is it possible that our sun is preparing for a catastrophic solar flare? since the sun is already too much ‘overtime’ at the moment and drafts have to expend the same energy (I think). if the sun is so calm in the coming years
does it then continue to cool on the earth or is that canceled out by the greenhouse effect?
Answer
Based on historical data, there’s really no indication that a period of low solar activity is followed by the type of discharge you’re alluding to. After the famous Maunder minimum, the period in the 17th century when the solar cycle came to a complete standstill, the amplitudes of the new cycles have not been particularly large. On the contrary, it only gradually built up again. So it doesn’t really look like it’s scalding in the sun.
And if we look at the climate data on Earth, it seems that the less active sun has not caused a cooling, but rather a stabilization. While the upward trend may have leveled off in recent years, average temperatures remain higher than during the twentieth century. The low solar activity now does not cause a cooling, why should a perpetuation of the effect? Rather than start to be content that ‘apparently things aren’t going so well’, one should fear a renewed rise once the sun sets in motion again.
Furthermore, you are somewhat confusing the global influence of the solar cycle with the incidental effects of solar flares, which are indeed linked to that cycle. The main effect of the solar cycle on Earth’s climate is the average effect of more magnetic influence from the sun, perhaps on the amount of cloud cover on Earth. Solar flares, or rather coronal mass ejections, affect ‘space weather’ more than the ‘weather’. They cause disruptions to air traffic, radio traffic, and sometimes the electricity supply. And ‘catastrophic’ they are only if they happen to have erupted in our direction.
