Global temps being readjusted to show warming not previously seen?! ‘HADCRUT4 is the new Met Office dataset designed to replaced HADCRUT3’
'Why do they need to replace HADCRUT3? Because the trend for last 15 years in HADCRUT3 is negative & therefore it must be exterminated – like Medieval Warm Period' -- 2) For some reason, after 2002, there appears to be corrections of .1 to .2C. Why was data ok in 1997-2002 & suddenly it was so bad it had to be 'corrected'. 3) What justifies a .2C adjustment up in 2007? Thats 40% higher! 4) ...they have adjusted up to make the the 'new dataset' hotter'
