Open AccessAssessing the size and uncertainty of remaining carbon budgets
The remaining carbon budget (RCB), the net amount of CO2 humans can still emit without exceeding a chosen global warming limit, is often used to evaluate political action against the goals of the Paris Agreement....

Validation of an Enhanced Telehealth Platform for Toddlers at Increased Likelihood for a Diagnosis of Autism Spectrum Disorder (ASD)
Use of telehealth assessments for toddlers at increased likelihood of autism spectrum disorder (ASD) began prior to the global COVID-19 pandemic; however, the value of telehealth assessments as an alternative ...

Open AccessSurface warming and wetting due to methane’s long-wave radiative effects muted by short-wave absorption
Although greenhouse gases absorb primarily long-wave radiation, they also absorb short-wave radiation. Recent studies have highlighted the importance of methane short-wave absorption, which enhances its strato...

Article
Large uncertainty in future warming due to aerosol forcing
Despite a concerted research effort and extensive observational record, uncertainty in climate sensitivity and aerosol forcing, the two largest contributions to future warming uncertainty, remains large. Here ...

Open AccessThe Etruscans: Setting New Agendas
The Etruscans, who dominated central Italy for much of the first half of the first millennium BC, are ripe for new analysis: the quantity of data for their culture is now substantial, wide ranging, and qualifi...

Article
Open AccessInstitutional decarbonization scenarios evaluated against the Paris Agreement 1.5 °C goal
Scientifically rigorous guidance to policy makers on mitigation options for meeting the Paris Agreement long-term temperature goal requires an evaluation of long-term global-warming implications of greenhouse ...

Imminent loss of climate space for permafrost peatlands in Europe and Western Siberia
Human-induced climate warming by 2100 is expected to thaw large expanses of northern permafrost peatlands. However, the spatio-temporal dynamics of permafrost peatland thaw remain uncertain due to complex perm...

Open AccessMotivations, barriers, and professional engagement: a multisite qualitative study of internal medicine faculty’s experiences learning and teaching point-of-care ultrasound
Point-of-care ultrasound (POCUS) graduate medical education is expanding across many specialties, but a lack of trained faculty is a common barrier. Even well-designed faculty development programs struggle wit...

Open AccessImproving hospital-based point-of-care ultrasound cleaning practices using targeted interventions: a pre–post study
Point-of-care ultrasound (POCUS) devices are becoming more widely used in healthcare and have the potential to act as fomites. The objective of this project was to study the thoroughness of cleaning of POCUS m...

Projected land ice contributions to twenty-first-century sea level rise
The land ice contribution to global mean sea level rise has not yet been predicted1 using ice sheet and glacier models for the latest set of socio-economic scenarios, nor using coordinated exploration of uncertai...

Article
Stringent mitigation substantially reduces risk of unprecedented near-term warming rates
Following the Paris Agreement, many countries are enacting targets to achieve net-zero GHG emissions. Stringent mitigation will have clear societal benefits in the second half of this century by limiting peak ...

Article
Open AccessAn integrated approach to quantifying uncertainties in the remaining carbon budget
The remaining carbon budget quantifies the future CO2 emissions to limit global warming below a desired level. Carbon budgets are subject to uncertainty in the Transient Climate Response to Cumulative CO2 Emissio...

Article
Open AccessThe effect of rapid adjustments to halocarbons and N2O on radiative forcing
Rapid adjustments occur after initial perturbation of an external climate driver (e.g., CO2) and involve changes in, e.g. atmospheric temperature, water vapour and clouds, independent of sea surface temperature c...

Current and future global climate impacts resulting from COVID-19
The global response to the COVID-19 pandemic has led to a sudden reduction of both GHG emissions and air pollutants. Here, using national mobility data, we estimate global emission reductions for ten species d...

Grain legumes in crop rotations under low and variable rainfall: are observed short-term N benefits sustainable?
Increased grain yields are frequently obtained when a cereal follows a grain legume in sequence compared with a cereal-cereal rotation. The biotic (disease break) and abiotic (N supply) components of the obser...
