This document discusses human contributions to global warming and some of the negative effects of climate change. It provides learning objectives about how climate change could impact farming and crop yields, cause sea level rise, and affect glacial retreat. Examples are given of how rising sea levels could impact low-lying coastal areas and islands. The document instructs students to find local examples of impacts from sea level rise in the UK and other countries using provided resources and to identify physical, social, economic and political impacts.

1. Task
• QUESTION: Evaluate human contributions
toward global warming.
• Use the Point, Evidence, Explain (P.E.E.)
method and the template below to construct
your answer.

2. Negative Effects of
Climate Change

3. Learning Objectives
•Explain how a changing climate could affect
farming and crop yields.
•Describe changes in sea level recently and in
the future.
•Know some of the global impacts of sea-level
rise.
•Use an example to show what the impact of
sea-level rise could be locally.
•Know the impacts of retreating glaciers.

4. Negative Effects of Climate Change
• Quiz – think you know about global warming?
• Greenhouse effect video, BBC Bitesize
• The Gaurdian

5. Negative Impacts of Climate
Change
• Changing Patterns of crop yields
– Equatorial countries will suffer a decrease
in crop production due to longer periods of
drought
– Tanzania and Mozambique will have shorter
growing seasons
– India could lose 50% of available
agricultural land due to desertification
– OXFAM
– Expansion of the Sahara Desert

6. Rising sea levels
• UK 5,000 years ago
• Between 1993 and 2006 sea levels
rose by 3.3mm
• If this continues it could result in
88cm by the end of the century
• Low lying coastal areas and cities are
at risk of flooding, including London
• Pacific islands are already being
affected by rising sea levels
• Maldives
• Sea levels map

7. Sea level rise

8. Retreating Glaciers
• BBC Glacial retreat
• Most world glaciers are
retreating, thought to be because of rising
temperatures
• Glaciers at the poles are melting and this
could affect ocean currents
• Arctic melting could divert the Gulf
Stream in the Atlantic, leading to colder
temperatures in northern Europe
• Arctic Sea Ice

10. HOMEWORK TASK
• Use an example to show what the
impact of sea-level rise could be locally.
• The Gaurdian
• Use this website to find an example of what the
impact of sea-level rise would be to the UK
• Use the same website to find an example of one
other country that is will be effected. Describe
how this country will be effected.

11. Negative effects of UK climate change

12. Using UKCIP02 predictions

13. Are there any benefits for the UK?
Warmer temperatures in the UK will be welcomed by many people and may also bring
opportunities:
Tourism may increase due to warmer
temperatures, bringing economic
benefits.
Nice weather may mean people
participate in more outdoor
activities, improving their health.
It may be possible to grow new crops
such as grapes, sweetcorn and
sunflowers.

14. Positive or negative effects?

16. Task: Label the changes on this map

17. Rank them in order of importance
(1=most, 8=least)
In your books:-
Determine any
PHYSICAL, SOCIAL, ECONOMIC and
POLITICAL impacts
