I think skiing's already pretty well-known. Are you trying to say that it will be a popular sport? If so, probably not because most people either don't have access to the mountains or the money to do it.
if skiing doesnt become popular it will have nothing to do with global warming. And even if it starts to take place theres crazy good snow guns that can make snow at like 0 degrees.
i think it is getting bigger for sure. just look at the number of newschoolers you see on a hill any given day(for me anyway). i remember when no one skied and it was embarasing if someone found out you skied instead of boarded. now skiers clame the title with pride
it'll never be big like basketball baseball or football because we arent ghetto enough and none of the athletes get paid 50 million dollars a year. this is a good thing though
