The British insurance sector once did an analysis showing that at 3 degrees Celsius of global warming, 4 billion people could die — and at 2 degrees, 2 billion lives could be lost.
But that’s not even the full truth — it’s the minimum.

As social scientists, we understand there’s always a tipping point that moment when government policies must shift. The real question isn’t whether it exists, but when we cross it.

At 2°C of warming, over 1 billion people in the Global South will be displaced This is 20× more than after World War II.
This is not a prediction. It’s already unfolding.

I’ve spent eight years trying to get people to take part in civil disobedience.

Only 300 have gone to prison in that time. It’s not enough. Real change needs 500, maybe 1,000, willing to act — and to do it together, in a single month.

That’s how policy shifts. That’s how history turns.
