It’s an odd sort of logic, when somebody presents NCDC, NOAA and NASA sources to show evidence for something, and all the warmists can say is “you are dismissing GISS and NOAA and NASA”, an obvious conundrum. As always, science trumps rhetoric, and we have plenty of science in this regard.
People who are actually experiencing the colder winters, especially farmers who raise livestock, and suppliers of heating oil and gas, they aren’t fooled by rhetoric or games with trends.
Winter trend from 1998-2013 shows clearly the large areas experiencing a cooling trend. Of course the warmer objects to a short term (15 years) trend when it shows cooling.
from 1995-2013 also shows the trend, but the warmer objects to a 18 year trend.
from 1992-2013 even still shows cooling winter trends, but a 21 period is too short.
from 1988-2013 a 25 year period.
There you see the cooling in Asia still showing up. But no longer the US. Except you can look at February (the coldest month of NH winters) and there it is again, a cooling trend for large parts of the US for February, from 1988.
Obviously from the severe cold this year, the trend is still happening for parts of the US, with colder winters, with more snow, becoming the norm.
If we see a 30 year trend for February, of colder temps and more snow, will it matter to the warmer? Not at all. If you showed a cooling trend for parts of the US that was 30 years long, it would be dismissed of course.
No, the only trend acceptable for claiming warmer winters, has to start in 1970, which is absurd to a scientific mind. Winters change rapidly in terms of both temperatures and snow, unlike the longer climate cycles.
So we have “the planet is warmer” being used to dismiss a clear winter trend, which just makes it much harder for anyone trying to retain credibility.
