Why the World Needs a New UN Study on the Effects of Nuclear War

Union of Concerned Scientists

New scientific information has yielded insights, including updates to our understanding of, and ability to model, the atmosphere, and the studies of the long-term effects of radiation on affected populations have yielded new information. New studies are being published and commissioned and research gaps are being identified.

How Do ‘Future Climate Scenarios’ Shape Climate Science and Inform Policy? 

Union of Concerned Scientists

Four RCP scenarios describe different levels of radiative forcing in the atmosphere by 2100. Radiative forcing is the change in energy balance in the Earths atmosphere due to heat trapping emissions. Studies show that high-emission scenarios like SSP5-8.5

FRESH, October 4, 2022: Carbon Dioxide Storage and Transport Emerges as Political Flashpoint

Circle of Blue

Why it matters: The recent Inflation Reduction Act expands the tax credit for capturing carbon dioxide that would otherwise be released into the atmosphere. The post FRESH, October 4, 2022: Carbon Dioxide Storage and Transport Emerges as Political Flashpoint appeared first on Circle of Blue.

Delayed harm and the politics of climate change, reconsidered

Legal Planet

What are the political implications of the fact that climate change will continue after emissions cease, or even potentially grow worse? First, after carbon dioxide emissions cease, atmospheric carbon dioxide levels begin to decrease, as they are absorbed by natural processes and sinks in the oceans and on land. degrees Celsius.

New Satellite Will See Water’s Big Picture

Circle of Blue

Instruments installed on the International Space Station are refining weather forecasts by measuring water vapor in the atmosphere and water held in clouds. Incorporating satellite data, the program estimates water that plants “breathe” into the atmosphere and water that evaporates from farm fields.

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. After that, the sulfur is gone but the CO 2 is still there and heating.)

Why a Bird in the Hand is Worth Two in the Bush — Especially When the Issue is Climate Change

Legal Planet

Forever is only a bit of an overstatement: NASA says CO2 stays in the atmosphere three hundred to a thousand years. If we wait to get the stronger policy, we’re accumulating emissions that will stay in the atmosphere for centuries — in other words, doing permanent damage to the climate.
