Claim: Ocean levels have been rising for the last 20,000 years[…] No climate scientist can tell you when natural sea level rise stopped and man-made sea level rise began.

Passage: Since the last glacial maximum about 20,000 years ago, the sea level has risen by more than 125 metres (410 ft), with rates varying from less than a mm/year to 40+ mm/year, as a result of melting ice sheets over Canada and Eurasia.

Passage: The rate of rise started to slow down about 8,200 years before present; the sea level was almost constant in the last 2,500 years, before the recent rising trend that started at the end of the 19th century or in the beginning of the 20th.

Passage: In 2018, scientists concluded that high sea levels some 125,000 years ago, which were 6–9 m (20–30 ft) higher than today, were most likely due to the absence of the WAIS, and found evidence that the ice sheet collapsed under climate conditions similar to those of today.

Passage: The sea level has risen more than since the [[Last Glacial Maximum]] about 20,000 years ago.

Passage: Human-induced warming and associated sea level rises are expected to continue through the 21st century...

Passage: However, Greg Holland from the National Center for Atmospheric Research, who reviewed the study, noted: “There is no doubt that the sea level rise, within the IPCC, is a very conservative number, so the truth lies somewhere between IPCC and Jim.” In addition, one 2017 study's scenario, assuming high fossil fuel use for combustion and strong economic growth during this century, projects sea level rise of up to 132 cm (4.3 ft) on average — and an extreme scenario with as much as 189 cm (6.2 ft), by 2100.

Passage: From 1961 to 2003, the global ocean temperature has risen by 0.10 °C from the surface to a depth of 700 m. There is variability both year-to-year and over longer time scales, with global ocean heat content observations showing high rates of warming for 1991 to 2003, but some cooling from 2003 to 2007.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Continued carbon dioxide emissions from fossil fuel sources could cause additional tens of metres of sea level rise, over the next millennia, and the available fossil fuel on Earth is even enough to ultimately melt the entire Antarctic ice sheet, causing about 58 m (190 ft) of sea level rise.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Although previously it was thought that the polar ice caps were not contributing heavily to sea level rise (IPCC 2007), recent studies have confirmed that both Antarctica and Greenland are contributing a year each to global sea level rise.

Passage: For instance, a 2016 study led by Jim Hansen concluded that based on past climate change data, sea level rise could accelerate exponentially in the coming decades, with a doubling time of 10, 20 or 40 years, respectively, raising the ocean by several meters in 50, 100 or 200 years.
