Aerosols interact with radiation and clouds. Substantial progress made over the past 40
years in observing, understanding, and modeling these processes helped quantify the …

Current mitigation efforts and existing future commitments are inadequate to accomplish the
Paris Agreement temperature goals. In light of this, research and debate are intensifying on …

Short‑lived climate forcers (SLCFs) affect climate and are, in most cases, also air pollutants.
They include aerosols (sulphate, nitrate, ammonium, carbonaceous aerosols, mineral dust …

An overview of the Community Earth System Model Version 2 (CESM2) is provided,
including a discussion of the challenges encountered during its development and how they …

Abstract The Community Earth System Model Version 2 (CESM2) has an equilibrium climate
sensitivity (ECS) of 5.3 K. ECS is an emergent property of both climate feedbacks and …

An assessment was made of whether detectable changes in tropical cyclone (TC) activity
are identifiable in observations and whether any changes can be attributed to anthropogenic …

Anthropogenic aerosols exert a cooling influence that offsets part of the greenhouse gas
warming. Due to their short tropospheric lifetime of only several days, the aerosol forcing …

Aerosol–cloud interactions have a potentially large impact on climate but are poorly
quantified and thus contribute a substantial and long-standing uncertainty in climate …

Cloud reflectivity is sensitive to atmospheric aerosol concentrations because aerosols
provide the condensation nuclei on which water condenses. Increased aerosol …

INTRODUCTION Human-made emissions of particulate air pollution can offset part of the
warming induced by emissions of greenhouse gases, by enhancing low-level clouds that …
