The POT has gone out to clarify that there is no imminent “ice age” or “mini ice age” caused by an expected reduction in production of energy from the Sun in the coming decades.

Throughout its useful life, the Sun naturally undergoes changes in energy production. Some of these occur over a period normal 11-year peak (many sunspots) and low activity (less sunspots), which are quite predictable.

But sometimes, the sun becomes quieter, it experiences much less sunspots and emits less energy. This is called a “Great Solar Minimum,” and the last time this happened, it coincided with a period called the “Little Ice Age”: a period of extremely low solar activity from about 1650 to 1715 in the northern hemisphere, when a combination cooling of volcanic aerosols and low solar activity produced lower surface temperatures.

Some scientists have suggested that the relatively small magnitude of the last solar cycle heralds a new Great Solar Minimum in the coming decades. Regarding its effect in terms of climate forcing, A factor that could propel climate in a particular direction, solar scientists estimate it would be approximately -0.1 W / m2, the same impact of approximately three years of current growth in carbon dioxide (CO2) concentration.


Thus, a new Great Solar Minimum would only serve to compensate a few years of warming caused by human activities, NASA specifies in its blog Ask Nasa Climate.

Even if a Great Solar Minimum will last a century, global temperatures will continue to heat up. Because more factors than just variations Global production on Earth changes in the production of the Sun, the most dominant of which is today the warming from emissions of effect gases human-induced greenhouse.
