Seems like the earth temp was barreling upward for thousands of years before humans established civilizations and pretty much stopped, moved downward during the last 8000 years. So in the last 40 or 50 it is bumping up again. I am much less convinced about anthropogenic climate change after seeing this chart, not more

You are wrong, sooooo wrong.
"seems like"?? How about facts?
The world is warming at least 10 times faster than when it came out of the last ice age.
It took 10,000 years to warm by 5 C. That averages 2,000 years for each 1 C warming.
Global average temperature has increased by 1 C in the last 140 years. Do the simple arithmetic. I got 16 times faster now.
And why is that? Because we are increasing CO2 at least 100 times faster than the fastest that nature has done in at least the last 450,000 years.
Humans increased CO2 by over 80ppm in 60 years
Humans increased CO2 by 130ppm in 140 years
------
Nature caused CO2 increases over the last 450,000 years, from ice core data
80ppm increase -- took 50,000 years
110ppm increase -- 25,000 years
120ppm increase --- 20,000 years
60ppm increase --- 20,000 years
90ppm increase --- 15,000 years
100ppm increase --- 24,800 years
The numbers for 800,000 years would be similar, based on a graph, from ice core data going back that far.
