After they get back to us with those answers, here are several more questions:
How do you measure these things accurately?
What is the error percentage in the things you measure?
How do you compensate for measurements taken in the past using less accurate instruments?
How do you measure things that were not measured centuries ago?
What is your sample size and coverage area of ice cores around the world?
How can you be positive that the elements measured in ice cores are in the same quantities as when they were originally deposited, or has been some dissipation or contamination?
Where are the ice cores from the Sarah Dessert, SE USA and equatorial regions of the world?
What is your sample size and coverage area for tree ring measurements?
Where are your tree rings from the Arctic and Antarctic?
Why is it that when you measure sea-level rise it is different in different parts of the world, and always higher in Democrat-controlled coastal cities in the US?
Those same Democrat coastal cities are supposed to be underwater, years ago, according to Al Gore. He should have his head examined, maybe he was underwater and lost his brain cells.
And why did Obama pour millions into buying a coastal estate, that was supposed to be underwater. I mean, if it could still happen, why buy if your mansion will be a total loss? That's another man who needs his head examined.
