The weather and climate of the Arctic have been changing rapidly in recent years, with profound transformations projected to continue. These changes provide opportunities, such as new, shorter shipping lanes between Europe and East Asia; at the same time, however they expose society to major risks, such as environmental hazards associated with increased human activities in the Arctic. Climate change also poses major challenges for indigenous communities who are facing changes in predictive weather capacity based on traditional knowledge (non-stationary climate). Furthermore, anthropogenic climate change is amplified in the Arctic with a possible impact on the weather and climate in mid-latitudes, including potential changes in frequency and intensity of extreme events in Europe.
APPLICATE aimed at developing enhanced predictive capacity for weather and climate in the Arctic and beyond, and to determine the influence of Arctic climate change on Northern Hemisphere mid-latitudes, for the benefit of policymakers, businesses and society all alike.
APPLICATE has responded to the needs of the majority of stakeholders for enhanced predictive capacity from weather to climate time scales. APPLICATE has brought together experts from academia, research institutions and operational forecasting centres. A wide range of stakeholders and users were included in the project through the User Group, and other project outreach activities and regularly consulted to effectively exchange knowledge on the latest science and user needs.
By its end in April 2021, APPLICATE has helped to improve stakeholders’ capacity to adapt to climate change through a comprehensive analysis of the latest generation of climate models, which has informed the latest IPCC assessment report AR6. APPLICATE has improved the trustworthiness of climate change projections through an improved representation of important Arctic processes in next generation climate models. Furthermore, APPLICATE has contributed to narrowing the uncertainty of climate change projections by exploiting the concept of emergent constraints, leading to a greater adaptation capacity.
