So why cripple our economies, ruin our lives, increase our food, transportation, and energy costs? Because of faith? Dire climate-related predictions from the church of climatology date back to the 1960s. Hundreds of them. Not a single one has ever come true. Not one. But we should believe it now?
Catastrophic changes happen over geologic time. There isn't a tax which can stop a natural process, so why bother?
Even if the stated sea level rise is accurate (0.12 inch per year), that isn't exactly a flash flood. Places like New Orleans demonstrate that you can live at or below sea level and manage it with engineering.
If it came down to it, we'd build or we'd move 1000 feet inland and be good for another 5,000 years.
The calamity and chicken little shit is overstated because it is about the money; always is.
