Sunspotless Day tally now puts 2009 in 5th place, closing in on 2008

Via ICECAP, Dec 09, 2009

Today marked the 17th straight day without a sunspot. It will according to spaceweather will mark the 260th sunspotless day this year and the 771st spotless day this minimum.  This moves 2009 into 5th place in the top 20 spotless years since 1849, when that kind of assessment became reasonable. See the enlarged image here.

See how the sunspot number has not recovered from the expect minimum (declared by NASA first in December 2008!!!). See the enlarged image here.

This long cycle and the last 3 suggest that the phasing of the 213 year and 106 low solar cycle may be at work as it was in the late 1700s and the early 1800s, the so-called Dalton Minimum (below, enlarged here), the age of Dickens. Those days, snow was common in London. Ironically last winter was one of the snowiest in London in many a decade. Snow will fall next week in England (and Copenhagen). More later.

IS CARBON DI OXIDE THE VILLAIN?

Such terms as carbon credit find a place in newspapers almost daily. I don’t know what is all this about. To me CO2 sustains life on earth. Has the level of CO2 in the atmosphere gone up? Has it been proved experimentally?
Before Industrialization
The whole of America and most of the old world were inhabited by a comparatively small population, a majority of whom depended upon meat and fish. Farming depended entirely on rain water as big dams were unknown. The grasslands of America and Australia didn’t produce food grains. Coal and other fossil fuels were not commercially exploited. In those days we may presume that a proper balance existed between CO2 and other ingredients of the air like N2 and O2 in spite of forest fires, the like of which we witnessed in California recently.

After Industrialization
Commercial exploitation of coal began first followed by oil and natural gas, resulting in increase in the level of CO2 in the atmosphere. Simultaneously two other developments followed: increase in population (both human and animal) and corresponding growth in food grains production. Big dams were constructed and more and more areas of land were brought under cultivation. Mechanization and the use of artificial fertilizers made leaps and bounds in production of food grains, fruits and other commercial crops. The Prairies of North America became the granary of the world. Compared to grass, food grains and sugar fix a large quantity of CO2. The major items responsible for such CO2 fixation are:

food grains like wheat, corn, rice, oats, soybean etc
underground vegetables like potato, tapioca, beetroot etc
fruits like apple, grapes, banana, dates, cherry, pineapple etc
sugarcane etc

Experts can calculate the total quantity of CO2 produced by industry and that absorbed by vegetation as mentioned above and the marine vegetation in order to find out whether the net balance is favoring CO2 concentration in the air. An easier way would be to experimentally ascertain the percentage of CO2 in the atmospheric air (being heavier than air CO2 is available near the surface of the earth). If CO2 level increases O2 level should decrease. In my childhood (I am 70+) O2 level was 20% as mentioned in my text book. Has it changed? An atom of carbon combines with two atoms of oxygen to form CO2 which is absorbed by the leaves of the plant to form starch. In the process two atoms of oxygen are released into the atmosphere. We may say that each carbon atom burnt ultimately results in the release of two atoms of oxygen, thus resulting in increase in the level of O2. Level of CO2 dissolved in the ocean water should also be checked. If this level increases, fishes would die en mass. Has this happened? If the level of CO2 dissolved in ocean waters decreases, plant life in the ocean cannot produce enough starch by photosynthesis. This will be a hazard for fishes and other marine life.

The volume of animal and hence plant life in the oceans is much more than that on the continents. This is because the area of the oceans is seven times the area of the continents. Also, the oceans are deep. Hence the volume of water is very much more and can contain a large population of marine life. The necessary starch has to come from plant life. So, the total bio mass in the oceans is considerably higher than that in the continent. The carbon di oxideàPlant starchàAnimalsàCarbon di oxide cycle is there in the watery medium, just as in our atmosphere. All the gases, including nitrogen, will be present in dissolved state in the oceans too. Here industrialization has not affected the ‘atmosphere’ of the ocean. This fact has to be recognized in any discussion on Global Warming.

[The percentage of various components of atmospheric air as obtained from the websites is given below:

Nitrogen 78.1
Oxygen 20.9
Argon 0.9
Neon 0.002
Helium 0.0005
Krypton 0.0001
Hydrogen 0.00005
Carbon di oxide 0.035!!!!!!!! (Poor, innocent CO2 has been maligned unnecessarily)
Methane 0.0002
Ozone 0.000004

This would suggest that the percentage of oxygen has slightly increased. If this is true it augers ill, as forest fires may become uncontrollable with increase in the level of oxygen in the coming years. Therefore, this line should be investigated separately by experts. My guess is that with unchecked use of nitrogenous fertilizers, the total bio mass in the earth could have increased. The requisite extra nitrogen must have been drawn from the atmosphere along with CO2 releasing extra oxygen into the atmosphere as pointed out above.]

The importance of proper scientific study cannot be over emphasized. Mother Nature maintains her balance, whatever her children may do!

Please fix the image of comparison of Maunder Minimum and present conditions. It doesn’t get any bigger when you click it and I’d really like to be able to look at it.

Tks!
