+# Chapter 3: AI for sea ice forecasting
+
+The changing climate patterns caused by Arctic amplification have led to an increase in the frequency and intensity of extreme weather events. The loss of sea ice in the Arctic, as observed through satellite data, is a crucial aspect of this phenomenon. Accurately forecasting Arctic sea ice on subseasonal to seasonal scales presents significant scientific challenges. In addition to physics-based Earth system models, researchers have explored the use of statistical and machine learning models for sea ice forecasting.
+
+In this chapter, we examine three different approaches for predicting monthly Pan-Arctic sea ice extent up to 3 months in advance: traditional machine learning, deep learning, and ensemble learning. Leveraging monthly satellite-retrieved sea ice data from NSIDC and atmospheric/oceanic variables from the ERA5 reanalysis product spanning the period of 1979-2021, we demonstrate the potential of ensemble methods in achieving promising predictive performance with longer lead times. These advancements will greatly enhance our ability to forecast future changes in Arctic sea ice, enabling us to make more informed predictions regarding transportation routes, resource development, coastal erosion, and the potential impact on Arctic coastal communities and wildlife.
