Study finds GHG methane offsets its warming ~30% and precipitation increase ~60% by short-wave absorption

Green Car Congress

A new study by researchers from the University of California, Riverside and colleagues in the US and Europe has now found that methane short-wave absorption counteracts ~30% of the surface warming associated with its long-wave radiative effects. However, greenhouse gases also absorb short-wave radiation incoming from the sun.

PNNL-led international study finds ultrafine aerosols have outsize impact on storm clouds, precipitation

Green Car Congress

Aerosol impacts on cloud processes via this pathway are known as aerosol indirect effects, referred to as aerosol-cloud interaction in the most recent Intergovernmental Panel on Climate Change report. Aerosol impacts are a key uncertainty in understanding the current and future climate as well as extreme weather.
