how representative are arctic temp stations? they are usually at airports and close to the only pockets of people up there. not only that but these temps are smeared over thousands of kilometres in the averaging schemes used by GISS.
here is one station-
there are major problems taking temps in the middle of areas containing people in the arctic. then you add weird adjustments that drive down old readings by 1C and only correct for UGI by 0.05C (if it is considered urban enough for correction that is). then use those inflated readings to guestimate the temps for a 1000km in any direction.
do we have a reliable satellite that covers the arctic and antarctic? because I'm having a hard time believing the GISS temps are accurate.
think prop wash could affect anything? nahhhh
here is one station-
from the second half of this link- The North Atlantic heat is on | Watts Up With That?Remote communities in the Arctic are islands of anthropogenic warmth
These communities rely of aviation as a lifeline
The weather is measured at these airports, it is required for safety
Airports release huge amounts of waste heat, from exhaust, de-icing, terminal buildings, and even tarmac in the sun.
The majority of GHCN weather stations (used by NASA GISS) in the Arctic are at airports.
Remember Nuuk and Svalbarrds thermometers, and then ask Jim Hansen why NASA GISS, a space studies agency, doesnt use satellite data but instead relies upon a surface record that another division of NASA says likely has significant UHI effects that NASA GISS doesnt filter out sensibly (they only allow for 0.05°C downward adjustment).
And finally, can you really trust data from an organization that takes incoming data for that station and shifts it more than an entire degree C in the past, making a new trend? See the difference between raw (which really isnt raw, it has a scads of adjustments already from NOAA) compared to the GISS final output in this chart:
