There is an interconnection between the environmental global governance systems and cybersecurity. Understanding the interconnections between these and the role of law, policies and practices in the European High North (EHN) is critical to understanding the variables affecting both climate change and cyberspace. Although climate change and cyberspace are different phenomena, the risks associated with both of them are anthropogenic and can affect the same critical equities, including key sectors such as water, food and energy infrastructures. This study aims to better grasp the development of cyberspace and its revolutionary impact on human behaviour and human security. Throughout the article, there is an exploration of these two realms and discussion on how it came to be this way and its effects.
