HC Deb 12 December 2002 vol 396 cc454-5W
Norman Baker

To ask the Secretary of State for Environment, Food and Rural Affairs if she will make a statement on the historical data which she collates on snowfall; and what the predicted future annual number of days when there is snowfall are for(a) London and (b) Edinburgh in (i) 2010, (ii) 2020, (iii) 2030 and (iv) 2050.

Mr. Meacher

Defra does not collate historical data on snowfall. However, the Met Office, which is an agency of the Ministry of Defence, records daily snowfall frequency and amount at 80 stations in the UK. Most of these records go back to 1971. In April this year, the Department published new climate change scenarios for the UK. These scenarios include information on total winter snowfall amounts, but not number of snowfall days. The scenarios show that snowfall in the London and Edinburgh areas could be reduced by between 55 and 90 per cent. by the 2080s (compared to the 1961–90 baseline), depending on the degree of future climate change. Scaling these figures back to the years in question gives the following estimates of the reduction in snowfall amount at both locations, depending on whether there is a low or high degree of climate change:

Year Percentage reduction
2010 17–30
2020 22–38
2030 27–47
2050 37–65

These figures represent general trends, not predictions of the amount of snowfall in specific years, which will be greatly influenced by natural year-to-year variability, particularly in the first few decades of the century. Further information is available in the full report in the Libraries of both Houses.

To ask the Secretary of State for Environment, Food and Rural Affairs what recent assessment she has made of the predicted changes in the frequency of the number of days when there is snowfall in the United Kingdom under future scenarios of climate change, including regional variations. [86412]

Mr. Meacher

In April this year, the Department published new "Climate Change Scenarios for the UK". The scenarios do not contain an analysis of the changes in the number of snowfall days, but show that climate change will cause the amount of snowfall to decline significantly throughout the UK in the future. By the 2080s, large areas of the UK are likely to experience quite long sequences of snowless winters. Coastal areas and the English lowlands are likely to show the largest percentage reductions (up to 90 per cent. or more by the 2080s compared to 1961–90 baseline), while the Scottish Highlands and parts of Northern Ireland may experience smaller percentage reductions (50 per cent. or less).

Further information is available in the full report in the Libraries of both Houses.
