AI Shapiro, W Schmutz, E Rozanov, M Schoell… - Astronomy & …, 2011 - aanda.org
Context. The variable Sun is the most likely candidate for the natural forcing of past climate
changes on time scales of 50 to 1000 years. Evidence for this understanding is that the …

Heliospheric modulation of cosmic rays during the neutron monitor era: Calibration using PAMELA data for 2006–2010

IG Usoskin, A Gil, GA Kovaltsov… - Journal of …, 2017 - Wiley Online Library
