Climate change and aerobiology

Climate changes can be considered a major threat for global health to be faced during the next decades. Human activities and production processes are directly affecting the weather, particularly in terms of gas generation responsible for the greenhouse effect. The consequent increase of global warming, associated (and sometimes linked) to extreme weather extreme events, affects human health in different ways. Among these, we should underline the increase of allergic pathologies, and the worsening of previous diseases, since there is a strong correlation between climate changes and the pollen production, the atmosphere concentration and allergenic sensitivity, the pollens seasonality and, finally, the geographical distribution of plants and related pollens. The association of these factors with the exposure to pollution can initiate even worse disorders. The allergist is primarily involved within the process aimed at solving or at least minimizing the effects already observed and that are expected to be produced in the future by climate changes over medical diseases.
