Yeah, that's possible, but very unlikely.

Even less likely, probably not anytime during your families future-history.

Any alien smart enough to travel through space and advanced enough to travel far enough to reach us isn't going to stop here. When was the last time you visited a primitive ant farm for the sake of eating ants?
I'm not arrogant enough to say we're the only intelligent life out there, but a species capable of interstellar space travel would be smart enough to steer the fuck clear of us.

This, actually, is the most sane of any of your paranoia. Our ecology and environment are, in fact, quite in danger. The slow in currents is connected to our rediculously high CO2 emissions which are tearing up the atmosphere and causing the globe to warm at a rate not seen since the last Ice Ages. (And if that's not clear to you what it means, it's really bad.)
The most unfortuneate part is that we continute to dump these toxins into the air, as they are a corner stone of every industrialized nation -- without which we would flounder. Regardless, even if we stopped ALL emissions RIGHT THIS SECOND, the residule damage will still be so bad that the temperature rise would cause enough ice to melt and enough currents to change that we'd lose many small islands and coastal towns, and obliterate inland areas due to increased weather conditions. (Seen the record breaking hurricane season the U.S. just had? That's not going to be a solo performance -- expect reruns in the years to come.)
THAT is something to be paranoid about.
Don't even get me started about the ways in which countries seek to emulate the U.S. and how that effect of capitalism and affluence are going to cause just as many problems.
