Around the world, climate change can be observed more and more. Record temperatures were recorded from year to year in major cities. Heat waves and important recurring aunts floods have occurred in recent decades. These disorders weather hitting the planet causing dramatic affect humans and agriculture, so the economies touched. Given this situation, the concern is to predict what climate changes can we expect to be able to build a socio-economic adapted to this climate. Morocco is not immune, either, extreme weather events. Covering an area approximately 710,850 km2, it has nearly 3,500 km of coastline along its Atlantic and Mediterranean coasts. The four mountain ranges in the High Atlas, Anti Atlas, Middle Atlas and Rif give it a diverse geography and a subdivision into at least four climatic zones: the Mediterranean coastal area, the Atlas Mountains and steppe or Saharian climate zone south of the line of the watershed. The regions of the Atlantic and Mediterranean coasts receive most of their rainfall between November and March. Because of the terrain, they vary between 300 mm on the Mediterranean coast a little drier and more than 700 mm in the north-west of Morocco. In winter there is often above 2500 mm, a snow cover that persists more than six months a lot. The foothills of the Sahara receive less than 200 mm per year, mostly in autumn and spring. This study aims to examine trends in extreme temperatures and rainfall recorded in various weather stations over the past five decades and future projections of these trends over the next five decades. It also aims to assess the potential impact of these trends on water resources and threats to agricultural production and biodiversity.
