It's only 4D in that the temp value is represented in foot height and you can use the slider to animate the sequence of fires.
Data taken from http://activefiremaps.fs.fed.us/gisdata.php
Terra and Aqua MODIS fire and thermal anomalies data generated from MODIS near real-time data acquired by the USDA Forest Service Remote Sensing Applications Center, University of Wisconsin Space Science and Engineering Center, University of Alaska-Fairbanks Geographic Information Network of Alaska, the NASA Goddard Space Flight Center Direct Readout Laboratory, and NASA Goddard Space Flight Center MODIS Rapid Response System. Data provided in shapefile and coverage formats and is updated hourly.
I recommend either clamping the silder to the beginning and pressing play or restricting it to a length of 1 month and sliding manually.
The file contains all fire data for California for 2006. Let me know how I can make it better.
