Carbon dioxide is better at transferring heat than the gas composition of the earth’s atmosphere. Almost as good as water vapor (steam).
Also, Venus just happens to be much closer to the sun than the earth is, which people don’t seem to take into account.
The earth would probably look much the same if it was in the same orbit as Venus.
Of course our being 3rd from the Sun vs 2nd plays a major role in our temp vs theirs.
As an aside, did you know that there actually is ice on Mercury, the 1st planet from the Sun?

No one has shown any evidence that taxing carbon dioxide emissions has any effect on climate. If someone really wanted to cool the climate they could include an additive in jet fuel and freeze us all to death.
Hawking must have found a solution to his quantum cosmology equations that allow the earth to move closer to the sun. That’s the only way the earth becomes remotely like Venus.
Not if God doesn’t allow it.
LOL! Well, somethings are worth repeating. Showing the worlds most genius man to be a dolt works. Besides which, we don’t “make” new stuff. We just jockey it from one plane/state of existence to another.
Someone should tell the guy to go take a hike.

Oh, good grief. That is such hokey science, it is worse than the Hawking comments. STATIC air pressure (of non-greenhouse gases) does not cause high temperatures. Otherwise your car’s tires would be warmer than surrounding air, just sitting in the garage overnight. And, Jupiter’s atmosphere would be much hotter than it otherwise is.
Additionally, there is NO QUESTION that CO2, Methane, etc., absorb long wave light radiation, while nitrogen and oxygen are relatively transparent to such. Atmospheric composition, at least at some point, DOES matter. The questions are what other factors are at work? For example, what triggers the recurring periods of glaciation Earth has recently experienced? Are we preventing or delaying the next period of glaciation? — just possible, IMO. Is there any evidence that in the next few hundred years, for any reason, Earth is likely to warm to “Cretaceous Optimum” levels? (No, and “runaway” did not occur then or in earlier even warmer periods.)
I am not worried about over 100 years out: By then, even if temperatures are deemed “too warm” we will have the ability to incrementally shade (or sunbathe) the Earth as and IF needed — and if we don’t have that ability, then we’ve screwed up and deserve a little discomfort - if there even is any.
But atmospheres are not static. Also, the total heat content of a system is directly related to the amount of matter present. The air on Venus is almost a hundred times more dense. More density, more matter.
CO2 is a trace gas; it is, at most, about one-half of one percent of the atmosphere; mankind is responsible for about five percent of all the CO2 in the air.
We cannot effect the Earth's climate short of igniting every nuclear device on the planet, and even that would be temporary. So "we" are not delaying glaciation, nor are we heating the earth beyond isolated urban heat islands.
Even if we could effect climate, what is "optimal?" What is "normal?"
Future generations, long after the politicized media, scientific, and other institutions have lost their propagandist grip, will smirk at us and our superstitious Global Warming hysteria in a way not unlike how we view primitive cultures who are terrified of eclipses.
Venus has an atmosphere the opposite of Earth, instead of CO2 being less than 1 percent of the atmosphere, it is the reverse. We would have to kill all plants and force volcanoes all over the earth to erupt, and our atmosphere would still not be like Venus.
The Sun’s mass converts into energy, meaning that it’s gravitational pull on all planets weakens.
In my experience, loser-folk pretend to admire hawking to make themselves seem smarter than thou.
