Eliminating all Man-Made CO2 -- Earth gets Warmer?
- Jun 8, 2015 10:27 pm GMT
Do you realize that CO2 emissions created by man's activities, combustion of fuels, etc. (called anthropogenic emissions) is miniscule compared to the emissions of CO2 from nature? Table 1 was developed by the IPCC. It shows annual CO2 emissions to the atmosphere from both nature and man and how much of the CO2 emitted is re-absorbed by nature.
Using the table above in combination with a total concentration of 385 ppmv of CO2 seen in the atmosphere in January 2008, one sees that the increase in CO2 caused by all of man's activities amounted to only 11.5 ppmv. The amount of CO2 from man is a mouse milk quantity compared to nature's emissions. If we eliminated all anthropogenic CO2 emissions, we would go back to the level we had in January 2003. Oh yes, when it was warmer then than it is now. Isn't this the first thing one would look at when evaluating the effect of man-made CO2; that is if they had any common sense? It is clear that CO2 concentration in the atmosphere has nothing to do with the earth temperature. If there is an effect it is so small it is not worthy of discussion.
Global warming advocates say that CO2 builds up in the atmosphere over a 50 to 250 year period, but this is not true. Figure 1 below shows that the CO2 concentration oscillates based on the growing season in the Northern Hemisphere. The ratio of land to ocean in the Northern Hemisphere is about 1 to 1.5 and in the Southern Hemisphere is 1 to 4. Therefore, the Northern Hemisphere with much more land mass has a growing season that dominates the Southern Hemisphere growing season with respect to absorption of CO2.
Does a correlation exist between the concentration of CO2 in the atmosphere and the earth's temperature? No! Does an increase in CO2 cause the earth's temperature to increase? No! Figure 1 below was developed by Joseph D'Aleo, certified meteorologist. Even a non-scientist can see there is absolutely no correlation between CO2 concentration in the atmosphere and the earth's temperature. If there were a correlation, they both would rise and fall together. The CO2 has been on a continuous upward trend - not true for the earth's temperature.
In Figure 1, each year around April, increased CO2 absorption by plants in the Northern Hemisphere starts reducing the CO2 in the atmosphere and the reduction continues until around mid to late August when plants start to go dormant. The cycles occur on a regular yearly basis and the swing in CO2 concentration is in the 5 to 8 ppmv range. If CO2 stayed in the atmosphere for long periods before being consumed, the season to season cyclic effect would not be seen. It is clear that nature reacts very fast in its consumption of carbon dioxide.
The atmospheric concentrations of CO2 were taken at the Mauna Loa Observatory in Hawaii. Two sets of temperature measurements are shown, one set by NASA's Microwave Sounding Unit (MSU) for the troposphere and the other by the UK's Hadley Climate Research Unit for the land and sea. Both show declining temperatures over time even as CO2 has increased from 366 ppmv in January 1998 to 385 ppmv by January 2008. Note that the land-sea and lower troposphere temperatures in January 2008 were some 0.7 Degrees C cooler than in January 1998.
