This debate is going nowhere. Climate relates to prevailing conditions in a region over time, not the extremes of weather whose unpredictability will always be with us.
There is no question that climate changes. It has changed over millions of years, long before the presence of Hono Sapien Sapiens on Earth, sometimes radically, [interglacial ice-ages] but for as long as this planet exists, ongoing, even if humanity ceased to use all fossil fuels tomorrow,
it wouldn't make one iota of difference, except to bring to a shuddering halt all development to the third world's economies.
