Claim: Climate scientist James Hansen: "we have until perhaps 50 years from now," or maybe a little longer "and at that point, we are looking at 10, 20, 30 feet of sea-level rise."

Passage: George Monbiot reports "The IPCC predicts that sea levels could rise by as much as 59 centimetres (1.94 ft) this century.

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.

Passage: According to the Fourth (2017) National Climate Assessment (NCA) of the United States it is very likely sea level will rise between 30 and 130 cm (1.0–4.3 feet) in 2100 compared to the year 2000.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: For example, in 2007 the Intergovernmental Panel on Climate Change (IPCC) projected a high end estimate of 60 cm (2 ft) through 2099, but their 2014 report raised the high-end estimate to about 90 cm (3 ft).

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.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: According to 2007 estimates by the International Panel on Climate Change (IPCC), “global average sea level will rise between 0.6 and 2 feet (0.18 to 0.59 meters) in the next century.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Sea level rise will continue over many centuries.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The United Nations Intergovernmental Panel on Climate Change predicts that sea levels will rise by about 50 cm (20 in) by 2100 due to global warming and a further rise would be inevitable.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The fact that the IPCC estimates did not include rapid ice sheet decay into their sea level predictions makes it difficult to ascertain a plausible estimate for sea level rise but a 2008 study found that the minimum sea level rise will be around by 2100.

Passage: James E. Hansen (1941 --), American climatologist

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