摘要：The climate change is defined as "a change of climate that is attributed directly or indirectly to human activ- ity that alters the composition of the global atmosphere and which is in addition to natural climate variability ob- served over comparable time periods" [1]. "Although a small quantity of greenhouse gases (GHGs) results from natural processes, most are emitted by human activities. Massive use of fossil fuels such as hydrocarbons (coal, gas, oil), deforestation, and intensive grazing and farm- ing produce large quantities of greenhouse gases, which concentrate in the atmosphere. GHG emissions accel- erate global warming" [2]. The climate change "has the potential to affect human health in a number of ways, for instance by altering the geographic range and sea- sonality of certain infectious diseases, disturbing food- producing ecosystems, and increasing the frequency of extreme weather events, such as hurricanes" [3]. "The science of the anticipation, recognition, evalu- ation and control of hazards arising in or from the workplace that could impair the health and well-being of workers, taking into account the possible impact on the surrounding communities and the general environ- ment" is a general definition referred to occupational health and safety [4].
