Context: The latest UN Environment Programme (UNEP) report, Limiting Overshoot, warns that global temperature rise cannot now be contained within the 1.5°C threshold of the Paris Climate Pact. The report calls for making the period of warming above 1.5°C “as small and short as possible”, while strengthening resilience and ensuring climate justice.

Key Concerns

1. 1.5°C threshold is increasingly difficult to achieve
   1. Global temperatures have breached the 1.5°C level more than once in the past five years.
   2. These temporary breaches indicate that the planet is approaching the long-term warming limit that the Paris Agreement sought to avoid.
2. Increasing frequency of climate disasters
   1. Heat waves in Europe, America and Australia and floods across parts of Asia demonstrate the growing intensity of climate impacts.
   2. The Nepal flash flood highlights how vulnerable communities are facing severe consequences in an increasingly unpredictable climate.
3. Risk of irreversible tipping points
   1. Every additional fraction of a degree increases the possibility of irreversible climate tipping points.
   2. Retreating glaciers and rising seas make it particularly difficult for vulnerable communities to build resilience.
4. Climate overshoot may become unavoidable
   1. UNEP’s best-case scenario projects warming peaking at around 1.8°C.
   2. However, 1.8°C should not be treated as a new target, but as a warning about the consequences that even strong climate action may have to confront.
5. Net-zero alone cannot immediately solve the problem
   1. Existing net-zero commitments cannot immediately neutralise the carbon already accumulated in the atmosphere.
   2. Climate action will therefore require both emission reduction and carbon removal.
6. Need for carbon removal
   1. Traditional methods such as increasing carbon sinks through forests need to be combined with emerging technologies capable of removing carbon from the atmosphere.
   2. However, the focus must remain on limiting emissions while using carbon removal to address accumulated greenhouse gases.

Ensuring Fair and Equitable Financing for Climate Damage

1. Unequal responsibility and unequal impact

1. Countries and communities that have contributed little to global warming often suffer disproportionately from climate disasters.
2. Nepal’s tragedy illustrates this injustice, as the country faces enormous reconstruction costs despite having little culpability for climate change.

2. Loss and Damage mechanism

1. The UNFCCC Loss and Damage Fund, created in 2022, was intended to support countries facing climate-induced losses.
2. However, the estimated cost of rebuilding Nepal is several times larger than the Fund’s corpus.

3. Institutional inadequacy

1. The Fund’s limited resources reveal the gap between the scale of climate-related losses and available international finance.
2. Its board has also not yet responded to the plea by several countries for an emergency meeting, highlighting the need for faster institutional action.

Way Forward

1. The global response must shift from focusing only on preventing warming to simultaneously managing the unavoidable impacts of climate change.
2. Climate institutions should develop rapid-response mechanisms for climate-induced disasters.
3. The Loss and Damage Fund needs adequate resources and faster decision-making.
4. Climate finance should follow the principle of climate justice, with greater responsibility placed on countries historically responsible for higher emissions.
5. Countries must continue ambitious mitigation efforts so that the overshoot above 1.5°C is as small and brief as possible.
6. Forests and other natural carbon sinks should be strengthened alongside responsible deployment of carbon-removal technologies.
7. Greater attention must be given to building the resilience of communities affected by retreating glaciers, rising seas, floods and extreme heat.

Conclusion: The climate challenge can no longer be viewed only as a race to remain below 1.5°C; it is also a challenge of managing climate risks and protecting vulnerable populations. A warming world therefore needs institutions that are rapid, adequately financed and guided by climate justice, while continuing every possible effort to minimise the scale and duration of climate overshoot.

Question: The world is entering a phase of unavoidable climate overshoot beyond the 1.5°C Paris threshold. In this context, discuss the need to reframe the global climate response around climate resilience, prompt institutions and climate justice.
