I live next to Lake Tahoe and I can tell you that there is more snowfall already this winter than all of last winter. I think El Nino is responsible. Nobody denies climate change.
Climate change has been happening for billions of years. Read a bit about paleoclimatology; it could answer some of your questions.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
