I put your data into a text file, and, adapting from the example in
the help, did
a=(read_ascii('testkml.txt')).(0)
p=plot([0,0],/
nodata,xrange=[-180,180],yrange=[-90,90],map_projection='equ irectangular')
poly=polyline(a[0:1,*], /data, color='red', name='testkml.txt',
thick=2.)
p.save,'test.kml'
And got a file that seems to work in Google Earth. But I do not know
how to do it with variable colors (do not even know if Google Earth
supports it in a line).

You'll need to simply make a basic kml document with a bunch of
placemarks representing each point. For each placemark translate your
intensity into a color value of your choosing represented by the
<color> tag in kml. You'll need to have a intensity to color
transformation and just for loop your way through writing out each
Placemark tag...basic construct..
