Abstract
Climate change is one of the environmental problems that endanger life on Earth today; this phenomenon has caused negative consequences on the planet that affect the well-being and safety of living beings, which constitutes a great concern for humanity. For these reasons, the international community has drawn up various treaties and legal regulations, bearing in mind that to counteract this phenomenon requires all countries' cooperation and participation through effective international response, following their responsibilities regarding the damage caused to society. However, they have not managed to reverse most of the environmental problems humanity suffers as countries have not ratified international conventions, being among the most polluting worldwide. The general objective of this chapter is to establish, based on a theoretical and legislative study, the need to adhere to the international law on climate change with a view to mitigation and adaptation to its effects on an international scale.
