    more heat than can be dissipated, leading to an exacerbation of global warming?  In fact climate change is the elephant in the room that this very interesting article failed to address.

      ...civilization as a whole is apparently small compared to the heat generated by changing the way the atmosphere holds heat.

      IE, "global warming" is not the same thing as the heat generated by our direct actions, the climate changes are caused by gasses we've released into the atmosphere, not from the heat radiated into the environment by our devices.
