Title: What are the effects that rapid climate change may have on our environment?

Learning objective: To develop an understanding of some of the potential outcomes of climate change.

How will I achieve today’s learning objective?

All Students: Will understand that the temperature of our climate does vary over time. Most Students: Will be able to describe some of the results of the current trend of rising global temperatures. Some Students: Will start to think about the wider implications of this, and consider the effects that humans are having on the wider environment.

Global temperatures since the end of the last ice age (10,000 years ago) have fluctuated with warm and cooler periods

Overall the temperature over this period has increased by around 6°c

Using the graph on the following slide can you describe the changes in temperature over

time, step by step

1. After the last ice age the temperature rose rapidly for the following 2,000 years

2. Between 4,000 and 8,000 years ago there were two warm periods with a temperature change between 5 and 6°c

3. In between these warm periods there was a colder spell

4. Another warm period happened between AD800 and AD1200, this was known as the medieval warm period

5. After all of this there was then the Little Ice Age where temperatures dropped below the average for 600 years

6. In the past 100 years the temperature has begun to rise steadily, with greater increases since the 1960s

7. The temperature is projected to increase much more rapidly in the coming years, being 5°c warmer in 2100 than it is now!

Climate PredictionsClimate change predictions vary, with some people claiming that global warming isnt happening at all !

Climate PredictionsHowever, it is now widely accepted that earth is warming.
