In light of their findings, the three researchers state that "at best, the determination and attribution of global-mean sea level change lies at the very edge of knowledge and technology," and that "it remains possible that the database is insufficient to compute mean sea level trends with the accuracy necessary to discuss the impact of global warming -- as disappointing as this conclusion may be." (emphasis mine) As a result, they conclude that the altimetry result is "currently untestable against in situ datasets."

Thought this was worth noting since rising sea levels are one of the key scare tactics propagated by climate alarmists.
