This article sorts out how global warming has gone from research in the field of climate science to attention to the field of medical and health. As a major risk to mankind, some traditional propaganda on climate change and climate governance have failed to gain the understanding and support of some people. The non‐urgency, negative externality, and tragedy of the commons contained in climate ethics and intergenerational justice make climate governance gradually enter the condition of Giddens Paradox. Meanwhile, as countries attach great importance to the medical health of the people and individuals, the potential threats to human medical health brought by climate change have gradually attracted new attention. For instance, the spirit of anti‐epidemics displayed after the outbreak of the COVID‐19 shows how people value their lives and health and their strong ability to fight against it. The threat towards medical health brought by climate change and its urgency is not only important reasons for building a community of human and nature, but also a source that motivates the people to actively participate in climate governance. It helps improve the philosophical framework of climate governance and plays an important role in building a community of human and natural life.
