  Ecosystems around the world are at risk of critical transitions due to
increasing anthropogenic pressures and climate change. Yet it is unclear where
the risks are higher or where in the world ecosystems are more vulnerable. Here
I measure resilience of primary productivity proxies for marine and terrestrial
ecosystems globally. Up to 29% of global terrestrial ecosystem, and 24% marine
ones, show symptoms of resilience loss. These symptoms are shown in all biomes,
but Arctic tundra and boreal forest are the most affected, as well as the
Indian Ocean and Eastern Pacific. Although the results are likely an
underestimation, they enable the identification of risk areas as well as the
potential synchrony of some transitions, helping prioritize areas for
management interventions and conservation.
