Earth-Sun system energetics and global warming
Article Abstract:
Increasing the Earth-Sun distance is discussed as a means to offset the projected 3-degrees Centigrade increase in global warming around the year 2000. Global warming depends on the rate at which the Earth receives solar radiation, and this rate varies as the inverse square of the Earth-Sun distance. Calculations showed that it would require an enormous amount of energy to pull the Earth into a larger orbit. Perhaps science can supply that energy requirement in the future. Effects on the time period and the speed of revolution of the Earth would have to be studied carefully.

Valuation of global afforestation programs for carbon mitigation
Article Abstract:
Traditional cost-benefit analysis do not appear to be effective in resolving long-term environmental problems, particularly defective cost and benefit data, the use of discount rates and the requirement of marginal cost-benefit analysis. Current cost-benefit analyses pose technical setbacks that may lead to an inaccurate assessment of the efficacy of a global afforestation program in terms of its social and economic implications. An example of a plantation program for carbon mitigation and the widely variable valuation of its costs and benefits is discussed.

On "Valuation of Global Afforestation Programs for Carbon Mitigation" by Sten Nilsson
Article Abstract:
The proper measurement of the costs and benefits of afforestation programs through cost-benefit analyses ensures the wise use of resources over time. On the other hand, the non-application of cost-benefit analysis for such programs may lead to a subjective valuation of forest-related projects, programs or strategies. The uncertainty/risk posed by cost-benefit analyses is inevitable, while using real rate of discount will result in a consistent analysis and aggregation.
