"100 metres" Williams is already four metres down in four years

It's four years since this exchange with the ABC's science guru and leading warmist, Robyn Williams:

Andrew Bolt: I'm telling you, there's a lot of fear out there. So what I do is, when I see an outlandish claim being made...so Tim Flannery suggesting rising seas this next century eight stories high, Professor Mike Archer, dean of engineering at the University of NSW…

Robyn Williams: Dean of science.

Andrew Bolt: Dean of science...suggesting rising seas this next century of up to 100 metres, or Al Gore six metres. When I see things like that I know these are false. You mentioned the IPCC report; that suggests, at worst on best scenarios, 59 centimetres.

Robyn Williams: Well, whether you take the surge or whether you take the actual average rise are different things.

Andrew Bolt: I ask you, Robyn, 100 metres in the next century...do you really think that?  Robyn Williams: It is possible, yes. The increase of melting that they've noticed in Greenland and the amount that we've seen from the western part of Antarctica, if those increases of three times the expected rate continue, it will be huge.

The red dot marks the date that Williams claimed the seas could rise 100 metres this century, or a metre a year on average, thanks to man-made warming.

If the rest of the century is like the four years that followed, he'll be about 99.98 metres short.
