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

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.

Now however, the updates to the historical warming , the use of four datasets instead of one, and of course, the series of record breaking years subsequently (2014, 2015, 2016/2020), the issue of variability in decadal trends is no longer so salient. 1981) which can be seen here.

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. Gradually, the compact object came to be within the star’s atmosphere. Compact object.

Back in Black: Creating positive changes by focusing on a short-lived pollutant

HumanNature

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.,

Using Clouds to Fight Climate Change

HumanNature

Student in the Department of Atmospheric Science at Colorado State University Most people remember the water cycle they learned in school: water evaporates from lakes, rivers, and the ocean, air carrying this moisture rises, cools, condenses, and forms clouds, and these clouds precipitate water back down to the surface.
