4 Billion Dead
There are no words
We’ve passed +1.5°C above pre-industrial temperatures. +2.4°C is now unstoppable. The image below is from the Planetary Solvency report by the Institute and Faculty of Actuaries, the UK’s only chartered professional body dedicated to educating, developing, and regulating actuaries based both in the UK and internationally. Recent projections show we’re on track to reach +3.0°C by 2050, a level of heat that puts billions of lives at risk from un-liveable heat, agricultural collapse, social upheaval, and war.

Why This Matters
Climate breakdown is often discussed in abstract terms: degrees, targets, timelines. But the consequences are human, uneven, and already unfolding.
This project does not ask for belief, loyalty, or ideology.
It asks for attention.
Each image is a reminder that behind every projection and every dataset are lives at risk — real people, in real places, right now.
