UN Report Urges Limiting Climate Warming Beyond 1.5 Degrees
A new United Nations report says the world is unlikely to keep warming below 1.5°C.
Temperatures have already crossed that level for some periods in recent years.
This does not necessarily mean the planet will stay above it permanently, but it is a serious warning.
Heat waves and floods are already hurting people in many regions.
The report says every extra fraction of warming makes dangerous changes more likely.
It estimates that the best possible outcome may be warming of about 1.8°C.
This is a warning, not a new goal.
Countries would need to cut greenhouse gases and remove some carbon from the atmosphere to limit the damage.
The United Nations Environment Programme says limiting warming to 1.5°C is no longer possible.
Global temperatures have breached the 1.5°C threshold more than once in the past five years.
Heat waves, floods and Nepal’s flash flood show climate impacts entering uncharted territory.
The report urges making warming above 1.5°C as small and brief as possible.
Its best-case scenario projects warming peaking near 1.8°C, requiring emissions cuts and carbon removal.
- Who
- The United Nations Environment Programme and climate scientists are assessing the consequences of continued global warming.
- What
- A United Nations Environment Programme report concludes that keeping warming within the Paris Climate Pact’s 1.5°C threshold is no longer possible and urges limiting the resulting overshoot.
- When
- The report was released on Wednesday; temperatures have crossed 1.5°C more than once during the past five years.
- Where
- The effects described include heat waves in Europe, America and Australia, floods in parts of Asia, and a flash flood in Nepal.
- Why
- Every additional fraction of warming increases risks from irreversible tipping points, retreating glaciers, rising seas and reduced community resilience.
- Report
- United Nations Environment Programme study titled Limiting Overshoot
- Paris threshold
- 1.5°C of global temperature rise
- Best-case projection
- Warming peaking at about 1.8°C
- Recent breaches
- The 1.5°C level has been exceeded more than once in the past five years
- Recommended approach
- Make warming above 1.5°C as small and short as possible
- Carbon removal
- The report says action may require forests and technologies that remove carbon from the atmosphere
- Climate impacts
- Heat waves, floods, retreating glaciers and rising seas are identified as dangers
