AMAP Climate Change Update 2019

An Update to Key Findings of Snow, Water, Ice and Permafrost in the Arctic (SWIPA) 2017. Drawing and building on the findings of AMAP: Snow, Water, Ice and Permafrost in the Arctic (SWIPA) 2017 assessment, this document provides updated observations, information from other recent assessments, and conclusions from the latest reviews of Arctic trends and indicators. The pace of change in the Arctic is so rapid that new records are being set annually, and each additional year of data strengthens the already compelling evidence of a rapidly changing Arctic.
