As nations prepare for the annual climate change conference in Baku, Azerbaijan, the urgency of addressing climate change is more pronounced than ever. Despite over two decades of international efforts to curb emissions, global greenhouse gas levels reached record highs in 2023. The upcoming conference aims to solidify a financial agreement to support more ambitious climate actions, a critical step given that financial constraints have historically stymied progress.
Current Emission Trends
Global emissions of carbon dioxide equivalent reached approximately 57.1 billion tonnes in 2023, marking a 1.3% increase from the previous year. This rise is concerning as it follows a pattern where emissions have only decreased once since 2000, during the COVID-19 pandemic. The Paris Agreement targets stipulate that emissions must peak by 2025 and be reduced by at least 43% from 2019 levels by 2030. However, current trajectories suggest these goals are unlikely to be met.
The Role of Greenhouse Gases
Greenhouse gases, particularly carbon dioxide, methane, and nitrous oxide, are responsible for global warming. Carbon dioxide levels have surged to 420 parts per million, exceeding pre-industrial levels by over 150%. The persistence of these gases in the atmosphere complicates the situation; for example, carbon dioxide can linger for centuries, meaning that even if emissions are curtailed, the warming effect may continue for years.
Impacts of Rising Temperatures
The implications of rising greenhouse gas concentrations are severe. The World Meteorological Organisation has reported that last year was 1.45°C warmer than pre-industrial levels, with projections indicating that average temperatures may surpass the critical 1.5°C threshold within the next few years. This potential breach could lead to catastrophic climate consequences, including more extreme weather events and biodiversity loss.
Future Projections and Challenges
The Intergovernmental Panel on Climate Change (IPCC) has called for a substantial reduction in emissions to achieve net-zero by 2050. However, recent assessments indicate that global emissions in 2030 may only be 2.6% lower than 2019 levels, far from the necessary 43% reduction. This minimal progress puts stress on a troubling trend of procrastination in climate action, where countries commit to incremental changes rather than the radical transformations needed.
Financial Implications for Climate Action
Financial resources remain an important barrier to effective climate action. The Baku conference is expected to address these financial needs comprehensively. Without adequate funding, nations may struggle to implement the ambitious measures required to combat climate change effectively. Historical negotiations have shown that financial commitments are often contentious, leading to stalemates in international agreements.
