'Mini ice age' predicted within 15 years

Scientists have calculated that much of the planet could soon be plunged in to a decade-long cold spell.
The northern hemisphere could soon find itself being plummeted in to a period of bitter winters - that is according to researchers at the University of Northumbria who have developed a new solar activity model capable of predicting temperature changes with 'unprecedented accuracy'.

The last time this happened was over three centuries ago and caused winters so cold that the River Thames famously froze over for weeks at a time and frost fairs were held on the ice.

These miniature ice ages are brought about by fluid movements in the sun and occur when two prominent waves cancel each other out leading to what is known as a "Maunder minimum."

"We found magnetic wave components appearing in pairs, originating in two different layers in the sunís interior," said Prof Valentina Zharkova. "They both have a frequency of approximately 11 years, although this frequency is slightly different, and they are offset in time."

"Over the cycle, the waves fluctuate between the northern and southern hemispheres of the Sun. Combining both waves together and comparing to real data for the current solar cycle, we found that our predictions showed an accuracy of 97 per cent."

Here in Blighty no one seems to give a yawn about pollution any more. My thoughts are: Assuming it's right about pollution, who is going to be clever enough politically to turn the trend around in any of the developed countries? Or indeed in those countries wishing to emulate the status quo. Most of us earn our living by polluting in one way or another. It would appear that pollution is a necessary by product of progress. I guess we will all have to become Amish and mish out on all the modern toys.

P.S.: To get global temps down to LIA levels is going to require some volcanos as well as a weaker sun. Not saying it can't happen, but it isn't real likely. Doug It could happen. I searched "solar activity and volcanoes," and came up with a bunch of hits. It seems that many scientists do believe that there is a relationship between a solar minimum and earthquakes and volcanic activity. I shall do more reading about this tomorrow. "Can Solar Activity Cause Earthquakes, Volcanoes and Extreme Weather?" http://georgewashington2.blogspot.com/2011/08/does-solar-activity-influence.html

I don't remember whether I saw it in "Science" or "Science News" but there was a recent headline that said "The Little Ice Age was global." I didn't read it, but I'll look and see if I still have it. I better restate that: the Little Ice Age was global, but it had different effects in different places - more pronounced in Europe, less pronounced in the US and Southern Hemisphere. Doug

Thanks, Doug. That's an excellent post. I think you covered about everything. The fact that pollution continues bothers me most. Things like dioxin, benzene, mercury, etc.... all the petrochemical poisons. It seems to me when politicians go after the CO2 they're ignoring the real toxins. I remember when plants would belch out black smoke. Those carbon particles are heavy. They eventually fall back to the earth. In my opinion, the carbon is not a problem. It just goes back to dirt. The CO2 feeds the vegetation. Can't they filter out the poisons and leave the innocuous elements and gases alone? ... [More]

Natural forests can act as carbon sinks, but swamps do a better job. Florida's Everglades, Big Cypress Swamp and the other one with the name I can't pronounce are examples. There are also major swamps in Louisiana and along the Mississippi. Houston, Texas is a swamp they tried to fill in - didn't work real well - the swamp is still there. Anyway, all these areas act as carbon sinks and can help somewhat with mitigation, but the only reaql solution is to quit making so much CO2.Doug Every one of those carbon sinks will become an emitter if the global average temperature reaches certain levels. ...

CO2 in excess quantities is also harmful to life. Of course that's true, and I'm not trying to be argumentative when I suggest that I feel that CO2 has been unnecessarily demonized. Certainly, pollution is toxic and poison and will lead to a miserable death. And ... those poisons are held down by greenhouse gases in many parts of the world. I can remember days in Los Angeles when the air made my eyes burn. Changes in public transportation and uber stiff laws for cars and industries that contribute to the pollution would help a lot... as well as less sprawl in houses and more luxury "stack and ...

A bit of hyperbole... but I understand what you're saying. My source on that was James Hanson's book on global warming. He lays out the numbers. I think it safe to say that none of us would survive long enough to actually see that happen. For decades I have read or watched the liberal news and then the conservative news... daily. That's the only way to get a true picture of what is happening in politics and (unfortunately ...) climate science. When one examines a subject from both points of view, one begins to see the agendas on both sides. There is good science on both sides of the debate.. j... [More]

We use hydroelectric now, but that's mostly coal generated with a few nuclear plants here and there. Duh! I was mistaken. We use hydroelectric power around here, but it's NOT coal generated. So we're clean.

Carbon dioxide is lethal at a concentration of 11%. That doesn't leave much room for error. http://avogadro.chem...bon_dioxide.pdf Doug Oh wow! That's a blast from the past. When I first began working on the ambulance, we had to carry the MSDS book on the ambulance. That thing must have weighed 30 pounds!. And we had to replace with new sheets every week. It was a happy day in the early 90's when we began to carry laptops and could just look up the hazardous material. That MSDS sheet is for how to handle a bottle of compressed CO2. CO2 is an asphyxiant gas, but it's not toxic. In an enclosed s... [More]

What I'm saying is that CO2 is not a toxin, nor is it lethal unless you're in an enclosed space for long enough to displace most of the O2. That is suffocation. The fact remains that CO2 traps heat in the atmosphere. That is detrimental to living things. And that makes it a pollutant. Context is crucial. Ozone is beneficial when high in the atmosphere where it protects us from ultraviolet light. But at ground level, it is toxic to vegetation, causing chemical burns on leaves. Same thing applies to CO2. In an animal, it is a waste product that will cause serious harm if levels get too high. In ... [More]
