Met Office to re-examine 160 years of climate data
The Met Office plans to re-examine 160 years of temperature data after admitting that public confidence in the science on man-made global warming has been shattered by leaked e-mails.
The new analysis of the data will take three years, meaning that the Met Office will not be able to state with absolute confidence the extent of the warming trend until the end of 2012.
The Met Office database is one of three main sources of temperature data analysis on which the UN’s main climate change science body relies for its assessment that global warming is a serious danger to the world. This assessment is the basis for next week’s climate change talks in Copenhagen aimed at cutting CO2 emissions.
The Government is attempting to stop the Met Office from carrying out the re-examination, arguing that it would be seized upon by climate change sceptics.
The Met Office’s published data showing a warming trend draws heavily on CRU analysis. CRU supplied all the land temperature data to the Met Office, which added this to its own analysis of sea temperature data.
