BAD NEWS FOR WARMISTS:
SUN HAS 'WEAKEST SOLAR CYCLE IN A CENTURY'
Thomas Lifson – Feb. 18, 2015 - www.americanthinker.com
There have been two notable historical periods with decades-long episodes of low solar activity. The first period is known as the “Maunder Minimum”, named after the solar astronomer Edward Maunder, and it lasted from around 1645 to 1715. The second one is referred to as the “Dalton Minimum”, named for the English meteorologist John Dalton, and it lasted from about 1790 to 1830. Both of these historical periods coincided with below-normal global temperatures in an era now referred to by many as the “Little Ice Age”.
The conceit that human production of carbon dioxide is capable of driving the earth’s climate is running smack into the sun. CO2 accounts for a mere 0.039% of the atmosphere, while the sun accounts for 99.86% of all of the mass in our entire solar system. And Ol’ Sol is not taking the insult lightly. Vencore Weather reports:
For the past five days, solar activity has been very low and one measure of solar activity – its x-ray output – has basically flat-lined in recent days (plot below courtesy NOAA/Space Weather Prediction Center). Not since Cycle 14 peaked in February 1906 has there been a solar cycle with fewer sunspots.
We are currently more than six years into Solar Cycle 24 and today the sun is virtually spotless despite the fact that we are still in what is considered to be its solar maximum phase. Solar cycle 24 began after an unusually deep solar minimum that lasted from 2007 to 2009 which included more spotless days on the sun compared to any minimum in almost a century.
There are several possible consequences to the solar quiet. The first is counterintuitive:
By all Earth-based measures of geomagnetic and geo-effective solar activity, this cycle has been extremely quiet. However, while a weak solar cycle does suggest strong solar storms will occur less often than during stronger and more active cycles, it does not rule them out entirely. In fact, the famous Carrington Event of 1859 occurred during a weak solar cycle (#10) [http://thesiweather.com/2014/09/02/300-pm-the-carrington-event-of-1859-a-solar-superstorm-that-took-places-155-years-ago/]. In addition, there is some evidence that most large events such as strong solar flares and significant geomagnetic storms tend to occur in the declining phase of the solar cycle. In other words, there is still a chance for significant solar activity in the months and years ahead.
Our dependence on electronic devices is such that extreme solar events could have serious consequences. However, it is the likely impact on atmospheric temperatures that threatens the “consensus” on global warming:
…if history is a guide, it is safe to say that weak solar activity for a prolonged period of time can have a negative impact on global temperatures in the troposphere which is the bottom-most layer of Earth’s atmosphere - and where we all live. There have been two notable historical periods with decades-long episodes of low solar activity. The first period is known as the “Maunder Minimum”, named after the solar astronomer Edward Maunder, and it lasted from around 1645 to 1715. The second one is referred to as the “Dalton Minimum”, named for the English meteorologist John Dalton, and it lasted from about 1790 to 1830. Both of these historical periods coincided with below-normal global temperatures in an era now referred to by many as the “Little Ice Age”. In addition, research studies in just the past couple of decades have found a complicated relationship between solar activity, cosmic rays, and clouds on Earth. This research suggests that in times of low solar activity where solar winds are typically weak; more cosmic rays reach the Earth’s atmosphere which, in turn, has been found to lead to an increase in certain types of clouds that can act to cool the Earth.
It is common sense to believe that the sun has more influence on global temperatures than a trace gas. With a seventeen-year “pause” in the predicted outcomes of an increase in atmospheric CO2, warmists face more and more awkward questions. If temperatures actually decline as a result of an expected decrease in solar activity, at some point the game will be up, and the billions of dollars a year squandered on climate modeling that doesn’t predict what happens will have to dry up.
