In 2008 the growth rate in the fossil fuel carbon dioxide emissions was smaller than in the preceding five years, but it was still over 2 %.

These are — and dramatic changes in the rate of growth of human population (the «generators» of the human emissions)-- an upper limit to the amount of carbon contained in all the fossil fuels remaining on our planet

It ignores two real physical constraints on human CO2 emissions (plus resulting warming) in the future: — changes in human population growth rates — total carbon contained in remaining fossil fuel reserves

While the above analysis yields good results for by tying past climate change to increases in human CO2 emissions, it should be cautioned that the suggested exponential time relation is not suitable for projecting the future over longer time periods, because of possible changes in human population growth rates and absolute limitations on carbon available in remaining fossil fuels.

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.

This course, created by a team of energy experts, was unveiled on Tuesday in a report for the United Nations that explores the technological paths available for the world's 15 main economies to both maintain reasonable rates of growth and cut their carbon emissions enough by 2050 to prevent climatic havoc.

In a somewhat hopeful note, the report found that in 2014 and 2015, carbon dioxide emissions growth rates slowed as economic growth became less carbon - intensive.

Yet even if the high price of energy from fossil fuels and power plants combines with regional climate initiatives to slow the current rate of growth somewhat, we will probably hit 11 gigatonnes of carbon emissions per year by 2020.

In developing and emerging economies, slowing the rate of growth of using conventional transport modes with relatively high ‐ carbon emissions for passenger and freight transport by providing affordable, lowcarbon options could play an important role in achieving global mitigation targets.

There are two primary externalities that result from our emissions of carbon dioxide into the atmosphere — 1) an enhancement of the greenhouse effect, which results in an alteration of the energy flow in the earth's climate and a general tendency to warm the global average surface temperature, and 2) an enhancement of the rate of photosynthesis in plants and a general tendency to result in more efficient growth and an overall healthier condition of vegetation (including crops).

The difference between Professor Nordhaus's optimal carbon tax policy and a fifty - year delay policy is insignificant economically or climatologically in view of major uncertainties in (1) future economic growth (including reductions in carbon emissions intensity); (2) the physical science (e.g., the climate sensitivity); (3) future positive and negative environmental impacts (e.g., the economic «damage function»); (4) the evaluation of long - term economic costs and benefits (e.g., the discount rate); and (5) the international political process (e.g., the impact of less than full participation).

We're at about 30 billion tons of carbon dioxide emissions a year — and notwithstanding the global economic slowdown, probably poised to rise 2 % per year (the exact future growth rate is quite hard to project because it depends so much on what China does and how quickly peak oil kicks in).

Developed nations typically have high carbon dioxide emissions per capita, while some developing countries lead in the growth rate of carbon dioxide emissions.

When combined, these policies would yield a smaller, less powerful government; a tax code more conducive to investment and growth; and the emissions reductions the law says we must achieve...
