Sunspot activity
Sunspot activity is a cycle that cycles about every 11 years. Sunspots are indicative of increased cosmic radiation and since 2000 (the last peak) has been steadily declining. It is now at the low point in the cycle, and from now, for the next 11 years it will increase.

This is normal, nothing to get excited about, except that sunspot activity increases may affect both climate change and it is also possible that with the world now far more reliable on microwave communications, cell phones, etc. that we will experience increasing interference. Since the cell phone revolution’s real growth has occurred in the past 10 years, if cosmic radiation becomes a factor, it could spell times when communications are disrupted. Business reliance on text messaging and other infrastructure issues are not going to cause a disaster, but may be more expensive to tax payers ultimately.

…the rest of the story. Climate is changing and always will. The climate celebrities, however, are linking climate and the economy. Yes, there has been warming to end the Pleistocene. Climate is a multiple input, multiple loop, multiple output, complex system. The facts and the hypotheses, however, do not support CO2 as a serious ‘pollutant’. In fact, it is plant fertilizer and seriously important to all life on the planet. It is the red herring used to unwind our economy. That issue makes the science relevant.
Sulphate from volcanoes can have a catastrophic effect, but water vapour is far more important. Water vapour (0.4% overall by volume in air, but 1 – 4 % near the surface) is the most effective green house blanket followed by methane (0.0001745%). The third ranking gas is CO2 (0.0383%), and it does not correlate well with global warming or cooling either; in fact, CO2 in the atmosphere trails warming which is clear natural evidence for its well-studied inverse solubility in water: CO2 dissolves rapidly in cold water and bubbles rapidly out of warm water. The equilibrium in seawater is very high; making seawater a great ‘sink’; CO2 is 34 times more soluble in water than air is soluble in water.
CO2 has been rising and Earth and her oceans have been warming. However, the correlation trails. Correlation, moreover, is not causation. The causation is under scientific review, however, and while the radiation from the sun varies only in the fourth decimal place, the magnetism is awesome.
“Using a box of air in a Copenhagen lab, physicists traced the growth of clusters of molecules of the kind that build cloud condensation nuclei. These are specks of sulphuric acid on which cloud droplets form. High-energy particles driven through the laboratory ceiling by exploded stars far away in the Galaxy – the cosmic rays – liberate electrons in the air, which help the molecular clusters to form much faster than climate scientists have modeled in the atmosphere. That may explain the link between cosmic rays, cloudiness and climate change.”
As I understand it, the hypothesis of the Danish National Space Center goes as follows:
Quiet sun allows the geomagnetic shield to drop. Incoming galactic cosmic ray flux creates more low-level clouds, more snow, and more albedo effect as more is heat reflected resulting in a colder climate.
Active sun has an enhanced magnetic field which induces Earth’s geomagnetic shield response. Earth has fewer low-level clouds, less rain, snow and ice, and less albedo (less heat reflected) producing a warmer climate.
That is how the bulk of climate change works, coupled with (modulated by) sunspot peak frequency there are cycles of global warming and cooling like waves in the ocean. When the waves are closely spaced, all the planets warm; when the waves are spaced farther apart, all the planets cool.
The change on cloud cover is only a small percentage, and the ultimate cause of the solar magnetic cycle may be cyclicity in the Sun-Jupiter centre of gravity. We await more on that.
Although the post 60s warming period appears to be over, it has allowed the principal green house gas, water vapour, to kick in with more humidity, clouds, rain and snow depending on where you live to provide the negative feedback that scientists use to explain the existence of complex life on Earth for 550 million years. Ancient sedimentary rocks and paleontological evidence indicate the planet has had abundant liquid water over the entire span. The planet heats and cools naturally and our gasses are the thermostat. Nothing unusual going on except for the Orwellian politics.

Interesting. You can see obvious evidence of climate change, even during my relatively short life NZ’s glaciers have receded and the ice in Greenland has started to melt.
The crime of humanity is not political, it is the rape of natural resources which is putting pollution into the air and into the sea.
Orwellian politics? Sounds like hot air to me. What evidence of Orwellian political motivations being tied into climate change are there exactly?
Seems to me more likely its sectional interests who need to pollute for free to turn a profit are taking something that is not theirs. More than their fair share.
