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. But why is the stratosphere increasingly chill?

Step 1: There is a natural greenhouse effect. This means that there is an upward surface flux of IR around (~398 W/m 2 ), while the outward flux at the top of the atmosphere (TOA) is roughly equivalent to the net solar radiation absorbed (~240 W/m 2 ). Step 2: Trace gases contribute to the natural greenhouse effect.

JUNE 5, 2022

With proposed federal regulation of greenhouse gas emissions by the Securities and Exchange Commission requiring GHG disclosure and new state statutes, including a new Maryland law that requires not only disclosure, but also a mandated reduction in GHG emissions, a greater appreciation of the subject of GHG appears in order.

So this is an attempt to put all of that in context and provide a hopefully comprehensive guide to how, when, and why to properly compare the two greenhouse gases. Before we go any further though, we need to understand that the effective perturbation time for CO 2 and CH 4 in the atmosphere are very different. Historical comparisons.

Some in the industry see the warming as an opportunity, as passages through the Arctic open for longer periods, even going so far as to claim there will be lower overall greenhouse gas (GHG) emissions from the shorter voyages.

Also missing is any realization that clouds also contribute to the greenhouse effect (roughly 25% of the total) and so whether cloud changes warm or cool depends very much on where the clouds are (high clouds have a very different effect than low clouds for instance).

For example, the ongoing debate over the impact of certain pesticides in agriculture , greenhouse gas emissions are often a battle between the science and industry's attempts to muddy the science and government lobbying to roll back legislation (2). Air emissions : Any gas emitted into the atmosphere from industrial or commercial activity.
