During the current interglacial, sea level has risen 130 metres in 14,000 years, a rate far higher than the most exaggerated model for human-induced global warming.

During the last interglacial, there were a number of exceptionally cold snaps and temperature rose by as much as 20-degrees Celsius in 15 years after one of these periods. There were also alternating cool, windy, dry times and warm, wet times.

Some 6,000 years ago sea level was 2 metres higher than at present and it was at least 3-degrees warmer than now.

Cool times led to desertification and the collapse of great civilisations and warm times led to a thriving of humans.

The temperature and rate of temperature change in the Minoan, Roman and Mediaeval Warmings were far greater than today.

In the Roman Warming, grapes and citrus were grown as far north as Hadrian's Wall.

The Roman Warming came to a sudden end in the middle of the 6th century AD, due to a coincidence of solar, extraterrestrial and volcanic activities.

The Mediaeval Warming commenced with a very active sun.

Between 900 and 1300 AD, it was warmer, times were prosperous and generational wealth was used to build the great cathedrals, monasteries and universities of Europe.

The Vikings colonised Newfoundland and called in Vinland. No grapes could survive the cool climate of Newfoundland today.

In the Mediaeval Warming, wheat, barley, sheep and cattle were grown in Greenland in places now covered by ice.

Atmospheric temperature was at least 5-degrees warmer than at present.

A solar change in 1280 AD led to the Little Ice Age.

It took 23 years to change from the Mediaeval Warming to the Little Ice Age.

There was crop failure, starvation and murderous climate refugees roamed Europe.

The stressed population succumbed to the plague and there was massive depopulation.

During times of decreased sunspot activity, it was far colder, there was civil unrest, starvation, ice-fairs on rivers and increased cloudiness.

The Little Ice Age ended about 1850. Since then, the Earth has warmed at the same rate from 1860-1880, 1910-1940 and 1975-1998.

Atmospheric temperature has been decreasing in the 21st century, despite an increase in atmospheric carbon dioxide.

The climate models show that temperature should have been increasing in the 21st century.

This disconnect again shows that carbon dioxide does not drive temperature and that models of very complex chaotic natural systems should be viewed with great caution.

Yes, I just copied it without comment from your ABC...


Shurely shome mishtake.


Re maths - you assume a steady, even rate of change - again. The modeller's curse. Nothing has aver changed steadily, at a even rate over 1. 10, 100 years, let alone 14,000.

Sorry, pants remain well pressed, dry and cool.

The maximum slope of that graph equates to 0.008 metres per annum.

The current trend is about 0.06 metres per annum, as shown in the graph below from the Copenhagen Sythesis Report.

You may also note that the current rate of sea level change fits in with the more extreme predictions of IPCC 4AR (6 metres by 2100). It follows very closely with the "Holy Sh1t!" scenario.

I thankyou for explaining all of this Muso, it can get confusing with the denialist camp doing their best to undermine the scientific facts with lies.
People like Plimer and those that believe his lies care more about their hip pocket than they do about our earths future.
