Question 1

solar output

Answer 1

intense flares of solar radiation leave the suns surface - these coincide with high levels of sun spot activity

the Medieval Warm Period (900 -1300) was connected to intense sun spot activity

sun spot activity happens every 11 years

- the average temp was between 0.5 and 1 degree cooler than it has been since 1900
- scientists believe it was to do with sunspot and volcanic activity

Question 4

effects of little ice age

Answer 4

thames froze
- glaciers (alpine) avanced rapidly causing evacuation of many settlements
- crop harvest were reduced because of shorter growing season so food supply became strained
