Climate consists of the long-term averages of daily weather, usually in 30-year periods. Climate can affect not just how we go about our daily activities but also our overall health. While having the tremendous advantages of temporal and spatial completeness, these reconstructions: (1) are based on computer models that may have model-based errors, (2) are coarsely sampled on a 50 km grid and are therefore unable to reconstruct the local variations of many microclimates, and (3) have particular difficulty with the weather in some coastal areas, especially small islands.
