NEGOTIATING OUR PLACE AS THE EARTH TRANSFORMS
May 22, 2022 @ 11:00 am - 12:30 pm
Human activity has now resulted in crossing four of nine planetary boundaries. These are: 1) excess flows of nitrogen and phosphorus, 2) loss of diversity, 3) excess impact of novel entities and 4) excess variability of access to green water. In addition, the probability of staying below a 1.5C increase in average global temperature is now less than 10%. There are possible pathways for humans to adapt, within the limits of Earth Systems. Negotiating our place will require appropriate understanding and responses to real limits, in real time, in the context of increasing inequalities.
