There are potentially two effects to consider. Both of which could be too small in this particular case to make a difference.
1) The shading and GH gas effects of the aerial admissions (both gaseous and particulate.
2) The large sudden freshwater release from melting ice, which appears to be causing some significant flooding at this time.
At least one time in the distant past enough freshwater (from melting glaciers) suddenly entered the northern ocean causing disruption of the primary ocean currents, which in turn caused a mini ice age.
So there has been a concern that as glaciers melt there would be large lakes of cold fresh water dammed up behind "ice dams". With a catastrophic release of the dammed up water a huge influx of cold fresh water would dump into the ocean and stop or reverse the direction of the prevailing oceanic current (which ultimately controls global weather patterns).
