Instead all we get are graphs that show temperature anomaly. And the anomaly is from what? What is the "normal" Earth temperature that they are using to measure for the anomaly?

I can't find that either. We just get a graph that is zoomed up big to make 1/2 of one degree look huge when compared to the lower temp which was 1/2 of one degree anomaly below whatever temp it is they are using as "normal"
Exactly. There is no "set" temperature for the Earth and out of the range of known temps that the planet has experienced we are currently closer to the bottom end of the range. The planet, humans and civilization have survived periods of much warmer temps than we have now. This supposed goal of a two degree decrease will return us to conditions of the LIA and do much more damage than a two degree increase.

The anomaly graphs are almost meaningless because .5 degrees is just about the margin of error for terrestrial based temperature data. Besides that there is not sufficient global coverage of reliable ground-based temperature data collection. Over half of it is guess work and predictions based on models that are faulty to begin with.

On top of that NASA and the NOAA have been adjusting the ground-based temperature data record to effectively cool the past and warm the present. Most of the current data is meaningless because it is basically made up.
