The Guardian's Down to Earth editorial team is evaluating the effectiveness of the global fight against climate change in its 250th edition [1].

This assessment comes at a critical juncture as the world navigates a transformed political and economic landscape. By reviewing the gap between international agreements and actual environmental outcomes, the analysis highlights whether global efforts are keeping pace with the accelerating climate crisis.

The newsletter first launched in 2021 [2]. Over the five years since its inception [3], the editorial team has tracked the shift in environmental policy and the implementation of green technologies. This period of reflection aims to determine how much progress has been made toward the goals established during a pivotal era of climate diplomacy.

Central to this review is the legacy of the COP26 summit held in Glasgow, Scotland [4]. The summit lasted two weeks and served as a primary catalyst for current climate targets [5]. One of the most significant outcomes of that meeting was the agreement to pursue a target limit for global heating of 1.5°C [6].

The editorial team is now questioning if the strategies deployed since 2021 have been sufficient to meet that threshold. The review considers how political instability and economic shifts have influenced the ability of nations to adhere to the Glasgow commitments. While some technological advancements have occurred, the team is examining whether these gains are offset by continued emissions.

The 250th edition serves as a benchmark for the newsletter's own journey and the broader global movement. By comparing current data to the baseline established five years ago, the team seeks to identify which policies failed and which provided a viable path forward.

This retrospective highlights the tension between long-term climate targets and short-term political and economic volatility. By using the COP26 summit as a benchmark, the analysis underscores the difficulty of maintaining a unified global trajectory toward the 1.5°C limit amid shifting national priorities.
