Step-by-step explanation:
According to scholar Harold James, the greatest emerging threats to the international system are economic instability, cybersecurity threats, and climate change. Each of these threats poses a significant risk to global security, economic well-being, and the environmental health of our planet. Economic instability includes elements such as global financial crises, which can undermine economies worldwide. Cybersecurity threats encompass a wide range of cyber-attacks that can disrupt governments, industries, and private lives. Finally, climate change is an existential threat that contributes to global refugee crises, as well as exerting pressure on global military actions, political instability due to poverty, and disturbances in various other human societal areas. All of these threats require robust strategies for mitigation and global governance to manage the anarchic nature of the international system, ensuring the safety, economic stability, and human rights protection of people around the world.
