Global heating will hit at least 1.8C, UN warns, and there are ‘no good outcomes’
Summary
A United Nations report warns that global warming will reach at least 1.8°C above preindustrial levels, exceeding the Paris Agreement target of 1.5°C. This increase will cause worse extreme weather, melting glaciers, rising sea levels, loss of ecosystems, and threats to food, health, and economies worldwide.Key Facts
- The UN says it is now unavoidable to exceed 1.5°C of global warming.
- Heating could rise by 3°C by 2100, causing glaciers to lose over a quarter of their mass and sea levels to rise by up to 13 cm.
- Global food production might fall by up to 14% by 2050 without effective adaptation.
- Human health, water supplies, nature, cities, infrastructure, and economies face severe damage.
- Some environmental losses may be irreversible, forcing communities to relocate or change how they live.
- To limit damage, immediate and sustained cuts in greenhouse gas emissions are needed, along with efforts to remove carbon dioxide from the air.
