1. The Little Ice Age coincided with a period of low solar activity known as the Maunder Minimum.
2. During the Little Ice Age, sunspot numbers were significantly reduced, indicating lower solar output.
3. Volcanic activity during this period contributed to global cooling by releasing aerosols that reflected sunlight away from Earth.
4. Lower temperatures during the Little Ice Age led to harsher winters and shorter growing seasons in many parts of the world.
