Circle of Blue

The rains were the result of a weather phenomenon known as an “atmospheric river,” a narrow column that transports water vapor from the tropics to the poles. Atmospheric rivers are projected to intensify as the climate continues to warm. Atmospheric rivers are not uncommon in the region.

A Dangerous Disruption

Legal Planet

The “for one year” part is crucial: stratospheric aerosols stay in the atmosphere roughly a year, so one gram offsets the heating effect of one ton only for the first year after the ton is emitted. SAI can offset the effects of greenhouse gases on global-average temperature, but not their total climatic and environmental effects.

The Great-Great-Grandmother of Climate Science

Legal Planet

She observed that “an atmosphere of that gas would give to our earth a high temperature; and if, as some suppose, at one period of its history, the air had mixed with it a larger proportion than at present, an increased temperature from its own action, as well as from increased weight, must have necessarily resulted.”

The Fuss about Methane

Legal Planet

OK, on to methane in the environment: The headline here – whether you’re talking about atmospheric concentrations, climate impacts, or emissions – is that there is a lot less methane than CO 2 , but it’s a more potent climate heater and it’s increasing faster. Atmospheric concentrations. Climate impact. W/m 2 from elevated CO 2.

Management approved her shift in emphasis, hoping that she would prove that aerosols in the atmosphere (including those from auto exhaust) would completely offset the greenhouse gas effect. She met a visiting physicist from Princeton on her very first week on the job. He talked her into studying climate change.
