Should we colonize Venus or Mars?
Venus-
Pros:
An Earth-like pressure in the upper atmosphere.
Higher solar panel energy production from above the clouds.
Thick atmosphere to aerobrake.
Venus is actually an easier and less costly colonization proposition than Mars is.
For one, the round trip from Earth to Venus would be 30 to 50 percent shorter than it would be to Mars. Just think about how much food, fuel, and time this would save - particularly when we're considering carrying enough supplies over there to set up a habitable environment.
Gravity on Venus is very close to Earth's.
Cons:
We have to change the atmospheric composition to make it more habitable.
To live on the surface, we have to cool the planet down this is much harder than heating it up. Venus is too hot for us to live on the surface, so we have to live (proposed) above the clouds (because it is close to the Earth's temperature). Here's how
a team of dreamers from NASA envisioned Venus colonization a couple of years ago. Basically, forget surfaces, let's all just live in huge, blimp-like airships high up
in the clouds:
1 Venus day is 116 Earth days and 18 hours.
No way to harvest water, or any other resource from Venus, Except for rocket fuel.
The very corrosive atmosphere.
No feasible of returning home*.
If a blimp fails then the crew doomed.
An extremely high pressure at the surface.
*Launching rockets from a blimp is not proven to work, let alone feasible.
https://www.sciencealert.com/should-we-be-trying-to-colonise-venus-instead-of-mars Mars-
Pros:
Can actually land.
Actual ground science possible.
Has a light atmosphere to aerobrake.
24.3 hour day
Resources harvest from ground and atmosphere.
Can actually return to Earth from the surface.
If a hab fails then the crew could potentially fix it.
Cons:
Really cold.
Hard to land without propulsion.
Lower solar panel energy production.
No magnetic field.
With no magnetic field, the atmosphere is very weak and so we have to develop an atmosphere after the magnetic field.

Arguments
Ultimately the goal of space exploration must be to go beyond the limits of our solar system, given that the Sun has a limited duration.
Perhaps it would be preferable to use Mars as a staging post for future outward space exploration.
Whereas the Venus proposition seems to be more of an exercise in relatively short term possibilities, rather than a sensible stage in what should be our long term objectives.

I'd also mention that because the planets orbit on different schedules, Mars is sometimes closer and easier to get to than Venus and it will vary depending on the orbits. I believe currently Mars is actually a little closer.

1. Mars has a very low atmospheric density (below 1% that of Earth) and a gravity too low to keep even an induced atmosphere for a long period of time. So terraforming of Mars into a planet with a climate similar to that of Earth may not be possible.
2. Similarly, extremely low temperatures on Mars due to a very low solar energy flux make it very hard to induce an atmosphere similar to that of Earth. Even if we were to increase the surface temperature to the Earth-like ones by introducing heavy concentrations of greenhouse gases trapping the solar energy in the atmosphere, those concentrations would make the atmosphere absolutely unbreathable.
3. Mars has a nearly zero magnetic shield, so everyone on its surface is going to be exposed to heavy cosmic radiation. While not a significant problem short-term, it is unknown what long-term effects on colonists permanently living and reproducing on Mars it may have.
Points 1 and 2 also apply to Venus, only in reverse.
However, the colonization model that is viable on Mars is building the domes insulating the internal environment, similar to how the ISS insulates its insides from the outer space, making the conditions inside habitable. Another model is an orbital colonization, where space stations are built to rotate around Mars - however this model would not be self-sufficient and would require a regular resource supply from Earth, which would be extremely expensive.
For any meaningful colonization to be even remotely possible, we must find a way to reduce the expenses on the inter-planetary travel by a few orders of magnitude, at least. And even then, a full-scale colonization of any planet to the level that people can live there naturally, without any special equipment, is likely to require extensive cybernetic or genetic enhancements. Humans are not made to survive outside the Earth's atmosphere, unfortunately, and there are not many ways for us to replicate that atmosphere anywhere else without involving very complicated technologies requiring constant difficult and expensive maintenance.

