Foresight is no longer a luxury.

We’re not yet ready for what’s already happened to us, never mind what’s coming.

Almost everything about our lives, communities and economies was built to work well in the past, when conditions were different and the climate was more stable. Now we’re experiencing a discontinuity with that past, as the kinds of conditions we were used to get thrown into chaos.

This discontinuity challenges us to admit that our assumptions rest on shaky ground, that we can confidently predict much less than we thought we could — and know less about how to succeed now than we should. The climate crisis is a new era, not an issue.

I want to share with you stories of my own explorations.

After 30 years on the forefront of the planetary crisis—as an environmental journalist, the editor of the breakthrough sustainability publication Worldchanging, the creator of the best-selling Worldchanging books, and a climate futurist and advisor to over 100 institutions and companies—I’ve learned a lot about how to think at planetary scales.

Now I’m turning the insights I’ve gained from decades in the field towards the very edge of what we know about the world we now live in, and the new era that’s redefining it. These notes and short essays bring you the best of what I’ve found so far.
