Most scams are absurd - so absurd that one wonders how anyone falls for them at all; yet if no one falls for them, how do the scammers make money?

I woke up one morning to an email from my friend Alex that said she'd had her bag stolen. Ordinarily, I'm quite quick on the uptake, but - maybe because of the way it was worded - I immediately replied, 'What??????' As soon as I hit send, I realised I was being scammed. But then they replied, and I thought, 'Well, why not?'

That's the worst health condition you can have, not being alive.

Crazy stuff happens when you start replying to scam emails. It's really difficult, and I highly recommend we do it.

Evolution, climate change, and the construction of the physical universe down to its atoms are processes that we measure in millions or billions of years.

The wave of new productive enterprises would provide opportunities to remedy the unjust distribution of environmental hazards among economic classes and racial and ethnic communities.

The earth's history over the past several million years is that for every 100,000 years, we go through a dramatic climatic cycle where we get 90,000 years of ice age and 10,000 years of a warm period. I think people today just have the expectation that we deserve a perfectly benign climate forever.

When people align around shared political, social, economic or environmental values, and take collective action, thinking and behavior that compromises the lives of millions of people around the world can truly change.
