The international agreement focused on climate change that was adopted in 2015 is the Paris Agreement. This landmark accord aims to bring countries together in the fight against climate change by committing them to limit global warming to below 2 degrees Celsius above pre-industrial levels, with efforts to limit the increase to 1.5 degrees. The Paris Agreement encourages nations to set their own emission reduction targets and to transparently report progress. It represents a significant step in global climate action, emphasizing the need for collaboration among nations in addressing this critical issue affecting the planet.
