Man-made global warming is junk science. So say highly-qualified experts from the ‘hard’ sciences. Poorly trained government climate ‘experts’ for too long refused to share their half-baked theories and data about the role of atmospheric carbon dioxide (CO2) with better qualified experts. 
Below are typical well-known and established scientific facts that climate change alarmists would rather keep from you.
- As part of the “Carbon Cycle”, through photosynthesis, atmospheric carbon dioxide is the sole source of the oxygen that we need to breathe (one molecule of CO2 produces one molecule of O2).
- Similarly, through photosynthesis,our entire food supply (animal and vegetable) is dependent upon carbon dioxide. Needless to say, carbon dioxide is essential to our survival.
- In Calgary, Alberta, we accommodate “seasonal” temperature changes from, say, +30 C (summer) to -30 C (winter) for a 60 C temperature range, which is due to the Sun. The +2 C “drift” in “average” global temperatures is attributed, by alarmists, to carbon dioxide (currently 400 ppm, parts-per-million, by volume in the atmosphere).
- Carbon dioxide is a much poorer “green house gas” than water vapour (by a factor of ~160, see thermodynamic analysis: http://www.biocab.org/Heat Stored.html). Water vapour (at 1{154653b9ea5f83bbbf00f55de12e21cba2da5b4b158a426ee0e27ae0c1b44117} or 10,000 ppm, by volume in the atmosphere) is particularly prevalent over the oceans that cover three-quarters of the surface of our planet.
- A recent publication by NASA suggests that carbon dioxide actually contributes to “Global Cooling”:http://www.naturalnews.com/040448 solar radiation global warming debunked.html
- There are fossils of palm trees in the high Arctic and evidence of a previous Ice Age that had little to do with the activities of Man.
- Meaningful, unbiased/objective, “hard” sources of global data regarding sources of carbon dioxide can be difficult to find in a format suitable for comparison purposes.
- The site http://www.planetseed.com/relatedarticle/carbon-dioxide-sources provides an excellent list of sources, but ignores the contribution of “natural” forest and grass fires.
