I was describing what is causing temperature heating in the parts of the atmosphere where we live and that impacts us and that is not due to solar maximum output and that we don’t see upper atmospheric heating.
Almost all of the additional output in the suns electromagnetic spectrum during solar maximum is in the ultraviolet and X-ray frequencies of the spectrum.
X-rays are almost all blocked by the magnetosphere and hardly any reach earth. It’s why space flight is dangerous. No magnetosphere protection to X-rays away from earth.
The additional ultraviolet gets mostly blocked by the ozone in the upper atmosphere. By blocked I mean that it breaks down ozone into O2 and O. By not pumping HFC’s into the upper atmosphere, the O2 and O recombine into Ozone which is O3.
Also the particles emitted in solar flares are mostly blocked by the magnetosphere. Again a concern with space flight outside of earths magnetosphere.
The bits that make it through increase the atmospheric temperature by very little as others have said of about 0.1 degrees.
The infrared light which is about 51% of the suns electromagnetic spectrum gets absorbed by clouds and the particles and compounds we have pumped into the lower atmosphere from burning fossil fuels.
By absorbed I mean that there are complex breakdowns of compounds, radiation emitted which is heat and recombination. Too in-depth for this discussion but the end result is that the lower atmosphere heats up.
In summary, the increase of infrared absorption at lower atmospheric levels is causing heating at this level because of the additional infrared absorbing compounds we have pumped into the lower atmosphere. The upper atmosphere has cooled to conserve energy of the atmospheric system.
I should add to the discussion climate sensitivity. That’s the increase in lower atmospheric temperatures if we double the output of compounds that heat up the atmosphere. Models show an approx heating of 3 degrees.
Most models base this heating level on core samples taken over the last 100,000 years. There is little input in these models of clouds.
Models that factor the effect of clouds and decrease the input effect from core samples (that obviously do not take into account clouds during time period of core samples), on average have a 5.5 degree increase for climate sensitivity.
These cloud based climate models have been more accurate in predicting weather events. This scares me.
IPCC and many climate scientists effectively support which climate models are promoted as most accurate.
Unless my memory is mistaken, you have an intimate knowledge why some science endeavors are promoted more than others.
The effects on climate change due to sensitivity can’t be proven at this time. If IPCC is wrong in its views, who cares? They would of made their names and money and have retired by the late 21st century.
You do know that scientists have drilled into glaciers in the northern hemisphere and Antarctica and retrieved and tested core samples to depths that cover hundreds of thousands of years?
It’s similar to drilling into hundreds of years old trees and determining environmental details of the time of each tree ring.
What you posted was that core samples have been taken for 100,000 years.
Cores samples can help create models, and dating is accurate enough to a matter of years in 10,000. But the composition of the core give just an estimate of climate 100,000 years ago, as the sample is relatively very small. Core sampling can also change the composition of core in drilling out the sample as well.
In oil exploration, where my Company has done a great deal of scientific work, mining engineers take cores over a range of sites to get a better picture of the geology. Research work in glaciers in Antartica goes down to about 4000 metres but due to many factors does not do the same volume of bores. It is a work in progress, difficult and expensive.
Is the changes to polar Jet Streams the major driver to this flooding? If so what is the underlying causes of the Jet Streams going “wavey”.
Is it man induced global warming? Is it the Solar Maximum? Is it the reduction in output of the earths magnetic protection? Or is it just a natural variation that has happened in the past, will go away & come back again sometime in the future.
Not every weather disaster is caused by man & anyone that says it is, needs to step back & think a bit more critically
Correct. But we have ensured that they are more extreme in every possible way.
Check out what’s happening in the Amazon right now, also the flooding in Vietnam, China, Myanmar and Thailand after Typhoon Yagi did a number on them in the past week.
