[[#footnote-007-backlink|1]] Note that GMST and GSAT are physically distinct but closely related quantities ([[#1.4.1|Section 1.4.1]] and Cross-Chapter Box 2.3).

<div id="footnote-006" class="_idFootnote"></div>

[[#footnote-006-backlink|2]] As old as the longest continuous climate records, which are based on the ice core from EPICA Dome Concordia, Antarctica. Polar ice cores are the only paleoclimatic archive providing direct information on past greenhouse gas concentrations.

<div id="footnote-005" class="_idFootnote"></div>

[[#footnote-005-backlink|3]] The labels of ‘mitigation’, ‘adaptation’ and ‘means of implementation and support’ are provided here for guidance only, with no presumption about the actual legal content of the paragraphs and to what extent they encompass mitigation, adaptation and means of implementation in its entirety.

<div id="footnote-004" class="_idFootnote"></div>

[[#footnote-004-backlink|4]] Paragraph 37b in 19/CMA.1 in FCCC/PA/CMA/2018/3/Add.2, pursuant decision 1/CP.21, paragraph 99 of the adoption of the PA in FCCC/CP/2015/10/Add.1, available at: https://unfccc.int/documents/193408 .

[[#footnote-002-backlink|6]] Decision 1/CP.23, in FCCC/CP/2017/L.13, available at [https://unfccc.int/resource/docs/2017/cop23/eng/l13.pdf https://unfccc.int/resource/docs/2017/cop 23/eng/l13.pdf] .

<div id="footnote-001" class="_idFootnote"></div>

[[#footnote-001-backlink|7]] Box 1.2 reproduces the temperature metrics as they appeared in the respective SPMs of the Special Reports. In AR6 long-term changes of GMST (global mean surface temperature) and GSAT (global surface air temperature) are considered to be equivalent, differing in uncertainty estimates only (Cross-Chapter Box 2.3).

<div id="footnote-000" class="_idFootnote"></div>

[[#footnote-000-backlink|8]] Note that the 5–95% is a ''very likely'' range (see Box 1.1 on the use of calibrated uncertainty language in AR6), though if this is purely a multi-model likelihood range, it is generally treated as ''likely'' , in the absence of other lines of evidence.
