Butnar, Isabela, et al. (2020): The Role of Bioenergy for Global Deep Decarbonization: CO 2 Removal or Low‐carbon Energy?

Butnar, Isabela, Oliver Broad, Baltazar Solano Rodriguez, and Paul E. Dodds (2020): The Role of Bioenergy for Global Deep Decarbonization: CO2 Removal or Low‐carbon Energy? GCB Bioenergy, January. https://doi.org/10.1111/gcbb.12666.

"‌We use a global integrated assessment model, TIAM‐UCL, to investigate the role of bioenergy within the global energy system when direct air capture and afforestation are available as cost‐competitive alternatives to BECCS. We find that the presence of other CO2 removal technologies does not reduce the pressure on biomass resources but changes the use of bioenergy for climate mitigation."

Hemes, Kyle S.; et al. (2020): Wildfire‐smoke aerosols lead to increased light use efficiency among agricultural and restored wetland land uses in California's Central Valley

Hemes, Kyle S.; Verfaillie, Joseph; Baldocchi, Dennis D. (2020): Wildfire‐smoke aerosols lead to increased light use efficiency among agricultural and restored wetland land uses in California's Central Valley. In J. Geophys. Res. Biogeosci. DOI: 10.1029/2019JG005380.

"In this work, we leverage a meso‐network of eddy covariance measurement sites across a unique array of managed and restored C3 and C4 canopy types to understand how recent wildfire smoke affected ecosystem productivity during the summer of 2018, an especially smoky year in the agriculturally productive Central Valley."

Call for Abstracts: SEG | AGU Advances in Distributed Sensing for Geophysics Workshop

Deadline: 02. March 2020

"Geophysical data acquisition is currently undergoing a revolution driven by new advances in distributed sensing approaches based on fiber optics, inexpensive nodal systems, and ubiquitous sensors. This workshop seeks to bring together researchers from industry, academia, and the public sector involved in exploiting these recent sensing advances with the broader geoscience community to explore both the underlying technologies as well as new domains for distributed sensor deployment."

Carbon Brief: Guest post: The irreversible emissions of a permafrost ‘tipping point’

"Abrupt permafrost thaw is one of the most frequently discussed “tipping points” that could be crossed in a warming world. However, research suggests that, while this thawing is already underway, it can be slowed with climate change mitigation."

MSN: Could putting pebbles on beaches help solve climate change?

"Eric Matzner, who co-founded the nonprofit Project Vesta this year, intends to mine tons of a soft, crumbly green volcanic stone called olivine, grind it into pebbles and spread it on shorelines, coves and beaches, where the wave action will weather it down like a river sculpts gravel."

Bódai, Tamás; et al. (2020): Can we use linear response theory to assess geoengineering strategies?

Bódai, Tamás; Lucarini, Valerio; Lunkeit, Frank (2020): Can we use linear response theory to assess geoengineering strategies? In Chaos 30 (2), p. 23124. DOI: 10.1063/1.5122255.

"First, our objective (O1) is to assess only the best possible geoengineering scenario by looking for a suitable modulation of solar forcing that can cancel out or otherwise modulate a climate change signal that would result from a rise in carbon dioxide concentration [CO22] alone. [...] Second, to be able to utilize LRT to quantify side-effects, the response with respect to uncontrolled observables, such as regional averages Ts⟨Ts⟩, must be approximately linear."
