Climate Challenge: A Decade After Paris Agreement

WHO: Scientists, policymakers, and the global community WHAT: A comprehensive review of climate progress and challenges one decade after the Paris Agreement WHERE: Globally, with focus on key regions including the Americas, Europe, Asia, Africa, and the Pacific WHEN: 2025, marking ten years since the adoption of the Paris Agreement in 2015 WHY: To evaluate how far the world has moved toward limiting global warming to 1.5 °C, identify persistent gaps, and outline the urgent actions needed to accelerate adaptation and mitigation efforts In 2015, the Paris Agreement set a vision to keep the rise in global average temperature well below 2 °C, with the pinnacle goal of limiting it to 1.5 °C. Ten years on, the scientific consensus is clear: Earth’s temperature has moved from 1.1 °C above pre‑industrial levels in 2020 to 1.2 °C in 2023, driven by the largest sectoral sources of greenhouse gases. The Intergovernmental Panel on Climate Change (IPCC)’s 6th Assessment Report confirmed that emissions need to fall by 45–55 % from 2010 levels by 2030 and reach net zero by 2050 to stay within the target, yet the global emissions trajectory remains far from these goals. #### Carbon Emissions Are Still Rising Between 2019 and 2022, global CO₂ emissions from fossil fuels and industry increased by roughly 2 %, reaching about 9.8 GtCO₂ in 2022, up from 9.1 GtCO₂ in 2019. While renewable energy capacity has grown—solar PV installed more than 3 GW in 2022 alone—coal production remains the largest single energy source in many major economies, halting the pace of decarbonization. International data from the International Energy Agency (IEA) indicates that the share of coal in global primary energy consumption is still 28 % as of 2022. #### Paris Commitments: Withholding, Making, and Missed Targets All 190 UNFCCC Parties have submitted updated Nationally Determined Contributions (NDCs) following the 2021 “Paris Climate Talks.” Even with revisions, the collective NDCs target a 1.5 °C cap with only a 36 % overall emission cut relative to 1990 levels by 2030—farthest from the once‑required 43 % as outlined in the 2015 Paris targets. Current politics show unwavering pledges, but implementation lag. Although the European Green Deal has set 55 % reduction targets by 2030, a comparative analysis of data from Eurostat places Europe’s total greenhouse gas emissions at a projected 23 % decline by 2030, short of the required value. #### Adaptation Gaps and Climate Resilience Global adaptation budgets have been insufficient. The Global Adaptation Fund, launched by the Green Climate Fund in 2020, reported receipt of only 10 % of the promised 10 bn USD by 2024 from developed countries, delaying critical infrastructure upgrades in the Caribbean and sub-Saharan Africa. #### The Way Forward 1. **Accelerate technology deployment** – Focus on next‑generation renewables, hydrogen, and carbon capture. 2. **Strengthen policy enforcement** – Align national legislation with NDCs and ensure transparent monitoring. 3. **Prioritize equity** – Amplify support for least‑developed countries vulnerable to climate impacts. 4. **Bridge finance gaps** – Mobilise private capital for climate adaptation projects. In summary, the world’s response to the Paris Agreement has made significant strides, but the energy mix remains fossil‑fuel heavy and emissions are still on the rise. The next decade will demand an unprecedented scale of policy commitment and financial mobilization to prevent the highest‑risk temperature thresholds.
