In its independent analysis, NOAA pegged it at 0.83 degrees C warmer.

“The measured value is consistent with the trend in global average surface temperatures that has been observed during the past few decades,” NASA noted.

” Conclusions Fairbridge’s pioneering research led, not to a global eustatic curve as he had anticipated, but to the recognition that the pattern of relative sea-level change in the Australian region differed from that observed in the Atlantic.

A series of seminal sea-level studies were undertaken in the following 25 years.

During the coldest days of the last ice age (known as a glacial maximum) 20,000 years ago, the oceans were 125m lower than today.

They peaked at around 1 -2 meters higher than present between 90 years ago, and have been trending down ever since.

Most of the east coast of New South Wales and west coast of Western Australia were classed as relatively stable.

Although most parts of the Australian continent reveals a high degree of tectonic stability, research conducted since the 1970s has shown that the timing and elevation of a Holocene highstand varies systematically around its margin.

He also continues to work as a science and environmental journalist with more than 30 years of experience producing content for major publications.

Worse, if you look at the data, the rate is closer to zero. Clearly there are many details yet to be worked out about sea-levels.

“Bryant (1992) reviewed the variable sea-level highstands of the last interglacial (based on the analysis of Murray-Wallace and Belperio, 1991) and mid-Holocene around Australia and found that there was possible downwarping of northern Australia and up warping along the southern edge of the continent (including Tasmania).

This is attributed primarily to variations in the timing of the response of the ocean basins and shallow continental shelves to the increased ocean volumes following ice-melt, including a process known as ocean siphoning (i.e.

glacio-hydro-isostatic adjustment processes).” The reviewers call for empirical evidence of the past, so we can predict the future.

Relatively cool conditions in the Arctic – see the blue tones in the global map at the top of this story — helped tamp down the global average in August.
