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.

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. in IPCC TAR).

WMO: Update on 2023/4 Anomalies

Real Climate

We assessed the long term trend using a 20 yr loess smooth in the WMO timeseries to 2022 (which was then projected forwarded to 2024), and defined the residuals as the difference from that trend. And, as you will recall, the anomalies in 2023 specifically were not well forecast ahead of time.

The AMOC is slowing, it’s stable, it’s slowing, no, yes, …

Real Climate

While these simulations assimilate observational data, over most of the ocean surface these are basically sea surface temperatures, but surface heat loss depends also on air temperature, wind speed, humidity, radiation and cloud cover in complex ways, all of which are not accurately known.

A CERES of fortunate events…

Real Climate

That is long enough to see that there has been a noticeable trend in the Earth’s Energy Imbalance (EEI), mostly driven by a reduction in the solar radiation reflected by the planet, while the outgoing long wave radiation does not appear to contribute much. A paper last year (Goode et al., The total radiative forcing is.

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.

A glimpse into the future of radiation therapy

Physics World

That was the question posed in the closing session of last week’s ESTRO 2022 congress; and five experts stepped up to respond. Citing the ESTRO 2022 programme, she noted that many researchers are already developing adaptation and personalization for every part of the radiation treatment chain. Rogue One (to five) .
