GLACIAL SYSTEMS

 

TASK

  1. Read the text above and annotate the pdf with information about glacial systems

 

 
 

Why does climate change?

Glaciers advance when inputs exceed outputs, when there is more accumulation of snow in the winter than melting of snow in the summer.

But what are the historic reasons for changing climates? What causes warmer and colder years? Human-induced climate change plays an important role in the current warming period, but natural, astronomical factors are also responsible for historic changes in climate.

Read the excerpt from "Africa: A Biography of the Continent" by John Reader and make notes on the three astronomical causes of climate change.
