Why it is warmer in the cities than surrounding rural areas.

This is also a major factor for higher recorded temperatures than decades past (not global warming).

There's a lot more concrete around than there was when those temp monitoring stations were built. Urban sprawl.

So, concrete sinks in a handful of major cities around the world...let's say, less than 0.001% of the planet's surface(?) affecting global temperatures?

:hmm:

I hope you realize that if you truly believe this, then you unequivocally accept man-made global warming. 😉

He's saying that the local temperature around some monitoring stations would go up as those areas became more developed / urban. The phenomenon causes localized areas, like cities, to get hotter. No one was suggesting it was global.

However, if a significant portion of these monitoring stations are now in fully-developed urban environments, they would record higher temperatures than they did 50 years ago. Someone looking at statistics would believe the global temperature was going up.

Exactly.

Tough crowd. 😛

I applaud you for trying to educate, Dennil. 😉

Well, I was aware of the effect but did not know the exact term or some details pertaining to the phenomenon. Thought I'd share after seeing it mentioned in a newspaper's online edition.

I still don't believe they taught this in grammar school way back when Dr. P was in grammar school. They probably even called it grammar school back then.
