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.

The CO2 problem in six easy steps (2022 Update)

Real Climate

The fact that there is a natural greenhouse effect (that the atmosphere restricts the passage of infra-red (IR) radiation from the Earth’s surface to space) is easily deducible from; i) the mean temperature of the surface (around 15ºC) and, ii) knowing that the planet is normally close to radiative equilibrium.

since the 1850-1900 baseline is very clearly associated with the increases in greenhouse gases, slightly (and decreasingly) modulated by the changes in atmospheric pollution.

The CERES estimates of the top-of-atmosphere radiative fluxes are available from 2001 to the present. 2021) also reported on a two decade estimate of Earthshine measurements which appear to confirm a small decrease in albedo (and decrease in reflected short wave (SW) radiation). A paper last year (Goode et al., It’s unlikely(?)

Clauser-ology: Cloudy with a chance of meatballs

Real Climate

Some of you will have heard of John Clauser because he was an awardee of the 2022 Nobel Prize in Physics for his role in the experimental verification of quantum entanglement. He, however, goes seriously off the rails when he estimates the impact of clouds on the radiation budget. John Clauser’s theory of climate explained.

CMIP6: Not-so-sudden stratospheric cooling

Real Climate

So SSU me Like MSU trends, these records reflected a weighted average of atmospheric temperatures, and the three SSU channels progressively weight higher levels in the stratosphere, roughly centered on 30km, 40km and 45km above the surface but with quite a bit of overlap. 128, 2022. The effect is larger the further up you go.

Upcoming Developments in International Governance of Marine Carbon Dioxide Removal

Law Columbia

They focused specifically on two marine CDR approaches—ocean alkalinity enhancement and biomass cultivation for carbon removal (including seaweed cultivation and sinking) —and two solar radiation management techniques—marine cloud brightening and surface albedo enhancement. Solar radiation management is distinct from CDR.