Even with the best conservation plan for earth any and all efforts will become short lived as the solar systems natural life cycle will bring about the Earths doom. By not doing something when the margins are in the favor of humanity would irresponsible. We can dictate the demand with greater caution. Taking into account the number of factures which accrue over time Mars is the only choice as our sun will grow, needing and taking more room, changing its effect on all planets in the solar system. Mars is the cushion as it has the longer window of operation in relationship to all cost factures.
Ideally a solar system space station would be built placed in an orbit between Earth’s orientation and the orbit of Mars in our solar system. This station could be an ongoing labor of love, while and on, after, and with the expedition to Mars taking place, think smart, be smart, with a doable pace, not about the quick achievement as the better goal for travel into the international universe.
@Emery Pearson mentioned efforts on the moon for colonization, this is a realistic testing ground for efforts which would be part of Mars. The idea is to set a list of hard by achievable goals to be reached in a sequence of events leading humanity up to living on Mars.
@Sear one of my shorter term goals is to create a debt clock that is actually associated to finance as the clock that is displayed publicly now, is not, It does not even reflect time let alone is it reflective of money, spending, or debt. A device of measurement of national debt as a time clock needs to be all four. Here again developing a Time for use in the universe can start with a much easier reachable goal on earth as far as testing mathematic calculation goes.

But cosmic heat death is over a billion years in the future, tens of millions of human generations.On the matter of global warming humanity may not survive one dozen generations.
I guess under ideal conditions billions of years off. So? I don't like to rush.
The problem according to the experts is, it may take centuries for Earth's climate to "return to normal", and by then the remaining 0.01% will have died off too
A problem according to honesty, the earth's climate will never return to normal, it is an unrealistic goal. The manipulation of climate is the least of all worries, of problems in need of clear resolution.
A second problem is the addressing of money as if it was gold, or lead it’s not.
To cut to the chase just asking me to put together a report on the viability, along with the procedures necessary to make the situation more realistic in understanding to you.
And to what purpose?
A United State of Constitutional Separation. We do not need one planets resources to leave the boundaries of our solar system, we need them all. All planet resources. America was called a new world, as our knowledge grew we lost focus on the expansion of open frontier. The environment is just more hostile deal with it.
It would probably be the single worst mis-expenditure of scarce social resources in all human history, all other human blunders would pale in comparison
Taxation is the world’s greatest blunder of human resources as it presents an idea that money can be spent more wisely by the group, then by the person. Politically it should also be known that a state of the union can be made up of inhabitants of space colonies. To increase the size of the Republic of United State's on a time table, we allow the procrastination of country to limit our understanding of responsible growth.
An assurance against the idea things are not always predictable is an asset, basic truth Mars is in the opposite direction of the sun, the sun is getting closer. this is a united state shared and presented by all science. We should act like it is true and start to move. looking dazed at the light will not help.

"The manipulation of climate is the least of all worries, of problems" J8
Pure ignorant buffonery.
What is funny is you are making a personal judgment from a list of priority, never pointing out earth can do both. The truth, the whole truth is no matter what is done about the trashing of this planet, or outer-space for that matter. It will not save the earth from the path of its destruction. There are a number of ways the end will come to this planet, it will however come to this planet, and keep coming until it arrives.
Any how the question is which planet should be screw up next after Earth, Venus or Mars?
I say Mars it will last longer, give more time to screw things up, and the colonies would make great additions to the United States of America. I think we need to do away with this whole democratic idea of bribery to convince countries to join in a Constitutional Union on Earth. Do like any other business with limited space and a need to expand, become creative on solutions.

Is this your attempt to dismiss the scientific consensus as a trivial, inconsequential matter of subjective preference? That sir would be "Pure ignorant buffonery." Nope.
The Scientific consensus is excluding general HVAK knowledge in temperature manipulation. The general HVAC knowledge is the practical experience and use of scientific understanding and data. In any real study of truth, no matter if science basic application it would be the first link between ignorance and impartial observation. Unless there was a pre-existing reason to avoid the comparison.
As for buffoonery it is the monkey who beat man into space but only displayed abilities to perform simple tasks of repetitive conditioning as Artificial intelligence. Basic principle being the best at being openly conditioned makes the subject the most intelligent of its kind? There is a question of honor which can be called into question with the applied application of science, at the least on occasion.
To change and unite our direction of discussion, as direction is without limit at this stage, drone application of construction might prove more valuable, more practical, with even greater responsibilities as calculation of time can expand by dimension to be translated in a universal way.
