Last year (2017) was one of the three hottest years on record, with many high-impact events including catastrophic hurricanes and floods, debilitating heat waves and drought. Long-term indicators of climate change continue unabated and arctic sea ice coverage remained below average. Of the hottest years on record, 15 out of 17 have come since 2000. By contrast, more than a century has gone by since the planet had a record cold year (1911). At European level, based on the three different observational records of gl...

As a natural hazard, drought is best characterized by multiple parameters of climate, hydrology, meteorology etc. Understanding the links (relations, interdependencies) between these parameters is critical for identifying, adopting and implementing measures for mitigating the impacts of droughts. The reasons for the occurrence of droughts are complex, because they are dependent not only on the atmosphere but also on the hydrologic processes which feed moisture to the atmosphere. Moreover, the conceptual and struct...

Before presenting in detail the theme that this paper deals with, it is necessary to integrate the research on this matter within the larger context of climate change, which is at this time in a stage of unprecedented evolution. Worldwide, in the actual context of climate changes, more frequent and powerful natural disasters are expected. Disasters, representing a direct consequence of climate change, have also a negative impact on the environment as they are an obstacle to achieve sustainable development. In part...
