I know that some of our readers are meteorologists so I would be particularly pleased if they would comment – however harshly!
On the premise that the Antarctic ice cap is melting, (and evidence of bergs the size of Tasmania breaking away would seem conclusive to me) I believe that major climate change is happening right now.
The driest continent on Earth is Antarctica, all the usual air moisture being locked into ice and snow. Now that the ice is melting it stands to reason that the air is more humid than it was.
If that is correct, the prevailing west to south-west winds are carrying this damper air up to southern hemisphere landmasses.

This seems to me to be happening more and more often. In more than half a century of sailing I used to expect one of these cool changes to come every seven to 10 days in summer. Now we are getting them every two to four days.
The winds are heavier, storms more frequent and nastier and it is significantly colder.
Since Annie and I live in Sydney we have always known that we were in one of the world’s temperate zones. But I believe now that the temperate zones are having to work much harder at balancing out the cold and moisture from the south and the tropical heat in the north.
- Has there been any research into these questions?
- Is it compatible with global warming?
- Is my theory – that increased moisture is being brought to dry countries like Australia – backed by scientific observation?
I look forward to your comments.
