Climate change is considered by many to be the world’s greatest problem (technically a context hazard); and so a chronic, large-
scale threat to people. Uncertainty about its impact is inevitable as scientists struggle to make firm predictions. It is an unfair
world in which the wealthiest countries have emitted most of the greenhouse gases and the poorest ones are most vulnerable to
their impacts. This topic poses questions about the causes of global warming, its relationship to long-term climate change, and the
direct and indirect impacts that result. It also considers some of the solutions, whether global or local, and the complexity of
managing international concerns against a background of national and personal self-interest. It also provides suggestions for
tackling a variety of global hazards.


4. CLIMATE CHANGE AND ITS CAUSES


Enquiry Question - Is global warming a recent short term phenomenon or should it be seen as part of longer term climate change?

The current phenomenon of global warming should be set in the context of longer, medium and short term climate change. A range of
evidence from ecology, historical records and climate change should be reviewed.

What evidence do we have for climate change in the past?
  • warming oceans
  • global temperatures rising
  • sea levels rising
  • glacial retreat
  • shrinking ice
  • declining arctic ice
  • acidification of the oceans
  • extreme events

What are the historical causes and the role of human activity
Historical evidence for climate change

How it all ends

The cause of Climate may be both natural and human (anthropogenic)

Recent Climate Change (global warming) is unprecedented in historical terms and scientists now argue that human causes may be more to blame.

5. THE IMPACTS OF GLOBAL WARMING

Inquiry Question - What are the impacts of climate change and why should we be concerned?

The Arctic sea ice coverage has shrunk considerably from 1979 to 2003 and so reduces the amount of solar radiation reflected back into space from the earths surface.
