Solar Storm 2025 Effects On Climate. As we approach the peak of solar cycle 25, we should expect to see more sunspots, each of which is a region of intense magnetic activity capable of producing solar flares and coronal mass ejections, or cmes. Solar maxima usually lasts between two and three years.

As we enter a period of increased solar activity, known as solar cycle 25, we can expect more geomagnetic storms in the coming years. Originally, scientists predicted that the current solar cycle would peak in 2025.
