A Different Perspective Of The Rise In Global Temperature

I’ve moved to WordPress.  This post can now be found at A Different Perspective Of The Rise In Global Temperature

###################
Figure 1 is a time-series graph of Global Temperature Anomalies (land and sea surface temperature) and linear trend from January 1850 to February 2010. Also listed on the graph is the calculation of the rise in global temperature (0.624 deg C) based on the linear trend over the term of the data. The year-to-year variations from El Nino and La Nina events are visible, as are the multidecadal variations caused by the Atlantic Multidecadal Oscillation. And if you study the last 30+ years of the graph closely, you can note the upward shift in global temperatures in 1976 from what is called the Great Pacific Climate Shift, and you can make out the upward steps caused by the ENSO events of 1986/87/88 and 1997/98.

The Hadley Centre’s HadCET Central England Temperature is included in the KNMI Climate Explorer webpage of Daily climate indices. Figures 2 and 3 show the daily high and low Central England Temperature from 2001 to 2009. Figure 2 presents the data in deg C, and for those who are more familiar with temperatures in deg F, I converted the data to that scale in Figure 3. The annual seasonal cycles are very apparent. Over this period, the highest temperature was 32.9 deg C (~91 deg F), and the lowest temperature was -7.3 deg C (~19 deg F), balmy by some standards. Note the red line.

THE WIDTH OF THE RED LINE EQUALS THE RISE IN GLOBAL TEMPERATURES (0.624 deg C or 1.123 deg F) FROM 1850 TO 2010 BASED ON THE LINEAR TREND IN FIGURE 1.

And yes, I got the idea for this post from an illustration used by Dr. Richard Lindzen in many of his presentations. A YouTube version of Dr. Lindzen’s November 17, 2009 lecture at Oberlin College follows.
