Politics hates a vacuum. If it isn't filled with hope, someone will fill it with fear.

Because it is such a huge crisis, because it puts us on a firm science-based deadline, it's a once-in-a-century opportunity to build a better society and address raging inequality, create huge numbers of jobs, rebuild our public infrastructure.
