Yes, they have been extrapolating temps for areas where they had no direct measurement. However, as they stated, one should use the NCDC measurements for those areas, if very accurate measurements are desired.
Yet, for all of Watts yapping, none of this changes the fact that the warming continues, and differant agencies have better accuracy in some places than others, depending on the methods used.
Another item concerning Watts. He is not a meteorologist. He is a fraud in that department.

Watts grew up around Cincinnati, Ohio and reportedly attended Purdue University[1], studying Electrical Engineering and Meteorology.[2]. Watts's "About" page mentions neither his Purdue attendance nor whether he graduated. [3]. Watts has not been willing to say whether he graduated.[4]

Credentials held
Watts holds an American Meteorological Society Seal of Approval (a discontinued credential that does not require a bachelor's or higher degree in atmospheric science or meteorology from an accredited college/university)[6] with a status of "retired".[7]

Some online lists incorrectly refer to Watts as "AMS Certified"[8], but this is incorrect; the American Meteorological Society reserves its "AMS Certified" designation for its Certified Broadcast Meteorologists and Certified Consulting Meteorologists[9], and Watts posesses neither certification.[
