We don't even have a particularly good data model. If you're interested in the water cycle, you'll have to construct that data from dozens of agencies in hundreds of governments. If the data was collected, linked together and published in an accessible form, more people could experiment with statistics, machine learning and visualization. Right now the data is in labyrinthine web forms, SOAP services, XLS files, GIS systems, etc. The barrier to entry needs to be lower.
