New paper blames about half of global warming on weather station data homogenization

The solution to Glowbull Warming is so easy! If we could lock up Algore and put a ball gag on him that would eliminate the other half. lol

Exactly!

I always ask global warming folks why they think they know, within 1 degree even, the average world temperature in 1850. How many stations were there in the Yukon in 1850? How many in the Amazon? How many reading taken from the middle of the Pacific in 1850? How accurate were the gauges, and who thinks some guy in Alaska in the winter of 1850 was getting readings accurate to 1 degree, let alone 0.01 degree?

They just reply, “Science has proved...”

Plus we have continued reductions of stations in the northern hemisphere, and many relocated within UHC (urban heat centers), placed next to air conditioning outlets, sitting on airport tarmacs, etc..
I know most here at this point know these facts, but just in case we have some beginners that are just getting on board.

Exactly. More to the point, the whole idea of "average world temperature" is useless. What's useful, from a human point of view, is measuring the degree to which temperatures diverge from what is optimal for humans, and where.

The assumption here is that (1) there is warming, and (2) warming is always bad. If winters become less harsh in the Yukon and Siberia, and temps stay much the same elsewhere, then that would be considered "global warming", but it would be a GOOD thing.

As George Carlin said in one of his routines, “it’s 82 degrees at the airport. Which is stupid, because no one lives at the airport.”

Tell GISS Hansen that. :)
