Climate Scientist Dr. Chris de Freitas: ‘Current warm phase…is not unprecedented’ — ‘From the results of research to date, it appears the influence of increasing CO2 on global warming is almost indiscernible. Future warming could occur, but there is no evidence to suggest it will amount to much’
'Whatever the cause of the current warm phase, its occurrence is not unprecedented. Global warming happened from 1850 to 1940, then cooling to 1979. During the Medieval Warm Period from 900 to 1200AD, the Vikings sailed in arctic waters that are now covered with sea ice, and farmed Greenland soil that is now too cold for agriculture'
