Due to greater variability, the phenomenon appears later in temperate zones, during the period 1980-2000, this is thus illustrated in the graph by the increase in the global temperature index since 1980 preceded by a slight decline between 1960 and 1979.

CLIMATE CHANGE INDICATORS A definition of climate change has been explained by the IPCC which was created to study climate change and present the risks of it on the economy in general by offering potential solutions to organizations(IPCC, 2019)12. Organizations are established to study the evolution of climate change and present reports highlighting its consequences. Indicators are thus made available to analyze this phenomenon. According to the National Observatory on the Risks of Global Warming (ONERC), an indicator is information associated with a phenomenon which makes it possible to indicate its evolution.(Gouv.fr, 2020).13 In other words, it is about concrete data and facts allowing to note the existence of a phenomenon. These indicators form the identity of the 12IPCC, “The special report on the oceans and cryosphere in a changing climate”, IPCC, [online], 2019.
