tried to see what average temperatures were during little Ice Age in England

Trends revealed by the Central England temperature...

I took the temperatures from around 1700 and the temperatures (today?) in the above dataset trend graph and this is what I got:

Average temperature around 1700= 8.2 celsius or 46.76 Fahrenheit during little ice age
Average low temperature around 1700= 7.3 Celsius or 45.14 Fahrenheit

Today from the above word button graph I got:
10.2 Celsius for average temperature which = 50.38 Fahrenheit
and
8.9 Celsius for average low temperature which = 48.42 Fahrenheit

If I then take how much lower this average in 1700 was from today it was:

If I did this right it is 10.076 percent less temperature in 1700 than today for the average
temperature in 1700.


And if I subtract 7.3 from 8.9 this is a  16% percent lower low than now.


So, only in theory might this work in the northern Hemisphere but  it might be useful to take your average present temperature year around and deduct 10.076 percent from it for average temperature.

and/or subtract 16% from your average lows to see what your area would be in another little ice age which might be here in 2030 for 30 or 40 years through the Maunder Minimum during that time of the sun. Since I did this using Celsius likely these percentages would work whether you are using Celsius or Fahrenheit.

Also, this is an estimate to try to see what a little ice age might do various places in the northern Hemisphere starting around 2030 if that happens. However, if the Maunder minimum comes on time you will know it because there will be NO aurora Borealis or Northern Lights likely for 30 or 40 years during the Maunder Minimum.

I was thinking about what might happen if an El Nino like we are presently experiencing happened the same time as a Maunder Minimum. If you wanted to know draw a line along the U.S. where freezing would occur at least 12 hours during any 24 hour cycle to understand just how much rain would turn to snow on the way to the ground from about October or November until the following May or June.
