From the analysis of the present situation, a significant global warming during the current century appears to be inevitable, with likely catastrophic increases of temperature (4°C by 2100). urgently, all countries should establish comprehensive adaptation programs. Furthermore, in order to alleviate the situation, it will be necessary to appeal to all the available mitigation options, including short lived compo
