Website known issues:

  • While every attempt has been made to precisely render the graphical visualizations of the Time of Emergence results, in some cases there may appear to be slight offsets between the numerical data (in the exported data files) and the emergence dates graphed on the “all results” dotplots. The numerical data are correct. However, the precision of assigning a year to the Time of Emergence of a variable is low, and differences of a year or two are not meaningful.

Website updates:

  • May 2015: Corrected reversal of dates of emergence for variables with a negative (decreasing) trend resulting from fast vs. slow estimated rates of climate change. (If a variable emerges because of a decreasing trend, the Time of Emergence for a fast estimated rate of climate change was labeled slow on the website, and vice-versa.)


The Time of Emergence project was conceived and funded by U.S. Army Corps of Engineers Climate Preparedness & Resilience programs & U.S. Environmental Protection Agency-Region 10. Methodologies and stakeholder engagement were developed and implemented by the University of Washington's Climate Impacts Group. The Time of Emergence online tool was developed with support from the Center for Data Science, University of Washington-Tacoma.
