{5a} The Most Beautiful Graph on Earth - A. Hessler

This is Repost from my mud wrestling blog.  It's my attempt to systematically explore and describe this Global Heat and Moisture Distribution Engine that sustains us all.

In my next post I will try to summarize a paper by Angela Hessler "Earth's Earliest Climate".  But I thought this graph of their's deserves it's own post.  It's pretty fascinating particularly when also considering Earth's biological history. 

Okay, I'm not positive it's the "most" beautiful graph on Earth, beauty is in the eye of the beholder - but I am sure it's a fantastic window into the physical reality of our Earth and how the pageant of time has created the biosphere we humans take oh so for granted.  Hope to be back soon.

Earth's Earliest Climate

thin red line, that drops dramatically and then has a couple spikes = Impact rate
doted red line = Solar luminosity
dark green line = CO2 
light green line = CH4 (methane)
red line = O2
blue line = Ocean surface temperature
Two vertical bands, in the Archean = earliest sedimentary rock formation (continent building)
Dark gray vertical bands = glacial episodes

(The moon would have formed shortly after accretion ended (the white bar), early in the Hadean)
(The reign of humanity would fit within tiniest vertical sliver at the far right end of this graph)
