IF TEMPERATURES RISE BY 2C RATHER THAN 1.5C
- Global sea levels will be 10cm higher by 2100
- The Arctic Ocean will be free of sea ice in summer once per decade, not once per century
- More than 99 per cent of coral reefs will decline, compared to 70 to 90 per cent
HOW TO LIMIT GLOBAL WARMING TO 1.5C
- The report warns the world is well off track to meet a 1.5C limit
- Rapid and far-reaching transitions are needed in land, energy, industry, buildings, transport and cities
- Global net human-caused emissions of carbon dioxide (CO2) to fall by about 45 per cent from 2010 levels by 2030
- Any remaining CO2 emissions must be balanced by removing CO2 from the atmosphere
- Renewables should supply 70 to 80 per cent of electricity by 2050
