Claim: “Recent computer forecasts suggest that if greenhouse gas emissions continue at a high level, parts of Antarctica could break up rapidly, causing the ocean to rise six feet or more by the end of this century.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Over the 21st century, the IPCC projects that in a very high emissions scenario the sea level could rise by 61–110 cm.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: A rapid collapse of the West Antarctic Ice Sheet could raise sea level by 3.3 metres (11 ft).

Relevance (1 = gold evidence, 0 = mined hard negative): 1
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: Global warming is projected to have a number of effects on the oceans.

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: 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: [citation needed] By 2100 the overall level of the Mediterranean could rise between 3 to 61 cm (1.2 to 24.0 in) as a result of the effects of climate change.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
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: Scientists have found that the flow of these ice streams has accelerated in recent years, and suggested that if they were to melt, global sea levels would rise by 1 to 2 m (3 ft 3 in to 6 ft 7 in), destabilising the entire West Antarctic Ice Sheet and perhaps sections of the East Antarctic Ice Sheet.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Around 1.5°C to 2°C of global warming," irreversible instabilities could be triggered in Antarctica and "Greenland ice sheet, resulting in multi-metre rise in sea level.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: A study in 2015 found that assuming cumulative fossil fuel emissions of 10 000 gigatonnes of carbon, the Antarctic Ice Sheet could melt completely over the following millennia, contributing 58 m to global sea-level rise, and 30 m within the first 1000 years.
