Or you can accept that disaster is coming, and begin to rethink what it means to have hope.
The whole essay can be dismantle with a single article: Trajectories of the Earth System in the Anthropocene, published in 2018 at PNAS by Will Steffen et al., https://www.pnas.org/content/115/33/8252
In the long run, it probably makes no difference how badly we overshoot two degrees
Potential interactions among the tipping elements of the Earth system could generate tipping cascades. The far we stay below the 2ºC, the less likely it will be the occurrence of tipping cascades.
Our atmosphere and oceans can absorb only so much heat before climate change, intensified by various feedback loops, spins completely out of control. The consensus among scientists and policy-makers is that we’ll pass this point of no return if the global mean temperature rises by more than two degrees Celsius (maybe a little more, but also maybe a little less).
Biogeophysical feedbacks have different tipping points. Some are in the range of the 2ºC limit, while others would occur at higher temperature anomalies. For example, a critical transition in the Atlantic Meridional Ocean Circulation (AMOC) is not expected beyond 3ºC
