Paul Kench, has discovered new evidence of sea-level variability in the central Indian Ocean. The study, which provides new details about sea levels in the past, concludes that sea levels in the central Indian Ocean have risen by close to a meter in the last two centuries. Kench says, "We know that certain types of fossil corals act as important recorders of past sea levels. By measuring the ages and the depths of these fossil corals, we are identifying that there have been periods several hundred years ago that the sea level has been much lower than we thought in parts of the Indian Ocean.

FACT CHECK: Scientists Caught Tampering With Raw Data To Exaggerate Sea Level Rise?
A survey of maritime infrastructure engineers by University of Rhode Island researchers found that the rising sea level is often not factored into designs of ports, breakwaters, fishing piers and other coastal infrastructure. In , Becker and graduate student Benjamin Sweeney surveyed 85 engineers at consulting firms, port authorities and government agencies with experience working on port infrastructure projects in the United States. They also don't want to have to weigh potentially conflicting guidance from local, state or federal agencies. Becker said that without guidance, port engineers are more likely to disregard sea level change projections entirely. Naval War College. But scientists understand that sea levels are actually rising and that there will be ramifications, and it's going to make things much more expensive to not factor those changes into designs now. The survey also examined the factors that influenced whether engineers incorporate sea level rise into their designs.
Short-lived greenhouse gases cause centuries of sea-level rise
Tide gauge measurements show that global sea level rise began around the start of the 20th century. This acceleration is due mostly to human-caused global warming , which is driving thermal expansion of seawater and the melting of land-based ice sheets and glaciers. Projecting future sea level is challenging, due to the complexity of many aspects of the climate system and to time lags in sea level reactions to Earth temperature changes. As climate research into past and present sea levels leads to improved computer models , projections have consistently increased.
