“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.
A Seminal New Paper Unveils The ‘Cause Of Causes’ Of Climate Change
Norwegian professors Harald Yndestad and Jan-Erik Solheim have asserted in their groundbreaking New Astronomy paper that the modern (1940-2015) Grand Maximum of very high solar activity — the highest solar activity levels in 4,000 years — has just ended. Within 10 years, or by 2025, these scientists project the next solar minimum period (which will be similar in character to the late 18th Century’s Dalton Minimum) will exert its cooling effect on the Earth’s climate.
Yndestad and Solheim have been working together on this project for more than 2 years, and although Dr. Yndestad was “skeptical about the idea of sunspots as climate indicators” initially, the two discovered “for the first time” a strong long-term correlation between Total Solar Irradiance (TSI) and sunspots for periods of 84 and 210 years, confirming the “Cause of causes” of climate change. Details can be found in their illuminating new paper.
