The Little Ice Age was a period of wide-spread cooling from around 1300 to around 1850 CE when average global temperatures dropped by as much as 2°C (3.6°F), particularly in Europe and North America.
Cooling happened in phases, with an initial drop around 1300 and an even colder climate starting around 1560 and lasting to 1850.
Temps have gone up & going back to NORMAL....unless you want to stay in an ice age????
Your time line in too short.
