The following table is the kind of data I think will be useful to have after the pole shift. So far I can think of 4 ways that one can measure approximate
latitude after the pole shift under thick cloud cover. These are dip needle, average temperature, use of an amateur radio telescope to track the sun, and
length of daylight (twilight to twilight). The most useful is to find average expected temperature by measuring latitude first by using one of the other
three approaches. Information on weather and average temperature that one can expect at different Latitudes is available.
I plan to present this sort of data graphically, that is if we can not find it already done. To do a good job I think we need more data points. If anyone has a good reference that might help please share it. I found the concept of latitude versus temperature to be popular for 5-12 grade school projects. There is a lot of description on what to do but not much on what has been done or found as a result. So for me the bottom line is, it's back to a 5th grade project to learn what I didn't learn when I went through school.
