We shouldn't be trying to eliminate carbon emissions, we should be grateful for them! Can we use science instead of hype?
The amount of carbon in the atmosphere is measured in PPM, which means parts per million. What if we had 500 PPM in the atmosphere today? That is only a tiny trace of the composition of the atmosphere and completely unable to cause large changes in temperature. It is like saying your car won't move because an insect is blocking a front tire!

This report was a piece of blatant, politically motivated bad science and pure propaganda…
an international embarrassment of American scientific expertise and is so full of misleading data, false assumptions, and invalid conclusions that it simply cannot be relied upon as a policy making reference.The report cites 569 references, but how many readers are going to go to the trouble of looking any of them up to discover that they don’t support the position of the text, or have been so selectively quoted that they are relied on to say the opposite to what was meant?
The most widely used herbicide in the United States, glyphosate (RoundUp®), loses its efficacy on weeds grown at carbon dioxide levels that are projected to occur in the coming decades (see photos below).
Higher concentrations of the chemical and more frequent spraying thus will be needed, increasing economic and environmental costs associated with chemical use.
For the United States and many developed countries, chemical methodologies allow for cheap, effective weed control. Actually, a single herbicide, glyphosate (commercially sold as “Round-Up”), is so effective in controlling weeds that more than three-quarters of the U.S. soybean crop, and over a third of the U.S. corn crop have been genetically modified to be glyphosate resistant (e.g., Gaskell et al. 1999).
Unfortunately, there are also an increasing number of studies (Ziska et al. 1999, 2004; Ziska and Teasdale 2000; Ziska and Goins 2006a) that demonstrate a decline in chemical efficacy with rising CO2 per se. Given the evidence from field and laboratory trials, it appears that declining efficacy of herbicides with increasing CO2 is very likely to affect the environmental and economic cost of pesticide usage (Ziska et al. 1999; Ziska and Teasdale 2000).
Higher concentrations of the chemical and more frequent spraying thus will be needed, increasing economic and environmental costs associated with chemical use [emphasis mine].
The most damaging aspect of science today is widely promulgated theories that are contradicted by observation and experiment. In both cases, a story is mandated by authority and then defended by educational, economic, and sociopolitical agencies.
