I have no proof, but as the climate has changed and mostly gotten warmer it seems like the summer heat takes longer and longer to dissipate from the ground and the water. We used to have snow at the end of November in PA. Now snow is only in January and February. It feels like winter is delayed a month because of our warmer summers. It also feels like spring is what keeps getting shorter. It warms slightly and then summer is full on again.
