The Big Momentum

Either hemisphere
It’s strange, late July,
Late January,

When the weather runs
Hotter and hotter,
Opposite the trend

Of the days getting
Shorter and shorter.
It never lasts long.

It will cool again,
And still cooler, if
Not as cool as once.

For a little while,
However, most years,
There’s a span of heat

Outracing the night,
As if less sunlight
Only warmed things up.

There are fanciful
Analogies there,
Or honest warnings.
