Climate scientists says projections of the rise of sea level are overblown

Washington Times:

For years, climate prognosticators have warned that human-caused global warming is fueling catastrophic sea-level rise, but now climatologist Judith Curry is rocking their boat.

In her latest paper, Ms. Curry found that the current rising sea levels are not abnormal, nor can they be pinned on human-caused climate change, arguing that the oceans have been on a “slow creep” for the last 150 years — before the post-1950 climb in carbon-dioxide emissions.

“There are numerous reasons to think that projections of 21st-century sea level rise from human-caused global warming are too high, and some of the worst-case scenarios strain credulity,” the 80-page report found.

Her Nov. 25 report, “Sea Level and Climate Change,” which has been submitted for publication, also found that sea levels were actually higher in some regions during the Holocene Climate Optimum — about 5,000 to 7,000 years ago.

“After several centuries of sea level decline following the Medieval Warm Period, sea levels began to rise in the mid-19th century,” the report concluded. “Rates of global mean sea level rise between 1920 and 1950 were comparable to recent rates. It is concluded that recent change is within the range of natural sea-level variability over the past several thousand years.”

Such conclusions are unlikely to find favor with the global-warming movement, or within the academic climate “consensus,” where some experts have predicted that mean sea level could rise by five to 10 feet by the end of the 21st century.

She said the problem is that the disaster scenarios are driven by the most extreme forecasts of carbon-dioxide emissions, known as RCP8.5, which she and other critics have described as so extreme as to be implausible.

“[President] Trump, he said something about people talking about the extreme scenarios — well, they are,” Ms. Curry told The Washington Times. “Consideration of extreme scenarios has some value, but they’re portrayed as the expected outcome, and that’s really not useful.”

She argued that a more appropriate estimate would be about 0.2 to 1.5 meters, or six inches to five feet, and that anything over two feet is “increasingly weakly justified.” Mean sea level has risen by about seven to eight inches since 1900.

Curry says areas, where most of the project flooding is expected, are those where the land mass has sunk and not because the sea level is rising.  She gave New Orleans as an example.

One of the serious problems with the global warming theory is that their projections of future events are based on invalid assumptions, and when those projections are not met, they are unable to explain which of their assumptions was invalid.  I suspect they are overrating the negative effects of rising CO2.
