Climate, conflict and forced migration
Open accessAbstract
Despite the lack of robust empirical evidence, a growing number of media reports attempt to link climate change to the ongoing violent conflicts in Syria and other parts of the world, as well as to the migration crisis in Europe. Exploiting bilateral data on asylum seeking applications for 157 countries over the period 2006–2015, we assess the determinants of refugee flows using a gravity model which accounts for endogenous selection in order to examine the causal link between climate, conflict and forced migration. Our results indicate that climatic conditions, by affecting drought severity and the likelihood of armed conflict, played a significant role as an explanatory factor for asylum seeking in the period 2011–2015. The effect of climate on conflict occurrence is particularly relevant for countries in Western Asia in the period 2010–2012 during when many countries were undergoing political transformation. This finding suggests that the impact of climate on conflict and asylum seeking flows is limited to specific time period and contexts.

Although there is some disagreement, the preponderance of the literature suggests that climate change has contributed to civil strife in Syria.
“Although there is some disagreement, the preponderance of the literature suggests that climate change has contributed to civil strife in Syria [76–78].”
From Climate Change, Migration, and Civil Strife. (2020) · cites this paper as [78]
The literature review describes a pathway by which climate change and drought may have contributed to political unrest in Syria, while acknowledging a study that disputes the evidence. It also says there is little statistical evidence for the Syria-specific link; it does not establish that the preponderance of the literature supports it. The supplied copy gives a section label but no page number. (LLM, conf=0.84)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
