History

Historical Context

Since the Industrial Revolution around 1750, human activities have significantly increased atmospheric carbon dioxide levels, surpassing 400 parts per million (ppm) in 2015. By 2024, levels reached 423.9 ppm, driven by fossil fuel combustion and exacerbated by wildfires in South America and Canada. This trend emphasizes the urgent need for effective climate policies to mitigate ongoing environmental impacts and protect ecosystems.
