Earthzine is an online resource for news, articles, reviews, information, and educational materials about Earth Science, Earth observations, and utilization of Earth information. It is a contribution of the IEEE Committee on Earth Observation (ICEO) in support of the Global Earth Observing System of Systems (GEOSS). The ICEO created Earthzine as a venue to promote community among Earth's observers and create greater awareness of Earth observations among the general public. It is updated regularly with news from around the world about Earth observations, environmental policy, and new and emerging environmentally friendly and earth-observing technologies. It includes articles on themes relevant to the nine societal benefit areas identified by GEOSS: disaster reduction, human health improvement, energy resource management, water resource management, understanding and adapting to climate variability and change, improved weather forecasting, management and protection of ecosystems, sustainable agriculture, and understanding and conserving biodiversity.
