It seems Sydney's thinking Catholics will soon be rePelled, comPelled or exPelled. Anne Gilbert, Northmead, April 1. The notion that humans have somehow engineered the warming of the planet shows how egotistical we are.

There is only accusation and conjecture.
All evidence is purely circumstantial.
Remember, the last ice age came and went without any help from us. The eruption of Mount Pinatubo in 1991 emitted more ozone-destroying chemicals than humans have in their entire history. As did the eruption of Mount St Helens. Peter Maresch, Lane Cove, March 31. George W. Bush has not changed his tune one little bit on global warming.
