Drop in Planetary Albedo Explains Climate Change
Timothy Birdnow
A new paper suggests that aerosols in the Earth's atmosphere cancel each-other out in the northern and southern hemispheres, but that changes in planetary albedo (cloudiness which reflects more sunlight into space) explains planetary warming.
From the article in physorg:
"The study also shows that the recent increase in Earth's energy imbalance is driven mainly by changes in reflected sunlight, rather than by changes in heat escaping to space. From 2003 to 2023, Earth gained heat at a rate of about half a watt more energy per square meter each decade, largely because the planet is absorbing more sunlight."
This was put in almost as an afterthought, but it demolishes the theory of Carbon Dioxide driven climate warming.
The article mainly discusses aerosols. As it points out, the southern hemisphere has more in the way of aerosols because of naturally occurring sources, like volcanoes and wildfires.
"The findings also highlight a potential limitation in some climate modeling studies, which focus mainly on pollution reductions in the Northern Hemisphere and may underestimate the growing influence of natural aerosol events in the Southern Hemisphere."
Again, the paper argues that aerosol cooling balances out, but that the decline in planetary albedo means more heat is coming into the climate system rather than the climate system retaining more heat from a layer of carbon dioxide.
'"Many earlier studies suggested that cleaner air might explain much of the recent increase, but our results show that aerosol changes largely cancel out between the Northern and Southern Hemispheres. That means we need to look more closely at changes in clouds and natural climate variability to understand why the planet is continuing to gain heat."
The authors of the study include Chanyoung Park and Brian Soden of the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science.'
Couple this with land use changes and we have to realize that planetary warming is being driven by more heat in the system and that heat is being retained because the forests and savannahs are giving way to blacktops and cityscapes.
In fact land use changes, the Urban Heat Island Effect, explains much of the warming we have seen.
Carbon dioxide has little to do with it. Land use changes have been largely at the center of the rise in atmospheric carbon dioxide, for instance.
Carbon dioxide driven climate change increasingly resembles the Medieval concept of how many angels can dance on the head of a pin. Over time we learn about more forcings that impact climate that are unrelated to industrial carbon dioxide emissions. At what point do we finally say "enough" and simply dismiss this as a generations-long War of the Worlds scare?

This makes very good sense to me, though I would suspect that there is going to be a lot of weeping, wailing and gnashing of teeth among the Carbon Dioxidians and other liberals who are so heavily invested in that otherwise harmless gas.

I found this linked up in a Facebook group. That group is a forum for argument and thek Gang Green was all jacked up about it. Of course they couldn't dispute the science so it was all "Exxon funded this" and other shibboleths.
