The journal Climate Change recently published a joint article entitled “Strongly increasing heat extremes in the Middle East and North Africa (MENA) in the 21st century”. The collective of authors consists of the specialists Jos Lelieveld, Y. Proestos, P. Hadjinicolaou, M. Tanarhte, E. Tyrlis and G. Zittis. And their conclusions are dire indeed, as summarized by the journalist Matt Atherton: “Up to 500 million people living in the Middle East and North Africa [MENA] could be forced to leave their homes because of extreme heat predicted in the near future, researchers have said. A study has found that these regions will become uninhabitable by the end of the century, when temperatures of up to 50C will become the norm during the summer months”. Or, if you like a more scientific wording: “We conclude that the MENA is a climate change hotspot that could turn into a scorching area in summer. There is general consent that heat extremes impact human health, contribute to the spreading of food- and water borne diseases, and that more intense heat waves increase premature mortality. In the past, climate assessments of social and economic impacts due to changing weather extremes, including consequences for human security and migration, have often focused on storms, floods, droughts and sea level rise. It is increasingly recognized that hot weather extremes cause a loss of work capacity and aggravate societal stresses, especially for disadvantaged people and vulnerable populations (IPCC 2014). We anticipate that climate change and increasing hot weather extremes in the MENA, a region subject to economic recession, political turbulence and upheaval, may exacerbate humanitarian hardship and contribute to migration”.
Jos Lelieveld, Director at the Max Planck Institute for Chemistry and co-author of the above-quoted study, said that “[i]n future, the climate in large parts of the Middle East and North Africa could change in such a manner that the very existence of its inhabitants is in jeopardy . . . Climate change will significantly worsen the living conditions in the Middle East and in North Africa. Prolonged heat waves and desert dust storms can render some regions uninhabitable, which will surely contribute to the pressure to migrate”. Or, if you will, the present migration crisis in Europe is but the beginning of the real crisis that will surely happen as the century moves along into the near future . . . And at this juncture, the World Bank has also just released another report: “Water scarcity, exacerbated by climate change, could cost some regions up to 6% of their GDP by 2050, spur migration, and spark conflict, according to a new World Bank report High and Dry: Climate Change, Water and the Economy. The combined effects of growing populations, rising incomes, and expanding cities will see demand for water rising exponentially, while supply becomes more erratic and uncertain, the report finds, with these effects expected to be most pronounced in Africa, the Middle East, and Asia”.
