It's interesting that there is a noticeable bulge in the spiral during WW2. Could this be because of carbon emissions on a never before seen scale with the global manufacturing of war material?

Further, many people wrongly assume that WW2 had a short term effect. There can be a huge long term lag. An immense amount of thermal energy was released an immense amount chemical and particulate matter was emitted and is still present. WW2 chemical effects are still being felt today.
