Making the link between climate change and other ecological emergencies


It was great to see so many people at the Planetary Boundaries workshop on Thursday 20th February.

As part of our Tipping Points campaign, we looked at climate change in the wider context of 8 other Planetary Boundaries. We had a lively discussion and learned a lot.

A group of internationally renowned scientists have identified 9 hard-wired boundaries in the Earth system that can be identified scientifically.

Humans must learn to respect these boundaries to protect the capacity of the biosphere to continue to operate as a self-regulating system which remains reliably stable and hospitable to our species and many others.

Crossing these boundaries could generate abrupt or irreversible environmental changes.

The workshop gave us a chance to begin to understand the science behind the Planetary Boundaries concept.


Data showed us how we already face four interrelated ecological emergencies: biodiversity, the nitrogen cycle, climate change and ocean acidification.

We finished by exploring how our society could respond to these challenges, including some controversial policies discussed by Mark Lynas in his book The God Species.

For background on the Planetary boundaries concept, please download the Planetary boundaries workshop notes.

We’ll be doing more on our Tipping points campaign in the coming months, including work around our Tipping Point declaration ‘Tipping Point Declaration’- an eight point statement about the causes and impacts of climate change both now and in the future.

If you would like to sign up to ‘The Tipping Point Declaration’ please email us your name, house number and postcode. We will then complete a paper copy of the Declaration for you. We will post a copy of this to your local councillor and to your local MP. We respect your privacy. Your name and address will not be displayed publicly at any time.
