Climate Change Clearly Visible As Noaa Prepares To Release New Normals The fingerprints of climate change are seen in noaa’s new 30 year climate normals for the us, with many locations warmer and wetter than before. Climate normals are a 30 year average of recent climate conditions, according to noaa. they provide the baseline for comparing weather and climate to the recent past.
Climate Change Clearly Visible As Noaa Prepares To Release New Normals Climatologists from noaa national centers for environmental information (ncei) are currently compiling and reviewing 30 years of weather and climate data from across the u.s. to serve as the nation’s updated climate “normals” for the next 10 years. this new 30 year dataset will span from 1991 to 2020 and is scheduled for release in may 2021. A noaa expert discusses the new climate normals. on may 4, 2021, noaa released its updated 1991–2020 climate normals for the united states. climate normals are traditionally defined as 30 year averages of annual seasonal, monthly, daily, and hourly statistics of temperature, precipitation, and other climatological variables from almost 15,000. The data set reflects a “new normal” that takes the most recent 30 years of climate change influenced weather and climate conditions into account. (more: see our climate normals explainer.) a warmer normal. the u.s. climate normals collection has 10 versions: 1901 1930, 1911 1940 and so on through 1991 2020. in the image below, we’ve. In early may, the 30 year period covered by the official u.s. climate normals will shift from 1981 2010 to 1991 2020. because they are updated once per decade, the normals gradually come to reflect the "new normal" of climate change caused by global warming. over time, the "normal" annual u.s. temperature has grown warmer, and the "normal.
