Original sentence: According to Ward, Lawson provided no evidence to back his claim which is, said Ward,  contrary to satellite measurements and he similarly incorrectly implied that the correlation between CO2 and sea levels was uncertain as sea levels were rising more slowly since 1950 than before it.According to Ward, the current sea level rise is accelerating.In fact, said Ward, the IPCC Fourth Assessment Report estimates living standard will rise by a factor of 66 but crucially makes no assessment of how it will be affected by climate change.Ward also criticised Lawson for repeating in a 2010 BBC radio debate that Antarctic ice volumes were unchanged even after this alleged error was highlighted by his opponent, Professor Kevin Anderson.Ward claimed that the Charity Commission should review the GWPF in light of the equirement that statements by campaigning charities "must be factually accurate and have a legitimate evidence base"
