Because the temperature change is accelerating, the increase is concentrated towards the end of the period. But much more importantly, an increase of the global average temperature by X°C does not mean that it is more or less exactly X°C warmer everywhere every time. Changes are concentrated in time and space. I could also imagine quite well that the perception gets distorted. One may be much less likely to notice a change from 24°C plus or minus 1°C in summer than to notice that there is less time with snow because the temperature that used to be just below freezing point got pushed just slightly above it. Especially in places where the temperature used to hover just around freezing point for a long time, even a pretty small increase in temperature might easily shorten the perceived duration of winter as indicated by snow lying around by weeks. I also wonder whether growing up on itself makes a difference. Time speeds up as we grow older and a meter of snow looks certainly very different to me today than it look to me when I was a small child.
