Abrupt Ecosystem Collapse
A new study in Nature (April 2020) casts a disturbing light on the prospects of abrupt ecosystem collapse. The report analyzes the probabilities of collapsing ecosystems en masse, and not simply the loss of individual species.

The paper states that a high percentage of species will be exposed to harmful climate conditions at about the same time, potentially leading to sudden and catastrophic die-offs of biodiversity. If high greenhouse gas emissions remain in place, abrupt events are forecast to begin before 2030 in tropical oceans and spread to tropical forests and temperate regions over time.
Without doubt, no nation is prepared for the consequences of collapsing ecosystems nor are they doing anything to avert it.
