The large-scale movements of people from Syria, Iraq and Afghanistan to Europe are not the result of climate change alone but are due to complex interactions between various factors:

Climate dates about Syria show that the region warmed by about one degree over the last century. The serious drought 2006-2010 was the worst since the beginning of measurements at the beginning of the 20th century. About 1 1/2 million peasants lost their livelihood, and many moved to different parts of the country.

Therefore, not climate change alone but the lack of adequate political measures must be held responsible.
