Ten years after the historic adoption of the Paris Agreement, the world faces an unsettling reality: global temperatures are climbing faster than expected, and greenhouse gas emissions show little sign of slowing. According to the European climate service Copernicus, the planet’s average temperature has increased by approximately 0.83°F (0.46°C) since 2015, marking one of the most rapid 10-year jumps on record. Every year since the Paris summit has been hotter than 2015, and 2025 is on track to be among the top three hottest years globally (Copernicus, 2025).
The UN Environment Programme’s latest Emissions Gap Report highlights the growing disconnect between promises and outcomes. Current pledges put the world on track to temporarily exceed the 1.5°C warming threshold, likely within the next decade, threatening the very target that the Paris Agreement sought to enshrine (UNEP, 2025). UN Secretary-General António Guterres emphasized at a pre-COP30 event in Belém, Brazil, that “it’s no longer time for negotiations. It’s time for implementation, implementation and implementation.”
Rising Emissions and Their Impacts
Global emissions surged 2.3 percent in 2024, reaching a record 57.7 gigatons of CO₂ equivalent. India accounted for the largest absolute increase, adding 165 million tonnes, followed closely by China. While several developed nations—including the United States—have managed to reduce emissions by roughly 7 percent since 2015, China’s emissions rose 15.5 percent and India’s by 26.7 percent in the same period (Global Carbon Project, 2025).
The consequences of this accelerated warming are already evident worldwide. The U.S. endured 14 billion-dollar disasters in the first half of 2025 alone, totaling over $100 billion in damages, with the Los Angeles wildfires in January causing record losses exceeding $60 billion (NOAA, 2025). Meanwhile, glaciers and ice sheets have lost more than 7 trillion tons of ice since 2015, and global sea levels are rising at an accelerating pace—from 2.1 mm per year in the 1990s to 4.1 mm annually between 2016 and 2025 (NASA, 2025).
Renewable Energy and Technological Hope
Despite these sobering statistics, some progress offers hope. Global renewable energy capacity is projected to nearly double in the next five years, adding 4,600 gigawatts. In the first half of 2025, renewable energy overtook coal as the leading source of global electricity for the first time, with solar and wind growth more than meeting the 2.6 percent increase in electricity demand (IRENA, 2025).
Electric vehicle adoption is also surging. Global EV sales rose from 500,000 units in 2015 to 17 million in 2024, reflecting a growing commitment to decarbonizing transportation. However, policy reversals, such as the U.S. withdrawal from the Paris Agreement under the Trump administration and subsequent rollback of climate policies, have raised questions about consistent global participation in the clean energy transition (IEA, 2025).
COP30: A Critical Moment for Action
As diplomats gather in Belém for COP30, nations face intense pressure to revise their Nationally Determined Contributions (NDCs) with more ambitious targets. Current pledges would reduce emissions by just 15 percent from 2019 levels by 2035—far short of the 55 percent reduction needed to align with the 1.5°C pathway (UNEP, 2025). Experts warn that without immediate, enforceable measures, the Paris Agreement risks becoming a symbolic commitment rather than a transformative global pact.
The past decade shows that while technology and renewables provide tools for progress, global leadership and political will remain the critical determinants of success. From record-setting wildfires and floods to accelerating ice loss and sea-level rise, the signs are undeniable: the climate crisis is here, and delay is no longer an option. COP30 offers a chance to translate ambition into action—but the window to keep warming within safe limits is rapidly closing.
