It doesn't look like anything to me.
So, if we've been witnessing a drop in observed temperatures, perhaps TPTB are actually doing something about it.
The quote was that we have been observing a global drop in land temperatures since the middle of the year. There is far more land in the northern hemisphere than the southern which means seasonal effects will not balance out. So rather than evidence of geoengineering I'd just take this as a sign that winter is coming.
This place just isn't big enough for all of us. We've got to find a way off this planet.
