Most scientific articles related to climate change begin with data on the historical evolution of greenhouse gas emissions, the evolution of global warming and its effects, with catastrophic projections in the short and medium term if drastic measures to reduce emissions are not adopted. They present serious scientific data, based on the reports of the Intergovernmental Panel on Climate Change, based on which they make their projections, the most worrying being "the point of irreversible climate change" or "the threshold of climate danger", at which time humans will be able to do nothing to prevent the progressive deterioration of life on earth derived from its constant warming ; as well as the tensions between the interests of humanity and the chrematistics, "... Let's be more precise. A climate genocide is taking place, but it is not climate change that is destroying humanity, but those responsible for it, because they are also responsible for the effects of it" "The United Nations Framework Convention on Climate Change (Rio 1992) seemed to be the beginning of humanity's awareness of such a serious phenomenon, but since that date the large corporations have refused to provide substantive collaboration and the industrialized countries, in which their headquarters are based, have refused to conclude satisfactory binding agreements. Developing countries have not received the technological cooperation they require to be able to continue producing without serious emissions. A certain global advance took place at COP 21 Paris and COP 28 Dubay, but without consolidating the required international solidarity. So many announcements and international declarations full of drama and lack of concrete commitments recall the popular Tale Peter and the Wolf. This essay briefly analyzes international commitments, merits and shortcomings, with special reference to international scientific and technological cooperation, the difficulties caused to developing countries by a system of patents and technological secrets that, by making the use of cutting-edge technology more expensive, prevents them from protecting their territories and populations from the effects of climate change, and, in addition, to contribute to the world to the reduction or elimination of polluting emissions. It concludes by proposing that Mexico develop more solid policies in international negotiations on scientific and technological cooperation, on the eve of the foreseen in the T-MEC for 2026.
