Nice chart. I generally do not think that looking at temperature readings in Arctic Polar regions gives a good REAL TIME trend evaluation. Primarily because there is probably a significant delay between equatorial (tropical/subtropical) solar flux levels and the resulting air and water temperature in the polar regions. Mid Latitudes are probably more accurate in determining current trends. However, the problem with mid-latitudes and equatorital regions are that temperature sensors in those areas tend to be located within urban heat areas. Historically preserved readings from the Arctic should theoretically be less affected by urban heat island affects.
Concerning the future sunspot activity, NASA is predicting that Solar Cycle 25 (cycle 24 is just starting) will be a very weak cycle based on measured plasma belt current velocities. So 2020-2033 should see very low solar activity. Ironically, solar cycle 24 looks to also be starting late and weak. Coincidently we just had a cold winter in the Southern Hemisphere and in many areas of the Northern Hemisphere this currently looks to be a cold winter. I am living in the Los Angeles area but the weather here has been what Seattle normally experiences. China right now is trying to keep people warm and is running low on mined coal.
