Some people think that observed changes are just the usual year-to-year variations. They remember the 1930's and 40's, when winters were so mild and dry that they rode scooters on the streets of Toronto. How would you respond to them?

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.
