Why are 'science people' preaching about climate change but cool with terraforming Mars?

Many of them anyway.
There is nothing we can do to the Earth that will make it worse than Mars.
Red Planets Matter

Have they even asked the Martians if that would be something they would like?

It's like socialism, I'm pretty sure they'll get it right next time.

No. Apparently some ecosystems are more equal than others.

If humans are horrible and are destroying earth why would they want to spread that to Mars?

I bet many of the people "marching" today about how important science is ignore it when it comes to gender.

This thread actually seemed like a good idea to you?

Why didn't Science people bitch about Obama cutting NASA??? Is that not science??

uhmmm making an uninhabitable planet habitable, and making one that is uninhabitable

This is such a stupid question and you should feel bad about it.
"Why is murder such a bad thing when no one complains when I shoot a mound of dirt!? Checkmate, science!"

There are real ethical questions about changing Mars, discussed in the science community. Do people think we have a right to do what we want to the Solar Sytem? Not that we have that power.
People are hot and bothered about the idea of us tinkering with Earth while at the same time having no problem tinkering with Mars. It seems hypocritical.
Even after widescale nuclear war the Earth would still be a better place to live than Mars.

Can we stop seeing memes on fb and bringing them over here as an original thought?

Well Earth is our home planet.
Mars is like a rental car, you are gonna push the limits with it, if you break it, it's somebody else's problem

Because scientist don't know what space is really like. As my favorite scientist once said:

I have relatives who are marching in this bull shite. I saw more crickets than I did people in the pictures.

No, there are not. The only Ethical questions are in regards to us doing that on mars is if there is alien life there that developed on its own. Either way, it will eventually be irrelevant as the risk of us contaminating what would at most be microbial life on earth will outweigh our needs as a species. There are no ethical questions regarding a lifeless planet/rock/whatever in space.

Respectfully, you simply aren't well informed about this issue.
Thr ethical question exists independent of the presence of Martian life.
Can you expain to us which of humanity's needs will be met by colonizing a planet that doesn't have a functioning magnetosphere? How will we deal with the lack of shielding for solar radiation in such a way that will create a living environment that is 'meeting our needs' in a manner that can't be accomplished on Earth?

Before reading this, remember that humanity has barely pierced the surface of the Earth in a relative sense.

So, how could we jump start Mars’s magnetic field? First we would have to somehow liquefy the outer core of the planet. Then the planet’s own rotation would create a dynamo and generate a magnetic field like Earth’s. This could be done using an extremely large nuclear bomb which would be placed near the core of the planet. The bomb would have to release enough energy to liquify the core, that’s A LOT of energy! This is similar to the premise of the movie “The Core”. In that movie they were trying to get the molten core of the earth spinning to restart the dynamo where we would have to melt the core of Mars first. Another interesting idea is to run an electric current through the planet. The resistance of the core would cause it to heat up, similar to how a wire heats up when you short circuit a battery. Again, this would take a lot of energy but this way it would be delivered by electricity which could use solar or some other power source. Say we were to somehow terraform Mars for habitation. We could warm it up and give it an Earth like atmosphere and a magnetic field to protect it from solar wind, but would the atmosphere stick around?
My intuition tells me, unfortunately, no. Even with a magnetic field Mars is just not massive enough (1/10 the mass and ~0.4 the gravity of Earth) to hold on to an Earth-like atmosphere at Earth-like temperatures. Escape velocity for planets in the Solar System Escape velocity for planets in the Solar System vs. their surface temperatures. Credit: Cmglee, Source, license: CC BY-SA 3.0. You can see that on this plot of atmospheric temperature vs escape velocity, also reproduced on the right. The dots represent the planets (or moons) in our solar system and the lines show the temperature and velocity at which different gasses will escape. Any planet that lies under a line in this plot cannot hold on to that specific gas. If we were to warm Mars up to something like the temperature of Earth so that liquid water could exist on the surface, we would move the point on the plot horizontally so that it is under the earth. At this temperature, Mars could not hold on to water in its atmosphere, and nitrogen and oxygen would be very close to the limit. If we don’t care about the atmosphere being like Earth’s, then a magnetic field would definitely help protect a warmer CO2 atmosphere from solar wind, but this would be a drastically different atmosphere than Earth’s.
