I had an interesting train of thought.
When fuel oil/LP gas companies calculate how much energy was consumed on a particular day in order to calculate when customers will need a refill, they use degree days. The temperatures for each day are averaged hourly or more often rather than going by peaks and lows that might last for a short period. This gives a more accurate measurement than peak highs and lows.

If the climate is warming there should be a decline of daily heating degree averages days and an increase of cooling degree days averages.

After finding this EPA chart, I see that is the case but the number of cooling degree days is decreasing at a faster rate than cooling degree days are increasing.

What does this mean? Using my own crude method of averaging and projecting. the two averages will cross in the year 2170 at 2000 degree days which is less than the current averages of approx 2800.
