The Paris Agreement on Climate Change is a landmark international treaty adopted in 2015 that aims to address global warming by limiting the rise in average global temperatures to below 2 degrees Celsius, ideally to 1.5 degrees Celsius, compared to pre-industrial levels. This agreement marks a collective effort by countries around the world to combat climate change through nationally determined contributions (NDCs) and long-term climate strategies, highlighting the ethical responsibility to protect the environment for future generations.
