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. Thompson et al. We are using the NOAA-STAR version 3.0

Today, the New York Times reported that a recent assessment shows that the world is on track to reach pre-1980 levels of upper atmosphere ozone by roughly 2040. That is in spite of the discovery in 2018 of “rogue” use of chlorofluorocarbons, probably from factories in China.

Another clue indicating a shortcoming is if you look at the atmospheric CO 2 -concentrations over time to see how much impact the IPCC reports have had on the real policy-makers in the world (Figure below). The cause of our changing climate is the increase in atmospheric greenhouse gas concentrations that we have released into the air.

When fuels are burned to create energy in a process called combustion, black carbon along with carbon monoxide and other compounds are created because there is not enough oxygen in the atmosphere for the reaction to go to completion. Whenever there are combustion processes, of which there are many in our industrial society (e.g.,

Air emissions : Any gas emitted into the atmosphere from industrial or commercial activity. Chlorofluorocarbons (CFCs) : A group of inert chemical used in many industrial and everyday processes such as our refrigerators that are not broken down at lower atmospheric levels and rise to the upper levels, destroying ozone.

They do this by analysing the electromagnetic absorption spectra of an exoplanet’s atmosphere as it transits its sun, seeking the presence of gases such as oxygen, methane, water vapour and ozone (a proxy for oxygen). Analogous to technosignatures, these are the signs of life on alien worlds, intelligent or otherwise.

As recently as 2018, when the cost was about to break the $8bn barrier, US Congress had to vote to provide it with more funds. The JWST’s main exoplanet task will be to probe the atmospheres of these distant worlds as they pass between the telescope and their parent stars. But the telescope’s exoplanet studies will go deeper, too.
