More Reader Feedback on Climate Change: Earth Headed for a Mini Ice Age

WE CONTINUE TO RECEIVE READER FEED BACK ON CLIMATE CHANGE.

One reader referred us to an July 11, 2015 in The Telegraph article by Dan Hyde writing entitled the “Earth heading for ‘mini ice age” within 15 years and that scientists say the “River Thames could freeze over in the 2030’s when the Northern Hemisphere faces bitterly cold winters.”  (The Telegraph is a publication in the United Kingdom.)

According to Mr. Hyde: “Solar researchers at the University of Northumbria have created a new model of the sun’s activity which they claim produces “unprecedentedly accurate predictions”.

They said fluid movements within the sun, which are thought to create 11-year cycles in the weather, will converge in such a way that temperatures will fall dramatically in the 2030s.

Solar activity will fall by 60 per cent as two waves of fluid “effectively cancel each other out”, according to Prof Valentina Zharkova.”

Professor Zharkova, in her presentation at the National Astronomy Meeting in Llandudno said: The result would be similar to freezing conditions of the late 17th century.”

The effect will be that in the cycle between 2030 and 2049 “the two waves exactly mirror each other – peaking at the same time but in opposite hemispheres of the sun.”

“We predict that this will lead to the properties of a ‘Maunder minimum.” Maunder minimum, indicating low sunspot activity, was the name given to the period between 1645 and 1715, when Europe and North America experienced very cold winters.)

Additionally she said:
• “Climate change could undermine the last 50 years of health advances”
• “Loaves of bread ‘smaller in future’ due to climate change”
• “Polar bears ‘have started eating dolphins due to climate change”

In a July 13, 2015 in http://www.IFLSCIENCE.com, Caroline Reid explains the Maunder minimum:

“The Maunder minimum was a 70-year period between 1645 and 1715. The Sun produced barely any sunspots and the Earth experienced a mini ice age. Parts of northern Europe and the United States experienced uncharacteristically cold winters. The river Thames, flowing through London, even froze over for seven weeks and was passable by foot. The surface was so stable that residents could even hold ‘frost fairs’ on the ice.

Sunspots are relatively ‘cool’ regions on the Sun that appear darker when photographed. They are cooler than the rest of the Sun, but they are still around 4500 K (4200ºC, 7600ºF). They are caused by a concentration of intense, magnetic field from the Sun. This inhibits and redirects the flow of hot matter to that region and makes it darker – what we call a sunspot.

Sunspots last between 1 to 100 days, during which they rotate around the Sun, following the flow of solar fluid. Sunspots go through cycles of intensity and sparsity based on the motion of the fluid cycles. There are two main waves that are slightly offset over time, producing periods of maximum and minimum solar activity.”

THEN ALMOST CONCURRENTLY THIS READER’S REFERED TO A JULY 16, 2015 ARTICLE IN the guardian BY DANA NUCCITELLI ENTITLED “Back from the dead.”

“Recently there’s been a flood of media stories claiming that the sun may be headed towards a quiet phase (a possibility), which could send the Earth into a “deep freeze” (a virtual impossibility). These stories appear to have originated in the biased conservative media (like the Daily Mail and Telegraph) and seeped into other media outlets (like CNN). Some media outlets, like the Washington Post, did a good job researching the story and discovering its flaws before publishing.

The stories stemmed from a presentation at the Royal Astronomical Society’s National Astronomy Meeting in Wales by mathematician Valentina Zharkova. Her research (not yet published) suggests the sun could be headed for a quiet phase like the one that coincided with a period known as the “Little Ice Age,” but doesn’t say anything about how this solar minimum would impact the Earth’s climate.

Some of the fault for raising this zombie myth from the dead lies with the Royal Astronomical Society’s press release, which mentioned the previous mini ice age without making it clear that it was solar activity but not the Earth’s climate that was the subject of the study. Some of the fault lies with Zharkova, who made comments ‘skeptical’ of human-caused global warming that were not supported by her research.

And much of the fault lies with media oulets like the Daily Mail and Telegraph, which ran rather sensationalist stories about an impending mini ice age apparently without consulting a single climate scientist. It’s not a coincidence that the media outlets that didn’t contact climate scientists spread this myth, while the media outlets that did contact climate scientists debunked it.”

THEN THIS EMAIL:

“Welcome to the world of controversy.”

ONE OTHER READER OFFERED THESE COMMENTS:

“Generally, greenhouse gases are not bad:
-the most abundant (number one) greenhouse gas is: H2O (water vapor) – greater than 90%; CO2 levels vary between 3% and 5%
-all animals exhale CO2; should we kill all the spotted owls, baby seals, polar bears and other endangered species because they exhale carbon dioxide ?
-plants and animals have a symbiotic relationship with each other – neither can survive without the other
-plants produce oxygen for animals to breathe
-animals produce carbon dioxide for the plants to absorb/carry out photosynthesis and produce oxygen for the animals to breathe
-crop production is best when the carbon dioxide levels are highest; some farmers purchase land closest to coproducing electrical plants because of the increased carbon dioxide production from them resulting in higher crop yields (before the EPA enforced regulations to cut back on the emissions/shut them down).”

The reader continued: “I believe everything that I have stated can be verified through Wikipedia and other Internet sources, but you will have to do digging. It is only because I am positive that the amount of water vapor has not decreased by 90% since my ecology final in college was based on greenhouse gases, that I was able to assimilate the above bullet points. All of this BS is to promote higher taxes (redistribution of wealth). In the Bible this is referred to as the New World order. Agenda 21 is the plan for the 21st century agreed to by Bill Clinton in 1992 at the Earth Summit and agreed to by every president since then; the United Nations refers to it as one world government.”
