Yes global warming and cooling is a cycle over millions of years and eventually our earth may see an end as we know it. The global warming and cooling cycle as we have seen over the past 75 years or so is nothing compared to the entire cycle that will come. The contributing of mankind does affect it but one needs to laugh at that when considering the entire cycle. that will come and go over millions of years.
btw...Salt doesn't need rubbers anymore as he is too old to begin with plus they probably won't fit over his shoes.
