S. African Scientist Kelvin Kemm: Glacier melting is not caused by global warming: ‘To melt ice, the temperature has to go up past 0 ºC to at least ‘plus something’

‘Research on various glaciers of the n. & s. hemis- pheres has shown that most of them started their retreat in the mideighteenth century…’

‘These results suggest that climatic changes in the world started during the early to the mideighteenth century.’ This is long before the historical increase in the air’s carbon dioxide (CO2) content could have been involved in the process of their retreat. Hence, it must be concluded that there is no compelling reason to believe that late-twentieth- century global warming has anything to do with glacial retreat.’
