We don't really even know if the temperatures are actually going up or if so by how much. There is so much urban heat island effect distorting the numbers that it is hard to say with say with any accuracy.

Of course temperature measuring equipment like this doesn't help.

How about a hot parking lot as a place to measure temperature?

Lots more

I think knowledge about temperature is sufficient. The level of uncertainty is not high enough to support much continued debate about AGW except among specialists who really want to get down to the nitty gritty. At the level involved in policy decisions - it’s nonsense.
