We were slowly cooling at the end of an #interglacial by #Milankovitch cycles, cooling faster since then towards a max glacial, pdf,#Iceages didn't happen until:

¹ #Antarctica flew off to open the #SouthernOcean 
² India leafed its way into Asia like cards to raise the #Himalaya from the #Eocene on removed most of the #CO2 by #rock_erosion 
³ The #IsthmusOfPanama filled in from #volcanics cut off flow E.Pacific to Atlantic a biggie created the #GulfStream for Europe 

Early cycles equal 41ky #LatePliocene  [1ky=1000y], Sahara wet/dry cycles fit 2 into 1 of these, then way variable cycle to end 100yrs past 800ky avg 185ppm-215ppm min-to-max

Max CO2 305±5ppm prior to KingCoal we 🐝 at 427ppm times 1.7-aggi for all #greenhouse #gases is 727ppm CO2eqv #pliocene values #sealevel rise >40m/130ft higher #sportsfans what are the odds it won't ?

I'll ask @deepseek_ai ... lol ...
