IPCC AR7 delay: pressure mounts for climate report

The Intergovernmental Panel on Climate Change (IPCC) is facing pressure to delay the publication of its seventh assessment report (AR7)1. This proposed postponement could significantly impact global climate action and the UK's net-zero ambitions. Originally scheduled for 2028 to inform the COP33 summit, the push to delay it until 2029 highlights growing tensions between geopolitical interests and the urgent need for scientific guidance. This situation underscores why the UK must accelerate its clean energy transition, demonstrating that proactive national action can build a future with abundant energy, even amidst global political challenges.

The IPCC's role in global climate science

Understanding the Intergovernmental Panel on climate change

The IPCC stands as the world's leading authority on climate science. It is the UN-convened body of the world’s leading climate scientists. Its primary role is to provide governments with comprehensive, objective scientific information relevant to understanding climate change, its natural, political, and economic impacts, and risk and response options. The IPCC does not conduct its own research but synthesises thousands of scientific papers from around the globe, making its reports the most credible and widely accepted scientific basis for climate policy.

The significance of assessment reports like AR7

IPCC assessment reports are crucial for informing global climate policy and negotiations. These multi-volume reports, released every few years, summarise the state of climate science, outline future climate scenarios, and assess options for mitigation and adaptation. The seventh assessment report (AR7) is particularly significant as it was originally scheduled for 2028 to directly inform the COP33 summit, a critical juncture for reviewing global progress under the Paris Agreement. These reports provide the scientific bedrock upon which nations, including the UK, build their climate strategies and set their targets.

The proposed delay of the AR7 report

Why a delay is being advocated

Pressure is mounting to delay the publication of the AR7 report from its original 2028 timeline to 2029. The primary argument put forward by proponents of the delay is to allow more input from developing countries. This perspective suggests that an extended timeline would enable a broader and more equitable representation of scientific contributions and perspectives from nations that may have fewer resources to dedicate to such extensive reporting processes.

Key nations pushing for postponement

Several influential nations are advocating for this postponement. These include major petro-states and large developing countries such as Saudi Arabia, Russia, India, and China. Their collective push for a delay signals a complex interplay of national interests, economic considerations, and differing views on the pace and equity of global climate action.

Arguments for and against the delay

Perspectives from petro-states and major developing countries

The nations advocating for the delay, including Saudi Arabia, Russia, India, and China, often frame their request around the principle of equity. They argue that a longer preparation period would ensure a more inclusive process, allowing scientists and experts from developing countries to contribute more thoroughly to the report. This, they suggest, would lead to a more representative and robust scientific assessment that better reflects the diverse realities and challenges faced by all nations.

Concerns from vulnerable nations and the High ambition Coalition

In stark contrast, vulnerable nations and the High Ambition Coalition strongly oppose any delay. They fear that postponing the AR7 report could undermine urgent global climate action and jeopardise the goals of the Paris Agreement. For these nations, timely access to the latest scientific findings is paramount for effective climate change negotiations and policy-making.

Jiwoh Emmanuel Abdulai, the minister of environment for Sierra Leone, further emphasised this, stating: "The Paris agreement can only deliver on its promise if the best available science continues to guide climate change negotiations."

The role of equity in climate change negotiations

The debate surrounding the AR7 delay highlights deep-seated tensions regarding equity in climate change negotiations. While the call for greater input from developing countries is a valid concern, critics suggest that this argument is being "weaponised" by some larger developing nations to serve other interests. Claudio Angelo of the Observatório do Clima in Brazil found it "extremely concerning the way the structural issue of equity is being weaponised by some big developing countries." This suggests that while equity is a critical principle, its application in this context is viewed by some as a means to potentially slow down the pace of global climate action rather than genuinely enhance inclusivity.

Impact on UK climate policy and global targets

How the delay could affect UK net-zero ambitions

The UK's commitment to net-zero emissions by 2050 is fundamentally underpinned by scientific assessments like those produced by the IPCC. Delays in these reports can influence the pace and ambition of international climate negotiations, which in turn affect the UK's diplomatic efforts and domestic climate policy reviews. Without the most up-to-date scientific consensus, there's a risk that policy decisions could be based on older data, potentially slowing down the urgency of action required to meet ambitious targets. The UK's climate policy framework often references the latest available climate science to justify its targets and measures, making timely reports essential.

The UK's stance in international climate summits like COP33

The AR7 report was specifically intended to inform the COP33 summit. A delay could leave a critical gap in the scientific evidence available to negotiators, potentially weakening the resolve for stronger commitments. For the UK, which aims to be a leader in global climate action, this could complicate its diplomatic efforts to push for higher ambition and robust agreements at international forums. The absence of fresh, comprehensive scientific backing might make it harder to galvanise collective action among nations.

Maintaining momentum for the Paris agreement

The Paris Agreement relies on a cycle of increasing ambition, guided by the best available science. A delay in the AR7 report could disrupt this cycle, making it more challenging to conduct a thorough global stocktake - the process by which countries assess their collective progress towards the Agreement's long-term goals. As Jiwoh Emmanuel Abdulai noted, the Paris Agreement's promise hinges on science guiding negotiations. Weakening this scientific foundation, even temporarily, risks losing crucial momentum in the fight against climate breakdown.

Proactive steps for a resilient climate future

Accelerating the UK's clean energy transition

The IPCC AR7 delay underscores that waiting for external consensus or political processes to drive urgent climate action is a risk. The UK can lead by accelerating its own clean energy transition, demonstrating that a future with abundant, clean energy is achievable through national initiative. This aligns with the principle of "never settling" for the status quo or for a scarcity mindset. By investing in renewable energy infrastructure, smart grid technologies, and energy efficiency, the UK can build resilience against global political hurdles.

Empowering individuals and the private sector

Beyond government action, empowering individuals and the private sector is crucial. Engaged UK adults, concerned about climate policy, can contribute to solutions by adopting cleaner energy options, improving home energy efficiency, and supporting businesses committed to sustainability. The private sector, driven by innovation, can accelerate the deployment of clean technologies, creating jobs and economic growth while reducing emissions. This collective effort fosters a bottom-up momentum that complements top-down policy.

Building energy abundance beyond political delays

The UK's vision should be a future with energy to play with - energy so abundant it stops being a constant concern. Despite global political challenges and potential delays in scientific reports, the UK can position itself as a leader by showing that having more clean energy is a powerful response to the climate crisis. This means not just meeting targets, but exceeding them, and creating a robust, secure energy system that is less vulnerable to international political fluctuations. By focusing on energy abundance, the UK can continue its journey towards net-zero, setting an example for the world.
