Sun’s Fading Spots Signal Big Drop in Solar Activity

Sun’s Fading Spots Signal Big Drop in Solar Activity

Some unusual solar readings, including fading sunspots and weakening magnetic activity near the poles, could be indications that our sun is preparing to be less active in the coming years.

The results of three separate studies seem to show that even as the current sunspot cycle swells toward the solar maximum, the sun could be heading into a more-dormant period, with activity during the next 11-year sunspot cycle greatly reduced or even eliminated.

The Maunder minimum, or Landscheidt Minimum as perhaps it should be called looks set to be with us over the next 4 or 5 decades – long enough to see me into a colder than normal grave I think.

In many ways I am lucky as I don’t feel the cold as much as some people do and I feel for those for whom cold is a painful experience.

“We expected to see the start of the zonal flow for Cycle 25 by now, but we see no sign of it,” Hill said. “The flow for Cycle 25 should have appeared in 2008 or 2009. This leads us to believe that the next cycle will be very much delayed, with a minimum longer than the one we just went through.”

Hill estimated that the start of Cycle 25 could be delayed to 2021 or 2022 and will be very weak, if it even happens at all.

Not taking a pop at the AGW crowd (er, yes I am) but I read in some article yesterday that they ‘don’t think the effect will be more than 0.3 deg C when AGW is taken in to account’.

One has to wonder just what ‘models’ they use for these preposterous statements. The Earth was very chilly back then. You only have to read some of the accounts of the time to know that it most certainly was not the 1 deg C that the AGW crowd say it was.

The impact of the solar minimum is clear in this image, which shows the temperature difference between 1680, a year at the center of the Maunder Minimum, and 1780, a year of normal solar activity, as calculated by a general circulation model. Deep blue across eastern and central North America and northern Eurasia illustrates where the drop in temperature was the greatest. Nearly all other land areas were also cooler in 1680, as indicated by the varying shades of blue. The few regions that appear to have been warmer in 1680 are Alaska and the eastern Pacific Ocean (left), the North Atlantic Ocean south of Greenland (left of center), and north of Iceland (top center).

I have little doubt that the warmists will still be peddling their wares in 25 years time, wrapped up in several layers of Arctic clothing and still saying the world is warming up. I hope I am still around to laugh at them.
