Global weather patterns are changing and with these changes come significant threats to the preservation of world archaeological heritage. An increasing number of coastal sites are vulnerable to inundation and ruin by rising sea levels. And as temperatures rise in some parts of the world those archaeological remains which have laid frozen in the permafrost, in a state of spectacular preservation, are beginning to thaw and rot. The need to raise awareness of how global climate change is affecting archaeological heritage is clear and the timeframe left to us to address this challenge is growing ever shorter. From Easter Island to the Altai Mountains, archaeological sites are increasingly at risk due to changing weather patterns and climate shifts.
