Since the Industrial Revolution, addition of anthropogenic CO_2 to the atmosphere has caused a significant increase in atmospheric CO_2,accompanied by a decrease in δ^<13>C of atmospheric CO_2. The relationship between them shows that the δ^<13>C value of CO_2 which remained in the atmosphere is significantly larger than -25‰ of that originated from coal burning and deforestation at mid-latitudes. So, we consider that the δ^<13>C value of CO_2 uptaken from the atmosphere should be small. Then we calculated the δ^<13>C value of CO_2 which remained in the atmosphere, obtaining a result of about -13‰. We considered that this fact would be useful as a new constraint on the anthropogenic CO_2 budget. On the other hand, IPCC 1994 reported the revised budget of anthropogenic CO_2 and emphasized that the problem of the missing sink of CO_2 was solved. So, as this budget is determined for carbon as an element (that is, ^<12>C), we examined the budget reported by IPCC for ^<13>C. In the anthropogenic CO_2 budget in IPCC 1994,for the sources the δ^<13>C values of 5.5Gt/yr of carbon which originates from emissions from fossil fuel burning, and 1.6Gt/yr from emission from deforestation in the tropical region may be given as -27‰ and -30‰, respectively. For the sinks, the δ^<13>C values of 3.2Gt/yr of carbon which remains in the atmosphere, 0.5Gt/yr in northern hemisphere forest regrowth and 1.4Gt/yr in additional terrestrial sinks may be given as -13‰, -25‰ and -30&acd;-25‰, respectively. Therefore, as the result of calculation, δ^<13>C of 2.0Gt/yr of carbon which is uptaken in the ocean became very small. -54&acd;-46‰. This result cannot be explained by the observed fractionations for CO_2 exchange between the atmosphere and the ocean, photosynthesis and formation of carbonate. This indicates that the anthropogenic CO_2 budget reported by IPCC 1994 still has some problem.","subitem_description_type":"Other"}]},"item_1_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.15094/00004015","subitem_identifier_reg_type":"JaLC"}]},"item_1_publisher_22":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"National Institute of Polar Research"}]},"item_1_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AA10756213","subitem_source_identifier_type":"NCID"}]},"item_1_text_10":{"attribute_name":"著者所属(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute for Hydrospheric-Atmospheric Sciences, Nagoya University"},{"subitem_text_language":"en","subitem_text_value":"Institute for Hydrospheric-Atmospheric Sciences, Nagoya University"}]},"item_1_text_3":{"attribute_name":"記事種別(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"ABSTRACT"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"1997-11-01"}],"displaytype":"detail","filename":"KJ00001014978.pdf","filesize":[{"value":"81.5 kB"}],"format":"application/pdf","licensetype":"license_6","mimetype":"application/pdf","url":{"label":"KJ00001014978","url":"https://nipr.repo.nii.ac.jp/record/4015/files/KJ00001014978.pdf"},"version_id":"3cd6ce8a-0fd5-443d-a104-2f6f7a74af46"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"NEW CONSTRAINT ON ESTIMATION OF THE ANTHROPOGENIC CO_2 BUDGET : RELATIONSHIP BETWEEN CONCENTRATION AND δ^<13>C OF ATMOSPHERIC CO_2 DETERMINED FROM ICE CORE ANALYSIS","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"NEW CONSTRAINT ON ESTIMATION OF THE ANTHROPOGENIC CO_2 BUDGET : RELATIONSHIP BETWEEN CONCENTRATION AND δ^<13>C OF ATMOSPHERIC CO_2 DETERMINED FROM ICE CORE ANALYSIS"}]},"item_type_id":"1","owner":"4","path":["535"],"pubdate":{"attribute_name":"公開日","attribute_value":"1997-11-01"},"publish_date":"1997-11-01","publish_status":"0","recid":"4015","relation_version_is_last":true,"title":["NEW CONSTRAINT ON ESTIMATION OF THE ANTHROPOGENIC CO_2 BUDGET : RELATIONSHIP BETWEEN CONCENTRATION AND δ^<13>C OF ATMOSPHERIC CO_2 DETERMINED FROM ICE CORE ANALYSIS"],"weko_creator_id":"4","weko_shared_id":4},"updated":"2023-07-25T12:25:01.298508+00:00"}
