So if the meaning of the Trump brand is being the ultimate boss who has the power because he's so rich, the way you undermine that brand is by making him look like a puppet, and by showing that while he's playing gold and admiring his properties, it's actually other people making the key decisions and he doesn't really know what's going on.

It's certainly something we haven't seen before in terms of a fully commercial global brand - really a family of brands - not just Trump but also Ivanka, who has a sub-brand. We've never seen this before. We've had presidents in financial conflicts of interest before, but this phenomenon where a sitting president image avatar is out there selling golf courses and condominiums, even as he is in office and having the value of his personal brand inflated dramatically by fact of his being president, is new territory.

The task is clear: to create a culture of caretaking in which no one and nowhere is thrown away, in which the inherent value of people and all life is foundational.

I am convinced that climate change represents a historic opportunity on an even greater scale.

Terrorism doesn't just blow up buildings; it blasts every other issue off the political map. The spectre of terrorism - real and exaggerated - has become a shield of impunity, protecting governments around the world from scrutiny for their human rights abuses.

Why would we build as unequal a renewable energy sector as we have built a fossil fuel sector? The nice thing about renewables is they're everywhere, so you don't have to have monopoly control in the same way.

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