From JERRY VANCLAY
Greenhouse effect, global warming and climate change are often used
interchangeably (This Week, 11 April), but we should emphasise change rather
than warming. Too many people envisage a benevolent warming, bringing the
Mediterranean to the Baltic. Unfortunately, it won’t be like that, but will
probably be more erratic. Consider the El Nino Southern Oscillation, apparently
triggered by a small warming of the Pacific, which causes droughts, floods
and severe storms across half the world. Please, can we call it climate
change, and not global warming?
