The last glacial maximum occurred roughly how long ago?

  • A.about 20 thousand years
  • B.about 2 thousand years
  • C.about 200 thousand years
  • D.about 2 million years

Answer: A

Correct answer: about 20 thousand years

The last glacial maximum was around 20,000 years ago, when ice sheets reached their greatest extent and sea level stood about 120 metres below the present. It is the best documented cold state available, which is why it is used so heavily as a test case for climate models - the forcings are reasonably well known and the response is large.
