The author writes in his 40-page document: ‘This report is not meant to be an exhaustive representation of all the published papers related to a solar influence on Earth’s climate, but aims to give a clear presentation of the current knowledge on the link between solar activity and climate.’

Where does cosmic ray variation fit into the ‘big picture’ of solar influences on the Earth?

I am still studying this paper but wanted to share and get your feedback

Executive Summary

Over the last twenty years there has been good progress in understanding the solar influ- ence on climate. In particular, many scientific studies have shown that changes in solar activ- ity have impacted climate over the whole Holocene period (approximately the last 10,000 years). A well-known example is the existence of high solar activity during the Medieval Warm Period, around the year 1000 AD, and the subsequent low levels of solar activity during the cold period, now called The Little Ice Age (1300–1850 AD). An important scientific task has been to quantify the solar impact on climate, and it has been found that over the eleven- year solar cycle the energy that enters the Earth’s system is of the order of 1.0–1.5 W/m2. This is nearly an order of magnitude larger than what would be…
