Any discussion as to how a small amount (or increase) in CO2 levels would affect climate would get very technical in a hurry.

If you are interested, you can read any number of sites on line about how greenhouse gases function and why a tiny amount can be pivotal.

If the CO2 composition were zero, our climate would be MUCH colder today.  And we'd not be here.
I really dont want to get a degree in this subject

just saying one of the reasons there are skeptics on this issue is the very small amount of man made co2 that currently exists in the atmosphere

They won't let me give blood anymore. The burnt orange color scares the hell out of the doctors.

I think the main reason some are skeptics is confirmation bias.  Incidentally, I think most of the "climate warriors" out there know almost nothing about this topic as well.  They are convinced it's a massive issue, and couldn't write a simple paragraph describing it that was technically accurate.

My step son in law told me CO2 levels were the highest in Earth's history.  I asked where he got that and he said Al Gore's movie.  I don't think Gore ever claimed that, and it's blatantly incorrect.  (Gore's movie IMHO really damaged the possibility of having any rational discussion about this topic, it became very politicized.)

CO2 levels are going to continue to rise no matter how many meetings and agreements happen.

Climate explained: why carbon dioxide has such outsized influence on Earth's climate (theconversation.com)

This is a pretty basic discussion of why CO2 at such low levels has such an impact.  This has been known for over a century.

Try this one: https://theconversation.com/climate-explained-why-carbon-dioxide-has-such-outsized-influence-on-earths-climate-123064

A few key paragraphs (intervening paragraphs omitted):

Quote
Scientists had already calculated that the Earth was about 59 degrees Fahrenheit (33 degrees Celsius) warmer than it should be, given the amount of sunlight reaching its surface. The best explanation for that discrepancy was that the atmosphere retained heat to warm the planet.

Tyndall and Foote showed that nitrogen and oxygen, which together account for 99% of the atmosphere, had essentially no influence on Earth’s temperature because they did not absorb heat. Rather, they found that gases present in much smaller concentrations were entirely responsible for maintaining temperatures that made the Earth habitable, by trapping heat to create a natural greenhouse effect.

-------------

People sometimes ask me why carbon dioxide is important for climate, given that water vapor absorbs more infrared radiation and the two gases absorb at several of the same wavelengths. The reason is that Earth’s upper atmosphere controls the radiation that escapes to space. The upper atmosphere is much less dense and contains much less water vapor than near the ground, which means that adding more carbon dioxide significantly influences how much infrared radiation escapes to space.

-------------


The influence of carbon dioxide can be seen in past changes in climate. Ice cores from over the past million years have shown that carbon dioxide concentrations were high during warm periods – about 0.028%. During ice ages, when the Earth was roughly 7 to 13 F (4-7 C) cooler than in the 20th century, carbon dioxide made up only about 0.018% of the atmosphere.

Even though water vapor is more important for the natural greenhouse effect, changes in carbon dioxide have driven past temperature changes. In contrast, water vapor levels in the atmosphere respond to temperature. As Earth becomes warmer, its atmosphere can hold more water vapor, which amplifies the initial warming in a process called the “water vapor feedback.” Variations in carbon dioxide have therefore been the controlling influence on past climate changes.

Some of my friends in Cincy were rather liberal and on occasion I'd ask them some basic questions about their belief set (climate change, assault rifles, how great Europe is, etc.)  They didn't much like my doing that.

I'm always a bit surprised how a human can arrive at such strongly held beliefs while knowing virtually nothing about a topic.  The main thing about climate change, for me, continues to be that we really aren't going to do nearly enough about it no matter what if it's a serious problem.

What is an assault rifle?
The laws provide a legal definition of what they mean.  The real assault rifle is the Sturmgewehr 43, the term meaning literally "assault rifle" (and following guns of that general ilk).

Basically, it's a rifle that looks really scary.

 the only legal definition Ive found says an assault rifle is a military weapon that is fully automatic

The former Federal law banning the sale of new ones had a different definition based on "features" like a bayonet mount or barrel shroud or detachable magazine or adjustable stock, none of which really relate to lethality.

And weapons like the M-16 have a "select fire" switch that isn't really fully automatic past three rounds.

The real point is that they are rarely used to commit gun crimes, the percentage is single digit, lower if you count suicides.

I have one of those, takes 556 NATO, but I wouldn't call it an assault rifle at all. It's never been used in an assault, never will be, and likely wouldn't be used for self-defense either.

Is a shotgun an assault weapon? Could be.

9mm pistol? Could be.

.380 pistol? Could be.

Weapons don't shoot on their own.

Definition of what’s an 'assault weapon' is a very contentious issue (cnbc.com)
Definition of what’s an 'assault weapon' is a very contentious issue (cnbc.com)

The 1994 federal assault weapons ban, officially known as the Public Safety and Recreational Firearms Use Protection Act, was passed as a crime-fighting bill and identified more than a dozen specific models of firearms, including the Colt AR-15, that were defined as semi-automatic assault weapons. It also defined the term by specific characteristics, such as the ability to accept a detachable magazine and by certain cosmetic features.

They were defined as having two or more features like a bayonet mount of pistol grip etc.  Anyway, another topic.

I believe you
but, once in a great while, these weapons fall into the wrong hands
banning and taking all the weapons used in school/mall/mass shootings off the streets is just not realistic.

folks aren't willing to give up their guns and politicians aren't willing to be voted out of office to try to make it happen

similar to term limits
there's really no use wishing there were no guns available to be attained by criminals that will do whatever is needed to obtain them

including smuggling them over the open southern border
