Recent Global Temperature Rise Same as 1910-1945

This is so very important! This graph, click to enlarge, is plotted from the monthly mean of surface temperatures from 1910 to present, found here. During about 1910, world temperatures began to rise as we came out of The Little Ice Age. The graph was created here, and you can move the date back to 1880 to see that the rise did not really occur until 1910. I plotted a trend line for two periods of rising temperatures. One before mans CO2 emissions were significant and one after. Understand that the Alarmists state that man's CO2 emissions only really increased since the industrial age began in 1940. No Alarmist is claiming the temperature rise from 1910 to 1945 is from man, it is agreed the rise in temperature was due to natural causes and fluctuations. The alarmists claim that the rise in temperature that began about 1975 through the present is all from man's CO2 emissions. They also claim that the recent stabilization of temperatures, discussed in the post below, is from natural fluctuations. But how could the 35 run up of temperatures from 1910 to 1945 be natural and the same 35 year rise from 1975 to 2009 is anthropogenic, ie. man-made?
