The Canadian Space Agency’s radio telescope has been reporting Flux Density Values so low they will mean a mini ice age if they continue.
Like the number of sunspots, the Flux Density Values reflect the Sun’s magnetic activity, which affects the rate at which the Sun radiates energy and warmth. CSA project director Ken Tapping calls the radio telescope that supplies NASA and the rest of the world with daily values of the Sun’s magnetic activity a “stethoscope on the Sun”. In this case, however, it is the “doctor” whose health is directly affected by the readings.
This is because when the magnetic activity is low, the Sun is dimmer, and puts out less radiant warmth. If the Sun goes into dim mode, as it has in the past, the Earth gets much colder.
Tapping, who was originally from Kent, says that “Typically as you go through the ten or eleven year solar activity cycle you see the numbers go up or down. The lowest number is 64 or 68. The numbers 71 or 72 are very low, but they usually start to go up. We are at the end of a cycle, but the numbers still haven’t gone up. We have been joking around coffee that we may be seeing the Sun about to shut down.” (To date Tapping has been far more concerned about global warming.)
It's clear what we have to do - increase greenhouse gas emissions! If we don't warm up the Earth, who's gonna do it? The Sun has a history of these little slowdowns:
“This period of solar inactivity also corresponds to a climatic period called the Little Ice Age when rivers that are normally ice-free froze and snow fields remained year-round at lower altitudes.” It was called the Maunder Minimum, after Edward Maunder, a British accountant who saw a sunspot “like a tack in the Sun” while he was walking home, and subsequently made counting and analyzing sunspots, rather than money, his life’s work. There have been other Minimums. The Dalton Minimum of 1800 to 1810 was that period when Napoleon had his unfortunate encounter with the Russian winter.
If the Sun’s magnetic activity does not increase, and it goes dim for an extended period, it will get quite chilly.
Instead of an economic stimulus package the government should buy all of us V-8 SUVs and let's get driving to save the Earth!
