Climate science research focuses on strategically important scientific problems whose solution will enable advances in the measurement, modelling, and forecasting of climate risks and will thereby enhance our ability to weigh these risks against the costs of climate change mitigation and adaptation. These scientific advances are being facilitated by the development of novel, low-cost sensor devices and platforms for observing the atmosphere, oceans, glaciers, and ecological systems, and by applying recent advances in computation and data science to the data acquired from these new observational platforms.
