BECAUSE GLOBAL WARMING IS NOT MAN MADE FOLKS!
now what are the ALBots gonna do?

Condensed is not the right word. A black hole is something that is created through implosion rather than inward pressure. The difference is that condensing something would mean that you can push it closer together until their electrons begin to repel each other. An implosion typically breaks away any bonds, and destroys the natural state of particles. Now if I understand it right, if Earth imploded the same way stars do to become black holes, would the gravity stay the same? Well you see, Earth's gravity is different at all levels, it is in fact strongest at its surface and weakest infinitely far away. It is tough to say at the center. Theoretically, there should be no gravity at the very center point because there is so little mass, if any to cause any actual gravity, mathematically, by Newton's equation, there is an infinite amount of gravity at the center. Most of our gravity relies on the geometry of the Earth, being that it is a solid sphere, with a certain radius. A black hole, derived from Earth's implosion would probably be a small, the size of a marble actually. The gravity should theoretically stay the same, but advancing science has proved it may have weaker gravity. This is because a lot of gravity is often focused into it's proximity and later gets really small as it leaves. The event horizon exists for a black holes and even light cannot escape. Simple energy considerations can give us a really general view of this. We know kinetic energy is 1/2mv^2 and potential energy is mgh. When we equate them together and solve for h, we get v^2/g=h, where g is gravity, v is velocity and h is distance from the source of the gravity. We also know that g=GM/h^2, where G is the universal gravitational constant, M is the mass of the Earth and h is simply the radius of the source of gravity. So now we have (V^2*h^2)/GM=h. If we fix up our equation, so we move variables around we get, v^2*h=GM. We then divide the velocity of both sides to get the h alone again. h=GM/v^2. Since we know that the velocity of the object must exceed the speed of gravity, we can calculate the inner bound of the black hole(this is where undoubtedly the speed of light cannot escape. The other methods are much more complicated). h=(6.67*10^-11)*(5.97*10^24)/(3*10^8)^2. Simply this and we get 3.98*10^14/9*10^16 and then we get .004 meters or not even half centimeter, as the distance of no return. You can try calculating for g to find out that much of the gravity is concentrated at this point, as a result, the gravity near the moon gets significantly weaker because much of the gravity is concentrated weaker. To calculate gravity just a few meters away, would require quantum mechanics. But at slightly differing points, you can expect it to drop significantly. The reason why gravity isn't the same at the moon is because we are no longer dealing with ordinary masses, the gravitational field bends spacetime, basically it stretches out space and time so that light cannot escape. This in fact means that gravity has a longer distance to go, which we cannot see. Space is stretched out, or otherwise it could not capture light.

This is a popular myth that is being put about by some climate change skeptics and I would urge you to look at the original NASA reports. Don't just read the headlines which state 'Mars Is Warming' but read the whole article.
Warming has been observed on SOME parts of Mars, at the same time cooling has been observed in others. The south polar ice cap is shrinking but the north polar ice cap is expanding - these are localised events, not global, and one more or less counters the other. There is beleived to be an overall warming trend but it's not related to events happening here on earth.
If you refer to the NASA reports you'll see that the explanation provided for Martian climate change is that of global dust storms which sweep across the planet for several days at a time. Such events are inevitably going to disrupt the climate, just as they would if such an event happen here on Earth.
What we do know and what is made vey clear (but convenienty ignored by some skeptics) is that the Sun is not the cause. If the Sun were to blame then the Moon would be warming, Mars would be warming across the planet and all other planets and moons in the solar system would be warming - they're not.
Only one other body in the solar system is experiencing global warming and that's Pluto, the reason for the warming here is a tripling of atmospheric pressure in the last 14 years.
Other bodies are partially warming but again, the skeptics take things out of context. They'll tell you that Saturn is warming but not tell you that it's a seasonal variation and only occuring on the part of the planet inclined toward the Sun.

Humanity does not have a monopoly on Global warming
Maybe the sun is having a stroke .
This does not alter the fact ,that Humanity DOES have an enormous negative impact on the Earths Environment
People keep bringing up the popularity of Global warming in the cosmos , and that many planets getting in on the act ,
In order to absolve Humans of any guilt from having behaved atrociously towards Mother Nature and the Natural resources we have .
the two concepts are linked ,but they are not ONE

Many people are using the warming on Mars as "proof" that Earthly global warming is caused by the Sun getting brighter. The only trouble with that idea is the numerous Sub observing satellites have not seen any solar brightening.
Nobody is saying that Mars is warming at the same rate as Earth. They are saying it is warming, but I have never heard anyone say it is at the same rate as Earth. While nobody is really positive why, a leading theory is that it is caused by Mars' axial tilt changing. Earth's tilt is stabilized by the presence of the large Moon, but Mars' two tiny moons are way too small to stabilize Mars' tilt, and it is believed to go thought much more dramatic ice ages and warm periods than Earth does as a result.

Well I was going to answer the question, but Trevor beat me to it. His answer is correct.
Your question is flawed because Mars is NOT warming at the same pace as Earth. You might as well have asked "Why is an earthworm as big as an elephant? An earthworm's momma isn't an elephant. Wazzup with that?! How can we make earthworms smaller than elephants?"

How dare you blaspheme? The state religion in America is environmentalism! You should repent immediately and for your penance you must recycle 100 beer cans and bundle up 100 newspapers!
Attached is a link on Mars. Mars is not heating up at the same rate as earth because it is further from the sun. Please get a clue, people!
YOU ARE BEING LIED TO!!! The earth is not overheating, we are not causing global warming, we are not going to die in floods, we will not die of fammine this is all a crock of B.S. and you are swallowing it hook, line and sinker!
Do you know when you should start worrying about carbon dioxide output or energy use or anything else? When you see people like Al Gore closing up his huge house and driving a electric car and not flying around it private jets. He is an expert on global warming and he hasn't changed his lifestyle at all. Why do you think that is? BECAUSE HE KNOW IT IS ALL A LOT OF NONSENSE!!!!!

Mars probably has different factors such as more CO2 which can increase the rate of warming on the planet. I don't think we can fight the warming of Mars just yet, due to our technology and the warming of our own planet. The Red Planet will have to wait another day.

The rotation is getting closer to the sun little by little. The suns gravity is so fierce that eventually we will all be fryed by it, not global warming.
