1. All energy on earth comes (or came) from the Sun, in the form of electromagnetic radiation of various spectra.
2. The source of this radiation varies cyclically due to numerous factors such as the variation in the speed of rotation of the sun’s core versus its surface; tidal effects of the planetary gravitational forces
on the sun’s surface; coupled with the Sun’s axial rotation; the ‘boiling’ phenomenon of the body of the Sun itself, manifesting as flow from the core to the surface and back again; sunspots(themselves cyclically linked to the period of the orbit of Jupiter) ; etc.
3. Electromagnetic radiation emitted by the Sun travels through space to the earth in waves of varying length, and type and intensity.
4. Thus, there is variability in the amount and type of energy reaching the earth. Some of these cycles are very long, from just a few years up to hundreds and thousands of years.
5. The effects of these changes in solar radiation striking the earth (which includes its atmosphere) are different at different times due to the changing state of the earth itself, which itself varies cyclically in a lagged response to the varying energy reaching it from the sun, which has set up a non-harmonic resonance between the earth’s cycles and the sun’s. In other words there is a non-linear relationship between the solar radiation reaching the earth and its effects.
6. The earth’s magnetic field is powered by this electromagnetic energy.
7. When Solar activity is low, the earth’s magnetic field is weaker.
8. Because the earth’s magnetic field is weaker, more cosmic rays, i.e. rays emanating from deep space – exploding stars etc., enter our atmosphere.
9. These cosmic rays passing through our atmosphere impact the water droplets in the atmosphere, causing the formation of aerosols.
10. Aerosols are necessary for cloud formation, since the water vapour cannot condense on its own unless it has something onto which it can condense. These aerosols are what it condenses onto.
11. More aerosols equals more clouds. So cloud formation is directly correlated to the Sun’s activity. Weak activity equates to more cloud formation, higher levels of solar activity equates to fewer clouds.
12. Clouds formed in this way reflect energy back out into space, thereby causing the climate to cool.
13. When the Sun’s activity is stronger, the electromagnetic field of the earth is stronger, and this acts as a shield for the atmosphere, causing more cosmic rays to be bounced back into space and so there is less cloud formation and the atmosphere heats up.
14. Any a priori presumption of stability of the earth’s temperature is ludicrous, borne out by historical evidence of ice ages and warm periods. One trivial example is the Roman vineyard near Leeds. And the reason Greenland was called Greenland by the Vikings who sailed there..(clue: because it was green, not covered in ice, as now). These changes obviously occurred independently of any man made impact on the make-up of the earth’s atmosphere.
15. What is the total amount of CO2 as a percentage of the earth’s atmosphere ?? (Answer : 0.039%).
16. H2O is 0.25% of the earth’s atmosphere.
17. If the earth is a receptor for energy flow, and that flow varies quite considerably over long and short periods, consider whether this is the more likely cause of variability in earth’s climate or whether the relatively recent phenomenon of possibly increasing CO2 is responsible.
18. We’re actually heading for a new Ice Age. Maybe you’ve noticed it’s been a bit cooler lately.
Here’s a brilliant movie produced by Henrik Svensmark, the originator of the Cloud Effect Theory. Here
OK.. I would like to add that I’m not a rabid arguer in favour of the above (I try to steer clear of rabid anything!). I’ve never really been one for trying to convert people to my view at all costs, since I recognize all humans are fallible. I pretty much try to observe the situation and diplomatically say what I feel and explain the reasons why and then agree to disagree if people don’t see it my way.
Thus, I’m not a climate change skeptic.
The climate changes as it always has and will continue to do so. I am just very fairly certain that CO2 is not the CAUSE.
In reference to my point 7 above, here’s a Wikipedia link.
https://en.wikipedia.org/wiki/Carbon_dioxide. To save you the click, here’s the important bit.
Carbon dioxide (chemical formula CO2) is a naturally occurring chemical compound composed of two oxygen atoms covalently bonded to a single carbon atom. It is a gas at standard temperature and pressure and exists in Earth’s atmosphere in this state, as a trace gas at a concentration of 0.039 per cent by volume.
0.039% of the atmosphere versus massive variability in the flow of the source of all energy powering this planet. Hmmmmm….
Furthermore, regardless of what you or I think, China is building 50 new coal fired power stations, so the amount of this trace gas being generated by humans and pumped into the atmosphere is going to rise not fall. We’re just passengers.
I would also add that from a risk perspective, the more negative outcome for humanity is an ice age not a warm period. Vineyards in Yorkshire vs. low yields in wheat crops, poor harvests and high food prices, mass human starvation etc etc.
We can’t influence the climate. The eventual resolution is baked in. I think it’s another example of mankind having a huge ego trip akin to believing that the Sun orbits the Earth and not vice versa.
Everything is cyclical. Here’s a solar cycle chart showing temperature correlated to solar activity and extrapolated forward. http://acutedisorder.com/?p=161
That’s why I think it’s going to get colder over the next 15 to 20 years, not the other way round.
Of course I could be wrong. What a fool.
