YESTERDAY I welcomed into the world my fourth grandchild. It should be a day of great celebration, but I am saddened by the world into which this child is being born because of our inactivity to prevent a climate catastrophe. The last 30 years have seen the hottest 20 years on record, almost certainly due to the fact that we have allowed the atmospheric carbon dioxide concentration to rise from 275 parts per million (PPM) to over 400 PPM in the last 200 years. We have gone beyond the point where global warming can be restricted to 1.5 degrees, and the only question is how close we are to the tipping point beyond which warming is uncontrolled. Ocean temperatures have risen faster than atmospheric temperatures and we are experiencing major ecological changes in our coastal areas, particularly the Great Barrier Reef but also Tasmania. More dangerously, we are now starting to see glacial melting in the Antarctic which holds many times the amount of ice as in the Arctic. This could raise sea levels many metres, causing massive dislocation and forced migration. Australia is clearly more exposed to global warming, with consequent extended droughts, more frequent wildfires and mosquito-borne infections, than most countries. The current government seems to be totally oblivious to this threat, recognised by 99 per cent of the world's climate scientists. I wish I could reassure my new grand-daughter that we recognise the perilous situation into which we have descended by failing to heed the warnings over the last 30 years.
