Palynological analyses in north-western France reveal a significant 300-year arboreal increase (1700-1400 years BP), termed the '1.7-1.4 ka AP event'. This event coincides with the withdrawal of coastal societies, possibly due to subpolar North Atlantic gyre strengthening and increased storminess. The study suggests that climate degradation may have amplified the collapse of coastal agrarian societies at the end of the Roman Period.
