In my understanding, climate collapse occurs when a rapid and irreversible disruption of planetary climate systems takes place, disrupting the stability of local and global ecosystems and leading to significant biological, physical and societal upheaval. Such collapses can manifest in the form of abrupt and catastrophic events, like sea level rise and extreme weather events, or as a persistent erosion of the climate's stability, such as significant ocean acidification and desertification. Evidence continues to mount that human-induced climate change is the primary driver of climate collapse. It is therefore paramount that we act swiftly and decisively in order to mitigate the most devastating consequences.
