'Climategate' Phil Jones interviewed by BBC
This interview has some pretty amazing points. Jones has spent the better part of the past 25 years toiling to convince the world of CO2-forced 20th-century warming, but now admitting that the difference in warming rates for the periods 1860-1880, 1910-40 and 1975-2009 is statistically insignificant. Jones even acceded that there has been no statistically-significant global warming since 1995; that in fact, global temperatures have been trending to the downside since January of 2002, although he denied the statistical significance of the -0.12C per decade decline.
Jones is now conceding some interesting facts, particularly that this recent warming period might not be particularly unusual.
There is much debate over whether the Medieval Warm Period was global in extent or not. The MWP is most clearly expressed in parts of North America, the North Atlantic and Europe and parts of Asia. For it to be global in extent the MWP would need to be seen clearly in more records from the tropical regions and the Southern Hemisphere. There are very few palaeoclimatic records for these latter two regions.
Of course, if the MWP was shown to be global in extent and as warm or warmer than today (based on an equivalent coverage over the NH and SH) then obviously the late-20th century warmth would not be unprecedented. On the other hand, if the MWP was global, but was less warm that today, then current warmth would be unprecedented. . . .
The UK Daily Mail pointed to these three issues:
Data for vital 'hockey stick graph' has gone missing
There has been no global warming since 1995
Warming periods have happened before - but NOT due to man-made changes
