so far youre all kind of wrong.
climate change and global warming refer to two different phenomenons happening in our earths atmosphere. climate change obviously refers to the general changing climate to specific areas or regions,..the climate is constantly changing everywhere in the world and always has been, yes most places are getting warmer and some places the climate and weather is getting more severe, not necessarily colder, but different and more wintery weather patterns than normal. (mid-atlantic coast these past few years for example)
Overall the average temperature on earth is steadily increasing (getting warmer). But when you look at a graph of the average earths temperature it starts to spike dramatically right around the time of the industrial revolution when we started to rely on fossil fuels for basically everything,
99.9% of scientist world wide agree that there is a direct correlation to the dramatic rise in the earths average temperature and the start of us as a world burning fossil fuels (resulting in CO2 emissions) which basically pile up in the earths atmosphere so when sunlight gets transferred to infrared heat, less heat can escape the atmosphere). This is what is commonly referred to as global warming.
Yes global warming is happening and very much exists and is real. If you think other and disagree with 99% of scientists than you are probably a fox news watching republican or just a straight up retard...most likely both.
as far as it affecting skiing, it depends on where you are. there have been many record breaking snowfalls all over north american ski resorts in the past 10 years or so, also the north east has been experiencing record low snowfall amounts recently while the mid atlantic has been getting hammered
kind of long i know, possibly not all entirely 100% accurate but i just kind of spitballed the whole thing, ive written a few papers on this exact topic in some college classes so im somewhat farmilliar with it but certainly not claiming to be any kind of meteorologist or weather/climate expert. feel free to add or make corrections if you feel you are more qualified to explain this to people that are less informed about
