Soil carbon sequestration in global working lands as a gateway for negative emission technologies.

The ongoing climate crisis merits an urgent need to devise management approaches and new technologies to reduce atmospheric greenhouse gas concentrations (GHG) in the near term. However, each year that GHG concentrations continue to rise, pressure mounts to develop and deploy atmospheric CO2 removal pathways as a complement to, and not replacement for, emissions reductions. Soil carbon sequestration (SCS) practices in working lands provide a low-tech and cost-effective means for removing CO2 from the atmosphere while also delivering co-benefits to people and ecosystems. Our model estimates suggest that, assuming additive effects, the technical potential of combined SCS practices can provide 30%-70% of the carbon removal required by the Paris Climate Agreement if applied to 25%-50% of the available global land area, respectively. Atmospheric CO2 drawdown via SCS has the potential to last decades to centuries, although more research is needed to determine the long-term viability at scale and the durability of the carbon stored. Regardless of these research needs, we argue that SCS can at least serve as a bridging technology, reducing atmospheric CO2 in the short term while energy and transportation systems adapt to a low-C economy. Soil C sequestration in working lands holds promise as a climate change mitigation tool, but the current rate of implementation remains too slow to make significant progress toward global emissions goals by 2050. Outreach and education, methodology development for C offset registries, improved access to materials and supplies, and improved research networks are needed to accelerate the rate of SCS practice implementation. Herein, we present an argument for the immediate adoption of SCS practices in working lands and recommendations for improved implementation.

Use of a hooked cutting device compared with scissors for the emergency exposure of critically ill and injured patients.

INTRODUCTION: The initial assessment of critical patients includes prompt identification of life-threatening conditions. Any device or technique that can aid in this process may ultimately save lives. This study examined whether clothing could be removed faster with the use of a hooked cutting device as compared with the commonly-used heavy-duty, blunt-tipped, serrated scissors. METHODS: This study took place in an urban academic emergency department of a Level-1 trauma center. Human patient simulator mannequins were clothed in identical shirts and pants. The time required for clinical personnel to expose the patient using each device was measured. Each of the 50 participants was queried regarding their tactile comfort using each device. RESULTS: The mean time for shirt removal using scissors was 83 seconds (SD = 55 seconds; 95% CI, 68-99). The mean time for shirt removal using the hook device was 28 seconds (SD = 21 seconds; 95% CI, 22-34). The mean time for pants removal using scissors was 69 seconds (SD = 40 seconds; 95% CI, 56-73). The mean time for pants removal using the hook device was 19 seconds (SD=15 seconds; 95% CI, 15-23). CONCLUSIONS: The hooked device was 69% faster at removing clothing than traditionally-used scissors. Though simple in concept, these implications can be life saving, particularly in conditions of uncontrolled, life-threatening external hemorrhage.
