I think it's because the air is now denser because of global cooling, creating more wind drag....

I've been commenting on that same premise, for quite some time.
I make the same drive, same car, same weather, year after year, from here to
Packwood, WA.
I've noted a drop in fuel economy, with all factors being exactly the same,
over a long period of time. Many, many trips.
I did also note, one of the reasons for my loss of economy, was, a loose
pre-chamber collar.
When that was fixed, I got back close to 30 mpg, where it had dropped to 28
or so.
But, it used to get 30-32.
I've kept good records, and have many trips, to average over different time
periods.
And, my car, in the last 10 years I've owned it, has gone from 185K to 240 K
in mileage, so, "wear" should not be a real factor, as far as changing
conditions.
by the way: '86 300 sdl.
To me, it started when "they" began reducing the sulfur content of
diesel......and, in winter, the "winterized" diesel, seems different, too,
when I got it.
