I've been searching for a way to record my local strike data without having to write it down from the screen list; I think this works. I am a total novice with Google Earth (GE), so others may know of an easier way.
On GE, left panel, click through the arrows to open up "Lightning Data", "Detailed View", then "Strikes in View" (I think that is your current screen area).
Then, right click on "Strikes in View" and email the .KMZ file to yourself. After you receive the .KMZ file, rename the extension to .zip and unzip the file. You get a .KML file that contains all of your strikes in text. It's still embedded in lots of extraneous code, but at least the recently recorded strike data is all there in readable form. I suppose a small amount of code could put just the entries into a list or excel, or something like that. Maybe there are canned programs to work with extracting data from .KML files?
Anyway, the individual strike data there (date, time, polarity, lat, lon, current)! Now, I can think about my amateur science experiments using the data.
