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

Aviation-related aerosol emissions contribute to the formation of contrail cirrus clouds that
can alter upper tropospheric radiation and water budgets, and therefore climate. The …

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 …

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 …

There is large uncertainty in the radiative forcing induced by aircraft contrails, particularly
after they transform to cirrus. It has recently become possible to simulate contrail evolution …

The use of alternative jet fuels by commercial aviation has increased substantially in recent
years. Beside the reduction of carbon dioxide emission, the use of sustainable aviation fuels …

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 …

Air traffic has increased by about 60% between 2011 and 2019 and climate forcers from
aviation have also increased, resulting in a strong impact on climate change. It is well …

Sustainable aviation fuels can reduce contrail ice numbers and radiative forcing by contrail
cirrus. We measured apparent ice emission indices for fuels with varying aromatic content at …

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 …
