One of the many things that climate change deniers don't understand is the non-linearity of climate. That is, as you change some of the factors that make climate warmer or colder, suddenly one factor has such influence on the other factors that the rate of change of the other factors suddenly increases or decreases.
Put some water in a pan with a lid. Turn the heat on high. As the water heats, vapor starts to come up around the lid. Nothing to worry about. Go into another room and forget about it. Suddenly you hear water splashing and hissing in the kitchen. The formation of steam within the water has gotten to the point where the water volume has increased beyond the volume of the pan. Oh, yes, your going into another room had nothing to do with the water boiling over. The water would have boiled over if you had stood daydreaming at the stove.
What will happen to our climate if the amount of CO2 released from the warming oceans reaches a "boiling point"?
Blow up a balloon so that the surface is very tight. Carefully and slowly push a nail against the surface of the balloon. The surface of the balloon will deform. Then you sneeze and push harder on the nail. Bang! Oh, yes, I forgot to remind you to wear safety glasses. Sorry! I originally thought of suggesting a pin, but depending on how full you blew up the balloon, the pin might burst the balloon as soon as you touch the balloon's surface.
At what point will we melt so many glaciers that the sun will heat ground that has not been heated in eons.
