REMINDER TO DRONES: "Satellite data show no net warming for as long as such data have been collected, i.e., back to 1979. "

Satellite data show no net warming for as long as such data have been collected, i.e., back to 1979. 
Ocean measurements show no net warming over that period, either; the evidence for warming is based on land measurements. But the accuracy of land measurements depends on proper siting and maintenance of weather stations. One obvious factor is the urban heat island effect: many weather stations are located in cities, which grow warmer as more people and buildings accumulate. Thus, increasing temperatures at such stations may be measuring urban development rather than the climate. We all know that the urban heat island effect is real–”chance of frost in outlying areas”–yet the data that alarmists rely upon do not take it into account.
Apart from that broad issue, the siting and maintenance of weather stations is crucial to the accuracy of the data they generate. This was nicely illustrated in a recent post on Watts Up With That:
USE THE LINKS!

THERE'S AN OLD SAYING ABOUT DATA AND STATISTICS: SHIT IN, SHIT OUT.

USE THE LINKS TO SEE HOW ALARMISTS HAVE MISUSED DATA TO MAKE THEIR SOCIALIST CASE FOR CARBON TAXES AND SO-CALLED RENEWABLE/SUSTAINABLE/"GREEN" ENERGY.
