Sea-level rises are slowing, tidal gauge records show

The data doesn’t matter. We’re not basing our recommendations
on the data. We’re basing them on the climate models

Climate Change will result in a catastrophic global sea level
rise of seven meters. That’s bye-bye most of Bangladesh,
Netherlands, Florida and would make London the new Atlantis

We’ve got to ride this global warming issue.
Even if the theory of global warming is wrong,
we will be doing the right thing in terms of
economic and environmental policy.

President of the UN Foundation


The IPCC is the United Nations’ body most responsible for spreading panic about global warming and the body with a strong vested interest in keeping that panic alive.

A key climate indicator, in the quest to scare the world into accepting draconian climate policy and taxing emissions controls, is to use the fear of catastrophic sea-level rise.

Global sea level has risen 130 metres over the past 20,000 years, since the end of the last Ice Age, and at a steady rate of 3mm/year since the end of the Little Ice Age, from around 1850. However, alarmists would like you to believe that man’s 3% carbon dioxide emissions (versus nature’s 97%) are causing seas to rise ‘unprecedentedly’ and will have future catastrophic consequences by the end of this century unless we “Act Now”.

The latest IPCC report predicts sea levels will rise between 20 and 80 centimetres by the end of this century. Information based on an error bar of 400% and the IPCC’s “overheated” and widely criticised computer models.

Current empirical evidence and observational data of sea level rise trends tells a much less spooky story …

Sea-level rises are slowing, tidal gauge records show

ONE of Australia’s foremost experts on the relationship between climate change and sea levels has written a peer-reviewed paper concluding that rises in sea levels are “decelerating”.

The analysis, by NSW principal coastal specialist Phil Watson, calls into question one of the key criteria for large-scale inundation around the Australian coast by 2100 — the assumption of an accelerating rise in sea levels because of climate change.

Based on century-long tide gauge records at Fremantle, Western Australia (from 1897 to present), Auckland Harbour in New Zealand (1903 to present), Fort Denison in Sydney Harbour (1914 to present) and Pilot Station at Newcastle (1925 to present), the analysis finds there was a “consistent trend of weak deceleration” from 1940 to 2000.

Mr Watson’s findings, published in the Journal of Coastal Research this year and now attracting broader attention, supports a similar analysis of long-term tide gauges in the US earlier this year. Both raise questions about the CSIRO’s sea-level predictions.

Climate change researcher Howard Brady, at Macquarie University, said yesterday the recent research meant sea levels rises accepted by the CSIRO were “already dead in the water as having no sound basis in probability”.

“In all cases, it is clear that sea-level rise, although occurring, has been decelerating for at least the last half of the 20th century, and so the present trend would only produce sea level rise of around 15cm for the 21st century.”

Dr Brady said the divergence between the sea-level trends from models and sea-level trends from the tide gauge records was now so great “it is clear there is a serious problem with the models”.

“In a nutshell, this factual information means the high sea-level rises used as precautionary guidelines by the CSIRO in recent years are in essence ridiculous,” he said. During the 20th century, there was a measurable global average rise in mean sea level of about 17cm (plus or minus 5cm). Continue Reading »

A recently published study on sea level rises in Australia and New Zealand has some questioning the effect of climate change on the oceans.

Phil Watson, a coastal researcher with the New South Wales Office of Environment and Heritage, analysed data from four tide gauges, located at Fremantle, Sydney, Newcastle and Auckland, collected as far back as 1897.

He notes in his study that various long-term factors such as changes in the Moon’s orbit, El Nino events and the Pacific Decadal Oscillation affect sea levels on a periodic basis. To remove these effects, the data was converted into a 20-year moving average.

“The 20-year moving average water level time series through to 2000 clearly depict relative water level changes that are increasing over time, though at a reducing rate,” writes Watson in his study which appeared in the Journal of Coastal Research.

He says the most reliable gauges, located at Fremantle and Auckland, show an increase in sea level of approximately 120 millimetres between 1920 and 2000, or 1.5 millimetres per year. But this increase is reducing at a rate of between 0.02 and 0.04 millimetres per year.

“This decelerating trend was also evident in the detailed analysis of 25 US tide gauge records longer than 80 years in length,” he writes.

“Further research is required to rationalise the difference between the acceleration trend evident in the global sea level time-series reconstructions and the relatively consistent deceleration trend evident in the long-term Australasian tide gauge records.”

Tuvalu – Still Drowning After All These Years

Climatism comment : South Pacific Islands are not sinking, they are in fact growing. Claims they are sinking due to global warming driven sea level rise are opportunistic.
However, alarmists never cared for empirical data, especially when it debunks their spurious climate lies.
