Climate feedback processes in 2 × CO 2  are different from those in 1%CO 2 , and the equilibrium climate sensitivity (T 2× ) in 2 × CO 2  is different from the effective climate sensitivity (T 2×,eff ) in 1%CO 2 . The difference between T 2×  and T 2×,eff  is from −1.3 to 1.6 K, a large part of which can be explained by the difference in the ice-albedo and cloud feedback. The largest contribution is cloud SW feedback, and the difference in cloud SW feedback for 2 × CO 2  and 1%CO 2  could be determined by the distribution of the SAT anomaly which causes differences in the atmospheric thermal structure. An important factor which determines the difference in ice-albedo feedback is the initial sea ice distribution at the Southern Ocean, which is generally overestimated in 2 × CO 2  as compared to 1%CO 2  and observation. Through the comparison of climate feedback processes in 2 ×CO 2  and 1%CO 2 , the possible behaviour of the time evolution of T 2×,eff  is discussed."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383670319519020042","@type":"Researcher","foaf:name":[{"@value":"Tokuta Yokohata"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670319519020039","@type":"Researcher","foaf:name":[{"@value":"Seita Emori"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670319519020035","@type":"Researcher","foaf:name":[{"@value":"Toru Nozawa"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670319519020040","@type":"Researcher","foaf:name":[{"@value":"Tomoo Ogura"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670319519020037","@type":"Researcher","foaf:name":[{"@value":"Michio Kawamiya"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670319519020043","@type":"Researcher","foaf:name":[{"@value":"Yoko Tsushima"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670319519020034","@type":"Researcher","foaf:name":[{"@value":"Tatsuo Suzuki"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670319519020036","@type":"Researcher","foaf:name":[{"@value":"Seiji Yukimoto"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670319519020041","@type":"Researcher","foaf:name":[{"@value":"Ayako Abe-Ouchi"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670319519020032","@type":"Researcher","foaf:name":[{"@value":"Hiroyasu Hasumi"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670319519020038","@type":"Researcher","foaf:name":[{"@value":"Akimasa Sumi"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670319519020033","@type":"Researcher","foaf:name":[{"@value":"Masahide Kimoto"}]}],"publication":{"publicationIdentifier":[{"@type":"EISSN","@value":"16000870"}],"prism:publicationName":[{"@value":"Tellus A: Dynamic Meteorology and Oceanography"}],"dc:publisher":[{"@value":"Stockholm University Press"}],"prism:publicationDate":"2008-01-01","prism:volume":"60","prism:number":"5","prism:startingPage":"946"},"reviewed":"false","dcterms:accessRights":"http://purl.org/coar/access_right/c_abf2","url":[{"@id":"https://www.tandfonline.com/doi/pdf/10.1111/j.1600-0870.2008.00345.x"}],"createdAt":"2008-08-13","modifiedAt":"2025-10-16","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360004236557375872","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Sources of Spread in Multimodel Projections of the Greenland Ice Sheet Surface Mass Balance"}]},{"@id":"https://cir.nii.ac.jp/crid/1360283690279817984","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Reliability and importance of structural diversity of climate model ensembles"}]},{"@id":"https://cir.nii.ac.jp/crid/1360848656150384512","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Perturbed physics ensemble using the MIROC5 coupled atmosphere–ocean GCM without flux corrections: experimental design and results"}]},{"@id":"https://cir.nii.ac.jp/crid/1390282681472609920","@type":"Article","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"The role and potential of Quaternary research in constraining future climate sensitivity"},{"@language":"ja","@value":"気候感度の制約において第四紀研究の果たす役割と可能性について"},{"@language":"ja-Kana","@value":"キコウ カンド ノ セイヤク ニ オイテ ダイ4キ ケンキュウ ノ ハタス ヤクワリ ト カノウセイ ニ ツイテ"}]},{"@id":"https://cir.nii.ac.jp/crid/2051996266842852864","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"A review of progress towards understanding the transient global mean surface temperature response to radiative perturbation"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1111/j.1600-0870.2008.00345.x"},{"@type":"OPENAIRE","@value":"doi_dedup___::6dc04f9136e7a2b079164ccbe3aa6b9d"},{"@type":"CROSSREF","@value":"10.1175/2011jcli4011.1_references_DOI_5zsDeVk1A4CwjuTvmxgBQM3fcQJ"},{"@type":"CROSSREF","@value":"10.1186/s40645-016-0096-3_references_DOI_5zsDeVk1A4CwjuTvmxgBQM3fcQJ"},{"@type":"CROSSREF","@value":"10.1007/s00382-013-1733-9_references_DOI_5zsDeVk1A4CwjuTvmxgBQM3fcQJ"},{"@type":"CROSSREF","@value":"10.4116/jaqua.48.143_references_DOI_5zsDeVk1A4CwjuTvmxgBQM3fcQJ"},{"@type":"CROSSREF","@value":"10.1007/s00382-012-1441-x_references_DOI_5zsDeVk1A4CwjuTvmxgBQM3fcQJ"}]}
