Century-scale patterns of solar activity suggest the onset of the next Little Ice Age cooling period is here.
Newly published research utilizing historical solar magnetic field phase analysis documents the impact of solar activity on Earth’s temperature.
Cold “Little Ice Age” periods can be reliably linked to Grand Solar Minima (GSM).
For example, during the Maunder Minimum (late 1600s to early 1700s), solar irradiance is thought to have declined by about 3 W/m², and consequently the Northern Hemisphere cooled by approximately 1°C.
Using pattern analysis, it may be assumed that the onset of the next GSM has arrived, and global cooling will be realized over the next few decades.
“During a GSM a reduction of solar irradiance is expected by about 3 W/m² from the modern level that causes a decrease of the average terrestrial temperature by about 1.0C.”
“In summary, it can be concluded that the modern grand solar minimum (2020-2053) predicted 10 years ago by Zharkova et al, 2015 has arrived and will progress as expected until the mid of century. There is the cold weather with huge frosts and snows recorded in January- February 2026 in the whole Northern hemisphere from the West to the East and from the North to the equator. The little ice age associated with the modern grand solar minimum is here…”
