The Planetary Pulse

We have expanded our Pulse family of interactive tools with the Planetary Pulse.

A free unofficial interactive guide to the nine planetary boundaries, the limits that keep Earth in the safe, stable state civilisation grew up in. Built on the Planetary Health Check 2026, the latest scientific assessment of the state of the planet, it turns the dense 120-page report into something you can read in simple English and use in a lesson. 

You can access it here: https://169to1.org/the-planetary-pulse

Every boundary has a live slider that starts where the world is today, so students can drag it into the green or the red and see what crossing it would mean, with each figure traced back to the science. Written to be clear for any reader, and ready for teaching in and out of the classroom for 11-16 year olds.

It works as the evidence half of a pair with the 'How to Live on Earth' Lesson Companion: Where the film gives the human story, the Pulse reading of 120-page report gives the instruments behind it. The Activities tab carries a ready-to-use classroom activity and a field activity for each of the nine boundaries, every one mapped to the EU's GreenComp sustainability framework and to the SDG targets it helps prove. Alongside the boundaries you can see how they connect as one Earth system, the tipping points to watch for, the report's spotlights, and what can still be done.
