What Climate Policy Can a Utilitarian Justify?

This essay sketches out what a utilitarian should support when considering global warming along with what measures can be recommended to political leaders for utilitarian reasons. If we estimate the utility of the great advantages that any ambitious climate policy might create in the name of poverty reduction in the present, I will show how a decision can be made in favor of a vigorous climate policy based on such estimates. My argument is independent of the truth of the claims of climate sceptics. Until now, the debate has neglected the double effects of a vigorous climate policy that not only avoids risks of damages but also creates utility. In conclusion, three strategies of a climate policy legitimized by utilitarianism will be introduced: (1) Utilitarianism favors global emissions trading in comparison with a global CO₂ tax. (2) Utilitarianism calls for this trade to be introduced while, at the same time, investments in renewable energies should be increased. (3) Furthermore, utilitarianism favors a policy that aims to slow down the rate of population growth.     

Organic compounds and trace metals of anthropogenic origin in sediments from Montego Bay,Jamaica: assessment of sources and distribution pathways

Surface sediments throughout Montego Bay, Jamaica were collected in 1995 and analyzed for their trace metal and trace organic contaminant content. A variety of trace metals, petroleum hydrocarbons, polycyclic aromatic hydrocarbons, coprostanol as well as chlorinated hydrocarbons such as pesticides and polychlorinated biphenyls were detected and provide evidence for several anthropogenic inputs to the bay. Two main sources of these chemicals are the Montego River and the North Gully, the latter being more significant. Particle-associated pollutants were found to be distributed along the Montego River plume, as well as being transported by the prevailing water currents to the South-Western sections of the bay, probably through re-suspension of enriched fine sediments from the North Gully outfall area.
