Yes - but why isn't the heat island effect taken into account? We have more buildings, concrete, blacktop, vehicles and solar panels than ever before - all which absorb and release heat and way less grass, trees and open unpaved areas. So while it is indeed warmer its also deceptive. If I take my house and spray foam the entire structure and then use the same amount of BTU's to heat it as before my average indoor temperature will have increased. I have read many articles over the years about improper placement of thermometers which violate the "good practices" set forth by NWS. So with all that in mind as well as the 30 year average being used its really a no brainer as to why its warmer.
