'Scientifically COP30 has been nothing less than a failure,' researcher says • FRANCE 24 English

Key Concepts

• COP 30: The 30th Conference of the Parties to the UNFCCC, a major international climate change summit.
• Paris Agreement: An international treaty adopted in 2015 to combat climate change, aiming to limit global warming to well below 2, preferably to 1.5 degrees Celsius, compared to pre-industrial levels.
• Fossil Fuels: Carbon-based fuels such as coal, oil, and natural gas, formed from the remains of ancient organisms. Their combustion is a primary source of greenhouse gas emissions.
• Greenhouse Gas Emissions: Gases in the Earth's atmosphere that trap heat, contributing to global warming.
• Carbon Budget: The total amount of carbon dioxide (CO2) that can be emitted into the atmosphere while keeping the probability of exceeding a specific temperature limit (e.g., 1.5°C) at a certain level.
• Tipping Points: Critical thresholds in the Earth's climate system that, if crossed, can lead to large, often irreversible changes.
• Carbon Sinks: Natural systems that absorb and store carbon dioxide from the atmosphere, such as forests and oceans.

COP 30: A Subdued Outcome and Scientific Failure

The COP 30 talks concluded with a sense of disappointment, best described as "subdued." While an agreement was reached to increase funding for countries to adapt to extreme weather events, the final communiqué lacked explicit commitments to phase out fossil fuels or strengthen nations' inadequate emissions reduction plans, despite demands from numerous countries.

Expert Analysis: A Scientific Failure

Professor Yan Rostrom, Director of the Potsdam Institute for Climate Impact Research and Professor of Earth System Science at the University of Potsdam, unequivocally stated that from a scientific perspective, COP 30 was a failure. He highlighted that ten years after the Paris Agreement, global emissions are still increasing, temperature rise is accelerating, and hundreds of millions are already suffering from climate impacts. Rostrom emphasized the urgent need to "bend the curve of emissions" rapidly, requiring a 5% annual global reduction starting no later than 2025. He noted that COP 30, announced as the "COP of truth" and "COP of implementation," failed to deliver on its promise of focusing on work plans and roadmaps for accelerating the transition away from fossil fuels.

The Centrality of Fossil Fuels

Rostrom underscored that fossil fuel burning is responsible for approximately 75% of greenhouse gas emissions driving global warming. He expressed frustration that international negotiations, designed to prevent dangerous climate change, still struggle to address this primary source of the crisis. Despite efforts by the Brazilian COP presidency to initiate a roadmap for accelerating the phase-out of fossil fuels with monitoring, finance, and accountability mechanisms, this crucial objective was not achieved at the COP.

The Disappearing Carbon Budget and the 1.5°C Limit

The urgency of the situation is amplified by the rapidly diminishing global carbon budget for limiting warming to 1.5 degrees Celsius, as stipulated in the legally binding Paris Agreement. Rostrom warned that the world is at risk of losing the possibility of keeping the 1.5°C limit within reach. He criticized the tendency to express a wish to limit warming to 1.5°C while failing to address the root cause of the problem.

Disappointment in Forest Protection and Adaptation Funding

Beyond fossil fuels, COP 30 also fell short on other critical fronts. Rostrom identified the lack of progress on forest protection as a significant disappointment. He pointed out the irony of holding the COP at the edge of the Amazon rainforest, a vital carbon sink, yet failing to adequately address its protection. Scientifically, securing carbon sinks in major forest systems is as crucial as phasing out fossil fuels to prevent dangerous warming. Forests absorb about 25% of CO2 emissions from fossil fuel burning. Therefore, a roadmap for forest protection, alongside a roadmap for fossil fuel phase-out, was a key task for COP 30, and neither was realized in the final document. While more funding for developing countries to adapt to climate impacts was agreed upon, many argued it was insufficient.

Where Things Went Wrong: Unwillingness to Move Beyond the Status Quo

Rostrom attributed the COP's shortcomings to an "unwillingness to really start moving away from fossil fuels." He noted that while the Brazilian presidency made commendable diplomatic efforts, the final outcome reflected a resistance from key players, including Arab states, China, and large emerging economies like India. These nations, he suggested, are either unable or unwilling to acknowledge the severity of the crisis and opt for the perceived simplicity of continuing energy provision as "business as usual." This approach, he argued, is a failure to recognize the crisis for what it is, while hoping to avoid consequences by remaining static.

Real-World Implications for Ordinary Lives

The failure of COP 30 to initiate a turnaround has profound implications for ordinary people worldwide. Rostrom predicts that the 1.5°C limit will inevitably be breached within the next 5 to 10 years, leading to warming of 1.6-1.7°C and potentially towards 2.5°C by the end of the century. The consequences of this inaction will manifest as:

• Increased extreme weather events: More droughts, floods, fires, and life-threatening heatwaves affecting millions.
• More human-reinforced storms.
• Significant economic costs: Billions of US dollars lost globally due to climate impacts.
• Approaching tipping points: The risk of crossing critical thresholds in systems like the Amazon rainforest, tropical coral reefs, and the Greenland ice sheet. Crossing these tipping points could lead to irreversible melting of the Greenland ice sheet, equivalent to a 7-meter sea-level rise.

Rostrom concluded that continuing on the current dangerous path poses immense risks to humanity.
