NOAA Climate Timeline Information Tool (CTIL)
Created by a division of NOAA's National Climatic Data Center, CTIL contextualizes climatological information by comparing meteorological and climate patterns, events, and processes from successive time periods: 1 day, 1 year, 10 years, 100 years, 1000 years, 10,000 years, and beyond. Each timescale offers its own collection of resources.
