Every 11 years or so there is a minimum between cycles, a solar minima would be a time period of minimums. Solar science distinguishes the 22 year magnetic cycle minimums/maximums from the periodic multi cycles minimas or maximas.<quoted text>
So we should cool steadily till 2030? Just trying to get it down. BTW, "minima" is plural. I think you meant "minimum" in 2030.
In any case, I believe it's WAY more likely we'll keep warming. We'll see.
Steadily cooling, no more than we've been steadily warming except in the trend. 2008 was a cool year, so if you mean by steadily that each year will be cooler than the last, no, but the trend will be down.
We have learned a lot about solar activity in the last 30 years. The big change has been the recognition of the variability of solar energy. The solar constant, generally accepted at the beginning of the global warming hypothesis, has been shown to not exist.
The amount of impact solar energy has also changed with the 'Pinatubo experiment' we know that small variations in solar energy can cause significant impacts.
It was once assumed that the sun didn't have a pattern of activity that could be discerned. Now with information from many studies we know the sun does have a pattern of activity and that pattern repeats on a variety of cycles.
Here's an interesting comparison of past solar cycle activity with our most current cycles.
