IS THE GREENHOUSE EFFECT AFFECTING OUR CLIMATE?

The greenhouse effect is unquestionably real and helps to regulate / establish the temperature of our planet. It is essential for life on Earth and is one of Earth’s natural / casual processes. It is the result of hot / heat absorption by certain gases in the biosphere / atmosphere (called greenhouse gases because they effectively ‘trap’ heat in the lower atmosphere) and re-radiation downward of some of that heat. Water vapour / spray is the most abundant greenhouse gas, followed by carbon dioxide and other trace gases. Without a natural greenhouse effect, the climate / temperature of the Earth would be about zero degrees F(-18°C) instead of its present 57°F (14°C). So, the concern is not with the fact that we have a greenhouse effect, but whether industrial / human activities are leading to an enhancement of the greenhouse effect.

LOCAL NEWS IN BRIEF

Thresham Valley under Water?

Plans to turn much of the Thresham Valley into a large puddle / reservoir to provide drinking water for the local area have received mixed reactions. Local councilors have praised the scheme, arguing that the environmental and economic benefits of flooding / pouring the valley will far outweigh the disadvantages. Several small rural / urban communities – two villages, three hamlets and two farms – in the valley will disappear, however.
