Lets just watch this month by month and keep it real. Bigdave will certainly oppose this approach.
What a mess. These aren't "lower atmosphere" temperature measurements.
You couldn't use this data directly as none of the satellites that you posted the graph from actually even measure the lower atmosphere, but the "middle troposphere" which some folks have derived what they think the lower atmosphere might measure -- and even then has a significant amount of sample noise.
So you've taken the output from three satellites, then altered them to derive what the lower atmospheric temperature might be, with each satellite having a good sized error since they don't measure the lower atmospheric temperature, and averaged the derived "measures" with noise all together and put them in a graph marked "satellite based temperature."
Here's an explanation of the mess you've made:

Beyond that, this also doesn't work just as you can't tell if the yearly average for the stock market is going to be up by picking one month.
