here’s from a scientific perspective as well

Why an ice age occurs every 100,000 years: Climate and feedback effects explained

The Milankovitch cycles

Supposedly we’ve had multiple ice ages according to this source, therefor multiple warmings, all before people were on the planet.

over the years more than once I’ve heard, climate skeptics say scientists in the the 1970s were saying we were heading toward an ice age,…

the reason scientists in the the 1970s said that an ice age was going to occur is because looking at the big picture of the solar system in geological time (ten’s to hundreds of thousands of years), THE RELATIVE POSITION OF THE EARTH IN AN ICE AGE PERIOD IS GOING TO BE FARTHER AWAY FROM THE SUN (THAN IT IS NOW), so the earth in effect will have less intense sunlight hit the surface, so its like an winter season that lasts for a really long period of time

(see 6th question,… why do we have a very real problem?)

once one understands the basic “physics,…” the math of “Climate Change” here on earth is rather straight forward,…

the big variable since the industrial revolution is ever increasing concentrations in the atmosphere of CO2 molecules due to the IR properties

Problem I see

If history according to science is true, then there should be no disagreements scientifically speaking. Problem is, what science is putting forward as science is not provable with irrefutable evidence science, but rather faith in science…which is a no no concept in scientific jargon
 
Thorium is not the answer. Only renewables will work.
Then again, maybe not.


At that rate of subsidy, to replace the 81% of US energy currently supplied by fossil fuels would cost about $1.3T, which assumes everything is scalable to that extreme, which is surely not so. Germany tried renewables and their electric rates skyrocketed. Wind and solar are assuredly not the answer.
 
sadly I seem to have confirmed the findings in a published paper (based on data gathered here in san diego) that there essentially zero understanding of the mechanisms that cause climate change in the public at large
How much understanding is there in the public at large about the mechanisms undergirding
  • Magnetism?
  • Gravity?
  • Themodynamics?
Why should we expect the general public to have much of an understanding of extremely complex scientific processes that aren’t particularly well-understood by the scientific community?

just thinking out loud, I gotta ask, I’d like to see the evidence for such a precise number.
Would you understand any of the evidence? I probably will not and science is my field of work.
If one doesn’t understand the subject but accepts it

In the broad scheme then

You’re not describing scientific knowledge, you’re describing Faith in science.

That is not true. Part of the scientific method is for theories to be challenged and put to further testing, especially when there are questions as to exactly what the evidence says. Disagreement is a normal part of the process.

Again you have science wrong. No theory is every “proven.” A scientific theory is either refuted by experiment or supported to some degree by experiment. No single experiment is ever the last word such that all future experiments are irrelevant. To be a scientific theory, an assertion must always be falsifiable. That is, there must exist, in principle, an experiment that could be performed where one of the conceivable outcomes is that it disproves the theory.

Therefore support for and provisional acceptance of a theory that has not been proven by “irrefutable evidence” is normal and expected, and is not some kind of anti-science approach.

Simple answer then, no absolute answer from science, then don’t absolutize science to answer/prove climate change. That would be faith in science, and faith is NOT a subject accepted in science

You’re not describing scientific knowledge, you’re describing Faith in science.
It is faith in reason that leads a person to accept a theory that he does not understand.

There are many instances where you are probably guilty of the same kind of faith. Take for instance the medical field. If you get a diagnosis based on a CT scan, you probably don’t understand the technical details of a CT scan or why the image they show you indicates the specific diagnosis. But in most cases you will accept that both of them are valid. Or, if you are in doubt, you may get a second opinion, or even a third opinion. But no matter how many opinions you get, you are still going to rely on the expertise of the professionals that are giving you the information. You have faith in the medical profession based on a reasonable track record the profession has had in the past.

Climate change science is no different. There are many experts in the field. Most people cannot be expected to fully understand the science behind their conclusions. For those people, the most reasonable thing to do is to examine the track record of those professionals and provisionally accept their conclusions based on that track record. In the case of climate science, there is a reasonably good track record, if you don’t start cherry-picking instances of failure. After all, one can cherry-pick instances of spectacular failures in the medical field, such as blood-letting to cure disease. But a fair survey of the results shows a track record that justifies the acceptance of their conclusions.

Now if you are a scientist doing research in these fields, the rules are a little different. Such a person is expected to understand the science behind other people’s research, and to question that research themselves, and not just accept it, even if it is the current consensus. The trouble is, many people here want to play at being a scientist without actually putting in the education to learn the field well enough to be able to be a scientist for real.

maybe in 100-200 years, when we’ve had significant breakthroughs in basic science.

We could be swapping out all coal generators with nuclear inside of 30 years.
Not saying renewables wouldn’t get a share, but they won’t meet base load needs globally.

Quickly and reliable swapping out coal would cut CO2 emissions by one third globally

I don’t know who you are addressing that to, but I have not seen anyone here claim that climate science or any other science is absolute and irrefutable.

plenty of people have supported the line that it’s settled science, some going so far as demanding legal actions against “deniers”. That approach relies on the position being irrefutable.
 
Flagged? Really? For what?

I am a human being as you are. Rather talk to me.

I don’t think anyone in this forum has said all of it is settled science. They may have said that some of it is strongly supported by evidence, but not irrefutable.

The medical example you use, (CT scan) is provable, it’s a seen result, it is not a guess nor a theory.

As for climate change theories, they are theories

Then in extension, one is free to reject any theory … correct?

Yup. That is the jest of it! Point is that we are rarely as smart as we think we are!
