It turns out the weather data collecting isn't as accurate as we thought.

If you're sitting in prison you might get through this, it's long and from 2010.

Itâ€™s about data manipulation, been going on for well over a decade .

For consideration: The trend line is in blue

Wow so obvious to the ZEALOTS to pick out planet killing 2-4 degrees!
Cognitive Dissonance will fix that data for them

I didn't know most of the weather gathering data was at airports, lots of hot jet exhaust to skew temperature readings on a calm day.

And asphalt, and concrete and buildings, and the fact that most were in a field in the countryside to start with, but are now overrun by and surrounded by cities.

The last adjustment I have seen being universally applied to account for UHI is 0.2 degrees, whereas the measured UHI is commonly 10 to 50 times that much. But, even that adjustment only happens after all of the other adjustments the other way, which are rarely justified.

Some good points been made on weather stations in cities or at airports, I routinely watch temperatures in my car as I drive from the city to home and sometimes I will see a drop of 5 or 6 degrees C when I get out to the rural areaâ€™s. Concrete and pavement store a lot of heat, if this is the source of global warming then maybe itâ€™s time to rethink global warming.

The 0.2 degrees seems ridiculously low, but I'm not surprised because the placard carrying warmers are getting flawed data from somewhere.
