There is a wealth of data and information about weather, past climate, and future climate. It is available in magazines, reports, scientific journals and on the web. There is "data" in the form of archives of numbers. The data and information that is "right" for any individual project depends on a number of factors. What are you trying to do? What tools do you have for working with scientific data and information? We often find that our initial role is as a guide into the climate-science knowledge base. Please see GLISA's Climate Information Guide to get started at defining your information needs, access foundational climate resources, and work with GLISA to get the best available science and interpretation of that information.
