Influence of solar and cosmic-ray variability on climate

TL;DR

This study investigates how variations in solar activity, geomagnetic, and cosmic ray fluxes influence climate patterns, revealing significant correlations with rainfall and temperature changes over multiple solar cycles.

Contribution

It provides new evidence linking solar and cosmic-ray variability directly to climate fluctuations, supported by analysis over five solar cycles.

Findings

Higher solar activity correlates with increased rainfall and higher temperatures.

Decreasing cosmic ray intensities associate with reduced rainfall and cooler temperatures.

The study proposes a plausible mechanism connecting solar variability to climate change.

Abstract

We analyze solar, geomagnetic and cosmic ray flux data along with rainfall and temperature data for almost five solar cycles. We provide evidence of significant influence of solar variability on climate. Specifically, we demonstrate association between lower (higher) rainfall and higher (lower) temperatures with increasing (decreasing) solar activity and decreasing (increasing) cosmic ray intensities. We propose a plausible scenario that accounts the results of our analysis.
