In what ways and by how much? Many people, including climatologists, have been struggling with these questions for some time now, not only for scientific interest but also to aid in policy decisions (IPCC 2001) and to inform the general public. In order to answer these questions, it is important to obtain comprehensive and intuitive information which allows interested parties to understand the scientific basis for confidence, or lack thereof, in the present understanding of the climate system. One tool, first developed as a framework for quantifying observed changes in climate within the contiguous United States, is the U.S. Climate Extremes Index (CEI). The U.S. CEI is based on an aggregate set of conventional climate extreme indicators which, at the present time, include the following types of data: - monthly maximum and minimum temperature - daily precipitation - monthly Palmer Drought Severity Index (PDSI) - landfalling tropical storm and hurricane wind velocityClimate Extremes Indexclimate changenoaaclimate extremes index ceiClimate Extremes Index for the Northeast1910-01-01See NOAA for more information on how these indices were computed and how to interpret them: https://www.ncdc.noaa.gov/extremes/cei/definitionSummarizing and presenting a complex set of multivariate and multidimensional climate changes in the United States so that the results could be easily understood and used in policy decisions made by nonspecialists in the field.Z1240_2494_R5ZJNEVMC.1240.2494mySQLNOAA.
