Distribution maps of Biosphere and Cryosphere tipping elements

This dataset contains a collection of sources that mark the geographical areas of regions/elements/biomes of the Biosphere and the Cryosphere identified as tipping elements on various temporal and spatial scales by the Global Tipping Points Report 2023 (https://global-tipping-points.org) based on:
- Armstrong McKay, Sakschewski, Roman-Cuesta et al., In prep.
- Winkelmann, Steinert, Armstrong McKay et al., In prep.

Below you find the data sources for the collection of this dataset. Note that the biosphere data sources provide more biomes than listed here, as only those identified as tipping element are selected here. For the full datasets, including non-tipping biomes, please refer to the original sources listed below.
