullshit without even attempting to back it up? You won't convince anyone else. Are you trying to convince yourself?

The sun doesn't heat the earth? Holy smokes! Quick, get out you co2 bathing suit next summer, I'm ready for a scorching!

It doesn't cause the current warming. Because there's be no trend in solar irradiance over the past 140 years, but there has been warming over the past 140 years. As you can see clearly from the graph at the link I gave you.

It was documented US government policy

Was it. Can you link me to this document?

Have you really been hiding under a rock this whole time or are you intentionally pretending that propaganda doesn't exist?

I never heard any propaganda claiming 100% effectiveness of masks or vaccines.

Any reference to flat earthers in a debate is an obvious derailment only intended to delegitimise any statements made by your opponent, the same strategy used in media and government tomshut down discussion when threatened.

You claimed that science is never settled. If it's not settled then there must be some arguments for the earth being flat. Or do you agree that science is sometimes settled?
