\u201cUntil now, the origin of the climate dynamics of the Central Andes during the last millennium has been speculative. On the basis of statistical evidence, we have identified solar variability as its origin.\u201d \u2013 Schittek et al., 2025<\/strong><\/h4>\n\n\n\n

<\/p>\n\n\n\n

In a new study<\/a><\/strong>, scientists have determined:<\/p>\n\n\n\n

1) The Little Ice Age (LIA) was a global-scale cold event.<\/p>\n\n\n\n

2) Southern Hemisphere (Peruvian Andes) climate (precipitation) variations are robustly linked to variations in solar activity over the last 1,000 years.<\/p>\n\n\n\n

3) The modern (1900s-2000s) and Medieval Climate Anomaly climate warmth are associated with reduced rainfall, and the LIA colder temperatures are associated with more precipitation.<\/p>\n\n\n\n

\u201c\u2026the LIA was a global event, marked by advance of glaciers worldwide.\u201d<\/em><\/p>\n\n\n\n

\u201cSolar irradiation is the primary driver for all climate circulation processes on Earth. Evidence for a direct solar influence on the Earth\u2019s climate has been growing.\u201d<\/em><\/p>\n\n\n\n

\u201cOur study reveals evidence that precipitation changes in the south-eastern Peruvian Andes are linked to variations in solar activity during the LIA [Little Ice Age].\u201d<\/em><\/p>\n\n\n\n

\u201cSeveral studies attribute climate cooling during the LIA to solar forcing, particularly during the Wolf, Sp\u00f6rer, Maunder, and Dalton Minima.\u201d<\/em><\/p>\n\n\n\n

\u201cThe position of the ITCZ [Intertropical Convergence Zone] is robustly dependent on the interhemispheric temperature gradient triggered by solar forcing.\u201d<\/em><\/p>\n\n\n\n
