So we are left with a stark choice: allow climate disruption to change everything about our world, or change pretty much everything about our economy to avoid that fate. But we need to be very clear: because of our decades of collective denial, no gradual, incremental options are now available to us.

In a world where profit is consistently put before both people and the planet, climate economics has everything to do with ethics and morality.

Trump's act of construction is not building a building. It is building the meaning of the name "Trump." Because his revenue really comes from selling his name to people who do actually build things. They pay enormous sums of money for the supposed privilege of being associated with the name Trump or the name Ivanka, because of that image construction. That's why it seemed like a good idea for Trump to run for president in the first place.

When it comes to paying contractors, the sky is the limit; when it comes to financing the basic functions of the state, the coffers are empty.

The widespread abuse of prisoners is a virtually foolproof indication that politicians are trying to impose a system--whether political, religious or economic--that is rejected by large numbers of the people they are ruling. Just as ecologists define ecosystems by the presence of certain "indicator species" of plants and birds, torture is an indicator species of a regime that is engaged in a deeply anti-democratic project, even if that regime happens to have come to power through elections.

So we are left with a stark choice: allow climate disruption to change everything about our world, or change pretty much everything about our economy to avoid that fate. But we need to be very clear: because of our decades of collective denial, no gradual, incremental options are now available to us.

It is eminently possible to have a market-based economy that requires no such brutality and demands no such ideological purity. A free market in consumer products can coexist with free public health care, with public schools, with a large segment of the economy -- like a national oil company -- held in state hands. It's equally possible to require corporations to pay decent wages, to respect the right of workers to form unions, and for governments to tax and redistribute wealth so that the sharp inequalities that mark the corporatist state are reduced. Markets need not be fundamentalist.
