On September 2, 2025, at 11:45 AM, a global conference on climate change is set to take place, bringing together world leaders, scientists, and activists to discuss urgent actions needed to combat climate change and its effects. This event aims to create actionable plans and commitments to reduce carbon emissions and promote sustainable practices worldwide. Reflecting on the timeline, one month prior, on August 2, 2025, a significant report was released by the Intergovernmental Panel on Climate Change (IPCC) that outlined the dire consequences of inaction and the need for immediate policy changes. Looking back a year, on September 2, 2024, a major climate summit was held, where various nations pledged to enhance their efforts in reducing greenhouse gas emissions. Five years ago, on September 2, 2020, the world was grappling with the COVID-19 pandemic, which had temporarily reduced pollution levels and sparked discussions about the relationship between public health and environmental sustainability. Ten years ago, on September 2, 2015, the Paris Agreement was adopted by nearly every nation, marking a historic commitment to limit global warming to well below 2 degrees Celsius. Fifty years ago, on September 2, 1975, environmental movements were gaining momentum, with protests advocating for cleaner air and water, leading to the establishment of more stringent environmental regulations. A hundred years ago, on September 2, 1925, the modern environmental movement was still in its infancy, but awareness of pollution and conservation began to emerge, setting the stage for future advocacy. As we look back a thousand years, on September 2, 1025, the world was vastly different, with societies largely focused on agriculture and local ecosystems, but the seeds of environmental awareness were beginning to take root in various cultures around the globe. This timeline illustrates the evolution of environmental awareness and action leading up to the pivotal conference in 2025.
