Funny thing about your mom's theory, is that I don't ever recall the changing weather being one of the "Signs" that would (supposedly) indicate that we're living in the Last Days........I think the warning signs were: wars and signs of wars, pestilence, famine, nation rising agains nation, earthquakes, people having no natural affection, children being disobedient to parents..................where is there anything mentioned about the weather being part of this "Sign"???
Be that as it may, I do believe the weather's changing. I read a recent article in the National Geographic and it does indicate that all factors in the weather (floods, droughts, hurricanes, tornadoes, snow storms) are all getting more intense. I believe that this has something to do with all the pollution we've created over the last 150 years---it's screwing up the planet!!
I'm getting a new car next year (If I can save the money!) and I am seriously looking at getting one that is part electric......I'd save alot on gas and it cuts down on the amount of pollution...........
