The report's co-author, Prof Corinne Le Quere, director of the Tyndall Centre for Climate Change Research and professor at the University of East Anglia, says, «Global CO2 emissions since 2000 are tracking the high end of the projections used by the Intergovernmental Panel on Climate Change, which far exceed two degrees warming by 2100.
