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 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.

A distraction due to errors, misunderstanding and misguided Norwegian statistics

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 Rise and Fall of the “Atlantic Multidecadal Oscillation”

Real Climate

About five years later, analysis of an extended simulation of yet another climate model–the coupled ocean-atmosphere model run by the Hadley Centre within the UK Meteorological Office, yielded evidence for a similar oscillation, albeit with a longer (roughly 100 year) period, and a more global signature (Knight et al.,

Invading black hole or neutron star caused star to explode, say astronomers

Physics World

Astronomers have speculated that if the compact object is close to its surviving companion star, it can spiral into the star’s atmosphere, eventually sinking to the companion’s core where it disrupts the star, causing it to go supernova prematurely. This means that it appeared sometime between 2005 and 2017. solar masses per year.

The enduring mystery of the solar corona

Physics World

Many space missions since SKYLAB have extended our measurements of the corona beyond EUV and X-ray wavelengths, yielding details of the even-higher-energy gamma radiation it emits. Viewed in this way, the problem was “solved” by the Scandinavian physicists Boris Gudiksen and Åke Nordlund in 2005, who used just 3.375 million cells.

Oil Refineries: A Deadly Industry

Union of Concerned Scientists

It not only traps heat in the atmosphere, contributing to global warming, but the warmer temperature resulting from global warming leads to an increase in ground-level ozone, since ozone is produced indirectly from precursors like NOx and VOCs in the presence of sunlight. which is formed in the atmosphere from precursor gases such as NOx.
