we've been very slow to change because of a "wait and see" approach that just means the changes that need to be made will have to be made on a faster trajectory. The fact is the changes to our climate are no longer theoretical, they are very tangible now. Megadrought in the west along with massive expansion of forest fires, much higher humidity and rainfall in the southeast and midatlantic regions including the NYC area. Tangible rises in sea level that has lead to a rapid increase in sunny day flooding, in cities like Miami and Charleston. Evacuations of residents being made off barrier islands off the Lousiana coast because sea level rise has made those islands uninhabitable. Climate change causing the death of food crops in Central America resulting in mass migrations north. Much more soon to follow.
