Ideally, we'd like short time spans so we can read them more easily, but how about that upward spike at ~340,000 years? This is just calibrated eyeball, but it looks like it goes up 9 or 10 degrees in 3/32" on my screen while that horizontal scale is 133,000 years/inch. I couldn't find a decimal ruler. 133,000 * (3/32) = 12,468.75 years.
Ussing the 10 degree estimate, that gives us a rate of 1 centigrade degree every 1,247 years.
Doing the math, we get 0.0802C/century.
The rate since 1850 is 1.2C in 173 years or 0.6936C/century.
0.6936 / 0.0802 = 8.65. So the current warming rate (conservatively taken from 1850 to the present) is 8.65 TIMES the rate in that dramatic glacial warming spike. The rate since 1981 is listed as 1.8C/century. That would be almost 22.5 TIMES that interglacial rate
