Tide Gauge Location and the Measurement of Global Sea Level Rise

Technical Rating: star star star
This open access paper by Beenstock et al show that tide gauge locations in 2000 were independent of sea level rise (SLR) as measured by satellite altimetry. Therefore these tide gauges constitute a quasi-random sample, and inferences about global SLR obtained from them are unbiased. The global mean SLR is 0.39–1.03 mm/year. The paper says "the claim that sea levels are rising globally (IPCC 2014) is an artifact induced by the use of imputed data."

What is Happening to Sea Levels?

Technical Rating: star
Some computer models predict 1 metre sea level rise by the end of the 21st century. However, the actual experimental data shows, at most, a slow and modest increase in sea levels, which seems completely unrelated to CO2 concentrations. The main estimates of long-term sea level changes are based on data from various tidal gauges located across the globe. These estimates apparently suggest a sea level rise of about 1 to 3 mm a year since records began. Importantly, the rate still seems to be about the same as it was at the end of the 19th century, even though carbon dioxide emissions are much higher now than they were during the 19th century.

The Dutch and the Sea Level Rise

Technical Rating: star
There is currently a debate in the Netherlands about the future rate of sea level rise. Independent researchers estimate that the sea level will rise 20 cm to the end of the century, while the IPCC expects about 50 cm. A government commission recommends an expenditure of 80 billion euros over the next 40 years to raise dikes based on a high case sea level rise prediction of 110 cm by 2100.

U.S. Secretary of State Continues to Promote Flagging Climate Catastrophe

Technical Rating: star
The Obama administration continues to push its climate change agenda, with U.S. Secretary of State John Kerry suggesting while in Jakarta, Indonesia recently that the islands are at risk from rising sea levels. His faith in rising sea levels, however, bears little relationship to scientific fact. Referring to sea levels over the past 50 years, Dr. Michaels says "there remains no evidence for a climate-related acceleration."

Highly Over-Hyped: Greenland's and Antarctica's Impacts on Sea Level

Technical Rating: star
Sherwood, Keith and Craig Idso of CO2 Science examnes recent claims that recent discharges of glacial ice from Greenland and Antarctica may accelerate sea level rise. They show that there has been no net loss of ice at either location that would contribute to sea level rise.
