What is the greenhouse effect?

A. Henderson-Sellers

Research output: Contribution to journalArticlepeer-review


The greenhouse effect is a physical reality. Increases in greenhouse gases have been measured and are predicted as continuing. The slight (approx. 0.6°C) global warming detected so far this century seems very likely to be the direct result of the increased burden of greenhouse gases in the Earth's atmosphere but this cannot yet be asserted with confidence. The problem of what course of action, including "do nothing', is now required is not appropriately addressed to climate scientists since it involves a cost-related value judgement. Society must decide whether or not to initiate delaying or coping strategies now. There are two essential pre-requisites to this decision: 1) adequate dissemination of information and 2) a choice of planning strategies. Both of these are within our grasp. -from Author
