What do you think that's going to prove?

Over time spans of billions of years, the output of the sun and the earth's climate has changed a lot. Yes we know that. Why do you think it is even a tiny bit relevant?

• Billions of years ago, the earth was a lifeless ball of molten rock, and there was no life on the planet, let alone human civilization.
• Hundreds of millions of years ago, the earth was a frozen wasteland where nothing more complicated than bacteria and undersea worms could survive.
• The last time the earth was four degrees hotter than it is now, 90% of the land area on earth was a baking hot desert where only lizards could survive.
• Even when the climate changes slowly, over tens of thousands of years, it still causes major disruption to natural systems.
• Short term climate change, even if it lasts only a few decades, causes massive disruption to human populations and nations. Empires and nations fall.
• Rapid climate change in a time frame of a century or less is absolutely unprecedented in all of human history.
