Claim: The consensus among scientists and policy-makers is that we’ll pass this point of no return if the global mean temperature rises by more than two degrees Celsius.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: The current trajectory of global greenhouse gas emissions is not consistent with limiting global warming to below 1.5 or 2 °C, relative to pre-industrial levels.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: In 2018 the IPCC published a Special Report on Global Warming of 1.5 °C which warned that, if the current rate of greenhouse gas emissions is not mitigated, global warming is likely to reach 1.5 °C (2.7 °F) between 2030 and 2052, risking major crises.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: An increase of global temperature by more than 2°C has come to be the majority definition of what would constitute intolerably dangerous climate change with efforts to limit the temperature increase to 1.5°C above pre-industrial levels per the Paris Agreement.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The Paris Agreement's long-term temperature goal is to keep the increase in global average temperature to well below 2 °C above pre-industrial levels; and to pursue efforts to limit the increase to 1.5 °C, recognizing that this would substantially reduce the risks and impacts of climate change.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Some researchers have argued that the most serious consequences of global warming might be avoided if global average temperatures rose by no more than 2 °C (3.6 °F) above pre-industrial levels (1.4 °C above present levels).

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Although the parties to the UNFCCC have agreed that deep cuts in emissions are required and that global warming should be limited to well below 2 °C (3.6 °F) in the Paris Agreement of 2016, the Earth's average surface temperature has already increased by about half this threshold and current pledges by countries to cut emissions are inadequate to limit future warming.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: 1995 saw the creation of the phrase "preventing dangerous anthropogenic interference with the climate system" (also called "avoiding dangerous climate change") first appeared in a policy document of a governmental organization, the IPCC's Second Assessment Report: Climate Change 1995. and in 1996 the European Union adopt a goal of limiting temperature rises to a maximum 2 °C rise in average global temperature.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: In 2015, all (then) 196 parties to the convention came together for the UN Climate Change Conference in Paris 30 November - 12 December and adopted by consensus the Paris Agreement, aimed at limiting global warming to less than two degrees Celsius, and pursue efforts to limit the rise to 1.5 degrees Celsius.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: To limit global temperature to a hypothetical 2 degrees Celsius rise would demand a 75% decline in carbon emissions in industrial countries by 2050, if the population is 10 billion in 2050.
