Errata in the IPCC Special Report on the Ocean and Cryosphere in a Changing Climate (SROCC) Handled in accordance with the IPCC protocol for addressing possible errors in IPCC Assessment Reports, Synthesis Reports, Special Reports and Methodology Reports: https://www.ipcc.ch/site/assets/uploads/2018/09/ipcc_error_protocol_en.pdf

Summary for Policymakers A.3.1, Line 1: Replace '1902–2015' with '1902–2010' and replace 'likely' with 'very likely' Figure SPM3.d: Replace Figure SPM3.d with Errata Figure SPM3.d. The figure has been updated to correct the lines for the transition ranges and the corresponding alignment of confidence levels B.6.2, Line 1: Insert ‘risks’ before ‘increase with further warming’

Chapter 1

Figure 1.1: Replace Figure 1.1 with Errata Figure 1.1. Panel f equation given as 'FAR = 1 – Pant / Pnat' has been corrected to read 'FAR = 1 – Pnat / Pant'

Figure 1.1 Caption, Line 11: replace 'FAR = 1 – Pant / Pnat' with 'FAR = 1 – Pnat / Pant'

Chapter 3 Figure 3.3: Replace Figure 3.3 with Errata Figure 3.3. The sea ice concentration trend unit ‘°C per decade’ has been corrected to read '% per decade'

Chapter 4 Section 4.2.3.2, page 352, paragraph 1, line 1: Replace ‘16 cm (5–95 percentile; 2–37 cm)’ with ‘10 cm (5–95 percentile; 2–23 cm)’

Chapter 5 Figure 5.16: Replace Figure 5.16 with Errata Figure 5.16. The figure has been updated to correct the alignment of the color gradient, and associated confidence levels, to the temperature scale and the placement of the line 'Present day'.
