This graph was shown on TV by Professor Brian Cox during a programme about Climate Change. He put it forward as proof of Climate Change. It is a well known NASA graph (its on their site). It is well known for being fake shit. To Climate Change protesters this is part of the Holy Grail of ‘facts’. It was produced sometime after 2008.
This is the ‘original’ also on the NASA site. It was produced before 2008. Don't just believe me look it up!
