Climate change is likely to lead to increased competition for resources such as water and land, as well as increased migration and conflict. However, it is not likely to lead to increased trade, as climate change is likely to disrupt global supply chains and make it more difficult for countries to trade with each other.

Ignoring climate change and hoping that it will go away is not a viable option, as climate change is a serious threat to human health and well-being. International cooperation and diplomacy are essential to developing new technologies, sharing information, and establishing new agreements to address climate change.

The lack of a global consensus on the science of climate change, the different levels of development and capacity among countries, and the political and economic interests of individual countries are all key challenges to international cooperation and diplomacy on climate change. However, the lack of a global government to enforce climate change agreements is not a key challenge, as there are a number of existing international institutions and mechanisms that can be used to enforce climate change agreements.

International cooperation and diplomacy on climate change can lead to reduced greenhouse gas emissions, increased resilience to climate change impacts, and improved economic development. However, it is unlikely to lead to increased conflict and instability, as climate change is a common threat that countries can work together to address.

The Paris Agreement on climate change is based on the principles of common but differentiated responsibilities and respective capabilities, equity and justice, and sustainable development. The principle of non-interference in the internal affairs of states is not a key principle of the Paris Agreement.
