Will the sun put the brakes on global warming?

THE sun is heading for a rare, super-chill period and we’re “not quite sure what the consequences of this will be,” scientists say.

THE sun is like a teenager that cycles through mood swings — from dramatic to chill and back again — roughly every eleven years. But this time it’s different. It now appears the sun is heading for a rare, super-chill period that threatens to add some unexpected drama to today’s climate change discussion.

For most of its history, science believed the sun’s output was constant. It was wrong. Today, we realise that lots of things about the sun wax and wane every eleven years, most notably its brightness and the number of explosive disturbances on its surface called sunspots and faculae.

That’s not all. The eleven-year cycle itself snakes up and down like a roller coaster, reaching “grand maxima” and “grand minima” every 100-200 years. The last grand maximum peaked circa 1958, after which the sun has been steadily quieting down. Today, the drop in activity is at its steepest in 9,300 years.

Is the sun headed for a grand minimum? If so, it immediately calls to mind the famous Maunder Minimum, during which the sun languished for seventy years. From 1645 to 1715 the sun’s brightness dimmed by a fraction of one per cent and the number of sunspots and faculae plummeted to nearly zero.

TIME IS THE HUNTER: Time is the hunter, we are its prey, As we pass each hour of every day, We are not aware until it's too late, What we take for granted will seal our fate.

Time gives no favour, hears no cry, Of the honest truth or the blatant lie, For in the end, what games we play, Time will have the final say.

What time we have is ours to keep, A gift on loan, while awake or sleep, To spend as we wish, our distance run, When our time is up, Our time has come.   ~CN Andre Day 1997~
