The award winning Bengtsson, highly decorated by scientific bodies across the globe, also pointed out that the heating effect of carbon dioxide (CO2) is logarithmic, which means the higher the concentration is, the smaller the effect of a further increase.

The company said it knows anecdotally that chewing gum offers a "stimulating effect" that aids concentration.

The level of concentration in water had a "negligible effect" on people's uptake of the fluoride ion - responsible for increased risk of fractures, they said.

That feeds worries about the other effect of lots more clearing: a new concentration of risk.

The warming effect is similar to that predicted from an elevation of the atmospheric CO2 concentration to 720 ppm.
