The Global Warming Polilcy Foundation (GWPF) was launched by Lord Lawson, the former Chancellor of the Exchequer, last week to "help restore balance and trust" in the climate change debate.
The think tank was set up in the wake of the 'climategate scandal' that saw scientists at the University of East Anglia's Climatic Research Unit (CRU) accused of manipulating climate change data.
However it has now emerged that a graph used by the GWPF on its website was incorrect.
The graph, that shows global temperatures from 2001 to 2008, showed 2003 was the hottest year when in fact it was 2005.
The organisation have admitted there was a "small error" and have now corrected the graph.
However climate change scientists were quick to accuse the GWPF of double standards.
