Don't you know the Atlantic Ocean cooled once Panama connected North and South America?
The missing heat is melting ice, so figure it out. What happens when there is no ice to melt?
Do you know how much heat it takes to melt ice at 32 degrees F to 32 degrees F water?
Since you are so damned smart, what temperature will that 32 degree F water become if the same amount of heat is added after it melts?



Sure it is dumbdumb. Care to delineate the variables a little better there, currently your question is un-answerable based on your parameters. I thought you were a SUPER DUPER GENIUS? I would expect a SUPER DUPER GENIUS to know how to frame a proper scientific question.
The Atlantic Ocean cooled and the modern Gulf Stream started. The world changed and so did climate sensitivity. Now, because we send so much warmth and moisture to the north, we have Ice Ages, because of Milankovich Cycles.
What makes you think we want a cold world? We just want care taken in changing things when they are happening too rapidly. There are three major ice sheets on this planet and four if you count Patagonia, which is minor and melted in two. Wiping out all the coastal cities on Earth isn't a smart thing to do.
Now, if you want to pretend it can't happen, go ahead! I would bet in three years we are going to see major changes that will get the world's attention. Things like melting the arctic sea ice obviously didn't. When your ass is on the line, you'll care.
