Just got this email, which I have to admit did put a smile on my face, even if bordering on spam:
John, you receive a much more entertaining variety of spam than I do.
But - that does not mean I'm jealous!
So (taking the Ruddiman Hypothesis to the next logical extreme), mankind built pyramids and megaliths worldwide in order to draw-down CO2 to keep global temps from rising high enough to melt the WAIS & trigger a much greater inundation than had already occurred? With the result being a sudden plateauing of global temp rise of the HCO...
Those Atlanteans & Lemurians really knew their sh*t...
A 5-kilometre high pyramid? That's something...
Consider that the Pyramid of Khufu at Giza is 147m high. It weighs something like 6 million tons.
Volume of a pyramid is 1/3 (L x L x H), so assuming the proportions stay the same, the weight of a 5,000m high pyramid would be on the order of 236 billion tonnes.
That would take quite a bit of resources. Yes, technically possible. Expensive, though.
The proposed expansion of the Olympic Dam mine, which will possibly make it the biggest open-cut mine in the world, will result in a peak extraction of 72 million tonnes of rock & ore per year, financed by the sale of 730,000 tonnes of copper, 19,000 tonnes of uranium oxide, and 25 tonnes of gold per year.
At that rate, it'd take the Olympic Dam operation a mere 3,279 years to build a 5-kilometre pyramid.
And then there are the impacts - how much stress on the local geology would be caused by that kind of weight?
What those numbers also highlight, for me, is the staggering amount of ice loss from Greenland each year. What was it last melt season - 500 billion tonnes? Wowsers!
