The warning from the UN regarding the imminent breach of the 1.5°C global warming limit is the culmination of decades of scientific research, international negotiations, and policy failures. The Paris Agreement, adopted in December 2015, aimed to limit global temperature rise to well below 2°C, with aspirations to restrict it to 1.5°C above pre-industrial levels. However, despite the urgency expressed by scientists and advocates, global greenhouse gas emissions have continued to rise. The Intergovernmental Panel on Climate Change (IPCC) has consistently underscored the need for immediate and substantial reductions in emissions, yet many nations have struggled to meet their commitments. Historical events, such as the 1997 Kyoto Protocol and the 2009 Copenhagen Summit, illustrate a pattern of ambitious goals often undermined by political inertia and economic considerations. The current trajectory, with projections suggesting a rise of 2.6°C by the century's end, starkly reflects a failure to translate rhetoric into effective action. The implications of exceeding the 1.5°C threshold are profound and multifaceted. A rise in global temperatures is expected to exacerbate extreme weather events, disrupt agricultural productivity, and threaten water security, particularly in vulnerable regions such as sub-Saharan Africa and South Asia. Economically, sectors reliant on climate-sensitive resources, such as agriculture and fisheries, may face severe challenges, reminiscent of the widespread droughts and crop failures seen in 2018, which affected millions globally. Additionally, energy prices may rise as the demand for cooling increases and as fossil fuel resources become scarcer due to regulatory pressures. The economic ramifications could lead to increased social unrest and migration, further complicating geopolitical stability. Key players in this ongoing climate crisis include national governments, international organisations, and non-governmental entities.
