“It is generally accepted that the climate warms during periods of strong solar activity (e.g., the Medieval Warm Period) and cools during periods of low solar activity (e.g., the Little Ice Age).” — Lyu et al., 2016

Scientists are increasingly tuning out the claims that the Earth’s temperatures are predominantly shaped by anthropogenic CO2 emissions, or that future climate is destined to be alarmingly warm primarily due to the rise in trace atmospheric gases. Instead, solar scientists are continuing to advance our understanding of solar activity and its effect on the Earth system, and their results are progressively suggestive of robust correlations between solar variability and climate changes.
For example, in 2016 alone, there were at least 132 peer-reviewed scientific papers documenting a significant solar influence on climate. Among them there were 18 papers that directly connected centennial-scale periods of low solar activity (the Little Ice Age) with cooler climates, and periods of high solar activity (the Medieval Warm Period and the Modern Warm Period [20th Century]) with high solar activity levels. Another 10 papers warned of an impending solar minimum and concomitant cooling period in the coming decades.
And this trend of scientists linking climate changes to solar forcing mechanisms — and bypassing an anthropogenic explanation — continues to rage on in 2017.
