If the heat sink really is bigger than they thought, then Global Warming must have decreased more,
because of remaining heat from the sink.
The global temperature stopped increasing over 18 years ago. A big heatsink will dampen the temperature changes slowly. So an even global temperature which is being warmed by the heat sink, means that the warming has to have decreased.
In other words: A big heat sink is a sign of global cooling, not warming. And the lack of people pointing out this rather obvious physical connection, is a sign that they are charlatans, or quite stupid. And yes, I am a real physicist, not a political appointee pretending to be one.
