Climate Change or Anachronism?

This drawing and verse appeared in the Hudson Daily Register in 1901 on June 21--the first day of summer.

Since the type is somewhat hard to read, here's a transcription:

My love and I along the strand

Now wander idly hand in hand,

And near encircled by a spell,

The sad old tale the waters tell.

I do not whisper nothings sweet

Nor pay my court in accents bold;

I do not swear undying love--

The reason--well, it's too blamed cold.
