2.1 Climate Science
According to the Intergovernmental Panel on Climate Change's (IPCC)
Third Evaluation Report (2001), the global mean annual temperature
may increase by as much as 5.8 degrees centigrade by 2100. Globally
the 1990s was the warmest year in the instrumental record since
1861 and analysis of proxy data for the Northern Hemisphere indicates
that the increase in the 20th century is likely to have been the
largest of any century during the last 1000 years. Global average
sea levels have risen and ocean temperatures have increased. Snow
cover and ice extent are receding. While there are natural variations
in climate, the IPCC believes that "emissions of Greenhouse
gases and aerosols due to human activities continue to alter the
atmosphere in ways that are expected to affect climate". (1)
The IPCC's assessment is the most rigorous of any
assessment of climate change. The report cited above involved the
participation of 99 IPCC member countries, 122 Lead Authors, 516
Contributing Authors, 337 Reviewers and 21 Review Editors. (2)
Value at Stake
The impact of climate on society and the economy
and on individual businesses is fundamental although not always
acknowledged. Almost every business is impacted by the weather directly
or indirectly through their value chain. The impacts of extreme
weather are obvious however more subtle changes can also have a
huge impact.
For example from October 1994 to November 1995 England
and Wales experienced an average temperature increase of just 1.5C.
Farmers lost £180 million, electricity generators £355
million, clothing retailers £380 million and insurance lost
£350 million due to drought-induced subsidence. In August
1995 England's human mortality rate increased by 5% due to warmer
temperatures. (3)
The value at stake from an unstable, unpredictable
climate where deviations from the "norm" become normal
and extreme weather events become more frequent and intense has
a variety of impacts on business. These can include demand, sales,
revenue, cash flow, turnover, productivity/efficiency, outages,
damage, accidents, staff well-being, product quality and durability
amongst others.
