Using the Area Selection Type Menu to the left, edit types of selection areas:
Select various chart options in the dropdown menus to the right, which can include Month, Model, and Temperature ranges (High, Low, or Average).
Note: The first set of chart options control the variables being viewed on the map.
Click "Add Chart" to create an additional chart to compare with. After creating the new chart, click on a new area of the map to view a chart for the same options in another location. Or change an option in the dropdown menu to view the chart for the same location, with different settings.
To edit the first chart again, either directly edit the dropdown menus, or click on the Location Name and then click on a new location on the map.
Click "Predefined boundaries" in the Area Selection Type Menu to the left before clicking on an area of the map, if you'd like to compare counties to one another.
Fix the locations of the graphs to one area by clicking this toggle.
Global models indicate that California may see up to a 55 inch (140 cm) rise in sea level within this century given expected rise in temperatures around the world. The following map tool displays areas that may be in threat of inundation during an extreme flood event (100 year flood).
These data were developed by scientists from the USGS (Bay Area) and Pacific Institute (Coast). Blue color indicates areas already in threat today, while the lighter shades are area projected to also be in threat given the expected sea level rise.
These maps do not currently take into account protective structures, such as levees. New maps are currently being developed by reseachers to include these structures.
More up to date information on the the State's response to sea level rise may be found at the Coastal and Ocean Climate Action Team.
Create a chart by clicking a location on the map and altering one of the dropdown option boxes.
