Climate Change
What is
Climate Change?
The term climate change refers to the changes
in the world’s atmosphere. It includes a rise in average global
temperature, changes in rainfall and weather patterns. The main
influence on global climate is the emission of greenhouse gases
such as carbon dioxide (CO2)
and methane. These emissions can occur naturally through processes
such as digestion, decomposition and volcanic
eruption. However, anthropogenic (man made) emissions have
increased markedly over the past century. As well as releasing
carbon that has been stored under the ground for millions of years
in the form of coal and oil we have depleted and continue to
deplete carbon sinks such as forests and peat bogs. As a
result the proportion of carbon that is stored in the atmosphere
has increased. Furthermore, the residency time of a carbon particle
in the atmosphere is between 50 to 100 years which means that the
current concentration of carbon in the atmosphere is unlikely to
reduce until the end of this century even if carbon emissions are
reduced now.
Climate effects
The effect of this increased concentration is to raise the
average temperature of the earths atmosphere, surface and seas.
This is called global warming. As the atmosphere heats it becomes
more dynamic, like a pan of water as it boils. This is why one
effect of global warming is more severe weather events like
flash flooding and severe winds. The more dynamic weather is also
more difficult to predict resulting in a large degree of
uncertainty in climate predictions.
Rising air and sea temperatures cause melting of glaciers and
polar ice caps. This extra water flows to the sea causing concern
over rising sea levels. Coastal areas will therefore become more
susceptible to coastal flooding and erosion. Increase carbon in the
oceans results in acidification which damages marine
ecosystems such as coral reefs.
Agriculture is very climate dependant and changes are
anticipated to happen all over the world. Some parts of the world
will suffer drought and crop loss while others will become more
productive. Extreme weather events can damage crops resulting in
uncertainty for farmers and consumers. Some areas of the world may
not be able to sustain the local population anymore so migration
may become an issue as a result of this.
