Nature- Rohatyn et al. (2023): Large variations in afforestation-related climate cooling and warming effects across short distances

Shani Rohatyn, Eyal Rotenberg, Fyodor Tatarinov, Yohay Carmel, Dan Yakir IN: Commun Earth Environ 4, 18; https://doi.org/10.1038/s43247-023-00678-9

The authors show in a four-year study that the biogeochemical vs. biogeophysical balance in paired forested and non-forested ecosystems across short distances (approximately 200 Km) and steep aridity gradient (aridity index 0.64 to 0.18) can change dramatically. The required time for the forestation cooling effects via carbon sequestration, to surpass warming effects associated with the forests’ reduced albedo and suppressed longwave radiation, decreased from 213 years in the driest sites to 73 years in the intermediate and 43 years in the wettest sites.

Powis et al. (2023): Quantifying global carbon dioxide removal deployment

Carter M Powis, Stephen M Smith, Jan C Minx, Thomas Gasser IN: Environmental Research Letters, DOI 10.1088/1748-9326/acb450

It is not known how much CDR is currently deployed at a global scale, nor how that compares to mitigation scenario estimates. Here, the authors address this problem by developing an estimate of global current CDR activity. They draw on national greenhouse gas inventory data combined with CDR registries and commercial databases to estimate that global anthropogenic activity presently generates ~1985 MtCO2yr-1 of atmospheric removals. To conclude the authors discuss uncertainties related to their estimates, and suggest priorities for the future collection and management of CDR data, particularly related to the role of the land sink in generating CDR.

COMPASS Communicating Science Workshops for Ocean Carbon Dioxide Removal Scientists and Researchers

Applications close: January 30

This series of COMPASS science communication workshops will help scientists turn their research on ocean carbon dioxide removal into compelling messages and prepare for media and policy communication and engagement.

The dates of the three workshops are as follows: 

  • Developing your Message (Virtual) March 15-16, 1:30-4:30pm ET (Please note that participation in this workshop is required to attend either of the in-person workshops)
  • Communicating with Journalists in Atlanta, GA on April 3 
  • Communicating with Policymakers in Washington, DC on June 5

White Paper: How Direct Air Capture Succeeds

Courtni Holness, Shuchi Talati, Eliot Reali, Tracy Yu on carbon180.org, 20 pp.

Direct air capture (DAC) hubs will soon begin to come online and set the US on a course to remove millions of tons of CO₂ — but the field currently lacks clear, shared markers of success. This white paper offers an original framework to assess progress and ensure these hubs empower innovators and communities.

Günther offen für CO2-Speicherung im Meer: Starke Reaktionen

dpa, zeit online, 20. Januar 2023, 13:19 Uhr

„Die Diskussionen über eine unterirdische Speicherung von Kohlendioxid gewinnen in Schleswig-Holstein weiter an Fahrt. Nachdem sich nun auch Ministerpräsident Daniel Günther (CDU) offen für eine Nutzung dieser Technologie gezeigt hat, erntete er dafür zum Teil heftige Kritik, weil der Landtag noch im vorigen Jahr einstimmig dagegen war. Die Debatte offenbart auch Differenzen in der schwarz-grünen Koalition.“
