Fascinating, completely interesting!
I have a question: When I boil water on the stove, the hot water at the bottom rises. What is keeping the hot water under the lake from rising? The weight and mass of the cold water? That can't hold forever, can it? What keeps the temperature of the water from evening out, from the hot water below to the frigid water on top?

And this seems like it would have a "pressure cooker" effect--the volume of water expands as it heats, and with the cold water "lid" holding it down, if it keeps heating up, something has to give...
Just a question, hope it's not too silly...

the eruption of Toba in Sumatra about 74,000 years ago may have caused global cooling of from three to five degrees Celsius, and perhaps as much as 10 degC during growing seasons... Toba is a supervolcano with a 110km caldera. When it last exploded 74,000 years ago, the worldwide population of homo sapiens took a massive hit. It's estimated to have declined to just 7,000 to 9,000 individuals worldwide. Since one of these things goes off on average two times every 100,000 years, these things are 1,000 times as frequent as an asteroid hit.
