Some of the critical climate issues that need to be headed off within the next 20 to 30 years if massive impacts are to be avoided:
- The loss of all summer sea ice in the Arctic;
- The large-scale triggering of the melt of peri-Arctic permafrost (likely irreversible once started);
- The mobilisation of the melt of Arctic ocean permafrost and clathrates;
- The melt, destabilisation and loss of the West Antarctic Ice Sheet;
- The destruction of the bulk of the world's coral reefs;
- The acidification of the Arctic Ocean and the Southern Ocean to the point where organisms with calcified shells cannot survive;
- The flooding and disruption of the small island states;
- The spread of the Sahara into Southern Europe and the Middle East and the large-scale extension of many desert systems globally;
- The large-scale conversion of the Amazon forest to grasslands;
- A severe ramping up of extreme weather events;
- Extreme food shortages;
- Very large-scale refugee movements; and
- Serious risk of climate wars.
