Climate data amid CO2 protest march
Updated on 05 December 2009
As thousands march to demand carbon emission cuts at next week's Copenhagen summit, the Met Office is to publish its historical data on climate change. Andy Davies reports.
Today tens of thousands of people marched through London, urging the summit to agree a workable and binding deal on cutting carbon emissions.
It comes as the Met Office is to publish weather data going back 160 years, which it says shows global warming is caused by humans.
It will be a key source for the Intergovernmental Panel on Climate Change - a crucial part of next week's Copenhagen summit.
Skeptics claimed this week that leaked emails showed researchers had manipulated evidence to back theories of man-made climate change.
