GISS tells us that it was the hottest May on record. Just looking at that map makes me perspire. It must be wicked hot at the North Pole!
But wait a minute! The DMI record doesn’t look so hot in the Arctic.
What could be wrong? Could it be the fact that GISS has almost no coverage in the Arctic? We often hear the question”what if CO2 were pink?” Answer : it would still be almost invisible at 0.0004 concentration.
