Biodiversity

Changing climate will require species to move to zones where the climate suits their survival. Many habitats will be split up by movement of the more mobile species away while the plants they depend on cannot move quickly enough. This will lead to greatly damaged or lost habitats and accelerating “weed” problems. Habitats impacted most drastically will be complex habitats with long evolutionary pasts (e.g. mountain habitats, rainforests, coral reefs) fragile species with small geographical ranges, etc. All groups of biodiversity will be impacted including:

   sea life        plants         animals

Impact type                     2050                             2100                          2300

                                   Low        High                Low        High             Low        High

Loss of habitat      40% gone  60%                60%        90%
