Climate change: politics or science?
The consensus among climate scientists is that human activities that increase concentrations
of greenhouse gases in the atmosphere are responsible for recent increases in the
global mean temperature. In response to this, the Intergovernmental Panel on Climate
Change (IPCC) was established to produce reports on the knowledge of climate systems.
IPCC predictions are that temperatures will continue to increase and effects will
include rising sea levels, extreme weather events, retreating glaciers and icecaps,
a decrease in oceanic thermohaline circulation, and increased pests and diseases.
However, there are climate sceptics who disagree that human activities are responsible
for the observed increases in temperatures. They argue that natural systems are
responsible for observed changes, and that the IPCC predictions are exaggerated
and inaccurate.
Research was carried out during 2005 to review the findings of various climate sceptics
and whether their argued points concerning climate change are valid.
