Climate Science Challenge: Can someone smart tell me if this skeptical graph is accurate or fake? #climatechangehttps://twitter.com/mrmonks01/status/1109072818325598209 …

Wait, you mean the sun has an effect on climate? And the Earth's climate altered without humans?
No, he's saying using a graph with 500+ million years on the x-axis is a dumb argument. The worst argument against climate change ever is 'but muh climate always changed'. No shit. We don't care about dino weather, we care about the last 200 +/- years
Biggest difference: the continents were in a different configuration. Counting changes to the Andean Cordillera and the Himalayan/Tibetan plateau (IMO the biggest recent influences on actual climate), you can't really compare to anything older than 2-3 million years.
I also agree that the Earth's climate has continually altered before humanity existed. It would continue to do so even if humanity did not exist. The point being, however, is that atmospheric CO2 is not the driver of this change.
That is a perfectly valid argument. The fact that the world operated quite well, probably even better, when CO2 was much higher weakens the alarmist argument that CO2 is dangerous to the planet.
Incorrect. That only works if all other variables were similar when CO2 was higher. And they were not.
Disconnecting solar activity (the single source of all the world's power) from climate models is ridiculous. The sun's output alters. The last time Sol reached a grand solar minimum of sun spots, called the little ice age, the Tames froze solid.
The Sun was appreciably weaker hundreds of millions of years ago. But it was not appreciably weaker over the past 100 million years, &certainly not in the past 30-50 million years. CO2 was far higher than now very recently, geologically speaking. Too recently different Sun input
This is offcourse ignoring current understanding of the Sun and the correlation of sun spots with solar output. The last time we had a grand solar minimum, was 500 years ago, called the little ice age, and the Thames froze solid.
