In December 2009, Banksy marked the end of the 2009 United Nations Climate Change Conference by painting four murals on global warming. One included the phrase, "I don't believe in global warming;" the words were submerged in water. A feud and graffiti war between Banksy and King Robbo broke out when Banksy allegedly painted over one of Robbo's tags. The feud has led to many of Banksy's works being altered by graffiti writers.
Some say I am a hustler, some say I am rockstar, some say I am true talent.... With a great personality to boot! Something that all these things have in common... Is that I made an impression...

Murals of sorts date to Upper Paleolithic times such as the cave paintings in the Lubang Jeriji Saléh cave in Borneo (40,000-52,000 BP), Chauvet Cave in Ardèche department of southern France (around 32,000 BP). Many ancient murals have been found within ancient Egyptian tombs (around 3150 BC), the Minoan palaces (Middle period III of the Neopalatial period, 1700–1600 BC), the Oxtotitlán cave and Juxtlahuaca in Mexico (around 1200-900 BC) and in Pompeii (around 100 BC – AD 79).
Among the structures photographed prior to the opening were a large pinwheel by Banksy, Horse Scaffolding Sculpture by Ben Long, and a twisted truck sculpture, Big Rig Jig by artist Mike Ross which was previously shown at Burning Man in 2007.
