Perspective: The Role of Offsets in Climate Change Legislation

Green Car Congress

This article shows that including offsets in climate change legislation would likely make an emissions program more cost-effective by: (a) providing an incentive for non-regulated sources to generate emission reductions; and (b) expanding emission compliance opportunities for regulated entities. Assuming the offset is legitimate—i.e.,

UK study provides observational evidence linking ocean circulation to weather and decadal-scale climate change

Green Car Congress

The change to the new set of climatic conditions is associated with a cooling of the Atlantic, and is likely to bring drier summers in Britain and Ireland; accelerated sea-level rise along the northeast coast of the United States; and drought in the developing countries of the Sahel region. — McCarthy et al.
