A distraction due to errors, misunderstanding and misguided Norwegian statistics

Real Climate

are used all over the world, based on calculations that quantify the effects of physical mechanisms and the way different parts of the atmosphere are connected to each other. The physics-based models describe how energy flows through the atmosphere and ocean, as well as how the forces from different air masses push against each other.

The unconventional scientist who predicted that rising carbon dioxide levels would change the climate

Physics World

The correlation had been shown in a paper by an author outside the conventional scientific community, so, for good measure, Simpson added that a non-expert could not properly appreciate how atmospheric circulation affects the absorption of radiation. Other little-known researchers, however, made essential progress too. 139 1961 ).

Solar polarization paradox resolved at last

Physics World

The current polarization puzzle originated in 1996, when astrophysicists Jan Stenflo of ETH Zurich in Switzerland and Christoph Keller (then at the US National Solar Observatory in Arizona) used an instrument called ZIMPOL (Zurich Imaging Polarimeter) to study solar radiation at a wavelength of around 589nm.

A deep dive into the IPCC’s updated carbon budget numbers

Real Climate

And since the first IPCC estimates published in 2013, we have learned a lot and have gotten much better at estimating remaining carbon budgets. IPCC reported carbon budgets for the first time in 2013. in 2018, but they represent a significant update since AR5 in 2013. In the 2018 IPCC Special Report on Global Warming of 1.5°C

Getting physical with the climate crisis

Physics World

As air sunk through the atmosphere, it got squeezed and heated. In his book Making the Modern World , the Czech-Canadian energy researcher Vaclav Smil estimates that China used more cement between 2011 and 2013 than the US did in the entire 20th century.

AR6 of the best

Don’t mention the hiatus: Readers will probably remember the prominence of the ‘hiatus’ in the discussions around the AR5 report (written in 2013) (see here , here , or here ). and other things worth noting – for instance, the much better and more direct graphics that they have clearly worked on a lot.

Cosmic challenge: protecting supercomputers from an extraterrestrial threat

Physics World

In 2013 a gamer by the name “DOTA_Teabag” was playing Nintendo’s Super Mario 64 and suddenly encountered an “impossible” glitch – Mario was teleported into the air, saving crucial time and providing an advantage in the game. The culprit, again, was most likely cosmic radiation.
