New extreme heat tool


New extreme heat tool. One of the most serious threats to the public health of Californians, that has already presented a challenge to date, are extreme heat events. Climate models, developed by the Scripps Institution of Oceanography, project that extreme heat events will increase in frequency, intensity, and duration given future climate change.


Our publications database has been updated with dozens of new peer-reviewed publications related to climate change in California.  Explore the collection of references in Publications.


There are a variety of different models and scenarios for any given type of data (temperature, precipitation, etc.), and it is important to convey the fact that one line in a chart only represents one of many potential outcomes. Given the fact that it is impossible to predict exactly what the future will look like, particularly in terms of changing demographics, socioeconomic factors, and scientific innovations, many different projections are made in an attempt to cover the range of potential outcomes that may be expected.

In order to address uncertainty in the data, it is helpful to display the entire range of available outcomes in charts and figures that display projected data. This is usually represented through the use of a shaded area on a chart that displays the lower and upper bounds of all of the available modeled results. Previously, charts in Cal-Adapt that depict temperature over time displayed a single line depending on the model and scenario selected for display. Charts now are able to plot not only the currently selected line but also the range of potential values as derived from all of the available models. This feature is currently available in the decadal temperature averages map and the degrees of change map.
