The wikipedia chart covers 450 thousand years on the x-axis, and a 14 degree range on the y-axis. Your chart covers 12 thousand years on x and 2 degrees on y. If your chart was shrunk to the same scale and overlaid on the first chart, it would be lost in the noise, and your astounding gradient would be nothing compared to the rises and falls 20K and 140K years ago, among others. Very disingenuous of you.
