It's CNN who really should hold Trump accountable. And because they are trading the short-term fix of increased ratings by focusing on Trump drama - and I'm not saying they shouldn't cover the Russian investigations, of course they should - but the blanket coverage, it's not about news values. It is about ratings. And it comes at a tremendous cost because Trump supporters are fully defended against this. As far as they're concerned, this is a vast conspiracy, it's fake news, it doesn't impact their daily lives, it makes them see Trump as a victim, which he wants to be seen as.

It doesn't have the ability to think rationally this economic model. It thinks like a drug addict: 'Where can I get my next fix?' It doesn't learn wisely. Any kind of measure of natural wisdom would be: you make a mistake, you correct it the next time around. But a drug addict feels terrible... and then says: 'I want more'. Unfortunately we have an economic model that thinks like a crack addict.

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.
