Orbital pacing and secular evolution of the Early Jurassic carbon cycle

Publication ID: pub.1124798751

Publication date: 10/02/2020

Keywords: Astrochronology; Early Jurassic; Global; Global Carbon Cycle; δ13CTOC Record

Global perturbations to the Early Jurassic environment (∼201 to ∼174 Ma), notably during the Triassic-Jurassic transition and Toarcian Oceanic Anoxic Event, are well studied and largely associated with volcanogenic greenhouse gas emissions released by large igneous provinces. The long-term secular evolution, timing, and pacing of changes in the Early Jurassic carbon cycle that provide context […]

Mitigation of ozone damage to the world’s land ecosystems by source sector

Publication ID: pub.1124340343

Publication date: 27/01/2020

Keywords: Air Quality; Anthropogenic; Atmosphere; Climate; Earth System Model; Emission Abatement; Global; Land Ecosystems; Mitigation; Ozone Damage; Ozone Precursor; Source Sectors; Vegetation

Surface ozone damages photosynthesis and reduces the ability of land ecosystems to assimilate carbon from the atmosphere thereby further increasing global warming1,2. Ozone is not emitted directly but formed in the atmosphere during complex chemical reactions of precursors, carbon monoxide, methane, non-methane volatile organic compounds and nitrogen oxides, in sunlight. These ozone precursors are emitted […]

Natural drivers of multidecadal Arctic sea ice variability over the last millennium

Publication ID: pub.1124190242

Publication date: 20/01/2020

Keywords: Anthropogenic; Arctic; Arctic Sea Ice; Atlantic; Atlantic Meridional Overturning Circulation (AMOC); Climate; Climate Model; Drivers; Feedbacks; Greenland-Iceland-Norway Seas (GINS); Last Millenium; Multidecadal; Natural; Paleoclimate Modelling Intercomparison Project (PMIP); Variability

The climate varies due to human activity, natural climate cycles, and natural events external to the climate system. Understanding the different roles played by these drivers of variability is fundamental to predicting near-term climate change and changing extremes, and to attributing observed change to anthropogenic or natural factors. Natural drivers such as large explosive volcanic […]

Debate: The pressing need for research and services for gender desisters/detransitioners

Publication ID: pub.1124104718

Publication date: 15/01/2020

Keywords: Gender Dysphoria; Gender Identity; Therapy

The number of people presenting at gender clinics is increasing worldwide. Many people undergo a gender transition with subsequent improved psychological well-being (Paediatrics, 2014, 134, 696). However, some people choose to stop this journey, ‘desisters’, or to reverse their transition, ‘detransitioners’. It has been suggested that some professionals and activists are reluctant to acknowledge the […]

A Data-Driven Social Network Intervention for Improving Organ Donation Awareness Among Minorities: Analysis and Optimization of a Cross-Sectional Study

Publication ID: pub.1122536483

Publication date: 14/01/2020

Keywords: Cross-Sectional Studies; Humans; Minority Groups; Social Networking; Tissue and Organ Procurement; US

BACKGROUND: Increasing the number of organ donors may enhance organ transplantation, and past health interventions have shown the potential to generate both large-scale and sustainable changes, particularly among minorities. OBJECTIVE: This study aimed to propose a conceptual data-driven framework that tracks digital markers of public organ donation awareness using Twitter and delivers an optimized social […]

Shifts in national land use and food production in Great Britain after a climate tipping point

Publication ID: pub.1124047582

Publication date: 13/01/2020

Keywords: Agricultural Output; Atlantic Meriodional Overturning Circulation (AMOS); Climate Change; Climate Tipping Points; Food Production; Great Britain; Land Use; Technological Adaptations

Climate change is expected to impact agricultural land use. Steadily accumulating changes in temperature and water availability can alter the relative profitability of different farming activities and promote land-use changes. There is also potential for high-impact ‘climate tipping points’, where abrupt, nonlinear change in climate occurs, such as the potential collapse of the Atlantic Meridional […]
