Tracking down climate feedbacks

Update  26/4:  The feedback should really be calculated by the ratio DT1/DT2 = 1-g0F. Applying this for the full period of CRUTEM4 data 1900-2005  the value derived for F= -1.5+/- 0.8 Wm-2K-1. I have been studying differences in climate data … Continue reading

CRU’s Arctic fix

How 2005 & 201o got “ranked” the warmest years. The new temperature data from  CRUTEM4 has added 628 new weather stations, including strangely enough over 50 from Kyrgyzstan. Most  of these stations are in far northern latitudes. There are none in … Continue reading

Temperature trends map

The map below shows the geographic distribution of post 1990 temperature trends derived from station data contributing to HadCrut3 global temperature anomalies. The Had/CRU anomalies are relative to the period 1960-1989 so they all measure warming/cooling relative to that baseline. … Continue reading
