Carbon dioxide, the friendly gas
The sun, water and CO2 are essential for photosynthesis and for
life on this planet. 1,500 ppm allows photosynthesis at an optimum rate. At 180 ppm, plants stop growing. At 150 ppm - plants are dead! To enhance plant growth, many greenhouses add 800-1,000 ppm. Plants grow best at a CO2 concentration of 1,500 ppm, which
boosts plant yield by 40 to 60 percent.
The current level of CO2 is about 415 ppm or 0.04% of the atmosphere. The historic atmospheric low level of CO2 was thought to be 273 ppm in about 1750 AD. Levels in 1910 were 280 and in 1945 were 298 ppm. Dr Patrick Moore, environmental consultant (Simon Fraser University) believes these levels to be dangerously low. It is a fact that CO2 levels were much higher than they are today during previous eras (when plant life was evolving).
Average earth surface temperatures have fluctuated during the past 100 years, sometimes cooling, sometimes warming, and in balance has increased somewhat, especially during the periods from 1910 to 1940 and from 1980 to 1998. Since 1998 there has been no further warming and since 2016 a slight cooling is underway. Record warm temperatures occurred during the 1930 to early 1940’s period (when CO2 levels were lower than at present). This suggests that ‘CO2 is not the control knob’ and that the sun and water vapour are bigger factors.
Humans can easily tolerate 5,000 to 10,000 ppm. We breathe in 0.04% and we breathe out 4% CO2. When many of us are confined in small spaces for a significant amount of time, CO2 level in the space rises. Some examples: - passenger airline cabin: 680 ppm - conference room in office building: 800 to 1,200 ppm - the International Space Station: 5,250 ppm maximum daily average. CO2 is non-toxic and safe to consume. For example, it is used extensively to carbonate beverages.
Each human on earth (now about 7.7 billion persons) breathes out about 370 lb (168 kg) of CO2 each year. Such non-toxic emissions are beneficial - greening the earth and definitely increasing the yield of food crops. A very necessary gas, CO2 is not a pollutant.

MY VIEWPOINT: These knowledgeable and sensible
views by professional scientists are actively suppressed by the IPCC and many governments, not because they lack credibility, but because they counter the active socialist agenda of United Nations agencies.
I have followed Dr. Patrick Moore and Dr. Tim Ball for many years and find their observations credible and rational.
It is thirty-four years since the IPCC was created in 1988. Thousands of barrels of ink have gone into reports predicting sharp increases in global temperatures and devastation of humanity have failed to materialize. There is nothing rational or sound about IPCC “science.”
Science is the art of investigating everything we think we know to disprove those theories that cannot be replicated in controlled conditions and enhancing our knowledge base by discovering factors not previously considered. Science does not care what we believe.
Three decades of unscientific propaganda bolstered by the biennial gathering of thousands of worldwide climate change delegates has created a closed cult of believers that rivals traditional religions. Costs to member nations are enormous, as are the unnecessary efforts to reduce carbon emissions.
The underlying motive of the IPCC is to penalize industrialized nations for their formidable success. That is why emerging countries get a free pass on emission reductions. That is why industrialized nations are called polluters while other nations that contribute to carbon emissions are not. The IPCC engages in blatant discrimination and has expressed frustrations at being thwarted from transferring $ billions in penalties to the third world.
One only has to examine the truth that the control of money equals power to understand the motives of the IPCC. It is also true that while control of money equals power, power corrupts.
Governments want to censor our speech. Without the freedom of expression, we cannot pick out the idiots.
