It notes that: 80 % of carbon dioxide emissions come from only 19 countries; the amount of carbon dioxide per US$ 1 GDP has dropped by 23 % since 1992, indicating some decoupling of economic growth from resource use; nearly all mountain glaciers around the world are retreating and getting thinner; and sea levels have been rising at an average rate of about 2.5 mm per year since 1992.

At the core of the issue is the fact that, as far as we know, CO ₂ levels are currently very unusual for the Late Pleistocene, about twice the average, while temperatures, sea levels, and ice are within Holocene variability range.

The carbon fee would be an insurance policy aimed at rapidly dropping the emissions blamed with increasing the average temperature of the world's land and atmosphere, which are linked by scientists to increased melting of glaciers and icecaps and rising sea levels that pose a direct threat to south Louisiana, he said.

Plants live on soils over land (sea plants are lucky, plenty of CO2 there), where the average CO2 level is 30 - 40 ppmv higher than in the bulk atmosphere, even larger if you measure at ground level.
