Since when has CO2 been a pollutant? We breath it out and trees take it in. All focus groups, Green Peace etc, distort the reality to fit their own beliefs. The test should be purely on miles per gallon. Twice the miles per gallon half all pollutants, as per a recent letter in the Telegraph by Lord Bamford. But of course we have the climate change religion to contend with - faith not verified by fact.
Oh, dear.
Rainbowj, no offence intended to you personally, but that is one of the more ridiculous posts I have ever seen.
Carbon dioxide is known, and has been known for many years, to be a "greenhouse gas" - meaning that at even relatively low concentrations in the atmosphere it acts like a blanket, leading to an imbalance in the flow of heat from the sun to the earth. At equilibrium, the amount of heat radiated away from the earth into space is roughly the same as the amount of heat taken in by the earth from the sun. The mechanisms of the greenhouse effect are very well understood, and not really disputed. Not even the most rabid climate-change-denier is seriously questioning the ice-core and atmospheric analysis indicating a rapid increase in the level of atmospheric carbon dioxide. The attached graph (this one is from a global warming website, the data points are from multiple international organizations including NOAA in the US, the BAS from the UK, and many academic research projects) shows the startling rise, and increased rate of change, in CO2 levels since around 1750.
I would turn your assertion on its head. Not to understand the phenomenon of climate change, and to deny the likelihood of human causation of that change, is very much a triumph of faith over fact, and is not supportable by any evidence whatsoever.
Apologies for the rant, but I find people's unwillingness to acknowledge the weight of evidence of climate change really quite disturbing..
