the next solar cycle And why it matters for climate

Understanding the 11-year solar cycle is important, not just for the science of the Sun, but also for appreciating and predicting its influence on Earth and its climate.

From the study:

2019 was mostly without sunspots. For a long period, the Sun was spot-free for 90% of the time, making the period of minimum activity at the end of Solar Cycle 24* and the beginning of Cycle 25 one of the deepest solar minima ever observed. Understanding the 11-year solar cycle is important, not just for the science of the Sun, but also for appreciating and predicting its influence on Earth and its climate. The Sun is changing its behaviour, and is not acting the same way as it did 50 years ago, when solar cycles were stronger than they are today. How significant is this change? Could the solar cycle behaviour be about to influence the Earth’s climate, as some think may have happened 350 years ago?
