I really feel that appeal to the appearence of various natural phenomena discloses continuing regard for a God of natural forces; a primitive concept of God.
The human race originally, it would seem, worshipped all sorts of things: rocks, trees, fire, wind, the sun, you name it. Worshipping things, especially those it couldn't understand, was even more pronounced: lightening, thunder, volcanoes, and earthquakes. We don't so much worship these things anymore as we tend to use them as ancillary items in certain forms of worship, especially superstitious, cultic worship.
The plain fact is that as the earth cools off, as it has been doing for millions of years, there will be less convective pressures in the mantle and thus less volcanoes, and less tectonic movement, thus less earthquakes. It's just the nature of things. One day in the unforseeable future, the earth will be cool enough so that no plate tectonic-type movement will occur at all. And perhaps this will happen before San Francisco is opposite Juneau .
However, earthquakes and such are phenomena that were once attributed to the action of God, not plate tectonics, so sure enough, when God is ready to kill off the human race (except for Jay-Dubs, of course) he is scheduled to engage in all sorts of these kinds of phenomena.
IMO, this and so many other of our philosophical/religious problems arise from an inability to shed the dead skin of olden, primitive and savage concepts of who and what God is.
Getting to your question, no, I don't personally believe that these are the "last days." Nor do I believe that there is any such thing as any last days for life on this planet, not in the sense you mean. There may be the last days of our slow progression toward that species of spiritual maturity that will elevate our thinking to realize that God is not the savage spirit-demon of Horeb who is just a cut above a Chemosh or a Baal, but instead is a loving father who does not desire the death of any one of his children (even the misguided ones like the Jay-Dubs, who lust after the violent destruction of all who don't share their quaint beliefs).

Where it is a duty to worship the Sun you can be sure that a study of the laws of heat is a crime.
