No geological disasters happened in 1982 short of a 6.0 magnitude earthquake that killed 1,500 people in Dhamar, northern Yemen. In fact the celestial alignment allowed for NASA to pull off the Voyager 2 "grand tour" of the four outer gas giant planets from 1979 to 1989.
Jupiter contains more mass than all the other planets combined, and yet it is still less than 1 percent of the sun's mass. Therefore Jupiter's influence on the sun is inconsequential.
Alien astronomers could measure Jupiter's gravitational tug as an insignificant 270 mile-per-hour cyclic change in the sun's radial velocity over the planet's 12-year orbital period. Only if Jupiter was moved so close to the sun that its orbital period was measured in days, would some serious tidal effects be seen. This is observed with so-called "hot Jupiters," the exoplanet WASP-18 being the most extreme case.
Running an ephemeris forward in time, with the ease of throttling H.G. Wells' time machine, the next closest thing to a grand alignment comes in 2163 (shown above). Unless we have bombed ourselves back to pre-Columbian society by then, people in 2163 will be too science savvy to give this any thought. They will be bemused by historical accounts of the feared Jupiter Effect by their science-illiterate ancestors.
