This article discusses some of the major effects of global climate changes on biodiversity. First, living beings are characterized as genomorphophysiologic (dgmf) figures that react to climatic variations in a dynamic way, integrating their various levels of organization (genetic, metabolic, and morph physiologic) to form specific emerging patterns. Then, using the dgmf concept the ways that biodiversity react to the global climate changes are discussed. The network theory is introduced using a simple example, the GOL 1907 flight airplane crash, and the resulting chaos in air transportation. Considering the fundamental concepts regarding hierarchical and random networks, these are employed to raise the hypothesis that biodiversity probably responds to an “aggression” on hierarchical networks in the same way the air transportation system or the Internet does. With the biodiversity network concept in mind, proposals to prevent network raids are made by studying low redundancy network nodes (which are the most vulnerable nodes) and/or network nodes that, in spite of not being as important, could be connected to central nodes of biodiversity networks, that could cause cracker type network raids, such as in the air transportation chaos case in Brazil. Finally, the idea of hierarchical networks is broadened in a discussion about the connection with society, based on William Ruddiman's proposal of the existence of an

The hypothesis has been raised that the raids on biodiversity networks are more of the hacker type than cracker . However, if there is a cracker raid related to climatic change factors, such as variations over a certain level in the atmospheric concentrations of CO2, in temperature, and/or availability of water for photosynthetic organisms, the system of biosphere networks could suffer drastic changes in its balance producing something unique, and resulting in a new state. Some say that we already have enough knowledge and technology to find ways to avoid global instability, but not without great intellectual effort that would probably include using the network theory as a strategic tool.
