Event Summary: The National Atmospheric and Oceanic Administration (NOAA) is advancing the scientific understanding and prediction of climate through state-of-the-art numerical modeling of the Earth system. This event will highlight climate change including extremes in the 21st century, their evolution, and how advances in modeling can improve the information for impacts assessments. The research and products span the wide time scales of interest, with the spatial scales ranging from global to regional. This event will focus on Africa with extensions to the rest of the world. Issues that will be discussed include: regional temperature and precipitation changes; intercontinental transport of pollutants affecting air quality and climate, and the global presence of dust; hurricanes and other storms affecting lives and property; and seasonal-to-decadal predictions of droughts and heat waves. The research comprises understanding the causes of changes in past climate from natural and human-influenced factors, projecting future change corresponding to technological and economic scenarios, and modeling the resulting changes in climate. The objective is to deliver credible, trustworthy, and actionable information to decision-makers in a wide variety of sectors (e.g., agriculture, forestry, health, coastal, river and ecosystem management, infrastructural protection), and enable the assessment of climate impacts to address the societal challenges of vulnerability, adaptation, and mitigation.
