Aircraft-produced contrail cirrus clouds contribute to anthropogenic climate change.
Observational data sets and modelling approaches have become available that clarify …

Global aviation operations contribute to anthropogenic climate change via a complex set of
processes that lead to a net surface warming. Of importance are aviation emissions of …

Contrail cirrus account for the major share of aviation's climate impact. Yet, the links between
jet fuel composition, contrail microphysics and climate impact remain unresolved. Here we …

Around 5% of anthropogenic radiative forcing (RF) is attributed to aviation CO 2 and non-CO
2 impacts. This paper quantifies aviation emissions and contrail climate forcing in the North …

Powering aircraft by sustainable aviation fuels (SAFs) is a pathway to reduce the climate
impact of aviation by lowering aviation lifecycle CO 2 emissions and by reducing ice crystal …

The climate forcing of contrails and induced-cirrus cloudiness is thought to be comparable to
the cumulative impacts of aviation CO2 emissions. This paper estimates the impact of …

A growing body of research has highlighted the major contribution of aviation non-CO2
emissions and effects to anthropogenic climate change. Regulation of these emissions, for …

The current best-estimate of the global annual mean radiative forcing (RF) attributable to
contrail cirrus is thought to be 3 times larger than the RF from aviation's cumulative CO2 …

The strong reduction of air traffic during the COVID-19 pandemic provides a unique test case
for the relationship between air traffic density, contrails, and their radiative forcing of climate …

Globally, emissions from aviation affect Earth's climate via complex processes. Contrail
cirrus and carbon dioxide emissions are the largest factors contributing to aviation's radiative …
