The Chinese have pretty complete records of sunspots going back a couple thousand years.
Newton had pretty complete records as well.
His calculations were based on assumptions, just like the basis of global warming, since we don't have enough historical data to make a drop in a bucket.
And he was wrong.
You people who think the Earth started when you were born and will end when you die really make me laugh. The Sun is already billions of years old, and has billions of years to go, yet you folks think you've found the window of 200 years that defines the universe.
And it just happens to be during the time you are alive?
Weak human beings. With no concept of how insignificant you truly are to the universe.
What was Newton wrong about? His calculations work out just fine for ordinary, everyday events. If I were you, I'd forget about telling us what we think, but try to do a little more thinking of your own! Saying we think the earth started when we were born is TOTALLY WRONG. It's laughable that you could make such a statement and then call one of the greatest geniuses of all time, wrong!!! You have blinders on. The reason for looking at the last 200 years is because we're putting nmore CO2 into the atmosphere in days than all the volcanoes on earth do in a normal year! You, therefore, can't take the past as a template for the future, if uderlying conditions have changed.
