The initial statement argued that because organisms are "fine" with 1GW/sq km, they therefore should be fine with the additional heat of a datacenter. I disagreed with the conclusion, not the number. The second statement was that "OTOH, that 1GW drops to almost zero at night." It may be a literally true statement on its own, but it's misleading in response to a statement that absolute zero isn't a realistic basis for this discussion.
