Abstract <p>The state, significance, and place of legal acts on climate change prevention in the general and national systems of law and legislation are analyzed, and a number of literature sources on these topics are provided. The closest components of environmental protection to climate are atmospheric air; the ozone layer of the atmosphere; near-space; and vegetation, wildlife, and other natural resources. The opinion is substantiated that a set of climate regulations forms a legal institution or a subbranch of environmental law, which deserve further legal and other sociohumanistic attention and development.</p>
