I know people prefer to believe the narrative from the news medias but sometimes the truth is elsewhere;
The globalist Davos World Economic Forum is proclaiming the necessity of reaching a worldwide goal of “net zero carbon” by 2050. Yet transformations underway from Germany to the USA, are setting the stage for creation of what is called the New Word Order. In reality it is a blueprint for a...

We know there are many factors, and also I think we don't know them all, as I said above.
But, here's my thought..... Let me use a very good analogy that exactly fits, and tell me what you think....
Analogy:
Suppose you arrive to find your home is very warm -- in fact, really uncomfortably warm. (Perhaps it will turn out that a visiting 5 yr old grandkid before ya'll left the house the day before was curious and experimented by turned up the thermostat to 92F....)
Ok, what to do.
You check the programmable thermostat, but find it's already automatically set itself to the daily temperature reset (a nice setting of 72F maybe)....
Why not open the window and let some heat out?
What's your idea at this moment?
--------------------------
Climate is quite complex, but we can understand some/several important factors (even if we don't know all of them yet, as I suggested in my OP).
(If you already know the data (graph below), and if you already know the mechanism for infrared absorption, you'll still want to see the fascinating section on
VENUS at the end)
One factor must be CO2 due to the observed and well understood fact that it absorbs and the re-emits infrared in a random new direction (so that infrared that had been traveling upward toward space but hits CO2 will then be re-radiated, so that about 1/2 will be aimed back downward towards the surface of Earth below).
Here's the temperature trend since about 1850, also graphed with CO2 in the atmosphere:
Yearly temperature compared to the twentieth-century average (red bars mean warmer than average, blue bars mean colder than average) from 1850–2022 and atmospheric carbon dioxide amounts (gray line): 1850-1958 from
IAC, 1959-2019 from
NOAA ESRL. Original graph by Dr. Howard Diamond (NOAA ARL), and adapted by NOAA Climate.gov.

For those interested, before looking at Venus, here's a brief Discussion of how this process works. (off the top of my head, from my background in physics):
It's experimentally known (fact) (and long understood also with old, well tested physics theory) that CO2 gas absorbs and re-emits infrared radiation in a random new direction.
So, what happens then is that sunlight/radiation that reaches the surface of Earth warms the surface due to absorption of that sunlight/radiation (the portion not reflected away). Next, that surface having been warmed by sunlight then radiates more infrared radiation proportionally to its warmed temperature.
This was discovered experimentally long ago.
The first quantitative conjecture based on experimental observation of hole radiation was:
Stefan’s Law (1879):
the total power P radiated from one square meter of black surface at temperature T goes as the fourth power of the absolute temperature:
P=σT^4, σ=5.67×10−8 watts/sq.m./K4.=4, =5.67×10−8 watts/sq.m./K4.
Five years later, in 1884, Boltzmann derived this T^4 behavior from theory....
So, as a surface heats up, it radiates more energy outward, and one key part of the spectrum of interest to us is the
infrared, where a significant portion of all the radiation will be emitted, and normally could travel upwards through an atmosphere out into space, helping remove heat energy, so that if all the radiation radiated upward could escape, then the surface would reach equilibrium at some certain temperature, which we call the
'Blackbody Temperature'....
Now, since an atmospheric gas like CO2 is able to absorb and re-radiate infrared in all directions, for a given surface temperature below, the CO2 will reduce the total infrared escaping out into space since some of that infrared is re-directed by the CO2 back downward towards Earth's surface, where some of it is then absorbed near or on Earth's surface where it will help heat up both the nearby atmosphere and the surface more as some of that redirected infrared is absorbed.

fun example:
VENUS -- Atmosphere: > 96 percent carbon dioxide and about 3.5 percent molecular nitrogen.
A fascinating example is Venus -- since Venus has far more CO2 in its atmosphere than Earth, that much higher level of CO2 traps far more heat on Venus than does Earth's atmosphere, so that Venus is far hotter than it would be without so much CO2.
If Venus did
not have something in its atmosphere to trap infrared, then Venus's average surface temperature at it's distance from the sun would be near to the its blackbody temperature at that distance from the sun, much closer then to the blackbody temperature for that level of sunlight (where Venus orbits) resulting in a
blackbody temperature nearer to ~250 Kelvin.
But Venus is far hotter than ~250 Kelvin, due to heat trapping in its atmosphere.
The measured (by Russian probes) surface temperature of Venus is about ~ 740 Kelvin.
