SOCCR2 and NCA4 Released

SOCCR2 Front Cover

SOCCR2, a Sustained Assessment report of the U.S. Global Change Research Program was released on November 23, 2018.

SOCCR2 Report-in-Brief  

(Use #SOCCR2 #NCA4 in social media communications please.)

 

The Second State of the Carbon Cycle Report (SOCCR2) was released by the U.S. Global Change Research Program (USGCRP) on Friday, November 23, 2018.

With over 200 contributing experts, this interagency Highly Influential Scientific Assessment was led by the Carbon Cycle Interagency Working Group (CCIWG) and U.S. Carbon Cycle Science Program under USGCRP auspices.

Incorporating 19 chapters distributed across four interconnected sections  (I. Synthesis, II. Human Dimensions of the Carbon Cycle, III. State of Air, Land, and Water, IV. Consequences and Ways Forward), SOCCR2 assesses the last decade of cross-sectoral carbon cycle advances across the U.S., Canada and Mexico, in the global context.

Individual chapter PDF links are provided below and can also be downloaded via https://carbon2018.globalchange.gov.

The 36-page SOCCR2 Report-in-Brief includes the Executive Summary and a plain language overview.

 

This decadal interagency U.S. Government report involved diverse experts from multiple institutions over 3 years, producing over 6 drafts that collectively underwent over 6 rounds of formal reviews.
 
Congratulations to the entire SOCCR2 team, whose commitment and hard work has been truly inspiring throughout this process. 
 

The 4th U.S. National Climate Assessment (NCA4) was also released simultaneously via

 

 
Please utilize, disseminate and amplify the SOCCR2 findings and information from https://carbon2018.globalchange.gov using #SOCCR2 #NCA4. 
 

Thanks to all of carbon cycle science colleagues and friends who helped in many ways, including in producing and sharing the science, tools and and knowledge assessed in #SOCCR2.
