It's not lowering standards if it is an average departure according to an accepted benchmark. Even taking global warming out of the picture the climate has been changing since the beginning of the Earth, and most understand that the one constant in life is change, it should not expect the 30-year average to equal the 10-year average to equal the 200 year average. We have to give the audience some credit. Elder posters lived through winters of the past and would not benefit from being reminded at this cold departure is not the same as their childhood. The only audience that may gain knowledge are very new posters who have not lived through the past but what is the point in telling that audience? Are they going to care if they feel cold today but the grandparents felt colder?
Also it's not an artificial cold month if people feel cold and it is a negative departure from a 30-year average regardless of how fast it's warming.
Not sure what you mean about lowering standards to achieve a goal, could you elaborate please.
