Meet Sir David Attenborough.
He is stood on a graph that
shows three models of climate
change:
• Natural induced Climate
Change
• Human induced Climate
Change
• Natural and Human
induced Climate Change
TASK: Which colours do you
think represent the above
models. There are 3 colours
and 3 models.
LO: To explore the evidence of climate change during the quaternary
period.

What is Climate Change?
Climate change is the long-term change in weather.
Global climate change occurs very slowly over
thousands of years.
Write your own
definition of climate
change in your books.

The Quaternary Period
The Earth is believed to be 4.55 bn years old
and so studying the Earth has led us to
devise a geological timescale that divides
Earth’s history into a series of eras, periods
and epochs. The period of timeline that
spans from 2.6 million years ago to the
present day is called the Quaternary Period.
This period marks a time when there was a
global drop in temperature and the most
recent ice age began. It is thought that there
have been 5 ice ages in Earth’s history.

MARK SCHEME:
Any two from:
ice cores (1) can be used to measure past temperatures and gases in
the atmosphere and compare this to todays (1),
global temperature increase (1) the earth has warmed up 1⁰C in the
last 100 years (1),
sea level rise (1) caused by thermal expansion or melting ice (1),
glacial retreat/melting ice (1),
artic sea ice has thinned by 65% since 1975 (1).
