Carbon CO2 emissions - 'Innocent' as charged

CO2 is essential for plant growth as it is absorbed by green plants during photosynthesis, the carbon being converted to plant mass, and the oxygen released back into the atmosphere. CO2 occurs naturally in the atmosphere at concentrations of about 0.0379% or 379 parts per million. It is neither a pollutant nor a 'greenhouse gas'.

Atmospheric carbon dioxide levels, currently only 350 parts per million have been over 18 times higher in the past at a time when cars, factories and power stations did not exist — levels rise and fall without mankind's help.

96.5% of all carbon dioxide emissions are from natural sources, mankind is responsible for only 3.5%, with 0.6% coming from fuel to move vehicles, and about 1% from fuel to heat buildings. Yet vehicle fuel (petrol) is taxed at 300% in the UK while fuel to heat buildings is taxed at 5% even though buildings emit nearly twice as much carbon dioxide! As carbon dioxide emissions from cars and factories does not have any measurable impact on climate, these taxes are 'just another tax' on enterprise and mobility, and have no green credentials whatsoever.

Atmospheric CO2 concentration profiles from Vostok ice core samples covering 420,000 years, concluding that during glaciation "the CO2 decrease lags the temperature decrease by several thousand years" and "the same sequence of climate forcing operated during each termination."
Using sections of ice core records from the last three inter-glacial transitions decided that "the time lag of the rise in CO2 concentrations with respect to temperature change is on the order of 400 to 1000 years during all three glacial-interglacial transitions."

Further On the basis of atmospheric carbon dioxide data obtained from Antarctic Taylor Dome ice core samples, and temperature data obtained from the Vostok ice core looked at the relationship between these two variables over the period 60,000-20,000 years BP (Before Present). A statistical test on the data showed that movement in the air's CO2 content lagged behind shifts in air temperature by approximately 900 years, while a second statistical test yielded a mean lag-time of 1200 years.

Similarly, in a study of air temperature and CO2 data obtained from high time resolution samples at the Antarctic Concordia Dome site, for the period 22,000-9,000 BP, which covers the last glacial-to-interglacial transition that the start of the CO2 increase lagged the start of the temperature increase by 800 years. In yet another study of the 420,000-year Vostok ice-cores concluded that variations in atmospheric CO2 concentration lagged behind variations in air temperature by 1,300 to 5,000 years. Proving once again that the greens have put effect before cause.

In other words, an increase in carbon dioxide levels, the much hyped 'cause' of global warming, actually happens long after the warming has started, demonstrating clearly that CO2 cannot possibly be the cause of global warming.

The planet does not need saving, but taking this on anyway, removing every car from every road in every country overnight would NOT produce any change in the carbon dioxide level of the atmosphere. It is pointless trying to alter climate by changing carbon dioxide levels as the cause and effect is the other way round — it is changes in the activity of the Sun that cause temperature changes on earth, with any temperature rise causing carbon dioxide to de-gas from the oceans. CO2 is not-guilty as charged. Finally the truth is here.. CO2 is completely innocent!
