While world leaders convene in the Brazilian Amazon for the 30th UN Climate Change Conference, it is vital to assess how we are faring together in cutting worldwide emissions of greenhouse gases.

In spite of 30 years of UN climate summits, approximately half of the carbon dioxide accumulated in the atmosphere after the dawn of industrialization has been emitted since 1990. Incidentally, 1990 was the publication of the First Assessment Report by the Intergovernmental Panel on Climate Change, which confirmed the threat of anthropogenic climate change. While researchers prepare the upcoming IPCC report, they do so aware that their work remains eclipsed by political agendas. Regardless of sincere attempts, the planet is remains dangerously off track to prevent catastrophic climate change.

Unprecedented CO₂ Levels and Fossil Fuel Dependency

Recent data indicate that atmospheric carbon dioxide levels reached a record high of 423.9 parts per million in 2024, with the increase rate from 2023 to 2024 jumping by the largest yearly increase since modern measurements began in the late 1950s. Based on the Global Carbon Project, 90% of total global CO₂ emissions in 2024 originated from the combustion of carbon-based energy sources, while the other tenth was due to land-use changes such as deforestation and forest fires.

While the increase in fossil CO₂ emissions in recent times was propelled by higher use of natural gas and petroleum—representing more than 50% of global emissions—the use of coal also attained a historic peak, constituting forty-one percent. In spite of the previous climate summit's evaluation calling for nations to move beyond fossil fuels, collective plans still aim to extract over twice the quantity of fossil fuels in 2030 than aligns with keeping planet heating to 1.5C, with continued extraction of natural gas justified as a lower emission bridge fuel.

The Mirage of Eco-Friendly Measures

Rather than focusing on economic incentives to speed up the elimination of carbon fuels, climate policies are overly dependent on feelgood eco-positive approaches that aim to neutralize carbon emissions by planting trees instead of reducing industrial emissions. Although protecting, enlarging, and restoring ecological absorbers like forests and wetlands is beneficial in itself, studies has shown that there is insufficient territory to reach the global goal of carbon neutrality using ecological methods by themselves.

Approximately 1 billion hectares—an area bigger than the United States of America—is needed to fulfill net zero pledges. Over forty percent of this land would need to be converted from current applications like agriculture to carbon sequestration projects by the year 2060 at an never-before-seen pace.

Even if this ideal restoration could be realized, woodlands take time to mature and are susceptible to fires, so they cannot be considered as a quick or lasting CO2 retention method, particularly in a rapidly shifting climate. As severe temperatures and aridity engulf more of the planet, these well-intentioned efforts could actually be destroyed by fire.

The Weakening of Natural Carbon Sinks

Research data indicates that about 50% of the carbon dioxide released annually stays in the air, while the remainder is absorbed by seas and terrestrial systems. As the planet warms, these environmental absorbers are losing efficiency at capturing CO₂, which means that additional CO2 accumulates in the air, intensifying global warming. Transferring the mitigation burden onto the agricultural and forest sectors simply relieves the oil and gas sector from the pressure to cut pollution any time soon.

The Climate Liability and Coming Populations

Achieving carbon neutrality by mid-century demands carbon dioxide removal (CDR), which at present relies almost exclusively on land-based measures to soak up excess carbon from the atmosphere. Emitting companies can easily buy carbon credits to compensate for their emissions and continue with business as usual. Meanwhile, the energy imbalance caused by the combustion of hydrocarbons continues to further disrupt the global climate system. In effect, we are increasing our climate liability to our planetary credit card, passing on our descendants with an insurmountable burden.

To curb the scale and length of overshoot the global warming targets, the world eventually needs to surpass the balancing impact of carbon neutrality and start to drawdown cumulative historical emissions to achieve a carbon-negative state.

The Policy Misrepresentation of Net Zero

Based on the latest numbers from the international carbon research group, vegetation-based CDR is currently capturing the equivalent of about 5% of yearly CO2 from fuels, while engineered carbon extraction accounts for only about one-millionth of the carbon released from carbon sources. More generous sector projections place it at around zero point one percent of worldwide CO2 output. Without meaning to be controversial, the policy twisting of net zero is an insidious loophole that takes focus away from the scientific imperative to eradicate the main source of our warming world—fossil fuels.

The Urgent Need for Definite Steps

While this scientific reality should dominate discussions at the climate summit, past events suggests that gradual, cautious steps and deference to politics will prevail. Vague statements of future ambition will continue to delay the pressing requirement for concrete immediate action. Until policymakers are brave enough to implement carbon pricing to bring the era of fossil fuels to a definitive end, we are adding more and more carbon to the atmosphere, compounding the environmental disaster now unfolding all around us.

The dilemma we face is simple: genuinely respond to the scientific reality of our crisis or endure the results of this profound moral failure for centuries to come.
