Good for her. And that is typical. 6.2% of the weather stations out there are contaminated by over 5C! That is NOT a small number and it is having a HUGE impact on the global "average." The biggest factor is the overnight lows. In the cities...it just doesn't get as cold as it used to because radiative cooling can't do its business with all the concrete around.

YET...these brilliant scientist say this has NO or little impact. All I know is I would LOVE to ask Al Gore about it.

I recall one website that hat photos of the same weather stations over time. Tons of them. 1990 photo would show a weather station in the middle of a large grassy area. 2008 photo would show the same station with the grassy area now a paved parking area with a wall nearby, etc.
