What will cause people to finally think: 'Gee, the climate is changing'

Like ‘grist’ writer, David Roberts, I too wonder what will finally cause people to say “Gee, the climate is changing”.

Will it be droughts, floods, fires, unprecedented storms, rising sea levels, food shortages or noticeable disruption to our usually benign temperatures?

Roberts punts on rising seas levels as it will affect directly the lives of millions and that in turn will impact of the lives of millions more.

He discusses his ideas in a story headed: “Could flooding finally wake Americans up to the climate crisis?”
