Climate Change: Snow and Ice

Question for Department for Business, Energy and Industrial Strategy

UIN 66792, tabled on 7 March 2017

To ask the Secretary of State for Business, Energy and Industrial Strategy, what information he holds on whether there are declines of snow or ice, other than of Arctic sea ice extent, that are inconsistent with reasonably expected natural variability.

The Department for Business, Energy and Industrial Strategy has not made its own assessment of the above question.

Evidence that present rates of decline in the extent of Arctic sea ice are not consistent with reasonably expected natural variability is synthesised in the 5th Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR5). Long-term records of Arctic sea ice extent in this report show that the decline from 1980 onwards lies outside of what would be expected from natural variability alone. IPCC AR5 reports high confidence that human influences are very likely (>90% probability) to have contributed to the observed Arctic sea ice loss since 1980.
