This was in the Herald this morning:
Icebergs coming en masse
More than 100 Antarctic icebergs – and possibly even hundreds of them – are floating towards New Zealand.
An Australian Antarctic Division glaciologist, Neal Young, said yesterday that the ice chunks, spotted in satellite photos, had passed the Auckland Islands and were heading towards the South Island, 450km northeast.
He said more than 100 icebergs – some more than 200m across – were seen in just one cluster, indicating there could be hundreds more.
Dr Young said they were the remains of a massive ice floe which split from Antarctica in rising sea and air temperatures resulting from global warming.

I think it’s exciting that we might see giant icebergs again, because it’s dramatic. However, the assumption that their close approach is connected with warming is odd, since the appearance of ice in my gin and tonic indicates just the opposite—a cooling trend. As you sail to Antarctica, the appearance of icebergs in the sea certainly confirms a cooling trend. A reasonable person, on hearing that icebergs appear because of warming, surely considers enquiring whether it’s actually because of cooling.
Dr Young’s easy attribution of the calving of these icebergs to “global warming” is unlikeable and unconvincing. More likely is that, as usual, the ice shelf reaches such a length (through continual plentiful production of ice, please note!) that the ocean waves can move it about with sufficient force to snap it off. If warming was causing melting, what would survive to embark on a voyage to anywhere?
It is equally likely that, because of cooling seas, the icebergs now survive the long voyage to New Zealand!
I know of no evidence supporting a global rise in temperature recently. Certainly, no more than perhaps 0.2°C, something like that, in the few months which might have influenced the calving. In the Antarctic, such a rise might get you up to around minus eleventy five which is dreadfully chilly and won’t melt anything. There’s nothing abnormal going on here. Might we not reasonably expect the Herald to know this and to question the AFP story?
They have let us down.
